A perfect crime? To me, it's full of flaws!

The task force's large office was filled with smoke.

Inside the innermost glass compartment, Guan Hai was pointing at the map on the wall, repeatedly discussing the details of tonight's patrol and deployment with several trusted lieutenants.

Just then, there were two knocks on the door.

Before anyone inside could respond, the door was pushed open, and Qi Feng walked in carrying a freshly printed document.

When Guan Hai saw Qi Feng enter, his brows furrowed almost imperceptibly.

What's this kid up to now?

In the past few days, Qi Feng had been busy installing a refrigerator and buying snacks in his office, never leaving the premises. Guan Hai didn't think there was anything wrong with that; he was happy to have some peace and quiet.

In his view, these young people sent down by the provincial government to gain experience are the greatest help they can provide, as long as they don't cause trouble.

The case is solved, so we'll add a note to his record. It'll be a win-win situation for everyone.

But why is he getting involved at this crucial moment?

A hint of displeasure flashed through Guan Hai's mind, but he didn't show it much on his face.

After all, they were people from the provincial department, so we had to put on a good show.

"Comrade Qi Feng, you've come at the perfect time. We're just discussing tonight's patrol plan. Would you like to sit down and listen in?"

Although the words were polite, the subtext was all too clear: This is our core meeting. You can listen in, but don't interrupt or cause trouble.

Qi Feng seemed completely oblivious to his implied meaning, shook his head, and simply raised the document in his hand.

"Captain Guan, I'm not here to hear the plan."

"I've made some new discoveries."

Upon hearing this, Guan Hai's smile vanished instantly.

New discovery?

His dozens of elites have been working non-stop for so many days, and even after working themselves to the bone, they still haven't found a breakthrough.

You're just a 24-year-old greenhorn who's been eating snacks and drinking cases of cola in the office for a few days and suddenly you've made a new discovery?

And he deliberately chose this time, barging in with a document, making it seem like something earth-shattering had happened.

Are you here to help or to cause trouble? Show off your true colors!

Suppressing his anger, Guan Hai forced out a sentence through gritted teeth, his contempt undisguised: "Oh? Is that so? That's perfect. Tell us, let's hear what amazing insights the experts from the provincial department have."

The other veteran detectives in the meeting room all focused their attention on Qi Feng, each with a different expression.

There was curiosity, there was scrutiny, but more than anything, there was skepticism, just like Guan Hai's.

They've all seen the commotion Qi Feng has been causing in the office these past few days.

They don't seem to be here to investigate a case; they seem more like they're here for a vacation.

Qi Feng didn't pay attention to this situation and started to tell the story from the beginning.

The common thread among these six individuals was that they were all orphans.

Then he went to these six orphanages and found these six people. The time when they entered the orphanages was surprisingly consistent, all in September 2003.

Upon hearing Qi Feng's words, the expressions of the people in the room changed, and they began to take it seriously, even sitting up straighter. This kid seems to really have some talent!

Next, Qi Feng began to recount how he discovered the black disc, and how he found it in the cars of all six victims!

The people in the room were even more surprised. If the previous six people were all orphans and entered the orphanage at roughly the same time, it could be called a coincidence.

Then this black disc is the evidence!

Qi Feng paused, cleared his throat, and began to explain the most important part, namely the composition and function of the black circular material.

After listening to Qi Feng's explanation, the people in the room could no longer sit still.

This... this means we've found the criminal's modus operandi! This is a huge breakthrough!

At this moment, Guan Hai also changed his impression of Qi Feng.

After Qi Feng finished explaining, he didn't continue speaking, but instead looked at Guan Hai.

Guan Hai thought for a moment, then said.

"Now we should investigate along the lines of the black, round medicinal herbs. Also, we need to find out where these six victims came from before they entered the orphanage."

"Yes, the main medicinal materials investigated are two kinds: Polygonum multiflorum and Acorus tatarinowii. These two medicinal materials are not very common, and few people know their effects. As for investigating the experiences of the six victims before they entered the orphanage, we will have to investigate slowly."

Qi Feng now feels that investigating the medicinal herbs is more reliable. The experiences of the six victims, more than 20 years ago, are too time-consuming to investigate, and there is a high possibility that nothing will be found.

"Okay, I'll have someone investigate this later. Everyone needs to stay alert tonight; we can't afford any more deaths."

After thinking it over, Guan Hai decided to focus on completing tonight's operation first. As for the investigation, it would have to wait until no one died tonight, since it was time to start again.

Qi Feng felt that Guan Hai's words made sense. Investigating what Guan Hai said was not the most urgent task at present. Preventing more deaths was the most important thing.

And then came Qi Feng's investigation results.

Tonight, the criminal investigation team has prepared something different.
