In the dark sea.

Two balls of soft light illuminated an area of ​​ten feet in radius.

A token on Su Mu’s waist emitted a faint light, forming a circular light curtain that enveloped him.

People can breathe freely in it.

He spent one hundred taels of gold to buy this token from the Chunfeng Gang under the Nanhai Sect. It is the certificate for entering and exiting the Coral Ghost Market.

It has a built-in water-repellent formation that allows people to move freely underwater, which is truly magical.

The Nanhai Sect was able to occupy Zhuya Prefecture, which shows that it had quite a bit of background.

Even Su Mu couldn’t make this kind of token.

Of course, even without the token, with Su Mu’s ability, he could move freely underwater.

It’s just that he didn’t want to show his skills in front of Han Jieren.

Han Jieren seemed to have the same idea. He did not avoid the water himself, but activated a token on his waist.

Unlike Su Mu’s wooden token, Han Jieren’s token was obviously much more delicate and looked like it was made of some special metal material.

Come to think of it, with Han Jieren’s identity, how could he use such a consumable wooden token?
The water-repellent spell of this wooden token will become ineffective after being used several times, and it will completely turn into a piece of rotten wood.

Han Jieren’s token can obviously be used repeatedly.

“Master Han, does your Nanhai Sect have a master who is proficient in formations?”

Su Mu suddenly asked.

Han Jieren paused for a moment before turning to look at Su Mu and pretending to be calm, “Why do you say that, Lord Su?”

“If you are not a master who is proficient in formations, it is probably impossible to imprint a water-repellent formation on a small token like this.”

Su Mu said.

The formation does not get bigger as it gets bigger.

Sometimes, if you want to arrange it small enough, you need a higher level.

An array formation is extremely complicated. Imprinting it on a small token is like carving a picture on a grain of rice. It can only be done by a master.

“Practice makes perfect.”

Han Jieren said, “This kind of water-avoiding token has been passed down in the Nanhai Sect for many years, and it does not require a master of formations to make it.

Of course, this involves the secrets of our Nanhai Sect, so it is not convenient for me to tell you too much, Master Su.”

Su Mu smiled indifferently. He already had the answer he wanted.

Han Jieren should be the person from Nanhai Sect who is proficient in formations.

I don’t know if this Han Jieren has any relationship with Xu Yu from Tingchao Pavilion.

If there is a connection, it will be fun.

Han Jieren had better not try to deal with Ao Qing, otherwise, Ao Qing would definitely let him see what a real dragon is.

…………

The ancient shipwreck ruins that Liu Yishou mentioned are some distance away from the Coral Ghost Market.

It took Su Mu and Han Jieren five days to find the place.

The water-repellent token on Su Mu’s body had long been ineffective, so he asked Han Jieren for another one without hesitation.

As the second most important figure in the Nanhai Sect after the Dragon King of the South China Sea, he naturally had this water-avoiding token on him.

The dark seabed was illuminated by the light emitted by the water-repellent token.

There are fish swimming around constantly, and occasionally you can see one or two water monsters.

However, those monsters are lazy and will not attack people unless you provoke them.

“Fortunately, there aren’t many monsters here.”

Han Jieren said, “If we were to go to other places where water monsters were lurking, it would not be so easy for us to get close.

Of course, Master Su, you are an expert in dealing with monsters, and you are not afraid of them.”

Su Mu did not comment, but just looked at the sunken ship in front of him quietly.

This sunken ship was more than ten feet long and was already covered with blue-black algae.

It has no idea how many years it has been sleeping on the seabed.

The hull was broken in the middle, and it looked as if it had been hit by a huge force.

Han Jieren walked to the place where the shipwreck was broken and observed it carefully for a while.

“It looks like it was damaged by human hands.”

Han Jieren said, “I’m afraid this ship has encountered a strong enemy.”

“Sword Intent.”

Su Mu reached out his hand and touched the broken part, feeling the slight pricking sensation on his fingertips. He pondered and spoke.

This shipwreck has been sunk for who knows how long, and the sword intent has almost dissipated.

If Su Mu had not already mastered the Jiuyi Sword Domain, he might not have been able to detect the remaining sword intent on the sunken ship.

“Sword Intent?”

Han Jieren showed surprise on his face.

A scene seemed to appear in his mind, in which a ship was sailing on the endless sea.

