High-level martial arts: Contract cashback, invincible starting from the Zerg.

When we arrived at the overflow outlet pipe.

Chen Feng and Xuri Dongcuo frowned as they looked at the pipes that were filled with a pungent odor.

"Will you go first or should I go first?" Chen Feng asked calmly.

"You go first. You're tough and can withstand more attacks, and I'm better suited for sneak attacks," Xu Ri Dong Cuo chuckled.

"Alright."

As soon as he finished speaking, Chen Feng summoned the Bronze Demon-Slaying Armor.

The Bronze Demon-Slaying Armor, although it is the entry-level armor for demon slayers, is characterized by its exceptionally high elemental resistance to elements such as pollution and corrosion.

Especially against continuous elemental damage from radioactive waste liquid, its protective capabilities far surpass those of silver and gold magic armor, possessing dozens of times the protective capabilities of ordinary armor of the same tier.

Even in the environment of the TN71 base's wastegate, it cannot be melted through in a short time.

As Rising Sun Winter also donned the bronze demon-slaying armor.

The wastewater outlet pipe was even narrower than the one marked on the AI's blueprints. Its inner diameter was barely enough for one person to pass through, and there was no flat place to step on. Instead, there was only dark green corrosive waste liquid that went above the ankles, as thick as melted asphalt.

With each step, a sticky, squelching sound was produced.

The moment Chen Feng crouched down and stepped into the spillway!

A wave of heat carrying a sour, rotten smell rushed over, and a stream of corrosive liquid flowed down from the pipe above, hitting the shoulder armor directly.

Sizzle sizzle sizzle—!

The ear-piercing sound of corrosion exploded instantly in the sealed pipe, like a red-hot iron block being plunged into ice water, and white mist rose up along the bronze demon-resistant armor plates.

Chen Feng also felt a distinct heat coming from his shoulder.

Looking at the bronze armor plate that had slid down with the corrosive liquid, a shallow crater was left.

Chen Feng immediately began to activate the Vajra Core, using the demon-suppressing energy to continuously repair the demon-suppressing armor on his body.

"Good heavens, this thing is much more ruthless than the intelligence reports." Xu Ri Dong Cuo's voice came from behind, his usual playful smile had faded, leaving only a tense, hoarse tone.

Clearly, seeing the intensity of the waste liquid, Xu Ri Dong Cuo was not in a good mood either.

Chen Feng didn't respond, but instead placed his hands, clad in the Demon-Slaying Armor, on the pipe, testing the rate at which the energy was being consumed.

"Three, five, ten."

Chen Feng maintained the same posture throughout, his hands constantly and rapidly tracing the corrosive liquid on the pipe wall, letting the deadly acidic liquid rise into fine white mist on the armor plates.

It took a while before he released his hands from the tube wall.

"If I rely on the repair speed of my Vajra Core, it will consume 15% of the Demon-Suppressing Energy every minute."

"So we can only slide down directly?" asked Xu Ri Dong Cuo.

"If the vehicle is moving at high speed, the frequency of contact will double, and the wear and tear will skyrocket to 25% per minute..."

Chen Feng paused, his mind already rapidly processing the deductions, and added, "The concentration of corrosive elements inside the pipe is not constant. The deeper you go, the higher the concentration becomes, and the rate of energy loss will only increase, not decrease."

The last trace of relaxation on Xu Ri Dong Cuo's face vanished completely. He followed Chen Feng's example and reached out to press his hand against the tube wall beside him. However, he quickly withdrew his hand after only two breaths, looking at the dense pockmarks that had been etched onto his fingertip nail plate.

"Damn, is this waste liquid that toxic?"

"We need to switch to other suits the moment we exit the pipe," Chen Feng explained.

"Alright, luckily I made a contract with a demon royal, otherwise it would have been really troublesome."

"Then I'll be leaving first."

As soon as he finished speaking, Chen Feng crouched down and stepped forward, his feet sinking into the viscous waste liquid. The hissing sound of the armor plates blocking the corrosion continued, but it couldn't hurt Chen Feng at all.

Chen Feng lowered his posture to the lowest point, his back almost touching the rusted tube wall, and then pressed the bright blue Starry Sky Demon-Suppressing Energy tightly against the area of ​​intense friction on his back.

Protected by the magic of the stars.

Chen Feng not only used every bit of demon-controlling energy wisely, but also managed to keep the energy loss during high-speed movement below the red line of 20% per minute.

The next moment, Chen Feng slid down the pipe below at an extremely fast speed.

Sizzle sizzle sizzle—!

A deafening corrosive sound instantly filled the narrow pipe, and the highly concentrated corrosive liquid slammed onto Chen Feng's Demon-Slaying Armor, the rising white mist instantly enveloping the two of them.

The amount of demon-controlling energy inside Chen Feng's Vajra Core plummeted like it was falling off a cliff, dropping by a full eight percent in just over ten seconds!

The pipeline is only 800 meters long.

The two were forced to increase their movement speed to the limit.

Even with the protection of bronze armor, the two's demon-resistant armor plates were already covered with dense, corroded pits.

"Three hundred meters to the exit!" Chen Feng shouted in a deep voice. "Hold on!"

Just as Chen Feng was about to slide out of the diversion outlet pipe, he suddenly felt a pang of heart palpitation, as if he felt like he was being targeted.

Unbeknownst to the two, outside the diversion outlet pipe, three cold, shadowy lines were moving along their sliding trajectory.

These lines of energy are extremely subtle, and ordinary experts simply cannot detect them!

It turned out that the three Darkin snipers had already calculated their speed and trajectory as they slid down, and even predicted their position and timing when they rushed out of the pipe with perfect accuracy!

Just as Chen Feng was about to jump out of the diversion outlet pipe.

Three crimson armor-piercing bullets, imbued with the annihilation power of the Darkin, and carrying immense spiraling energy, hurtled precisely toward Chen Feng's visor!

Wherever the sniper bullet passed, even the polluting particles in the air were instantly vaporized.

Even the continuous hissing and corrosive sounds from Chen Feng were completely suppressed by the booming sound of this shot.

Chen Feng's pupils instantly shrank to the size of pinpoints, and his battle instincts, honed through countless trials, reacted immediately!

Zerg War Shield!!

clang--!!!

A deafening clang of metal exploding instantly rang out, the sound even reaching the ears of Wu Yingguang and the others...

The crimson Darkin Annihilation Bomb struck the Zerg Shield, right in front of the Darkin's exclusive Annihilation Bomb.

The Zerg Hunter's Shield, obtained from the Whitefly Zerg, was instantly torn apart! Three sniper bullets, their bodies glowing red, pierced the Whitefly Zerg's shield with devastating force!

"Damn it!" Chen Feng quickly activated Chidori Thunder Beast, greatly increasing his movement speed.

That's how he managed to dodge the three deadly sniper bullets!
