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

The moment Lin Chen finished speaking, the arrogant virtual puppet on the computer screen seemed to have its throat gripped by an invisible hand, and its morbid smile froze on its face.

Immediately afterwards, the entire image began to flicker and distort violently, as if it had been eroded by a virus, and finally collapsed into a bunch of meaningless gibberish with a "sizzle".

The connection was forcibly severed by Lin Chen in a more domineering and unreasonable manner.

Su Qingge leaned against Lin Chen's back and could even clearly feel that Lin Chen's body temperature seemed to drop several degrees in that instant. The cold killing intent emanating from him made even the head of the serious crime squad, who was used to seeing life and death, feel a chill in her heart.

But soon, the coldness receded like a tide, and Lin Chen's body relaxed again.

He turned his head and looked at the beautiful woman in his arms, whose pretty face was slightly pale from anger and worry. A soothing smile appeared on his lips, and he reached out and gently stroked her delicate nose.

"What's wrong? Scared by a clown jumping around?"

"I didn't!"

Su Qingge stubbornly retorted, but pressed her body even closer to his, feeling the strong heartbeat from his chest, and her unease gradually subsided.

"That bastard, he actually dared... dared to threaten you with us!"

Just thinking about the puppeteer's perverted remarks made Su Qingge so angry that she wanted to drag him out right now, handcuff him to the chair in the interrogation room, and let him taste the iron fist of the people's police.

"Don't worry, he won't be able to keep this up for long."

A hint of amusement flashed in Lin Chen's eyes.

"He thought he was on the fifth level, little did he know, I was already watching his performance from the stratosphere."

As he spoke, he started playing the extremely pure background audio file, which he had intercepted and filtered out of all electronic interference, on his computer in a loop.

"Clang...clang...clang..."

The melodious and ancient sound of the bell echoed in the quiet study.

"Boom... Boom..."

A dull, rhythmic vibration followed.

Su Qingge listened intently for a long time, her delicate brows furrowing slightly.

"What is that? It sounds like bells and a train passing by?"

You're half right.

Lin Chen smiled, picked up her soft, delicate body, and let her sit on his lap. Then, pointing to the pulsating sound wave diagram on the screen, he began his performance.

……

The next morning, in a top-secret conference room at the Beijing General Bureau, the atmosphere was so oppressive it was hard to breathe.

Li Mingyu, along with several of the top cybersecurity and acoustic analysis experts from the Beijing branch, were gathered around a high-precision audio analyzer, their faces etched with worry and their foreheads covered in sweat.

"No, Deputy Captain Li, the background noise in this audio is too weak, and it's mixed in with the electronic sound of the voice changer. Even with the best equipment for triple filtering, we can only separate out some meaningless white noise."

An acoustics expert with graying hair took off his headphones and said with a helpless expression.

"What about tracking? What about the other party's IP address?"

Li Mingyu eagerly asked the cybersecurity expert on the other side.

"Don't even mention it."

The cybersecurity captain looked utterly dejected.

"The other party is a top expert. The signal source repeatedly jumped around in zombie networks in hundreds of countries around the world, and finally disappeared in a weather station server in the Arctic."

"Our people were just about to delve deeper into the investigation when the other side reverse-engineered a virus, almost breaching the entire internal network firewall single-handedly! If it weren't for the timely power outage, our headquarters would have been on the front page this morning!"

"Useless! They're all useless!"

Li Mingyu slammed his fist on the table in anger, but there was nothing he could do.

He knew it wasn't that his subordinates were incompetent, but rather that the "puppet master" was far too cunning and powerful.

Just as the conference room fell into a deathly silence of despair, the door was pushed open.

Lin Chen walked in yawning, looking sleepy and lazy, followed by the dashing Su Qingge.

"Advisor Lin!"

Li Mingyu felt as if he had seen a savior and rushed to greet him.

The experts in the conference room looked at Lin Chen, who was so young, with suspicion and confusion.