At this moment, a strong man suddenly fell from the sky and cut the ship in half with just one sword.

“If it was man-made, then could the treasures on the ship have been taken away by someone?”

Han Jieren thought about it.

If the ship sank due to wind and waves, the people on board might also be buried at the bottom of the sea, but the things on the ship might be preserved intact.

But if they encountered an enemy, it is not certain how much of the things on the ship would be left.

“You’ll find out once you go in and take a look.”

What Su Mu hated most was guessing. He took a step forward and entered the interior of the sunken ship.

Seeing Su Mu like this, Han Jieren did not dare to delay and hurriedly followed him in.

Explore the ruins, whoever finds it first owns it.

In this sea area, if facing someone else, the Nanhai Sect could still take the shipwreck for themselves.

But facing Su Mu of the Taiping Division, the Nanhai Sect couldn’t do so even if they wanted to.

Han Jieren now only hopes that he can act quickly and grab all the good stuff in the shipwreck first.

When Han Jieren couldn’t wait to enter the interior of the shipwreck, Su Mu had already swam to the deep end of the shipwreck.

After hesitating for a moment, Han Jieren went towards the other half of the sunken ship.

Competing with Su Mu is not a good choice.

Each person searches half, and the harvest depends on their luck.

Su Mu naturally noticed Han Jieren’s actions. He just smiled slightly and continued searching forward.

Mars Blood Sand is also a very rare treasure for Su Mu.

Not only can it be used to forge weapons, but also to make elixirs. It is a rare treasure.

Moreover, Su Mu sensed a faint astrological power in the Mars blood sand.

In other words, the Mars blood sand is very likely to contain the power of the stars. If it can be extracted, it can help warriors improve their strength.

Of course, the astrological power in a grain of Mars blood sand is too little to have any effect.

Only a large amount of Mars blood sand can play this role.

The reason why Su Mu was so interested in this shipwreck ruins was, firstly, because of the Mars Blood Sand, and secondly, because the Mars Blood Sand was not an ordinary thing, and the person who possessed the Mars Blood Sand was definitely not an ordinary person.

There may be other precious things on this ship.

Wow!
Power surged in Su Mu’s body, and streams of water began to wash around him.

He had already mastered the artistic conception of Kanshui, and the Four Symbols Divine Body and the ability to control water that he had cultivated were still there.

The water flowed like a finger, washing all the mud, sand and algae in the cabin out of the cabin.

After a few breaths, everything in the cabin was exposed from the mud and sand.

Skeletons were lying all over the cabin, some were completely shattered by the water flow, while others had a jade-like luster and remained intact under the impact of the water flow.

If a warrior has practiced successfully, his bones will be as hard as jade and will not decay for a thousand years.

There are quite a few warriors with high levels of cultivation on this ship.

It is not known whether they died in the storm or were killed by someone.

Only bones are left, and it is difficult to find out the cause of their death.

Su Mu was not interested in the cause of their death.

His eyes fell on the lucky machines hidden on the cabin walls.

Liu Yishou did not lie.

There are indeed many opportunities for good fortune in this ancient shipwreck.

As soon as this thought came to his mind, Su Mu suddenly realized that something was wrong.

Since Liu Yishou and others have already captured the lucky machines from the ancient shipwreck, why are there still so many lucky machines here?
With Liu Yishou’s businessman style, he would definitely not leave anything valuable here.

Unless, he didn’t even enter the cabin.

Why didn’t Liu Yishou go into the cabin?

Knowing that there might be good things in the cabin of the sunken ship, how could Liu Yishou, with his greedy nature, give up?

unless–

Just at this time.

suddenly.

Su Mu heard Han Jieren’s angry shout.

Along with it comes the sound of rushing water.

Su Mu suddenly felt a sense of alarm in his heart and his body suddenly turned sideways.

Swish!
A tentacle as thick as a child’s arm pierced his cheek and with a bang, a big hole was pierced in the wall of the ship.

The sea water rolled, and in an instant the water in the cabin became so turbid that you couldn’t see your hand in front of you.

Su Mu’s eyes flashed, and the fire spear instantly appeared in his hand.

The gun barrel shook, stirring up a stream of sea water and rushing forward.

There was a loud bang.

Su Mu felt a huge force coming from the front, and he involuntarily took two steps back with a look of surprise on his face.

