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

The atmosphere on the third floor of the mall instantly plummeted to freezing point.

Plainclothes police officers and special police who arrived quickly sealed off the entire floor.

The parents were taken aback by this sudden turn of events.

A cordon has been set up around the children's play area.

The missing girl's mother collapsed to the ground, her face deathly pale, unable to speak clearly.

"Search! Turn over every shop's warehouse, fitting room, and restroom!"

Zhao Ming shouted at the top of his lungs.

Gu Tingchen stood on the outskirts of the amusement area, his gaze quickly sweeping over the surrounding environment.

This is the most crowded area in the mall, with more than a dozen surveillance cameras.

The fact that the suspect dared to make a move here shows that he had extremely high self-confidence.

Song Qianxia did not follow along to search randomly.

She squatted down next to the railing in the playground, carefully examining the floor mats on the ground.

This is where the little girl was last seen.

The nearest surveillance camera is about five meters away.

Five minutes later.

Zhou Zheng's voice came through the walkie-talkie.

"Captain Gu, the person has been found."

"In the fire equipment room on the north side of the third floor."

Everyone's tense nerves instantly relaxed.

Gu Tingchen led Song Qianxia over quickly.

Zhou Zheng was standing guard outside the fire equipment room.

The little girl sat on a cardboard box, her eyes red, clearly having just cried.

She was unharmed and her clothes were neat.

Song Qianxia walked over and immediately noticed the cuffs of the girl's coat.

There was a black feather sticker that was exactly the same as the one from the afternoon.

twice.

The exact same technique.

"What are these bastards after?"

Zhao Ming slammed his fist hard against the wall.

"They stole the child and then left him untouched in the equipment room in less than ten minutes."

"Are they playing us for a fool?"

Song Qianxia shook her head.

She glanced at the fire equipment room in that corner.

"They're not messing with us. They're timing us."

Song Qianxia spoke with extreme calmness.

He was completely unlike his usual carefree self.

"Deputy Captain Zhao, can you do the math?"

"From the children's playground in the south area to this fire equipment room in the north area."

"The straight-line distance is about two hundred meters."

Song Qianxia pointed to the passage outside.

"You need to pass through two clothing retail areas and avoid three security patrol posts."

"And it has to be done without attracting the attention of any passersby."

She turned to look at Gu Tingchen.

"The suspect was testing the waters by taking away a live target capable of resistance."

"How long would it take to move from the target location to a safe blind spot?"

Song Qianxia's voice sounded somewhat cold in the cramped equipment room.

"The boy in the afternoon was five years old."

"This girl is seven years old."

"Both weight gain and changes in height can affect the speed of transfer."

Zhao Ming felt a chill run down his spine upon hearing this.

"Xiao Song, you mean these people are collecting data?"

"What exactly are they trying to do?"

"Rehearsal".

Song Qianxia uttered two words.

"This kind of high-frequency, organized extreme testing is definitely not for the purpose of trafficking ordinary children."

She understands the logic of the underworld all too well.

"They definitely have a large-scale kidnapping plan targeting specific VIPs to follow up."

"Right now, we're just using these children as guinea pigs to optimize their behavior patterns."

Gu Tingchen listened to Song Qianxia's analysis.

He turned around and strode out.

"Zhao Ming, go and seal off the mall's central control room."

"I need to access all the surveillance footage of the movement from noon today until now!"

Fifteen minutes later.

The mall's control room was filled with members of the special task force.

A wall of surveillance screens flickered with a faint light.

Gu Tingchen sat in front of the control panel, his hands moving rapidly across the keyboard.

He quickly segmented and arranged the images from hundreds of cameras.

"Pay attention to the view around the amusement area."

Gu Tingchen selected a specific time period.

On the screen, the little girl was originally playing by the railing.

Suddenly, a figure pushing a large cleaning cart blocked the camera's view.

Only two seconds passed.

The cleaning truck was moved, and the little girl disappeared.

"That hand speed is incredible."

Xiao Wang watched in stunned silence.

"This is practically a magic trick!"

Gu Tingchen slowed down the video to play it frame by frame.

Song Qianxia stood behind him, her eyes fixed on the figure pushing the cleaning cart.

The suspect was wearing a mask and a baseball cap, and was dressed in the mall's uniform for cleaning staff.

He is tall and slender, and his movements are fluid.

"Watch his footsteps."

Song Qianxia suddenly spoke, pointing to the edge of the screen.

When the suspect pushes the cart to turn, he habitually uses his left foot to lean outwards for leverage.

The angle of the shoulders is also very professional.

"This is definitely not an ordinary human trafficker."

Song Qianxia silently made a judgment in her mind.

This is the kind of gait only mercenaries who spend their lives traversing war zones or the underground black market can muster.

This kind of person will do anything for money.

They have received the most rigorous counter-surveillance training.

They know how to use crowds as cover and how to calculate blind spots for cameras.

On the screen, the suspect is seen pushing a cleaning cart, walking at a leisurely pace.

He perfectly avoided all the cameras pointing directly at his face.

No one who passed by him noticed that there was a child hiding in the car.

"That's so professional."

Gu Tingchen stared at the screen.

"He knows the mall's structure and surveillance layout like the back of his hand."

Gu Tingchen turned to look at Song Qianxia.

"You just said this was a rehearsal. So, who do you think their real target is?"

Song Qianxia shrugged.

"That's hard to say. It could be an important figure visiting Jiangcheng, or it could be the heir to one of the richest men in the country."

She spread her hands out.

"It's definitely going to be a big one."

"These kinds of organizations wouldn't bother with so much effort in preliminary testing unless they made tens of millions in profit."

The owl's silhouette became clearer.

The feeling of irritation welled up in Song Qianxia's heart again.

These mad dogs, can't they go somewhere else to wreak havoc?

I just had to pick on her, this lazy bum who wanted to slack off.

Gu Tingchen stood up.

"Notify all district branches to conduct a comprehensive investigation of individuals with prior criminal records who have entered Jiangcheng in the past two weeks."

"Especially those who understand explosives and security technology."

He looked at the cleaning truck on the surveillance screen.

"The fact that the suspect was able to obtain the cleaning uniform means that there was someone inside the mall who was helping him."

"Take all the cleaning and maintenance staff who are on duty today back for questioning."