Especially after these tech gurus had just suffered a crushing defeat, the arrival of an outsider seemed more like an irony to them.

Ignoring everyone's gaze, Lin Chen walked straight to the high-precision audio analyzer and said lazily.

"Give me the original file of that audio clip from last night."

"Advisor Lin, this..."

The acoustics expert hesitated. This equipment was his prized possession, and its operation was extremely complicated. He was afraid that Lin Chen, an amateur, would break it.

"Give it to him."

Su Qingge spoke coldly, leaving no room for argument.

The experts dared not say anything more and reluctantly pulled out the original documents.

Lin Chen didn't even glance at the complicated control panel; he simply listened to the recording coming from the speakers, which was mixed with harsh electronic sounds and faint static.

Once.

Twice.

Just when everyone thought he was also at a loss, Lin Chen suddenly spoke up.

He unlocked the [God-level Vocal Mastery] and [God-level Meteorology Mastery] levels.

"The bell's resonance frequency is between 438 and 442 Hz. The bell body is made of bronze with a tin content of about 22%, which is typical of the casting technology of German Gothic church bells from the late 19th century."

Lin Chen's voice wasn't loud, but every word he uttered was like a bombshell, exploding in the conference room.

All the experts suddenly looked up, staring at him as if he were a monster.

Is this...is this something a human could hear?

Do you think you're a tuner?

Lin Chen continued without pausing.

"This kind of bell sound can only be heard in one place in the entire capital."

"That's the Western-style clock tower in the university town of Beijing, which was originally built in 1898."

"Furthermore, I heard a slight attenuation and echo refraction during the propagation of the bell. Considering that the air humidity in Beijing was 85% and the northwest wind speed was 1.5 meters per second at 4 a.m. this morning, the straight-line distance between the other party's recording equipment and the Bell Tower was between 1.8 kilometers and 2.1 kilometers."

"hiss--"

A collective gasp filled the room. The white-haired acoustics expert's mouth was agape, wide enough to fit an egg, and he didn't even notice when his thermos clattered to the ground.

This is no longer acoustic analysis; this is metaphysics!

"And this..."

Lin Chen pointed to the almost negligible low-frequency vibration waveform on the screen.

"This isn't a train, it's a subway."

"The vibration frequency is stable at 12 Hz, and the period is extremely regular, occurring once every 3 minutes and 15 seconds."

"This is exactly the standard train interval for the Beijing Metro Line 4 during the off-peak hours in the early morning, between University Town South Station and University Town North Station."

"Furthermore, based on the attenuation model of vibration transmission through the geological layer, the foundation of the building where the other party is located uses C30 strength concrete and has undergone double-layer seismic isolation treatment."

"In the university town area, only high-rise apartments or research buildings constructed within the last five years would use this type of building."

After Lin Chen finished speaking, he picked up the marker on the table, walked to the huge electronic map of Beijing, and drew a circle with a diameter of less than two kilometers with the clock tower of the university town as the center.

"The puppeteer's hideout, or rather, the studio where he carried out his online crimes last night, is within this area!"

The entire conference room was deathly silent.

All the experts, including Li Mingyu, were frozen in place, their minds blank.

They worked all night, using hundreds of millions of dollars worth of equipment, but they couldn't even analyze a single thing.

With just his ears, Lin Chen pinpointed the area to a specific block in just a few minutes, and even "heard" the foundation materials of the other party's buildings!

Is this even human?

This is a miracle!

"I...I'll take men to search right away!"

Li Mingyu was the first to react, his voice trembling with excitement.

"Don't rush."

Lin Chen stopped him, his eyes becoming deep and playful.

"Puppet masters are extremely arrogant; they enjoy the thrill of being in control of everything."

"If you launch a large-scale search now, you'll only alert him and make him feel like his game has been abruptly interrupted."

"Then... what should we do?"

A hunter's smile curled at the corners of Lin Chen's mouth.

"Doesn't he like playing video games?"

"Then I'll personally join him and play along."