With Su Mu’s current strength, holding a fire spear, he was forced back two steps.

You know, although his Eight-Nine Mysterious Arts has not yet achieved a small success, his physique has already reached the peak of the fusion realm.

Coupled with the power of the Fire Spear, ordinary strong men in the Fusion Realm are no match for him in terms of strength.

Before Su Mu could think too much, the sea water in front of him was already surging like a mountain pressing down on his head.

In the sea water, there were tentacles flying up and down and circling, filling the entire cabin.

Boom.

Amidst the loud noise.

Two figures flew backwards from the cabin and flew hundreds of feet before they managed to steady themselves in the turbulent sea.

Those two people were Su Mu and Han Jieren.

The two looked at each other, both of them looked a little embarrassed.

Two people were exploring the ruins of an ancient shipwreck. They were still on guard against each other, but they never expected that they would be driven out before they found anything.

Shame on you.

“Master Han, didn’t Liu Yishou tell you that there is such a thing here?”

Su Mu changed the subject and spoke.

Han Jieren obviously didn’t want to talk about the embarrassing thing just now. He coughed and said, “Liu Yishou is a pure businessman. He only told me that there might be danger here, and didn’t mention the situation inside the sunken ship.

I was careless. “

I was just busy competing with Su Mu for the lead and was careless.

Otherwise, how could I not realize such an obvious problem?

It only takes a little thought to realize that if there were no danger, this ancient shipwreck would have been plundered by merchants like Liu Yishou long ago.

But he was too confident. He initially thought that the danger in the eyes of Liu Yishou and others might not be a danger to him, Han Jieren.

Unexpectedly, I almost stumbled.

“Master Su, did you see clearly what attacked us?”

Han Jieren said.

Fortunately, he was not the only one who was embarrassed.

Even the famous Su Mu suffered a loss, so it was not shameful for Han Jieren.

Only the two of them know what happened today. As long as they don’t say anything, no one else will know.

Han Jieren made up his mind not to mention the embarrassing incident just now.

“What attacked me were a lot of tentacles that looked like an octopus or a squid.”

Su Mu groaned and said, “Judging from the length of its tentacles, its size should be larger than this ship.

And it’s extremely powerful, I estimate it’s at least a sixth-level monster.”

Su Mu had heard people say before that the monsters in the sea were more powerful than those on land.

Now that I see it, it is indeed well-deserved.

I casually encountered a monster of at least level six.

You know, on land, sixth-level monsters are extremely rare.

“It should be hidden in the mud under the ship.”

Han Jieren said, “That’s why we didn’t discover it just now.

It is not uncommon to see huge monsters in the sea, and this monster is not an exaggeration.”

He looked at Su Mu and asked, “Sir Su, are you sure you can kill it?”

It was obvious that this monster had regarded the remains of the shipwreck as its own lair, and anyone who tried to touch anything inside would be attacked by it.

If you want to get the things inside out, you have to kill this monster.

Su Mu remained silent and did not comment.

He was thinking back to what he had just seen in the shipwreck.

Before the monster attacked him, he had cleaned part of the cabin and saw a few things besides the skeleton.

Is it worth it?
He was weighing the pros and cons in his mind.

“This monster is quite powerful. I am not sure.”

Su Mu said slowly, “Maybe there is a way. Lord Han, you can lead it away, and I will take the opportunity to take this sunken ship away.”

Han Jieren: “…”

Do people say it?
I take the risk and you get the benefits?

I guess we’re not that familiar with each other yet.

I don’t trust you to that extent yet.

“Sir Su, it’s not that I’m refusing, it’s just that my ability is limited.”

Han Jieren said seriously, “With my strength, I am afraid I can’t hold out for three breaths under such a ferocious monster. Wouldn’t that ruin Lord Su’s plan?”

Su Mu glanced at Han Jieren. “Limited strength?” You just escaped from the cabin of the sunken ship, but your movements were not slow at all.

The monster was very powerful. Even Su Mu almost suffered a loss in its sudden attack just now. Han Jieren not only escaped, but also did not seem to be injured. His strength could not be said to be weak in any way.

He definitely has the strength of the fusion realm, and is a leader among them.

However, Su Mu also knew that he and Han Jieren had no trust in each other, and it was impossible for him to let Han Jieren take the risk to lure the monster away.

