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

Yunshan Villa District, on the western outskirts of Jiangcheng.

This is the real affluent area of ​​Jiangcheng. Wang Dehai's detached villa is located in the heart of the entire villa area, covering nearly a thousand square meters, and is heavily guarded.

But at this moment, even the most stringent private security measures could not compare to the triple cordon outside the villa and the heavily armed and vigilant special police officers.

The entire villa has been completely taken over by the police.

The atmosphere was oppressive, like the deathly stillness before a storm.

Inside the villa, in the living room.

A figure stood with his hands on his hips, spitting as he directed his SWAT team.

"Hurry! Hurry! Don't miss anything with a screen, that can make sounds, or that's plugged in!"

Li Mingyu patted the dust off his hands, his face filled with barely suppressed excitement and pride.

The crushing defeat on the high seas was the biggest stain on his career.

Now, an opportunity to save face and even surpass Lin Chen is right in front of us!

He volunteered to apply to Su Qingge for the job of providing close security for the core area of ​​the villa.

In his view, that so-called sound engineer was nothing more than playing some acoustic tricks.

If we cut off all possible means for him to commit crimes, wouldn't we be like a turtle in a jar?

"Take that LCD TV apart! Yes, pry the motherboard out!"

"And that Bluetooth speaker, smash it!"

"Don't forget that old radio in the study! Even take all the batteries from the electronic doorbell!"

Eager to make a name for himself, Li Mingyu directed his men to carry out a brutal, almost invasive cleaning of the luxuriously decorated villa.

Although the SWAT team members felt the order was somewhat harsh, it was, after all, an order from their superiors, and they had no choice but to carry it out meticulously.

Soon, all the electronic devices in sight were disassembled and turned into a pile of cold parts.

"And another thing! Cut off the central power supply! Only keep the bare minimum of emergency lighting on!"

At Li Mingyu's command, the dazzling crystal chandelier inside the villa was instantly turned off.

The entire space was shrouded in a deathly silence and oppressive gloom, with only a few emergency lights in the corners emitting a pale white light.

After doing all this, Li Mingyu let out a long sigh of relief, his chin held high.

He turned around, his gaze filled with undisguised provocation and smugness, and stared straight at Lin Chen, who had been leaning against the window without saying a word the whole time.

"Consultant Lin, did you see that?"

Li Mingyu's voice was filled with barely suppressed smugness.

"That's what professionalism looks like!"

"Forget about infrasound and ultrasound; they're all paper tigers in the face of absolute physical isolation!"

"Without electronic devices as a medium, let's see how that murderer can kill! This is the wisdom of us criminal investigators—relying on logic and methods, not some vague guesswork!"

His shouting caused the surrounding police officers to look embarrassed.

Su Qingge frowned, her pretty face frosty.

Jiang Tingxue didn't even bother to look at him; her cool, clear eyes remained fixed on Lin Chen, filled with both inquiry and trust.

Lin Chen, who was publicly provoked, showed not a ripple on his face.

He looked at Li Mingyu's stupid appearance and a pity-like smile appeared on his lips.

That look was more lethal than any direct insult.

Just a second before Li Mingyu was about to explode in rage from that gaze, Lin Chen made his move.

He walked slowly to the gleaming marble coffee table in the center of the living room.

I casually picked up a Bohemian crystal glass from the food cart next to me, which contained half a glass of red wine.

"Smack."

A soft sound.

He placed the cup steadily in the center of the marble countertop.

This inexplicable action stunned everyone.

Li Mingyu scoffed.

"What's wrong, Consultant Lin? Are you planning to bolster your courage with alcohol?"

Lin Chen ignored him.

And at that very moment.

[God-level Mechanical Mastery] and [God-level Hearing] resonate instantly!

Om-!

Lin Chen's gaze seemed to instantly gain the ability to penetrate walls.

The complex central air conditioning duct system of the entire villa, with its intricate metal pipes hidden between the ceiling and walls like the veins of a giant beast, transformed into an incredibly clear and precise three-dimensional structural diagram in his eyes!

The length, diameter, bends, and even the gaps at the joints of every pipe are presented in his mind as data.

He "saw" the wind, how the airflow blowing from the main engine flowed, branched, and converged in these pipes.

Lin Chen's gaze swept over the massive system.

Then, he strolled to a main air vent in the corner of the living room.

Li Mingyu had just checked there and confirmed that it was just a regular ventilation opening.

Lin Chen stretched out his slender fingers and, amidst the puzzled gazes of the crowd, gently fiddled with the metal slats of the Venetian blinds.

His movements were slow and gentle.

Each flick adjusts the blade to an extremely small, even bizarre, angle.

That wasn't for ventilation; it was more like some kind of precise calibration.

After doing all this, Lin Chen reached back and pulled out a heavy silver chopstick used for eating Western food from the food cart.

He walked to the other wall, where there was also an access panel for a duct.

He bent his fingers and, seemingly casually, tapped the cold metal pipe shell three times with the chopstick.

Boom!

Boom!

Boom!

Three muffled sounds stood out starkly in the deathly silent living room.

The sound wasn't loud, but it seemed to possess a peculiar penetrating power.

The moment the third strike landed, an extremely subtle air pressure ripple came from all directions!

Everyone present felt their eardrums swell suddenly, their hearts feel as if they were being squeezed by an invisible hand, and their chests feel tight!

"What...what's going on? Is this just my imagination?"

A young police officer couldn't help but speak, his face turning pale.

Li Mingyu's expression changed, but he remained stubborn.

"Playing tricks!"

Lin Chen put away his chopsticks and casually tossed them back into the food cart, making a crisp "clink" sound.

He turned around, his gaze sweeping indifferently over Li Mingyu's face, which was filled with surprise and doubt, and pointed out the chilling truth that sent shivers down everyone's spines.

"Physical isolation?"

Lin Chen's calm voice shattered Li Mingyu's ridiculous confidence.

"You took apart all the appliances, but you overlooked the largest 'musical instrument' in this house."

He pointed to the ceiling.

"When the length of the central air conditioning duct and the air velocity inside the duct reach a certain golden ratio."

"The ventilation system of this entire mansion is no longer a ventilation system."

"It will become the world's largest and most structurally complex..."

"The Murder Organ!"

The words had barely left his mouth!

hum-

A faint, almost imperceptible low-frequency hum, seemingly capable of penetrating the depths of the soul, suddenly rang out in the room!

The sound didn't come from any direction, but rather from the skeleton of the walls, the depths of the ceiling, and beneath the floor, seeping out from all directions simultaneously, as if the entire villa had come alive and begun to emit its deadly breath!

To everyone's astonishment, the crystal glass that Lin Chen had placed in the center of the marble coffee table began to vibrate silently at a high frequency!

On the surface of the dark red liquid in the glass, strange ripples appeared out of thin air and were becoming increasingly dense at a speed visible to the naked eye!
