I put you in charge of the child, and you raised a monster!

Before the car even arrived home, Qin Zheng called again.

Yang Mi glanced at the incoming call and his brow twitched slightly.

Zhao Lei immediately sat up straight.

"Here it comes, the bell for the start of the police training course has rung."

Shen Ling'er nestled in Yang Mi's arms, her eyes not fully open.

"Be quiet."

Zhao Lei immediately shut up.

Yang Mi answered the phone.

"Captain Qin?"

Qin Zheng's voice was even lower than before.

"What Ling'er said matches up to part of it."

The car fell silent instantly.

Bai Sisi subconsciously looked at Shen Ling'er.

Zhao Lei's eyes widened, and he opened his mouth, but he didn't dare to utter a sound.

Qin Zheng continued, "Old Xu did touch his beard, and there was black powder residue on his hands."

Yang Mi's expression changed slightly.

"He took it?"

"It's not certain yet," Qin Zheng said in a deep voice. "He insists that he didn't take it, but only moved the box during registration."

Shen Ling'er closed her eyes, her voice sounding sleepy.

Did he lie?

Qin Zheng paused for a moment.

"It doesn't look like it."

Shen Ling'er gave a soft "hmm".

"That's because he touched it, but he didn't know."

Qin Zheng was startled.

"What do you mean?"

Shen Ling'er slowly opened her eyes, her face still showing the languor of someone who had just woken up.

"The box is missing, but that doesn't necessarily mean someone took it."

Zhao Lei finally couldn't hold back anymore.

"If someone didn't take the box, who else could have?"

Shen Ling'er looked at him.

"Didn't you just say long legs run?"

Zhao Lei: "……..."

Bai Sisi chuckled, then quickly covered her mouth.

Shen Ling'er rubbed her eyes and continued, "The box wasn't lost."

Qin Zheng's voice immediately turned serious.

How do you determine this?

Shen Ling'er sat up a little straighter while holding the account book.

"Old Xu touched the edge of the box, and his hands were covered in black ash."

"If the box is switched, the person who took it will also get one."

"But you investigated Lao Xu first, which means no one else did."

Qin Zheng's side quieted down.

Shen Ling'er said calmly, "So the box is still in the evidence room."

Zhao Lei looked much more energetic.

"It's still there? But didn't Captain Qin say the empty box was there?"

Shen Ling'er looked at him.

"He said the small box was missing, then he said the empty box was there."

Zhao Lei was stunned.

Bai Sisi also realized what was happening.

"Yes, is it the brass clasp inside that's missing, or the whole box?"

On the other end of the phone, Qin Zheng's voice turned somber.

"At first, the missing item was the brass clasp, but the registrar said the box had also been moved, so everyone assumed the box had been switched."

Shen Ling'er nodded.

"Bad guys like to let you find the big shots first."

Zhao Lei slapped his thigh.

"Got it! I made you think the box had been switched, but what's really missing is the button!"

Shen Ling'er looked at him.

"You look a bit like you've been to school today."

Zhao Lei's eyes lit up.

"Bonus points?"

Shen Ling'er said calmly, "No."

Zhao Lei: "..."

Bai Sisi laughed so hard her shoulders shook.

Qin Zheng's side already had people communicating in hushed tones.

After a few seconds, he asked, "Ling'er, where might that copper clasp be?"

Shen Ling'er thought for a moment.

"In the box."

Qin Zheng: "..."

Zhao Lei: "..."

Everyone in the car fell silent.

Zhao Lei cautiously spoke up: "Teacher Ling'er, Captain Qin said the copper buckle is missing."

Shen Ling'er calmly said, "Not seeing you doesn't mean you're not here."

Zhao Lei slowly turned his head to look at the camera.

"Dear viewers, after hearing this, I feel that things are starting to get complicated again."

The live chat exploded.

"They're here! They solved the case as soon as we got off the plane!"

"Not seeing doesn't mean not being there—that's a great line from Shen Fei!"