What he said just now was just a casual test.

“There is another way.”

Su Mu said slowly, “My Taiping Division is good at beheading monsters. I’ll have someone come over and work together to kill this monster.”

Han Jieren couldn’t help but glance at Su Mu, his eyes full of resentment.

Do you think I’m a fool?
If you ask the people from the Taiping Division to come here, then what role will our Nanhai Sect have?

Besides, you let people from the Taiping Division enter the South China Sea. How could I not know what your plan was?
By then, it may be easier to invite the gods than to send them away.

Once the Taiping Division enters Zhuya Prefecture, it will probably take root there.

The Nanhai Sect has always been unwilling to let the Taiping Division take control of Zhuya Prefecture. How could they give you a chance just because of a small shipwreck?

“Of course it’s better to deal with this monster with more people.”

Han Jieren said, “But if there are too many people, I’m worried that it will attract more monsters.

Lord Su, you don’t know much about the sea. The number of monsters in the sea is definitely much greater than that on land.

And they are quite sensitive and will flock to you at the slightest smell of blood.

That would not be a good thing for us.

Besides, the remains of an ancient shipwreck are not worth mobilizing so many troops.”

“Master Han, do you have any good ideas?”

Su Mu said calmly, “Or, do you think we can kill this monster together?

To be honest, I don’t think I can do it.

Of course, if you have enough confidence, Master Han, I can also help you.”

Han Jieren complained in his heart, everyone knows that you, Su Mu of the Taiping Division, are unrivaled in the world in fighting. Even Liang Jinglue, the national master of the Demon Court, suffered a great loss at your hands. The Demon Lord and the Xuan Emperor both want your life, and yet you are still alive and kicking.

Now tell me, you can’t even kill such a monster?

Aren’t you just deliberately unwilling to show your true abilities?

Han Jieren’s brain was working.

He now suspected that there was something extraordinary in the shipwreck, which was why the monster was lurking here and why Su Mu was so interested in the shipwreck.

It would definitely not work to ask people from the Taiping Division to slay the demon.

It is not convenient to transfer the manpower of Nanhai Sect now.

The Dragon King is about to abdicate, and various forces want to compete for the position of the new Dragon King. Now the strong men of the Nanhai Sect will not move easily.

The most important thing is that Han Jieren is unwilling to let other strong people from the Nanhai Sect interfere in the affairs here.

If they were allowed to intervene, wouldn’t they have to share a share of the spoils from the ancient shipwreck ruins?
Now that the old Dragon King and the new one are taking over, Han Jieren also wants to try and see if he can take one more step forward.

To move forward, one needs a solid foundation, and Han Jieren’s foundation is slightly insufficient.

Now encountering this ancient shipwreck may be an opportunity given to him by God.

If he could get some rare treasures from here, then his chances of moving up would greatly increase.

Thoughts flashed through Han Jieren’s mind.

“Master Su, I have a way that we can try.”

Han Jieren finally made a decision and said in a deep voice.

“any solution?”

Su Mu asked casually.

“I know a little bit about formations.”

Han Jieren said.

A look of “as expected” flashed across Su Mu’s eyes.

Han Jieren pretended not to notice the mockery on Su Mu’s face and continued, “I can set up a formation to trap this monster.

But my formation should not be able to kill it. If I want to kill it, I need you, Lord Su, to cooperate with me.”

“I understand.”

Su Mu said, “You mean your formation can restrict it and give me a chance to attack.

It’s like we work together to kill it, and then we can divide the contents of this ancient shipwreck between the two of us.”

“Yes.”

Han Jieren nodded and said, “Let’s be frank.

Lord Su, you are of a very special status, and you may not be interested in the things in this ancient shipwreck, but I, Han, come from a humble background…”

“I like it, but I don’t like it. Why are you and I here?”

Su Mu said, “Sir Han, no matter how humble your background is, can you be worse than me?

Back then, I was just a hungry and poorly clothed refugee in Wuling City.

I am also very poor now, and I like everything here. “

Han Jieren: “…”

He didn’t expect Su Mu to be so direct.

However, thinking that Su Mu also came from a humble background, Han Jieren actually felt a sense of mutual respect.

“In that case, let’s work together to kill this monster. As for the things in the ancient shipwreck, we will distribute them according to how much each person contributed. What do you think, Lord Su?”

Han Jieren said seriously.

