We asked you to solve cases, and here you are sharing your criminal experiences?

Time passed by, second by second.

The numbers on the countdown clock turned a glaring red.

00:55:00.

Less than an hour remained.

The water in the pool had reached the thighs of the three wealthy merchants. They were shivering with cold, and whimpering in despair.

The masked judge sat in a grand chair next to him, holding a glass of red wine, leisurely watching the revelry in the barrage of comments.

"Captain Gu, this won't work!" Zhao Ming ran over with a thick stack of documents.

"In recent years, with urban planning and renovation in Jiangcheng, there have been far too many abandoned and closed commercial buildings!"

Zhao Ming was so anxious that he kept rubbing his hands together.

"There are a total of 47 abandoned shopping malls in the city that meet the criteria of having a ceiling height of over five meters and no windows!"

"Even if we send out all the police officers from every police station to search house by house, we still wouldn't be able to finish in two hours!"

Gu Tingchen's expression was cold and stern.

A city-wide rollout is clearly impossible. If we alert the enemy, the judge might press the execution button prematurely.

"Any progress on the online tracking?" Gu Tingchen asked, looking towards the cyber police.

Director Qin shook his head in utter despair.

"A dead end. This bastard used a rare set of low-level code to directly lock the reverse tracing port. Unless we have a top-tier hacker like the one from Cyrillic State helping us, we definitely won't be able to find the IP today."

Completely clueless.

The entire case seemed to have reached a dead end.

Song Qianxia stood on the periphery of the crowd, her hands in her pockets.

She looked at the three fat men on the screen who were about to drown.

She didn't care whether those three guys lived or died. In her past life in the underworld, she had killed people a thousand times worse than them.

The problem is, if the task force messes up today, Gu Tingchen, the team leader, will definitely be punished.

If this ruthless devil is in a bad mood, he'll definitely dock her wages and bonuses like crazy.

Protecting your wallet is of utmost urgency.

Song Qianxia sighed and walked to Director Qin's computer.

"Director Qin, could I borrow your best monitoring headphones?"

Director Qin was taken aback for a moment, then quickly handed over the professional noise-canceling headphones hanging around his neck.

Song Qianxia put the headphones on her head.

She picked up the mouse and opened the audio control panel for the live stream.

"What are you going to do?" Lin Wan couldn't help but ask from the side.

Song Qianxia ignored her.

Her fingers flew across the keyboard, directly loading a complex audio filter plugin.

then.

Song Qianxia closed her eyes.

Isolated from all external distractions, she focused all her attention on the sound coming from her headphones.

In his previous life, he was the Thousand Faces of the Underworld.

She honed an abnormal level of environmental awareness amidst a hail of bullets. Sometimes, in complete darkness, she could only rely on her hearing to determine the enemy's location and the structure of buildings.

The sound in the live stream was very noisy.

The judge's voice changer, the sounds of three wealthy merchants struggling, and the rushing sound of water.

Song Qianxia pulled the equalizer.

Cut off all human voice frequencies.

Reduce the high-frequency sound of water flow.

Turn the background noise up to the maximum.

Suddenly, a hissing and resonant sound, unbearable to most people, came through the headphones.

But in this chaotic noise.

Song Qianxia had grasped what she wanted.

"Tick-tock—tick-tock—"

This isn't the sound of a leaking pipe. It's the echo of water dripping from the old cement wall onto the metal pipes due to long-term dampness.

"Buzz—Buzz—Buzz—"

A series of very regular, low-frequency rumbling sounds.

The sound was so faint that an ordinary person would mistake it for the sound of the wind.

But to Song Qianxia, ​​this frequency was all too familiar.

This is the friction sound made by the rotating bearings of an old-fashioned large industrial exhaust fan with Freon after it has aged.

"Clang! Clang!"

Just then, a dull tremor traveled through the building's load-bearing walls and into the microphone.

Song Qianxia suddenly opened her eyes.

She ripped off her headphones and tossed them onto the table.

"Found it." Song Qianxia's voice was clear and loud.

All eyes immediately turned to her.

"West of the city." Song Qianxia walked to the map and picked up a red pen.

"First of all, there must be a freight railway line or a high-speed rail line near this abandoned shopping mall."

Song Qianxia speaks very quickly.

"Just in those ten seconds, the background noise of the live broadcast could be heard as a heavy-load train passed by, producing low-frequency vibrations on the ground."

"That kind of 'clanging' sound can only be produced by freight trains with more than 22 carriages."

Everyone was stunned.

"Secondly," Song Qianxia said, pointing to the map.

"That buzzing noise from the exhaust fans. All the new shopping malls now use silent central air conditioning."

"Only old-fashioned shopping malls built 20 years ago use those giant blade external cooling rooms."

Song Qianxia drew a large circle on the map of western Jiangcheng with a red pen.

"West of the city. Less than 500 meters from the freight railway line. And it's an old shopping mall built 20 years ago."

Song Qianxia looked at Zhao Ming.

"Deputy Captain Zhao, bring out the list of forty-seven candidates and check it against the list."

Zhao Ming was completely stunned. He quickly flipped through the documents in his hand, his fingers flying across them.

Excluded. Excluded. Excluded.

One minute later.

Zhao Ming suddenly raised his head, his eyes wide open like copper bells.

"It matches up!" Zhao Ming's voice trembled with excitement.

"There's only one place in the entire Jiangcheng that meets all three of these stringent conditions!"

"West of the city, Great World Shopping Plaza!"

Zhao Ming read aloud from the documents.

"That was the largest commercial complex in Jiangcheng twenty years ago. It was shut down completely eight years ago because it failed to meet fire safety standards."

"It's exactly 450 meters from the western suburban freight railway transfer station!"

The entire audience gasped.

Lin Wan looked at Song Qianxia with the eyes of someone looking at an alien. "You...you pinpointed the location just by listening to a few noises?"

This is ridiculous! It's even more sensitive than a police dog's ears.

Song Qianxia stretched out her little finger and picked at her ear.

"Well, I don't have any other skills, but I have exceptionally good hearing."

She continued to uphold the fine tradition of talking nonsense.

"You don't know, the urban management officers are very strict in cracking down on roadside vendors. When I was selling grilled cold noodles at the night market, I could hear the urban management officers' engines as soon as they were two kilometers away."

Song Qianxia boasted without batting an eye.

"To save my tricycle, I developed super hearing."

Gu Tingchen stood to the side, watching her nonsensical behavior.

The corner of the man's mouth twitched almost imperceptibly.

"Practicing tactical rolls by shooting balloons. Developing radar-like hearing by selling grilled cold noodles." Gu Tingchen looked at her with deep eyes.

"Song Qianxia. Did you previously run a night market in Jiangcheng, or did you fight in Syria?"

Song Qianxia coughed twice and quickly looked away.

"Captain Gu, what are you saying? I'm a model young man with impeccable morals. Are we going to the Great World Plaza or not? If we don't go soon, those three fat guys are really going to turn into boiled meat slices."

Gu Tingchen didn't waste any more time asking questions.

He drew his sidearm from his waist and cocked it with a click.

"Zhou Zheng! Notify the SWAT team to take off immediately! Target: Top floor of the West City World Shopping Plaza!"

Gu Tingchen grabbed the walkie-talkie and gave a stern order.

"Everyone in the task force, gather your gear. Assemble in the parking garage downstairs in five minutes!"

"Let's go and meet this so-called judge now!"