"She was so sleepy she could barely keep her eyes open, yet her mind was still so clear."

"Captain Qin: Something's missing. Ling'er: Don't panic, it might just be hiding."

"I now seriously doubt that the police should issue Ling'er a consultant certificate."

Qin Zheng lowered his voice.

"We've checked the box; it's empty."

Shen Ling'er asked, "Does the box have a hidden compartment?"

Qin Zheng: "Preliminary examination revealed nothing."

Shen Ling'er continued, "Was there a lining inside?"

Qin Zheng paused.

There is a layer of black velvet.

Shen Ling'er nodded.

"Feel the edge of the velvet fabric."

Footsteps immediately came from Qin Zheng's side.

A few seconds later, Qin Zheng walked into the evidence room as if he were himself.

The faint sound of gloves rubbing together could be heard over the phone.

Holding the account book, Shen Ling'er said slowly, "Old boxes won't keep old things smooth."

"Brass buckles will leave marks if pressed for a long time."

"If you remove the button, the mark will still be there."

"If the mark isn't right, it means the button wasn't removed."

Qin Zheng's breathing paused noticeably.

Zhao Lei's scalp tingled.

"What do you mean by 'the print is wrong'?"

Shen Ling'er looked out the window.

"I'll remember where I left things."

Zhao Lei was stunned.

"You remember things too?"

Shen Ling'er said calmly, "Things are more honest than people."

Zhao Lei was instantly excited.

"They're back! The classic quotes are back!"

Bai Sisi couldn't help but laugh.

"Zhao Lei, you're watching like you're following a new episode of a TV series."

Zhao Lei was very serious.

"Shen Family Classroom Quotes: Missing even one is a loss."

On the other end of the phone, Qin Zheng suddenly spoke.

"Found it."

The car fell silent.

Yang Mi's grip on the phone tightened slightly.

"Found it?"

Qin Zheng's voice was clearly trembling.

"The brass buttons are underneath the velvet."

"The edges of the velvet have been pressed back in, so it's not noticeable to the naked eye."

Zhao Lei stood up abruptly, nearly hitting his head on the roof of the car.

"It's really in the box?!"

Shen Ling'er looked at him.

"sit down."

Zhao Lei immediately sat down.

"Okay, teacher."

Qin Zheng continued, "There is a very thin lining at the bottom of the box, and the copper clasp is inserted inside."

"It's not lost."

"Someone deliberately made it disappear."

Yang Mi frowned.

"What's the purpose?"

Shen Ling'er touched the cover of the ledger with her small hand.

"To make you doubt Old Xu."

Qin Zheng remained silent.

Shen Ling'er continued, "Old Xu will be the last to register."

"He has a beard."

"His hands were dusty."

"The item is missing again."

"Everyone will be watching him."

Zhao Lei felt a chill run down his spine.

"So Old Xu was set up?"

Shen Ling'er nodded.

"An honest person, if stared at for too long, will look like a bad person."

No one spoke for a moment in the car.

Qin Zheng's voice was very deep.

"Ling'er is right."

"Old Xu has been in charge of physical evidence registration for over 20 years. He is cautious by nature, but also timid."

"If we press him too hard today, he might say something inappropriate."

Zhao Lei took a slow breath.

"That's too sinister."

Bai Sisi said softly, "Hide the things where they were, and then make it look like someone else has tampered with them."

Shen Ling'er said calmly, "Thieves love it when others find them."

Zhao Lei immediately turned his head.

"Mr. Shen's quotes?"

Shen Ling'er nodded.

"That's what my dad said."

Zhao Lei took a deep breath and looked at the camera.

"Dear viewers, although Mr. Shen is not at the police station, he has solved another case."

The live chat went wild instantly.

"Hahaha, Shenfei just sits at home, and the case solves itself!"

"Thieves love it when others find them; that's a brilliant saying."

"Ling'er found the physical evidence before even arriving at the scene?"

"Is this reasonable? No, it isn't. But she is Shen Ling'er."

