Chapter 351 Establishment of the Earth's Security Line

"Beep... Alert lifted. Spiritual pressure across the entire area is stable. Spatial curvature anchoring error: zero."

Seven hundred meters underground in Kyoto, in the joint control room.

The ultra-high frequency alarm that had been roaring for five days finally emitted its last, lifeless electronic sound and fell completely silent.

Inside the massive underground bunker, there was a deathly silence. The only sounds were the dripping of condensation from the main server rack and the heavy, labored breathing of hundreds of workers.

Clang.

It's unclear who slammed a titanium steel wrench onto the metal chassis; the crisp sound was like the flipping of some kind of switch.

"call--"

Lin Feng slumped in the chair like a lump of mud, his hands trembling as he took off his glasses, which were covered in oil and fingerprints, and wiped them haphazardly with the hem of his wrinkled shirt. He tilted his head back, looking at the explosion-proof light on the ceiling, and let out a breathy sound that sounded like a cry mixed with laughter.

Wang Mingyuan didn't sit down. He grabbed the enamel mug on the table, which had gone cold, and gulped down the bitter tea until he had chewed up and swallowed the tea leaves. Then he slammed the mug down on the table.

"Lin Feng, report the data." Wang Mingyuan's voice was hoarse, like two pieces of sandpaper rubbing together, but his back was ramrod straight.

Lin Feng hurriedly put on his glasses, tapped a few keys on the keyboard, and brought up the latest global monitoring panel.

"The Nine Cauldrons Array has been completely integrated into the earth's veins. Currently, the barrier covers the stratosphere, 20,000 meters above the surface. This is not just a light barrier, Professor Wang..."

Lin Feng swallowed hard, staring at the extremely detailed bluish-gray defense model on the screen.

"The grand formation drew upon the Earth's core's gravitational field and extreme yang energy, creating a tangible [spatial locking layer] around the Earth. Its thickness is equivalent to three thousand meters of solid star iron armor. Not only does it protect against physical impacts, it also...locks down this three-dimensional space where Earth is located."

"What is the penetration rate of High Dimension Vision?" Wang Mingyuan pressed.

"Zero." Lin Feng suddenly raised his head, his eyes blazing with fanaticism. "As long as the Nine Cauldrons' earth veins remain intact, the Void Monsters' rule corruption and spiritual infiltration will absolutely be unable to get in!"

Wang Mingyuan's jawline, which had been taut for five days, finally relaxed at this moment.

The safety line has been established.

"Switch the camera to the ground," Wang Mingyuan said.

The large screen flickered and displayed street surveillance footage of the new Chang'an City.

It was early morning.

The sky, which had been gray and gloomy due to the overloaded operation of heavy industry, now presented an extremely strange sight.

The sunlight penetrated the bluish-gray barrier of the stratosphere, filtering out all the glaring ultraviolet rays and radiation. The light that fell on the steel jungle of the city had a cold, hard texture, similar to a shatterproof glass filter.

On the streets, civilians and reserve workers who had taken shelter in underground bunkers because of the air raid sirens were gradually taking to the streets.

They looked up and stared blankly at the sky.

High in the sky, one can faintly see enormous, hexagonal, bluish-gray array patterns slowly flowing and disappearing in the clouds, as if the earth were wearing a thick layer of chainmail.

An elderly worker in overalls stood in the middle of the street, gazing at the metallic barrier in the sky, his fingers trembling slightly as he held a cheap cigarette. He took a deep drag, coughed twice, then grinned.

"This shell... looks damn sturdy."

……

Kunlun, the Valley of Death.

The gale and lightning have completely dissipated.

At the bottom of the sinkhole, the No. 9 cauldron, thousands of meters tall and entirely dark black, stands silently like an ancient sacred mountain. The array patterns on its surface, "welded shut" by lightning and fire, are breathing in and out the earth's spiritual energy at an extremely gentle frequency.

"One, two, three! Go!"

At the edge of the pit, dozens of engineering mechs were working together to drag away the wreckage of equipment that had been destroyed during the extreme sun rampage.

