139: Chapter 139 Breaking the Dragon Stone

Hum—!!!

A piercing, high-frequency screech, seemingly capable of tearing through one's eardrums, suddenly erupted from deep within the twelve Iron Corpses' fists!

A visible, translucent shockwave, like a layer of distorted air film, tightly enveloped their dark golden iron fists.

There was no magical light, only the pure roar of machinery.

Bang! Bang! Bang! Bang!

Twelve pairs of iron fists, rippling with shockwaves, struck the 800mm-thick titanium-carbon blast door like a violent storm!

There was no deafening explosion; instead, there was a teeth-grinding sound of physical grinding and tearing.

Szzzt! Szzzt! Szzzt!

Gu Shen stood in the back, calmly watching it all.

He clearly saw that the "Dragon Stone," which not even a Heaven Lightning Talisman could shake, was beginning to undergo terrifying physical changes under the Iron Corpses' high-frequency vibrating fists.

With every punch that landed.

The indestructible titanium-carbon alloy on the surface of the blast door crumbled at the molecular level, turning into fine metal powder that fell away.

Immediately after.

The extremely high-frequency physical friction generated terrifying localized heat in a very short time.

The color of the center area where the blast door was struck began to change drastically.

It went from dark gray to dark red, then to a glaring cherry red, and finally to a dazzling bright white!

Under the pounding of physical limits, the hard metal began to melt.

Large drops of scalding molten iron, mixed with burning polymer energy-absorbing gel, dripped from the door like magma, smashing charred holes into the ground.

A pungent, acrid smell of burnt metal instantly filled the entire corridor.

"Thirty seconds! Metal fatigue has reached the critical threshold!" Crab counted down precisely.

Crack!

A dull sound of metal tearing finally came from the center of the blast door.

The internal structure of the door, capable of withstanding a nuclear blast, was forcibly snapped. A two-foot-deep, glowing red, molten crater appeared on the door.

"Break."

Gu Shen's eyes narrowed.

Boom—!!!

The twelve Iron Corpses retracted their fists in perfect unison, their internal micro-batteries instantly pushing output power to the max. The twelve iron fists, carrying terrifying, unstoppable kinetic energy, simultaneously smashed into the center of the molten crater!

The loud noise shook the heavens.

The 800mm-thick polymer blast door was finally completely penetrated!

The massive door shattered into pieces, turning into countless heavy metal chunks glowing with dark red residual heat, collapsing into the corridor and kicking up a cloud of pungent dust.

A wide, gloomy corridor entrance was completely exposed before Gu Shen's eyes.

Whoosh—

Along with the shattering of the door, an abnormally pungent cold wind, mixed with the smell of formaldehyde preservative and the stench of some unknown biological rot, surged out from behind the door.

Due to the pressure imbalance between the two ends, this airflow even formed a weak whirlwind at the entrance.

Gu Shen did not enter immediately.

He stood very cautiously at the edge of the glowing red metal fragments, letting the pungent cold wind blow against his gray robe, his gaze piercing through the rising dust as he looked coldly into the interior of the door.

4th Floor Above Ground. Biochemical Laboratory.

His gaze pierced through the gloom.

What appeared before Gu Shen was an extremely vast circular metal hall. Its area was several times larger than the underground Shelter plaza.

The hall's dome was extremely high, embedded with countless long-extinguished exhaust pipes covered in spiderwebs.

And in the center of this hall.

There was no Pill Furnace from the Cultivation World's Pill Refining Room, nor were there any Jade Slip racks for storing classics.

Instead, there were hundreds of extremely large, cylindrical glass containers, each over two people tall!

These containers were densely packed, like an eerie forest made of glass, extending to the end of his vision.

Inside, the containers were filled with a turbid, viscous, pale green liquid.

Through those liquids.

Gu Shen clearly saw that inside every glass cylinder, a strange, nauseating creature was submerged.

Some had human bodies and beast heads; some had three thick arms; some had their chests completely cut open, stuffed with rusty metal gears; even worse, half of some heads had been replaced with cold machinery bristling with black pipelines!

These pipelines were like twisted blood vessels, connecting to the heavy metal bases at the bottom of the containers.

"Is this the 'Ascension Project' that Shelter No. 7 conducted back then? Forcibly stitching flesh and metal together..."

Gu Shen looked at this scene, a trace of extreme coldness flashing in his eyes.

Just at this moment.

"My Lord! Warning!"

Crab's electronic voice rang out in Gu Shen's ears very urgently.

"Because the door was breached, the constant air pressure inside the 4th Floor Above Ground has been compromised! External air is rushing in, causing the physical boiling point of the life-sustaining nutrient solution in those glass containers to drop rapidly!"

Gurgle!

As if to confirm Crab's warning.

In the hall, within the dozens of glass containers closest to the entrance, the green nutrient solution, which had been dead silent for hundreds of years, suddenly began to churn violently.

Large clusters of bubbles surged from the bottom of the containers, rising frantically.

Crack.

A sound of glass cracking, extremely faint yet clearly audible in the deathly silent hall, suddenly rang out.

Gu Shen's gaze swept over like a blade.

Ten zhang away to the left. A crack appeared on the surface of a container holding a humanoid monster whose right arm had been replaced with a rusty chainsaw.

That Aberration, which had slept in the nutrient solution for who knows how many years.

Very slowly, and extremely stiffly.

Opened its dead fish eyes, which had no pupils and were only a turbid, pale white.

An abnormally violent, bloodthirsty, primal killing intent.

On the 4th Floor Above Ground of the Wasteland, it suddenly awakened.
