Chapter 620: The new laboratory of the Root, the Hokage who is cautious in the village.
In a dark underground space, the lighting here is extremely dim.

but,

At this moment in this dark space, there are still many people conducting experiments.

All around were people lying in nutrient tanks. Their faces were as pale as paper, with despair on them. It was obvious how desperate these people were when they were unconscious.

Especially the dim light, which makes it look like some shady experiment being conducted at first glance.

This is the place that Utatane Koharu and Mitokado En found for the roots to conduct experiments.

This is also the most hidden place. As long as the people at the root do not expose themselves actively, no one can find this place.

of course,

In order to ensure the safety of this place, Danzo Shimura directly sent more than a dozen top Root jonin who were resurrected by the Impure World Reincarnation to patrol here.

I’m just afraid that something like last time will happen again.

With the top-notch jonin who have been resurrected by the Impure World Reincarnation, they are almost immortal and will fight bravely. Even if that person possesses space-time ninjutsu, he will still be a little afraid of these people.

In order to conceal this location, Sarutobi Hiruzen went home first, changed into ordinary clothes, and put on a hat!

He looks like an ordinary person, but wearing a bamboo hat will attract a lot of attention.

Sarutobi Hiruzen first left the Sarutobi clan and walked around the area under the jurisdiction of the Sarutobi Guard in the village twice, then he hid his whereabouts and went to the area where the Root Laboratory was located.

This is an open area with sewage treatment pipes underneath.

and,
The roots are now in a space that is not being used for underground wastewater treatment!

Of course, this is also the area controlled by the Tsunetsu clan.

“Stop!” Just as Sarutobi Hiruzen was about to enter from a hidden entrance, a low shout rang out.

Brush, brush, brush～～

Immediately afterwards, seven or eight people came from different corners and blocked Sarutobi Hiruzen.

These people were wearing black clothes and had a big hat brim that just covered their heads.

These people still have masks of roots on their faces!
Just like a regular Root ninja.

but,

Sarutobi Hiruzen could see some imperceptible cracks in the places where these people were not covered.

It can be concluded that

These people are the Root members who were resurrected by Danzo Shimura.

When Sarutobi Hiruzen was observing these people through his bamboo hat, the leader looked at Sarutobi Hiruzen and said, “Who are you? Why are you trespassing on private property?”

While asking questions, these people had kunai in their black-gloved hands.

As long as Sarutobi Hiruzen’s answer did not satisfy them or revealed a flaw, they would take action immediately.

Sarutobi Hiruzen will not be given the chance to resist. Of course…this is also the order of Danzo Shimura.

“It’s me!” Sarutobi Hiruzen’s face was gloomy. Although he was a little unhappy with the people who intercepted him, he still lifted his hat, revealing his old face.

Although these people did not recognize their identities, their seriousness in guarding the laboratory was still recognized by Sarutobi Hiruzen. “Third Hokage?” When they saw Sarutobi Hiruzen’s face, they were obviously stunned.

Obviously, no one expected that Sarutobi Hiruzen, the dignified Hokage, would come to the laboratory dressed like this.

“Go and check to see if he is the Hokage transformed by the transformation jutsu!” To be rigorous, the leader signaled the people next to him to go and check.

The person next to him walked up to Sarutobi Hiruzen without any hesitation and began to examine him!
As for being afraid that Sarutobi Hiruzen was in disguise? And was going to attack him? What a joke. The people who were reincarnated by the Impure World Reincarnation were originally immortal. As long as he ensured that Shimura Danzo, who was released from the Impure World Reincarnation, was not in danger of his life, they could continue to exist.

If Sarutobi Hiruzen really took action, then things would become simple and they wouldn’t have to bother monitoring him.

Sarutobi Hiruzen couldn’t help but frown as he felt these people monitoring his body rudely!

But when he thought that this was for the laboratory, he endured it.

“No problem~!” After completing the test, he went back to report.

“I’m sorry, Lord Hokage, but this is a special period now. We have to do this to prevent others from sneaking in!” After confirming, the leading Root Ninja bowed and apologized!
“Hmph,” Sarutobi Hiruzen snorted, but continued, “Can I come in now?”

“Haha… Hiruzen, why didn’t you inform me when you came here? I could have come out to pick you up in person!” As soon as the test was over, Danzo Shimura walked out of the laboratory.

Behind him, there were several people and a man in a white coat. The man in the white coat was the one he sent to monitor Danzo Shimura.

So, when the man in the white coat saw Sarutobi Hiruzen, he nodded.

Sarutobi Hiruzen looked at Danzo and continued, “Have you been here a long time ago? Are you waiting to see me make a fool of myself?”

Sarutobi Hiruzen snorted coldly. He knew Danzo’s character too well and naturally guessed what Shimura Danzo would do.

When the Root Ninja just arrived and checked his identity, Danzo Shimura must have been watching from behind, maybe… he was even laughing behind him.

“Haha…don’t be so serious!” Shimura Danzo also laughed twice to cover up his non-existent embarrassment, and then continued: “You also know that our Root has reached a critical moment now!”

“The Explosive Organization and the Uchiha clan have always coveted the Root laboratory, so we must be rigorous in everything we do!”

“This is also a last resort!”

Danzo Shimura also came up with the idea that it was for the Root Laboratory, leaving Sarutobi Hiruzen unable to refute it.

“Then how will I verify it every time I come here?” Sarutobi Hiruzen narrowed his eyes and looked at Shimura Danzo and spoke again:
“And do you need this verification when you come here?”

At this moment, there was danger in Sarutobi Hiruzen’s eyes as he looked at Shimura Danzo.

“Of course not…” Shimura Danzo was no longer embarrassed, but continued to explain: “I have engraved marks on the backs of these people who have been reincarnated. As long as I activate the marks, they will naturally know that I am real!”

Sarutobi Hiruzen was speechless: “.”

Shimura Danzo naturally saw that Sarutobi Hiruzen was speechless, and then continued: “When you carve your mark on the people who come out of your soul land, they can easily identify your identity!”

“I think you have already thought about the identities of the first batch of people to be reborn this time?”

When Shimura spoke, he glanced around and continued, “This is not the place to talk. Come in with me and let’s discuss this!”

The words fell,

He took Sarutobi Hiruzen into the dark laboratory.
