160: Chapter 160 The Sixth Underground Level

The pale white fire of rules flashed and vanished in the void.

As the cross-world teleportation ended, Gu Shen's feet landed firmly on the hard refined iron floor.

The air around him was filled with the sour, acrid scent of evaporated preservative fluid.

4th Floor Above Ground, biochemical machine room.

The remaining water on the ground had dried up, leaving behind a layer of grayish-white scale.

A patch of green fungus had grown over the fragments of the broken biochemical tanks.

Time flowed synchronously between the two worlds.

The passage of time had left objective physical traces in this isolated underground palace.

The black iron clasp at Gu Shen's collar flashed with a faint blue light, and the mechanical spider extended its probe.

It connected itself to an undamaged data port on the wall.

"My Lord, the offline log comparison is complete." The Crab's electronic voice echoed softly in the spacious machine room, conveying the precision of data processing. "The physical state of the 4th Floor Above Ground ecological zone is stable; no mutant creature activity has been detected. The master control signal from the Thirteenth Underground Level has attempted several high-frequency probes, but since the physical network was severed by you, the other party has failed to intrude into this floor's local area network."

Gu Shen nodded slightly and waved his large sleeve.

Twelve damaged Cyber Iron Guards lined up in the center of the machine room.

During the close-quarters battle against the Sea-Covering Black Flood Dragon in the Yunmeng Great Swamp, these Iron Guards had endured tremendous loads.

The chests of the No. 3 Iron Guard, Iron Guard No. 7, and No. 9 Iron Guard were largely caved in, and their internal Sea-Splitting Profound Whale skeletons were covered in fine cracks; with the slightest movement, the exposed joint bearings emitted a clicking sound.

Gu Shen's Divine Sense swept across his Storage Ring, and three massive beast skeletons landed on the floor one after another.

The Flame Poison Crocodile King, Golden-Horned Rhinoceros Beast, and Thunder Cloud Snow Leopard.

Even after many years, the skeletons of these Tier 3 Great Demons still radiated an intimidating, heavy pressure.

The surfaces of the skeletons naturally possessed demon patterns that resisted Spells.

"The equipment here is severely damaged. We are going to the 6th Underground Level."

Gu Shen put away the demon bones and led the Iron Guard legion toward the underground of the Spiritless Ruins.

Following the slag discharge shaft, Gu Shen and the Iron Guard legion slid all the way down.

Rust from the walls on both sides fell off in succession, and dull metallic echoes reverberated through the shaft.

The sound of landing echoed.

6th Underground Level, military manufacturing zone.

The ground was covered in the wreckage of heavy riot robots left over from the last battle.

The massive assembly line machine tools lay like dead steel beasts, silently dormant in the vast, dark hall.

"Crab, take over the independent control network of this area."

The mechanical spider leaped from Gu Shen's shoulder, its eight probe claws piercing into the data interface of the master control console.

A waterfall of blue code refreshed rapidly on the dust-covered screen.

"Command confirmed. My Lord, I am searching for activatable heavy stamping machine tools and alloy smelting furnaces, but the Thirteenth Floor's The Mainframe has cut off the main power grid. The machine tools' servo motors lack external energy injection and are in a physically locked state."

Gu Shen walked toward the alloy smelting furnace that stood ten zhang tall.

He took out twelve Low-Grade Spirit Stones from his Storage Ring and flicked his fingers repeatedly.

Amidst the whistling wind, the Spirit Stones were precisely embedded into the key nodes of the machine tool's various power distribution boxes and hydraulic hubs.

The AI Crystal at the center of his brow pulsed at a high frequency.

Gu Shen pointed his fingers like a sword, forcing out Geng Metal Sword Qi, which moved rapidly across the machine tool's heavy metal surface.

Stone chips flew everywhere.

A composite Formation pattern of the Cultivation World's Spirit Gathering Formation and One-Qi Formation, magnified dozens of times, was forcibly carved onto the surface of the Wasteland heavy industrial machinery.

The Formation took shape.