“Very good.”

Su Mu nodded and said, “Now let me see your attainments in formation, Lord Han.

To be honest, I have only seen military formations, and the only real formation I have seen is a teleportation formation. I have never seen any other formations, so today is a good opportunity to broaden my horizons.”

“I’m afraid I’ll disappoint Lord Su. I only have a little understanding of it.”

Han Jieren said, “I am not as talented as you, Lord Su. I am just an ordinary person. Although I have learned some formations, I am far from being proficient in them. Today I am just trying it out with reluctance.”

As he spoke, he took out some items from his arms and began to observe the shipwreck, constantly calculating the direction by pinching his fingers.

Su Mu observed Han Jieren’s movements with interest.

Su Mu had just seen Xu Yu setting up a formation not long ago. Now looking at Han Jieren’s movements, they were somewhat similar to Xu Yu’s.

However, Su Mu did not understand the formation, so he could not see the similarities and differences between the two formations.

“It would be nice if I could learn some formations if I had the chance.”

Su Mu secretly said in his heart that the art of formation also has the power to seize the fortune of heaven and earth.

Unfortunately, it seems that there hasn’t been a powerful formation cultivator in the world for a long time.

Even if there were one or two warriors practicing formations occasionally, they were unable to practice the formations to a high enough level.

Su Mu was a little curious and wondered to what extent Han Jieren had practiced the formation.

I heard that when the formation is practiced to a certain level, it can trap people at the fusion realm or even those with stronger cultivation levels to death.

I remember that the summoning circle in the Demon-Slaying Sword could even summon big cat monsters from the Taixu Holy Land.

Just imagine if someone could set up this kind of formation, wouldn’t they be able to communicate with the Taixu Holy Land at will?
If this were true, Li Guichen’s lifelong pursuit would become a complete joke.

Han Jieren kept moving around the ancient shipwreck.

However, the monster in the ancient shipwreck did not attack.

Su Mu had discovered this before.

After they withdrew from the ancient shipwreck, the monster retreated and did not continue to chase them.

I don’t know whether it is because it dares not to leave the ancient shipwreck or is unwilling to leave the ancient shipwreck.

But that’s a good thing.

At least it would allow Han Jieren to concentrate on setting up the formation.

Every time Han Jieren set up a formation point, he would calculate for a while before he could determine the next formation point.

If the monster launched a sneak attack, he would have no time to set up the formation.

Su Mu seemed to understand why the formation cultivators disappeared in the long river of history.

Not to mention anything else, just the speed of setting up the formation is simply impossible to complete in battle.

Formations may only be suitable for being set up in fixed places, and not for use in battle.

Of course, it is also possible that Han Jieren’s formation skills are not good enough.

Just as Su Mu was thinking, Han Jieren finally completed the arrangement of the formation.

He returned to Su Mu, wiped the sweat from his forehead, and his face turned slightly pale.

Obviously, in order to set up this formation, he consumed a lot of energy.

“Master Su, are you ready?”

Han Jieren said in a deep voice, “Once my Weak Water Abyss Formation is deployed, the water within the range of the formation will become thousands of times heavier, and the movement of monsters will become extremely difficult.

As long as you take this token of mine, you will not be affected by the formation and can move freely within it.”

“Double the gravity?”

Su Mu pondered.

“It’s not doubling gravity, but it’s similar to doubling gravity.

This Weak Water Abyss Formation can only be performed in water.”

Han Jieren said, “Logically speaking, the effect might be better if we use the Four Symbols Soul Locking Formation, but the current conditions do not allow it. There are too many things needed to set up the Four Symbols Soul Locking Formation.”

Su Mu nodded thoughtfully.

From what Han Jieren said, if he had the materials to set up an array, he could also create a powerful array.

It turned out to be the right decision not to act rashly against the Nanhai Sect.

Just because Han Jieren couldn’t set up a stronger formation here didn’t mean he had no way to do it in Nanhai Sect.

A terrifying formation must have been set up around the Dragon King of the South China Sea’s Dragon Palace.

“How many times can your Weak Water Sinking Abyss Formation make the water heavier?”

Su Mu asked thoughtfully.

This formation is somewhat similar to the gravity field of the Xuanhuang Zhenyue Tower. If he enters it, in case Han Jieren has bad intentions, Su Mu must at least be prepared.

