Investigation

The entire room was silent, everyone busy with their own tasks, until Liang An opened the door and walked in.
"Why is the atmosphere like a funeral?" Liang An looked around, confirming that there were indeed people sitting in the air-conditioned room. "What? Not going smoothly?"
Lu Yao turned her head to look, the computer screen light still illuminating her profile, witnessing this always confident and brilliant young woman sigh in frustration.
"What kind of girl is this, leaving no information at all. I've never seen such a difficult group of scammers; are 'green tea' techniques so advanced now? I thought it was just piercing a few layers of basic assumptions."
"Is there no way?" Jiang Qiu, sitting next to her, blinked.
Lu Yao was clearly not one to give up easily, but she still shook her head.
"Clearly, the other party was prepared early... I see, this shouldn't really be a coincidence."
Liang An also pulled over an office chair, sitting to one side, looking at the incomprehensible data streams and serial numbers on the screen, and couldn't help but feel that this case was one in a thousand years, a bit amusing: "Didn't I say? This kind of coincidence basically cannot exist, and the chat messages were too deliberate. The other party couldn't have been unprepared."
Lu Yao said resentfully: "If I could push him to a dead end, make him temporarily show up and give me a flaw, then even if Morning Star really did a good deed, at least in this field, he couldn't surpass me."
Just as Lu Yao said, their speculation wasn't just casual mockery of Du Xiao Si being deceived.
But it was a matter with a cause.
If it were truly just an ordinary scammer, it wouldn't be possible for Shao Zi to personally go through so much polite talk, even devising so many schemes just to gradually break down Du Mao's psychological defenses and get to the question that caught him off guard.
In fact, Shao Zi's original understanding of Du Mao's grateful situation ended after receiving the initial inquiry information.
All three police teams had looked into Du Mao's file; he was indeed unlikely to have access to internal intelligence, even like the small gang leader who was interrogated and provided crucial information that helped the three police teams save the little girl. No matter how agile Du Mao was, he was an outsider to the syndicate, not an insider. If important information could be known to him, then all the information of the criminal syndicate would probably have long been exposed to the internal informant Old Yang.
As for whether Du Mao might have been involved with some small grassroots leaders or even HR personnel, that was not within the scope of senior consideration. Perhaps Du Mao could have caused trouble several times without being truly driven away, also because he was indeed naturally strong, and someone felt he might be useful later, but this didn't mean his clean record understood the inside story.
The official re-interrogation of Du Mao himself was because of the "girl" named "Xiao Xing He."
The suspicion about this "girl's" identity wasn't just because her name and portrait seemed to be an effort to hook Du Mao, nor was it because she, based on her middle school education and nineteen years of experience, imagined an absurd company structure and personnel relationships for Du Mao, nor was her sudden mysterious disappearance a very large factor.
The most crucial reason was the recent content in her chat history with Du Mao.
【. The cargo box has a problem; the position of the sealing paper was tampered with last night.
. There are many black marks on the wall → someone climbed the wall to peek.
. There's a camera signal nearby. 】
These were the three clues Du Mao believed to be reliable, used to prove his conclusion about an internal informant. These clues all originated from Du Mao himself, stemming from his interest and curiosity about the villain he idolized, but in reality, this curiosity had another reason.
Undoubtedly, Du Mao's investigative methods were crude and blatant. The information he observed was more like the "spot the difference" web games popular decades ago, with different versions but still revolving around one point.
Although it's not pleasant to say, Du Mao currently indeed regarded this kind of "spot the difference" as a very formal investigative process. Although everyone said this child had a mental illness, based on Shao Zi's observations, he indeed thought that his parents or relatives should find a psychologist for him, but at least on the intelligence issue, Du Mao didn't seem to be truly lacking a few screws.
Just like that, a very blatant problem appeared in the puzzle of truth—why would Du Mao be so certain about this method of investigation?
The sealing paper on the cargo box might not have been properly sealed at all, easily coming loose and shifting with a gust of wind. The black marks on the wall could also be from a passerby's casual kick; a young, wild person like Du Mao couldn't possibly be unaware of walls that had been indiscriminately kicked, even having kicked white walls himself as a child, finding it amusing.