"Captain Qin, could you call the Shen family hotline first when handling cases in the future?"

"Who exactly is Shen Fei?! He even taught his daughter how to use physical evidence to frame someone?"

Qin Zheng quickly asked again, "Ling'er, who made it?"

Shen Ling'er looked down at the new account book, her voice calm.

"Who most wants Old Xu to get into trouble?"

Qin Zheng's side fell silent.

Shen Ling'er continued, "Old Xu is in charge of the registration."

"If he gets into trouble, all the previous registrations can be questioned."

"Previous evidence will also be questioned."

Qin Zheng's voice suddenly turned cold.

"Someone wants to overturn the entire chain of evidence."

Yang Mi's expression changed slightly.

Zhao Lei also realized what was happening.

"It's not about stealing the brass buckle, but about undermining the credibility of the police's physical evidence?"

Shen Ling'er nodded.

"Stealing is a minor matter."

"The real problem is that people don't believe you."

The car fell silent again.

That's too simplistic a statement.

But when it came down, it was as if the true purpose of the whole thing was laid bare.

Soon, the sound of Qin Zheng flipping through documents came from his side.

"The people who have recently been in contact with the evidence room, besides Lao Xu, include Xiao Zhou from the technical department, Sister Li from the archives, and Xiao Ma, the auxiliary police officer on duty..."

Shen Ling'er asked, "Who reminded you that you lost something?"

Qin Zheng paused.

A few seconds later, his voice turned cold.

"Xiao Zhou."

Shen Ling'er then asked, "Did he speak up for Old Xu?"

Qin Zheng paused for a moment.

"have."

Zhao Lei was stunned.

"Is it a problem to speak up for him?"

Shen Ling'er looked at him.

"Helping too quickly is like pushing."

Zhao Lei was stunned.

Bai Sisi whispered, "On the surface, they're helping Lao Xu, but actually they're trying to get everyone's attention to him."

Shen Ling'er nodded.

He said Old Xu wouldn't take it.

"People will wonder, why are you so sure?"

Zhao Lei touched his arm.

"This person is too cunning."

Shen Ling'er said calmly, "More than you."

Zhao Lei: "..."

Qin Zheng's side has become completely serious.

"I see."

"I will first check Xiao Zhou's operation records and entry and exit times."

Shen Ling'er thought for a moment.

"Don't rush."

Qin Zheng: "Hmm?"

Shen Ling'er said, "Let Old Xu go get some water."

Qin Zheng was startled.

Zhao Lei was also stunned.

Why?

Shen Ling'er said calmly, "Bad people are waiting for him to panic."

"He's not panicking; it's the bad guys who are."

Qin Zheng remained silent for a few seconds.

Then he chuckled softly.

"Understood."

After hanging up the phone, no one spoke in the car for a long time.

Zhao Lei slowly turned his head to look at Shen Ling'er.

"Teacher Ling'er."

Shen Ling'er looked up.

"what?"

Zhao Lei said seriously, "I really think I can't enroll in the police station's continuing education program now."

Shen Ling'er nodded.

"Your foundation is weak."

Zhao Lei: "........."

Bai Sisi laughed out loud.

Yang Mi couldn't help but laugh.

Not long after.

News of Qin Zheng came again.

As expected, Xiao Zhou gave himself away.

He was only in charge of technical archiving and shouldn't have been near the evidence cabinet.

However, in the surveillance footage from that day, he took the opportunity of helping Lao Xu move boxes to linger at the evidence table for seven seconds.

Seven seconds.

It was just enough to lift the box lining, insert the brass clasp, and then flatten the velvet cloth.

More importantly...

After Qin Zheng told Lao Xu to go get some water and paused the questioning, Xiao Zhou clearly couldn't sit still any longer.

He offered, "Should we check Old Xu's registration box again?"

It was this sentence that made Qin Zheng completely certain of his direction.

Further investigation is needed.

Sure enough, there was a deleted overseas call record on Xiao Zhou's phone.