But then again.

If Han Jieren really had evil intentions, Su Mu would have no psychological burden and could directly suppress Han Jieren.

If Han Jieren thought that this Weak Water Abyss Formation could suppress Su Mu, then he was probably wrong.

Su Mu didn’t dare to talk about other formations, but he was really not afraid of this Weak Water Abyss Formation.

In order to practice the Eight-Nine Mysterious Skills, Su Mu lived under the gravity field of the Xuanhuang Zhenyue Tower for several months.

Even with dozens of times the gravity, Su Mu can still move freely.

“We are now at the bottom of the sea, so the power of the Weak Water Abyss Formation will be increased, probably up to 200 times.”

Han Jieren said, “That is to say, in the formation, a drop of water will be two hundred times heavier than usual.

Of course, this is an extreme state. As time goes by, the power of the formation will continue to weaken.

With my strength, the two hundred times effect can probably last for half an hour. After half an hour, the effect of the formation will rapidly decline.

So Lord Su, you’d better finish the battle within half an hour.”

Two hundred times…

Su Mu pondered in his heart.

The two hundred times weight bonus was still within his tolerance.

You can give it a try.

“Okay, I’ll give it a try then.”

Su Mu pondered for a moment, then slowly said, “If I have the help of the formation, I am still no match for it. Then we can give up and go back to get some help to fight again.”

“I believe you can do it, Master Su.”

Han Jieren said seriously, “This monster is at most level six. If it was level seven, it wouldn’t have to hide under the ancient shipwreck, and the two of us wouldn’t have been able to escape from the ancient shipwreck just now.”

“Master Han, you may have few opportunities to interact with monsters.

The cunningness of monsters is often much more exaggerated than we imagine. We in the Taiping Division have frequent contact with monsters, and I have seen this situation too many times.

Therefore, we should never take it lightly at any time.”

Su Mu said.

“Been taught a lesson.”

Han Jieren nodded and said, “Master Su, please take action.”

Before he finished speaking, Han Jieren made a hand gesture with both hands and shouted, “Rise!”

I saw beams of light suddenly shot out from the place where Han Jieren had buried something just now.

Those light pillars rushed up more than ten feet, then exploded and connected into a curtain of light, just covering the ancient shipwreck.

Within the light curtain, the sea water began to churn violently.

Then a muddy yellow smell appeared out of nowhere and mixed with the sea water, and the sea water suddenly became heavy.

Su Mu looked at it in amazement.

Although both have the word “formation” in their names, this formation has a different kind of mystery compared to the military formation.

Su Mu put the token given to him by Han Jieren on his waist, then took a step forward and directly entered the Weak Water Abyss Formation.

Han Jieren’s eyes flickered, then his eyelids drooped slightly, and he changed the spells with his hands and continued to control the formation.

Seen from the outside, the Weak Water Abyss Formation was already a muddy yellow, and it was almost impossible to see what was going on inside.

But as soon as Su Mu entered the formation, he felt like he had entered another world.

Although there is still muddy yellow sea water around, at least you can see the scene not far away.

I saw a huge octopus emerging from the mud on the seabed and directly lifted up the sunken ship.

Its movements were very slow, as if it was carrying a mountain on its back.

The octopus’s two tentacles bound the shipwreck tightly above its head, as if it was reluctant to let it go, and as if it was protecting the shipwreck.

Its pair of copper bell-like eyes stared straight at Su Mu, its eyes full of anger.

Swish!
Several tentacles lashed towards Su Mu like whips.

The sea water, which was two hundred times heavier, was rolled over by the tentacles, but they also slowed down the tentacles.

The speed at which the tentacles attacked became extremely slow in Su Mu’s eyes.

Feeling the power emanating from the token on his waist, Su Mu indeed felt that the surrounding sea water was no different from before, and the formation had no effect on him.

Han Jieren’s methods are indeed somewhat mysterious.

Su Mu said to himself, raised his hand, and grabbed a tentacle with a snap.

“Come here.”

Su Mu shouted softly and exerted force on his hands.

The violent force directly swung the tentacles up.

The huge octopus was also swung around and slammed heavily onto the seabed.

The octopus let out a sharp roar, twisted its body, and turned the sunken ship around, holding it up, while its body slammed heavily into the mud on the seabed, causing visible deformation. (End of this chapter)
