You went on a blind date and presented an A-level wanted criminal as a meeting gift?

The engineer looked down and initially didn't notice anything unusual.

Twenty centimeters thick special steel plate, extremely sturdy, how could there be a problem?

He even stomped on it twice, but the sound was still a dull, heavy metallic echo.

"Stop playing tricks on me! Are you trying to scam me?"

The engineer sneered, but his hand holding the detonator was unconsciously sweating.

He no longer understood Lin Chen, but he always felt that this man never spoke without a reason.

Lin Chen took a drag of his cigarette and said calmly.

Do you know what the strongest acid in the world is? It's not sulfuric acid, nor aqua regia, but fluoroantimony.

"The corrosiveness of this super acid is twenty million times that of pure sulfuric acid."

The engineer's expression changed drastically. As a science student, he had certainly heard of the terrifying reputation of fluoroantimonic acid.

Lin Chen continued to explain the science in a leisurely manner.

"Jiang Tingxue, who is also the chief forensic doctor of our police station, is not only an expert in anatomy, but also a top-notch chemistry genius."

"She prepared ten liters of special compound acid solution for me overnight, which included a high concentration of fluoroantimony."

"Just now, on my way upstairs, I went to the 39th floor."

Lin Chen pointed directly below.

"That is, directly below your invincible safe house."

"I used a high-pressure spray gun to spray all ten liters of acid onto your bottom load-bearing steel plate."

The words had barely left his mouth!

The engineer suddenly heard a hissing sound coming from beneath his feet.

He looked down in terror and saw that strange white smoke was beginning to rise from the originally smooth surface of the steel plate!

Immediately afterwards, the steel plate turned black at a visible speed, and the surface began to bubble and peel off, as if it had contracted some terrible skin disease.

"This...this is impossible!"

The engineer was so frightened that he backed away and fell down on the boss's chair.

His prized special steel plates quickly became as thin as paper under the terrifying corrosion of antimony fluorocarbons.

The pungent chemical gas seeped into the safe house through the cracks, choking him and causing him to cough repeatedly and tear up.

"You're insane! You actually used something like that!"

The engineer finally broke down; his proud architectural defenses proved utterly ineffective against pure chemical destruction.

He suddenly raised the detonator in his hand, his face contorted in a grotesque roar.

"Since the base plate is ruined, we'll all die together! I'm detonating C4! Let's all go to hell together!"

Just as his thumb was about to press the red button at the critical moment!

Lin Chen moved.

He casually flicked the cigarette butt away from his hand, his eyes instantly turning icy cold.

[God-level Physics Mastery] and [Grandmaster-level Combat Mastery] erupt simultaneously!

Lin Chen spotted a load-bearing wall next to the blast door, where the stress point was precisely the stress concentration point of the entire steel fortress's base structure.

In the perfect calculations of physics, that is a fatal flaw that could affect the whole situation if one thing is done!

He suddenly sprinted forward two steps, using his waist to generate power, and his right leg, like a cannonball, kicked the wall hard with a terrifying whooshing sound!

"boom--!!!"

The force of that kick was astonishing; the entire building seemed to tremble.

The massive shockwave traveled along the walls and instantly reached the bottom of the steel fortress.

The bottom steel plate, already riddled with holes and as thin as a cicada's wing from corrosion by the super acid, could no longer withstand the terrifying shock!

"Snap! Splash!"

With a piercing sound of metal shattering, the steel plate beneath the engineer's feet collapsed instantly, creating a hole more than two meters in diameter!

"ah--!!!"

The engineer let out an extremely agonizing scream as he, along with his chair and part of the control panel, fell through the hole on the fortieth floor!

The weightlessness of freefall left his mind blank, with the wind whistling in his ears.

"Bang!"

A muffled, loud bang exploded on the thirty-ninth floor.

The engineer slammed his fist down on the 39th floor of solid concrete.

The immense impact instantly shattered his kneecaps and shinbones, the stark white bone fragments piercing through his trouser legs and exposing them to the air, while blood instantly stained the grayish-white ground.

The red detonator he was holding tightly slipped from his grasp under the violent impact, sliding a long distance across the ground before crashing into a corner and breaking into several pieces.

Everything happened too fast; from Lin Chen kicking the wall to the engineer falling from the building, it only took two seconds.

The crisis has been completely resolved.

Lin Chen stood at the edge of the hole on the fortieth floor, looking down at the engineer lying in a pool of blood on the thirty-ninth floor, groaning in pain. A cold smile curled at the corner of his mouth.

"It seems your mechanics calculations are still inadequate. If the foundation is unstable, the building will collapse."

Lin Chen clapped his hands, his tone relaxed.
