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

The liquid column of aqua regia traced a straight path in the air, emitting corrosive vapors.

Where the liquid column passed, even the air made a "hissing" sound.

The scattered droplets that splashed onto the ground instantly corroded the cement surface, creating small pits that emitted white smoke.

If any normal person were standing here, they would most likely turn around and run away.

Lin Chen didn't run away.

He didn't even take a step back.

[God-level Danger Perception] The trajectory was locked 0.3 seconds before the liquid column was ejected, and [God-level Parkour] was activated simultaneously.

Lin Chen's body shifted horizontally by half a meter at an incredible angle.

It's half a meter.

Adding one centimeter is a waste, while losing one centimeter will lead to injury.

The pale yellow acid whistled past his clothes and hit the metal pipe behind him, instantly corroding a fist-sized hole in the pipe wall.

Fireworks sprayed wildly, and jets of aqua regia drew deadly arcs across the factory grounds.

But Lin Chen's figure was like a ghost.

He seemed to know in advance where each drop of acid would land, dodging and weaving through the dense gaps in the liquid columns with movements precise to the millimeter.

His clothes were spotless, not a drop of acid had gotten on them, and even his shoes were dry.

The fireworks lasted for a full ten seconds, but Lin Chen wasn't hurt at all.

"Stop! You stop right there!"

The fireworks roared, adjusting the nozzle angle and increasing the air pressure.

The aqua regia column grew thicker and more powerful, almost covering a three-meter-wide area in front of Lin Chen.

This time, Lin Chen did not dodge.

He took a step forward.

Heading towards that column of acidic water.

The eyeballs of the fireworks almost bulged out from behind the mask.

Is this madman going to commit suicide?

As Lin Chen moved forward, he casually picked up a titanium alloy maintenance rod that had been abandoned by the workers at his feet.

It is about 1.2 meters long, hollow, and weighs less than 3 kilograms.

He gripped the titanium alloy rod and suddenly accelerated.

He lunged forward three steps, and at the same time, the titanium alloy rod in his hand cut diagonally from bottom to top at an extremely tricky angle, directly beneath the column of aqua regia.

[God-level Physics Mastery] Entering overload operation.

In fluid mechanics, there is a classic effect called the Coanda effect, also known as the wall adhesion effect.

When a high-speed fluid comes into contact with a curved solid surface, the fluid will not bounce off directly, but will change direction along the solid surface and flow along the curved surface.

The titanium alloy rod in Lin Chen's hand has a round tube cross-section, which provides a perfect arc-shaped contact surface.

The angle, force, and speed at which he cut in were all precisely calculated by his brain.

"Hiss hiss hiss—"

The moment the aqua regia column came into contact with the surface of the titanium alloy rod, it did not splash or bounce off. Instead, it seemed as if an invisible hand had grasped its direction, and it made a sharp turn of nearly 120 degrees along the curved surface of the tube wall!

The pale yellow corrosive liquid was redirected and reflected back directly towards the fireworks!

"Varied--"

The fireworks didn't have time to react.

The rebounding jet of aqua regia sprayed precisely onto his protective suit on his chest.

"laugh--!"

Military-grade chemical protective fabric lasted less than two seconds in front of aqua regia before it began to smoke, change color, and dissolve.

"ah--!"

The fireworks emitted a heart-wrenching scream.

The pain of acid seeping into the skin through the chemical protective suit is ten thousand times more intense than any form of torture.

He threw away the sprayer like a madman and began tearing at his melting hazmat suit with his bare hands.

He staggered backward, fell, and rolled on the ground, trying to shake off the acid clinging to his body.

Lin Chen threw away the titanium alloy rod in his hand, which was riddled with holes from acid corrosion, and clapped his hands.

"Playing with fluid mechanics?"

He looked down at the wailing, rolling flames on the ground, his eyes cold and devoid of warmth.

"You dare to challenge me?"

The hazmat suit of the fireworks melted extensively, revealing the thin body underneath.

Fortunately, the amount of acid rebounding was not large, and he removed the outer layer of fabric in time, so his skin was only burned in one area and did not penetrate into the muscle.

But the pain had already caused him to lose most of his mobility.

His mask fell off as he rolled, revealing a pale, thin face that looked to be about thirty-five or thirty-six years old.

His facial features are very ordinary; he would be completely unremarkable in a crowd.

Only in those eyes, even amidst extreme pain, did a mad, twisted, and resentful light still burn.

"You...you can't...how could you change the direction of fluid with just a pipe...this violates..."

"Violate what? Violate your rudimentary basic chemistry knowledge?"

Lin Chen walked over step by step, his footsteps echoing in the empty factory area.

"The Coanda effect, a fundamental physics concept, is covered in Chapter 3 of the university-level fluid mechanics textbook."

"It has nothing to do with chemistry."

He crouched down, looking down at the face of the fireworks, distorted by pain and despair.

"Your supposedly invincible knowledge of chemistry can be disproven by me using the most basic physics. Do you know what that means?"

Flame's lips trembled violently.

Lin Chen stood up and stepped on the hand that Yan Huo reached for his waist.

He touched something—a glass capsule the size of a fingernail, hidden in his belt buckle.

Potassium cyanide.

Fireworks wanted to commit suicide.

Lin Chen stomped on the ground next to his wrist, shattering the pebbles that flew up and hit Yan Huo's face, startling him into pulling his hand back.

Lin Chen bent down, pinched the potassium cyanide capsule between two fingers, gently took it out, glanced at it on his fingertips, and then flicked it away.

"Want to die?"

"You won't die without my permission."
