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

Lin Chen gently stroked Su Ke'er's trembling back with his large hand.

That warm and steady force gave Su Ke'er's heart, which was being torn apart by fear, an anchor point where it could find rest.

He didn't speak again, but instead offered silent comfort with the gentlest gestures.

Li Mingyu's noisy and smug voice was still chattering outside the door.

"I already said, it's all about overwork and sudden death!"

"Young people these days just don't know how to take care of their bodies. They push themselves to this point for a performance. Why bother?"

"Captain Su, I think we shouldn't waste police resources. Let's call it a day!"

Su Qingge kept a cold face and couldn't be bothered to pay him any attention.

Just then, a cool and aloof figure strode in, the hem of her white trench coat stirring a gentle breeze.

It is Jiang Tingxue.

After receiving Su Qingge's call, she rushed over from the bureau immediately.

Seeing Su Ke'er trembling in Lin Chen's arms, Jiang Tingxue's eyes flickered for a moment, but she quickly regained the composure of a professional forensic doctor.

She didn't disturb Lin Chen, but went straight to the body, put on white gloves, squatted down, and began a preliminary examination.

Time passed second by second.

Jiang Tingxue's brows furrowed deeper and deeper.

She stood up, walked to Lin Chen's side, her voice extremely low, her expression extremely solemn.

"Something is very wrong."

Lin Chen helped Su Ke'er, who had cried herself to exhaustion and whose emotions had calmed down a bit, to sit down on a chair next to her before turning to look at Jiang Tingxue.

"How so?"

"The deceased had no external injuries or signs of poisoning. The failure of all vital signs pointed to typical sudden cardiac death."

Jiang Tingxue paused, her tone filled with confusion.

"However, I found very slight signs of rupture in both of her eardrums, as if they had been damaged by some kind of invisible sound waves."

"Even more bizarrely, her heart, liver, lungs, and other major organs all showed extensive petechial bleeding, as if their tissue structure had been shredded from the inside by some strange force!"

"This is not how sudden death should be!"

Upon hearing this, Li Mingyu, who was eavesdropping at the door, changed his expression, but still stubbornly snorted.

"They're just making things up! Maybe the deceased had some congenital disease!"

Lin Chen completely ignored him.

Ruptured eardrum... comminuted bleeding of internal organs...

His brain worked at high speed, connecting these two seemingly contradictory clues.

next second.

Lin Chen slowly closed his eyes.

[God-level hearing], unleashing full power!

Om-!

The whole world went silent in an instant.

The sounds of police officers talking, Su Ke'er's suppressed sobs, and the traffic noise in the distance...

Everything disappeared.

Instead, a bizarre and wonderful sound wave universe composed of countless frequencies and wavebands has emerged!

Every residual vibration in the air, every echo reflected from the wall, was precisely captured, analyzed, and reconstructed into a three-dimensional sound map in his mind.

He can "hear" the density of the wall material.

You can "hear" the air flowing under the wooden floor.

In this absolute silence, Lin Chen's consciousness detected an extremely faint yet stubbornly persistent vibration in the air.

It was a wave with an extremely low and deep frequency, below the limits of human hearing.

It was like a colossal beast lurking in the abyss, its chilling breath still lingering in the air even after its death.

The source of this lingering tremor points directly to...

A corner of the music room!

Lin Chen suddenly opened his eyes, and a cold, piercing glint flashed in his deep pupils!

Without uttering a word, he strode to the corner of the music room amidst the puzzled gazes of everyone.

There, there was an unremarkable bass compensation speaker used for music teaching.

"Lin Chen, what are you doing? That's just a broken speaker..."

Li Mingyu spoke up subconsciously.

Lin Chen still ignored him.

His fingertips gently traced the black dustproof mesh on the speaker's surface.

[God-level Mechanical Mastery], activated instantly!

In the instant his finger swept across the speaker, the speaker's complex internal structure—from the layout of the circuit boards and the types of capacitors to the winding method of the speaker coils—was transformed into an incredibly clear three-dimensional structural diagram in his mind.

Then, on this perfect structural diagram, he saw something that shouldn't exist.

A foreign object that is cleverly disguised and perfectly integrated with the original circuitry!

found it!

Lin Chen's eyes suddenly turned fierce.

Without any further hesitation, he formed his right hand into a claw, his five fingers like hooks, and directly gripped the seam of the speaker!

"Open it!"

A low shout.

He suddenly exerted his strength!

"Sizzle—!"

A sickeningly loud thud of metal tearing and wooden planks shattering.

He used brute force to break and tear apart the sturdy speaker shell that was secured with high-strength screws!

Wood chips and plastic scraps flew everywhere!

Li Mingyu, standing at the door, was so frightened that he fell to the ground with a thud, while the young police officer behind him dropped his notebook with a "thud," his face showing an expression of utter disbelief.

Amidst everyone's horrified gazes, Lin Chen threw the torn speaker casing on the ground, revealing the complex circuit boards and speaker units inside.

His hand reached in with perfect precision, ripped off several disguised wires, and then yanked them sharply!

An illegal high-frequency sound wave generator, about the size of a palm, with an extremely precise design, made entirely of black metal, and flashing with an eerie red light, appeared in his hand!

The entire venue fell into a deathly silence.

Everyone was stunned by what they saw, leaving their minds blank.

"What...what is this?"

Su Qingge was the first to react and asked in a trembling voice.

Lin Chen raised the device in his hand, which was still slightly warm, and revealed the chilling truth word by word.

"This is not sudden death."

"This was a meticulously planned, perfect, and invisible murder!"

His cold gaze swept across the entire room, his eyes lingering slightly on the scattered sheet music on the floor, landing on a high G repeatedly circled in red, before turning to Jiang Tingxue.

"Tingxue, you said the deceased's internal organs seemed to have been shredded from the inside by a strange force."

"What if this power is sound?"

Jiang Tingxue's pupils suddenly contracted!

Lin Chen continued.

"The killer exploited the fact that infrasound frequencies below 20 Hz are imperceptible to the human ear, precisely tuning the generator's frequency to the same resonant frequency as the human heart and internal organs!"

"He hid the murder device inside a speaker and set up a voice-activated trigger."

Lin Chen's voice wasn't loud, but it struck everyone's heart like a hammer blow.

"The trigger condition is the highest note that's repeatedly marked on that musical score!"

"Whenever Chen Man plays that specific note on her violin during practice, this device will be triggered instantly!"

"In that instant, a deadly infrasound bursts forth in a fan-shaped area, resonating with her internal organs and shattering them completely from the inside out in less than a second!"

"Killing without leaving a trace!"

Lin Chen's words cleaved through all the fog surrounding the case, revealing the hideous and terrifying truth behind it.

A collective gasp filled the air, and everyone involuntarily took a step back.

Killing someone with a sound you can't hear!

What a bizarre and vicious method this is!

Li Mingyu slumped to the ground, staring at the black metal block in Lin Chen's hand. His face, which had been trying to argue, was now flushed red like a pig's liver and filled with deep-seated fear.

His previous statement about "dying from overwork" now sounds so ridiculous and so foolish!

Jiang Tingxue's gaze toward Lin Chen had long since lost its previous solemnity and confusion, replaced by an almost boiling brilliance and admiration!

She couldn't imagine what kind of profound knowledge a person would need to see through such an unbelievable method of committing a crime in such a short time!