As for the camera, that was even more baseless talk. It was perfectly normal for Li Chun Sheng, as a gang leader, to want to equip cameras near his room to ensure safety. Moreover, if someone was truly secretly peeking, how could they clearly not even change the camera's name, using such a simple method to be discovered?
The most important thing, of course, was Old Yang's statement that he hadn't done anything. But these suspicious points still generated the most widespread doubt in one place, and to explain this point, it was necessary to start from Du Mao himself.
Who could influence him to generate such illogical suspicions, to believe these superficial, unexamined clues? Who would make him believe this without doubt, feeling that he had found the truth through his own abilities?
Du Mao might have had some overconfidence in social interactions online; after all, being able to chat with the girl he admired for several hours every day was indeed not normal. But in reality, in everyone's eyes, he was a silent, eccentric person. Let alone whether a disliked person could influence his thinking, even Old Yang, who had some sympathy and goodwill towards him, had never truly spoken much with Du Mao.
As for Li Chun Sheng, whom Du Mao idolized, Du Mao clearly regarded this boss as a kind of idolized figure, but this adoration was only like children playing with bubbles; currently, it wasn't even very persistent, probably forgotten after a few days back to normal life.
Thus, only one person remained.
That mysterious "Xiao Xing He."
Utilizing all the material factors against Du Mao, who hadn't deeply entered society, to conduct "targeted attacks," always replying to his messages instantly for several days, then suddenly losing contact on the same day the police launched their operation. What was even more profound was that Li Chun Sheng had indeed prepared to leave on the same day.
Assuming he truly hadn't died, packed his bags and left, perhaps Team Two's investigation would have come up empty, allowing the main culprit to escape justice freely.
It was just that everything was thoroughly mixed up by the two murders.
Undoubtedly, if someone had truly told Li Chun Sheng that there would be an operation to arrest him that night, then the problem should lie with Du Mao's online friend, on whom all coincidences converged.
This person was also the one who planted the seeds of doubt in Du Mao's mind through their chat content.
Du Mao thought he was using a facade of lies to deceive an ignorant girl, even feeling guilty about it, unaware that this "girl" was actually secretly guiding him to generate suspicion, based on Du Mao's childish character assumptions.
Transforming the concept of "internal informant in the team" into "commercial spy stealing secrets," subtly conveying this kind of information to Du Mao under the pretext of watching spy movies, and these contents were then automatically translated in Du Mao's mind, who believed he was in control of the situation, forming a completely different story.
To go through such trouble to complete this series of operations, the true target was almost certainly still the person whose crimes were written in the declaration letter.
Li Chun Sheng.
And the person who killed Li Chun Sheng, according to current speculation, was only one person.
That was Morning Star.
"Yu Ying Jian said that they decided to launch the operation that day for an important reason." Shao Zi finished dealing with the remaining issues concerning Du Mao and came out of the interrogation room. "An anonymous email sent intelligence to the police bureau's inbox, saying there was a child crying near a hideout address. Yu Ying Jian originally didn't dare to take the risk, but Old Yang also simultaneously sent news that the main personnel had gathered at the hideout, and someone would have to leave again after another day, so the mission was thus naturally set for that day."
This was indeed a moment where numerous coincidences converged.
If they were conscious coincidences, could they truly just be coincidences?
"If the organ trafficking activity was known to occur the next day, could someone have intentionally planned this operation to save that child?" Liang An raised the question. "I heard that for organ trafficking, the highest success rate requires both the buyer and the 'seller' to be present. Cold chain transportation on the black market is currently not common, because with the current situation, cash on delivery makes people feel more secure."
And that would require first setting the transaction time, which means determining the completion of the transaction, the moment an innocent child would be harmed.
This was also part of the "coincidence."
"So you mean..." When the entire room fell silent, Jiang Qiu suddenly spoke in the quietness, "Someone intentionally chose to use this timing?"
If the previous speculation was not wrong, this person's identity was self-evident.
