Team Leader Zhuang, don't talk about humiliation.

Zhuang Yi was holding two warm buns. As a former Criminal Police officer, he didn't care about his image and took a large bite.

He chewed while chatting with Zhou Cheng.

"Cases happen every day. If there aren't new ones, there's still a huge pile of cold cases. But Zhou Cheng, don't forget you're a civil Police Officer."

"Why are you asking me about cases every day? Last time, you severely humiliated our Criminal Investigation Team. Do you want to humiliate us again?"

Zhuang Yi joked casually.

To him, as long as the case could be solved, it didn't matter if he was humiliated or had his face slapped every day!

Hearing Zhuang Yi's words, Zhou Cheng laughed.

"Captain Zhuang, don't talk about humiliation. We're all serving the people."

Zhuang Yi quite agreed with Zhou Cheng's words.

He now had a faint inkling of what Zhou Cheng was thinking.

He probably had an addiction to solving cases!

Otherwise, it would be hard to explain.

After all, he had plenty of money and didn't need power!

So looking at it now, he was purely just addicted!

"Why don't you just come to our Criminal Investigation Team?" Zhuang Yi said casually.

But before Zhou Cheng could respond, Zhuang Yi quickly retracted it.

"Wait, no, the Criminal Investigation Team is too dangerous. It's not suitable for you."

Given Zhou Cheng's current high-profile status, even if he agreed to come, Zhuang Yi wouldn't dare take him.

What if he got injured while on a mission?

Zhou Cheng smiled helplessly as Zhuang Yi talked to himself.

So even if Zhou Cheng wanted to go, the Criminal Investigation Team wouldn't take him!

However, Zhou Cheng didn't plan on going anyway. Staying in the Public Security Team and helping the Criminal Investigation Team when he had time was better.

That way, he could enjoy the leisure of the Public Security Team while also solving cases to earn merits and police force value.

"There is one. If you have time at noon, why not drop by our Criminal Investigation Team?" Zhuang Yi said heartily.

"No problem," Zhou Cheng replied!

More police force value to be earned!

Afterward, Zhou Cheng chatted with Zhuang Yi for a bit longer before heading to the locker room.

After changing clothes, Zhou Cheng walked to his own brigade!

"Captain Zhou."

"Good morning, Captain Zhou."

Zhou Cheng's appointment had come through last week, and on Sunday, he had already treated his team members to a meal.

It was arranged at the Haosheng Hotel again, making the team members exclaim how generous Zhou Cheng was.

They even asked Captain Wu several times if this violated any discipline before they felt at ease.

So now that he was at the police station, everyone's way of addressing Zhou Cheng had changed!

Zhou Cheng nodded as everyone greeted him.

Although he was only a deputy brigade captain, he was still a captain!

Zhao Yier had arrived at the station long ago. When she saw Zhou Cheng, she immediately approached him.

"Brother Zhou Cheng, did you take leave yesterday to go to the Ye Group?"

"Why didn't you arrest anyone?"

Zhao Yier had been following Zhou Cheng's news. She had seen the reports related to the Ye Group yesterday!

Hearing this, Zhou Cheng glanced at Zhao Yier.

Why was she just like He Yubing, asking why he didn't arrest anyone?

Was he the kind of person who arrested people at the drop of a hat?

"I'll arrest them another day!" Zhou Cheng replied.

"Oh, okay! I'll help you claim the credit then!" Zhao Yier said!

"Sure. But, Little Zhao..."

"Present!"

"..."

"Can you stop calling me 'Brother Zhou Cheng'? It sounds like 'Brother Bearing' to me..."

"Oh, then what should I call you? Captain Zhou? My dad always tells me to use official titles at work."

"Exactly. You're a Genius, Private Zhao!"

...In the morning, Zhou Cheng went out on a call!

He mediated a divorce case between an elderly couple.

The old man always felt that his grandson didn't look like him. Especially when he took the grandson out to play chess with other old men in the neighborhood, they often said the boy didn't resemble him.

Because of this, the old man was in a bad mood every day!

He had lost his temper at home several times.

This time, the daughter-in-law couldn't take it anymore and dragged the whole family to get a paternity test.

Afterward, the old man also took the test on a whim. The result showed that the grandson was indeed his son's biological child.

But he and his son actually had no blood relation.

The old man fainted in the hospital. After returning, he threatened to jump off a building and demanded a divorce!

Zhou Cheng didn't have much to mediate; he had no intention of persuading them to reconcile.

As a Police Officer, he could only protect the old man and prevent him from jumping.

Then he enjoyed the drama!

He couldn't help but marvel at how ruthless the old lady was!

After returning, Zhou Cheng thought about it carefully—wasn't this the Hou Guifen plot?

Had this been integrated too?

At noon, Zhou Cheng went to the Criminal Investigation Team. This time, the Police Officers no longer looked at him with disdain!

Some even greeted him specifically when they saw him!

After finding Zhuang Yi, Zhou Cheng asked him about the current case.

"The one I need your help with is a cold case!"

Zhuang Yi led Zhou Cheng to the meeting room and had a Police Officer bring over a case file!

Seeing this, Zhou Cheng didn't hesitate.

He picked up the file and started flipping through it!

"This case was the first one I took on when I was promoted to Captain of the Criminal Investigation Brigade. You know, when you're first promoted, you're full of ambition. But it was this very case that gave me my first failure right after my promotion!"

"Therefore, even now that I've been promoted to detachment captain of the Criminal Investigation Detachment, I still look for new leads every year to solve this case!"

Zhuang Yi looked at Zhou Cheng and spoke slowly.

He recounted the origin of the case.

For many Criminal Police officers, solving cases is their daily life. Cases that couldn't be solved at the time become a knot in their hearts!

As long as it remains unsolved, they will remember it every day!

This has led to many classic examples of chasing a killer for years and finally catching them to solve the case!

And this case was the knot in Zhuang Yi's heart!

"Captain Zhuang, although Zhou Cheng is indeed very capable, isn't bringing out this case just making things difficult for him?"

The brigade captain following Zhuang Yi said casually. This was a long-standing cold case. Unless new leads were found, the investigation wouldn't even be reopened!

And the fact that it had become a cold case meant the killer was extremely difficult to catch!

"It's fine. This morning, Zhou Cheng happened to ask if there were any cases, so I thought of this one. It doesn't matter if it can't be solved," Zhuang Yi replied.

In truth, Zhuang Yi didn't have high expectations for Zhou Cheng.

This case was simply too old! It was hard to solve back then, let alone now!

It was just a lingering obsession; he hoped he might hear a new approach from Zhou Cheng!

He really didn't want the killer to remain at large!

"It was ten years ago! Surveillance wasn't well-developed then, especially in cluttered areas! The killer took advantage of this to commit four murders!"

"According to the investigation at the time, the killer's motive was purely money! All the money in those homes had been looted!"

"The killer specifically chose areas with little surveillance. Once he confirmed the adults weren't home, he would disguise himself as a water meter reader to knock on the door. After entering, he would act immediately, killing the children and elderly in the house!"

Listening to Zhuang Yi, Zhou Cheng nodded silently.

Meanwhile, the speed at which he flipped through the file didn't slow down.

"Captain Zhuang, during the investigation back then, there must have been an inquiry into the neighbors around the crime scenes, right? Some neighbors must have seen the killer's face. Are the transcripts of their descriptions of the killer's appearance in here?" Zhou Cheng asked.

This was the key to solving the case!

"They're in this file," Zhuang Yi replied after hearing Zhou Cheng's question!

"Alright. Oh, and get me a piece of sketch paper and a pencil," Zhou Cheng added!
