64: Chapter 63 Fortress Upgrade

The ice wall could only hold it back for three seconds.

"Close the door."

Taking advantage of the moment the ice wall provided, Lin Feng's figure was like a bolt of lightning as he retreated back into the train car.

His slender fingers pressed down hard on the close button of the center console.

"Clang—Click!"

The heavy, dark silver armored side door locked tight with a perfect seal just a second before the Spider Queen shattered the ice wall and lunged forward with her sharp claws.

"Clang! Clang! Clang!"

Sharp claws frantically slashed at the train's external armor, creating a tooth-gritting sound of metal grinding.

Concentrated acid sprayed onto the train body, making a sizzling corrosion sound.

Through the bulletproof glass, one could even see the Spider Queen's crimson compound eyes and her barb-covered mouthparts pressed tightly against the glass, radiating a predatory, murderous light.

But she couldn't get in.

The defensive power of the level 2 fortress train demonstrated an absolute sense of security at this moment.

Inside the train car.

A narrow escape from death.

Su Ya and Xia Wanqiu slumped onto the floor, gasping for air in large gulps.

Looking at the furious but helpless Tier 2 peak monster outside, they felt as if a lifetime had passed.

Lin Feng took off his black trench coat, which was covered in acid, and tossed it aside.

His lean, muscular chest heaved violently a few times before his breathing returned to a steady rhythm.

He looked at the four shivering Mutated Snow Rabbits in the corner, then at the fifty barrels of [anti-corrosion alloy gel] neatly stacked in the system space.

The corners of his mouth finally curled into a cold, satisfied arc.

A bountiful harvest.

He had the foundation for farming and the materials to upgrade the armor.

This extreme escape had earned him a fortune.

But the crisis was not over.

"Beep, beep, beep!"

Dense red dots lit up on the radar screen of the center console.

Under the Spider Queen's summons, the army of hundreds of Acid Venom Spider from inside the chemical plant had flooded into the unloading area like a tide.

They completely surrounded Train No. 99, and the green venom even gathered into small puddles.

"Train Master, the armor durability is falling."

Su Ya forced herself to stand up and looked at the dashboard, her beautiful face full of worry. "The external defensive power grid is consuming too much energy."

Lin Feng's gaze slowly swept across the energy reserve bar on the dashboard, which was dropping rapidly.

Every time the defensive power grid repelled the Poison Spiders, it required a massive amount of electrical energy.

And all of that energy came from the woman being used as a 'human battery' in the bottom power room.

Lin Feng's eyes gradually became deep, like a black hole that swallowed everything.

Without the S-rank Purple Lightning's area-of-effect destructive power, they could only be trapped in this iron shell and take a passive beating.

"This power grid won't last long."

Lin Feng turned around, his combat boots making a heavy sound against the metal floor.

He didn't look at the insect tide outside again.

Instead, he walked straight toward the passage leading to the bottom power room.

"That woman has suffered enough."

Lin Feng's voice echoed in the carriage, carrying the aura of a tyrant who controlled everything.

"It's time to go claim my spoils of war."

"Clang! Clang! Clang!"

Outside the carriage, the Tier 2 peak Spider Queen's claws were still frantically slashing at the armor.

The ear-piercing sound of metal grinding, mixed with the sizzling of high-concentration acid corroding the iron plating, echoed across this wasteland shrouded in a ghastly green rain curtain.

But inside the carriage, there was the dead silence of survivors after a disaster.

Su Ya and Xia Wanqiu slumped on the cold metal floor, their chests heaving violently as they greedily breathed in the filtered clean air in large gulps.

The two Tier 1 stunning queens were currently in a state of extreme disarray.

Su Ya's white shirt, soaked with sweat and acid rain, had become a semi-transparent veil clinging tightly to her skin.

The strips of cloth torn during the battle could not hide her breathtakingly full curves at all.

Her legs were weakly crossed, and the light on her ice-blue horns was dim—a sign that her magic power was completely exhausted.

Xia Wanqiu was in even worse shape; the acid burns on her calves were still oozing blood.

The few remaining pieces of mutated beast hide on her body had mostly slipped off, leaving large patches of fair, plump, and snowy skin exposed.

That demon tail, which usually stood high and proud, now lay limp on the floor.

But their gazes, as if by prior agreement, were fixed firmly on the upright figure ahead.

Lin Feng took off his venom-stained black trench coat and tossed it into a corner.

His lean upper body was covered in a fine layer of sweat, and his muscle lines were as perfect as if carved with a chisel.

Under the dim overhead light, he radiated a suffocatingly wild male pheromone.

In this post-apocalyptic world where death could strike at any moment, being protected by such a man using absolute violence, snatching a life back from a Tier 2 peak grim reaper...

This bone-deep sense of security made the two succubi look at Lin Feng with eyes that held not just fervent worship, but also a morbid, unwavering devotion.

Lin Feng ignored the gazes behind him.

His attention was entirely focused on the fifty barrels of dark green [anti-corrosion alloy gel] in the system space.

This was the loot they had traded their lives for.

"System, open the train upgrade furnace."

Lin Feng issued a cold command in his mind.

"Hum—"

In the center of the console, a virtual furnace projection emitting a ghostly blue light slowly emerged.

Without hesitation, Lin Feng dumped the fifty barrels of gel from his spatial backpack, along with the large amount of high-grade Scrap Iron scavenged and stockpiled in the lower hold, all into the furnace.

[Beep—!]

[Upgrade materials detected: 50 units of anti-corrosion alloy gel, 3000 units of high-grade metal scrap.]

[Materials meet the conditions for deep restructuring of the train armor.]

[Initiating full upgrade program...]

As the system's mechanical voice finished.

A beam of deep blue light, so bright it was impossible to look at directly, shot up from the furnace, instantly piercing through the roof of the entire two-car Train No. 99!

"Oh my god!"

Su Ya and Xia Wanqiu instinctively raised their arms to block the intense light, their beautiful eyes filled with shock.

This blue light turned into a layer of light membrane as if it were a physical substance, like a giant cocoon, completely enveloping the tens-of-meters-long train.

A miracle was unfolding upon the ruins of the laws of physics.

The black armor, which had previously looked a bit bloated with obvious patchwork marks from absorbing the Raiders' train, began to melt and reshape like wax under the wash of blue light.

The ear-piercing sound of metal stretching rang out both inside and outside the carriage.

The internal space of the carriage was widening and lengthening at a speed visible to the naked eye.

Su Ya and Xia Wanqiu could even feel the metal floor beneath them constantly extending.

And on the outside of the carriage.

The original ordinary black armor faded away, replaced by a layer of deep, heavy, and cold dark-silver alloy armor plates that covered the train's surface layer by layer like dragon scales.

The anti-corrosion alloy gel integrated perfectly into the steel, forming an indestructible dual physical and chemical line of defense.

"Sizzle, sizzle—"

The abyssal acid rain pouring down outside hit this new layer of dark silver armor, no longer able to corrode it into that pungent white smoke; it could only slide off helplessly, unable to leave even a single white mark.

Even that furious Tier 2 peak Spider Queen, wielding claws capable of cutting through steel bars, could only produce sparks and a series of futile thuds when she slashed at the armor.