Zhao Yi leaned against the tracks of a mech, holding a box of self-heating military rations in his hands, shoveling mouthfuls of rice mixed with snow water into his mouth. The sleeve of his combat uniform on his one arm was torn, revealing the muscles wrapped in bandages underneath.

"Instructor Zhao, where is the Dao Master?" An engineering soldier walked over carrying two buckets of high-pressure coolant, looking around.

"They left a long time ago." Zhao Yi swallowed the food in his mouth, wiped his mouth with the back of his hand, and said, "Once the formation is closed, they will return to the Heavenly Palace on the Cloud Top."

He raised his head and looked at the enormous steel cauldron, his eyes filled with complex emotions.

……

380,000 kilometers away.

Guanghan Base, the logistics dispatch center on the second underground floor.

"Buzz—! Buzz—! Buzz—!"

After several hours of silence, the inter-star teleportation array suddenly burst into an extremely dazzling white light, and the spatial stabilization anchor of the entire underground base emitted a deep rumble.

Wearing earmuffs, Ma Cheng stood at the edge of the teleportation array, watching the massive metal containers gradually appear in the white light. Excitedly, he punched the steel pillar next to him.

"It's working! The power supply pipes at home are back connected!"

Ma Cheng yelled at the top of his lungs into the comms: "Engineering team! Unload! Smash the crates open!"

"Click! Click!"

The hydraulic shears roughly cut through the physical lock.

The heavy doors of the container crashed down. Inside, tens of thousands of brand-new weapons, their blades gleaming with a cold, eerie blue light, were neatly stacked. On the other side, explosion-proof containers were filled with the highest purity anode extract and spare fuel rods for the exoskeleton reactor.

A two-kilometer vacuum defense line.

Chen Ge was still hovering in that space ravaged by the black tide. His right arm hung limply at his sides, and the armor on his mecha's chest was pitted and cratered, like a piece of chewed gum.

"drop--"

Suddenly, a private encrypted channel from Earth's Supreme Command was connected inside the tactical helmet.

Wang Mingyuan's hoarse voice rang in the ears of the five hundred surviving defense army cultivators.

"This is the Kyoto Joint Control Room."

"The Nine Cauldrons have been placed. The Nine Provinces Barrier is now officially closed."

"Tell all the soldiers of the defense force that the home planet is safe."

A deathly silence fell over the defensive line.

Upon hearing this, a Foundation Establishment recruit who had lost his left leg and was barely maintaining his balance with the help of thrusters suddenly turned off the microphone on his communicator and burst into tears inside his cramped helmet.

No one laughed at him.

In this hellish war of attrition that lasted for several hours, what kept them from retreating even a single step was the unsuspecting blue planet behind them.

Now, the planet is armored.

"call……"

Chen Ge exhaled a long breath of foul air, tinged with the smell of blood, and the taut string in his eyes, which had been on the verge of snapping, finally relaxed.

But then, an even more violent and pure killing intent rose from the bodies of these battle-hardened survivors.

We fought to the death in the past because there was no way to retreat.

Now, they have no more worries.

"Captain Chen! The supplies have arrived!"

Below, dozens of small anti-gravity transport boats spewed exhaust flames as they pushed crates of brand-new weapons and fuel directly onto the defensive line.

Chen Ge pulled out the broken sword from the back of the mecha, which was already chipped like a saw blade, and casually threw it into the deep space.

He manipulated his intact left arm and pulled a brand-new Star Iron Ship-Slaying Blade from the transport ship.

"Click".

The array pattern connector on the hilt fit perfectly with the mecha's true energy output end, and the Extreme Yang Remnant Flame instantly ignited a three-foot-high golden flame on the blade.

Chen Ge slowly turned around, pointing the blade at the deep, silent black gate of the Aitken Basin below.

Following the siphon, a disturbingly thick shadow began to surge again from the depths of that black door. It was the main force of the higher-dimensional void, brewing a new, violent counterattack after sensing the anomalies on Earth.

"Brothers, let's change clothes."