The pure Spiritual Qi contained within the Spirit Stones was forcibly converted by the Formation pattern into high-pressure kinetic energy, pushing it into the stalled motors.

Boom!

The smelting furnace seemed to emit a dull roar, and orange-red high-temperature flames surged within the furnace chamber.

The heavy stamping machine emitted a rhythmic metallic clanking sound, and the entire military assembly line, forcibly driven by the metaphysics of the Cultivation World, underwent a partial revival.

Gu Shen issued his commands, and the nine intact Iron Guards acted as the most precise porters.

They continuously moved the "titanium-tungsten military alloy plates" and "high-conductivity superconducting cables" piled up in the armory warehouse.

The Cultivation World's hundred-refined fine iron and refined red copper had already been traded away at the Wanxiang Merchant Alliance, so Gu Shen used Materials on hand, completing a substitute with the Wasteland's top-tier military Materials.

"Remove the damaged skeletons and implant the Tier 3 demon bones."

Gu Shen stood before the three heavily damaged Iron Guards, holding his saber.

The blade cut along the gaps in the machine body, stripping away the deformed armor and the crack-filled Sea-Splitting Profound Whale skeleton.

He took the thick leg bone of the Flame Poison Crocodile King, and with the gold-severing saber imbued with Thunder-Magnetic Force, he cut and shaped it to fit the dimensions of human arm and chest bones.

The Soul-Pulling Threads transformed into a delicate scalpel, carving energy conduction grooves onto the surface of the Crocodile King bone.

The Wasteland's superconducting cables were precisely embedded into the grooves, acting as physical meridians to transmit the kinetic energy of the miniature batteries.

Gu Shen poured out a jade bottle, dripping the remaining high-purity mutant bone marrow onto the joints where the bearings and demon bones connected.

This life-force mucus, which carried radioactive properties, erupted with an extremely strong assimilation force, welding the metal and bones together tightly.

The Golden-Horned Rhinoceros Beast's chest bone protected the Iron Guard No. 7's nuclear battery, while the Thunder Cloud Snow Leopard's spine granted the No. 3 Iron Guard extremely high torso flexibility.

The internal framework reconstruction was complete.

Molten red titanium-tungsten alloy was poured along the conduction grooves into cooling molds.

The heavy stamping machine fell like Thor's hammer, pressing thick armor plates into shape.

"Armor up."

The freshly forged titanium-tungsten alloy armor, still retaining its dark red residual heat, was firmly fixed onto the bodies of the twelve Iron Guards with extremely sturdy industrial rivets.

Mica spirit sand from the Cultivation World was sprinkled onto the joints, smoothing out the last bit of friction in the mechanical transmission.

Three hours later.

The roaring of the machine tools slowly ceased, and the furnace flames dimmed.

Twelve brand-new Cyber Iron Guards stood in the center of the armory.

Their bodies were covered in streamlined, matte black titanium-tungsten armor, completely concealing the internal demon bones and mechanical pipelines.

The miniature fusion batteries in their left ventricles emitted a faint, eerie blue light through the gaps in the armor.

Three of these Iron Guards were more burly, and the foundation of the Tier 3 demon bones allowed them to exude a heavy sense of physical oppression even in silence.

Gu Shen drew the thunder pattern gold-slaying blade. The blade carried no magical power as he backhandedly struck the chest of the Iron Guard modified with the Golden-Horned Rhinoceros Beast skeleton.

"Clang."

A dull thud echoed.

The blade was deflected by a powerful rebounding force.

Only a shallow white mark remained on the titanium-tungsten alloy armor; the Tier 3 demon bone inside was completely unharmed.

"The outer titanium-tungsten armor resists physical kinetic energy, while the inner demon bone insulates against Spiritual Qi and provides immunity to Spells. The miniature batteries provide overload output."

Gu Shen sheathed his blade, his deep gaze sweeping over this brand-new heavy armored legion.

Such a product of inter-world fusion had already surpassed the category of ordinary Foundation Establishment Puppets.

He turned around and looked toward the end of the Sixth Level hall, at the massive cargo gate that led to the depths of the underground.
