Detective: I, Cao Jianjun, started by arresting my brother-in-law.

very short.

It's probably only seven or eight centimeters long.

Guan Hongfeng was very confused: "Captain Cao, what... does this mean?"

"Take this."

As Cao Jianjun spoke, he stuffed two strands of hair into Guan Hongfeng's hand: "Send them, along with Wu Lingling's DNA sample, to Gao Yanan for testing."

"???"

Guan Hongfeng looked on with a puzzled expression: "Captain Cao, whose hair is this?"

"Go ahead and do it, you'll know when you get back."

Cao Jianjun smiled mysteriously: "I'll tell you when the results come out."

Guan Hongfeng thought Cao Jianjun was incredibly awesome, ridiculously awesome.

His previous crime-solving skills seemed utterly useless in front of Cao Jianjun.

Let's not talk about Wang Zhige's case; he anticipated the actions of the mastermind behind the scenes.

Now, somehow they've gotten someone else's hair, and it's even connected to Wu Lingling, who was mistakenly killed two years ago.

…………

Since Cao Jianjun returned, the Changfeng Detachment has been shrouded in an inexplicable sense of oppression.

Zhou Xun didn't leave all afternoon and kept Xiao Wang tied to his side the whole time.

Guan Hongfeng stayed at Gao Yanan's forensic office, waiting for the DNA test results.

Cao Jianjun took Zhou Shutong to the monitoring room.

"Captain Cao..."

Several police officers in the police station's monitoring room stood up to greet Cao Jianjun as he entered.

"Okay, everyone, please sit down."

Cao Jianjun, appearing very approachable, casually patted a police officer on the shoulder and said, "Help me check the surveillance footage, the one from the cell."

"Okay! When?"

The officer quickly sat down and started operating the computer.

"The night before yesterday."

As soon as Cao Jianjun finished speaking, the two police officers were stunned. They smiled awkwardly, turned around, and looked at Cao Jianjun with embarrassment.

"Captain Cao... Captain Cao..."

"what happened?"

"The surveillance footage from the cell the night before last is missing for some reason."

The two police officers pursed their lips sheepishly: "We...we only slept for a short while and then we discovered that fifteen minutes of surveillance footage was missing."

"..."

Although this was a very important mistake.

But Cao Jianjun felt no surprise at all.

Imagine someone in a police uniform passing a message to Wang Zhige in the cell corridor; it would be incredibly stupid if they could be caught on camera.

"Was it not saved, or... was it not captured?"

Cao Jianjun is very worried about this issue.

"There shouldn't be a village chief."

The two officers stood up somewhat awkwardly and stood aside: "That night, I... I don't know why, I was just really sleepy."

"Then I fell asleep on the table and didn't wake up for about half an hour."

"I didn't notice at the time; everything looked fine on the security camera."

"It wasn't until the next day when I went to work that I discovered the surveillance footage from my cell didn't match up."

Hear the words.

Cao Jianjun nodded expressionlessly; he was still thinking about how to resolve the situation.

Zhou Shutong, however, thought Cao Jianjun was angry and started scolding the two auxiliary police officers who were monitoring the surveillance cameras.

Neither of them dared to speak, standing obediently against the wall like students being scolded.

At this time.

Cao Jianjun quietly opened the system.

"Ding! Welcome back, host. How can I help you?"

"System! Do you have a skill that can restore surveillance footage?"

As Cao Jianjun inquired, he used his consciousness to manipulate the system panel, trying to find skills that could help.

"Yes, host."

The system replied: "This technology is a skill that cyber police officers should possess."

As the introduction progresses, the system panel automatically switches to this type of page.

There aren't many types of network technologies; they can be categorized into three levels: high, medium, and low.

"What level of skill does the host require?"

The system displays the technical value of the three levels on the screen.

Advanced technology, 150,000 affinity points.

Medium skill level, 100,000 affinity points.

Low-level technology, 50,000 intimacy level.

"Of course it's higher level."

Cao Jianjun looked at his popularity rating, which had reached 1.8 million. He was rolling in money, so why was he still worried?

"Okay, the system will purchase the technology for the host shortly."

With the prompt of the virtual electronic voice, the skill of advanced network technology was successfully activated.

Immediately.

Cao Jianjun felt his mind go completely black, and he instinctively felt dizzy.

His body, which had been standing, could no longer support him, so he leaned on a chair and sat down.

About ten seconds later, consciousness returned to normal in the central nervous system.

When Cao Jianjun opened his eyes again, he clearly remembered more skills related to network technology.

Without any hesitation, Cao Jianjun quickly started operating the computer with both hands, using the network to search for the monitoring terminal.

When searching for the original monitoring footage on the terminal, it was discovered that fifteen minutes of the recording on the terminal had also been formatted.

This proves that the surveillance footage was captured at the time.

However, the local monitoring records and cloud records were later deleted.

As long as he has the memory, Cao Jianjun is no longer worried.

With hands flying across the keyboard, searching through source code, the scene was restored three minutes later in the vast world of the internet.

Snapped!

With the press of the Enter key, starting at 1:10 a.m. the night before last, the surveillance footage of the cell corridor was found.

See this scene.

Zhou Shutong quickly came over, staring at Cao Jianjun in astonishment, then widening her almond-shaped eyes and staring intently at the surveillance screen.

"~Is it...him?"

Zhou Shutong recognized the police officer in the surveillance footage and asked, "Xiao Chen?"

Cao Jianjun didn't know who Xiao Chen was, but he did recognize the police officer in the picture.

It was none other than the corrupt cop from the original TV series "Day and Night" who originally wanted to assassinate Ye Fangzhou, but was killed by Ye Fangzhou in the car.

He was a young man, and also a police officer in the Changfeng branch.

"Did Xiao Chen come to the team today?"

Cao Jianjun quickly got up.

"I...I don't know."

Zhou Shutong looked completely bewildered.

It's understandable. The police station isn't exclusive to the Changfeng branch; there are other police units involved, especially the officers guarding the detention cells, who don't belong to the Changfeng branch but to the Changfeng sub-bureau.

Therefore, it's normal that Zhou Shutong doesn't understand.

"Arrest them immediately."
