You're cast as a villain, and you're supposed to teach the police how to solve cases?

...

March 29th, the eighth day.

Since Yang Lin is not considered a suspect, the only option is to call him over to assist with the investigation.

Upon seeing the police, Yang Lin's attitude was not good; his expression showed some resistance.

"Officers, what's the point of you bringing me here to ask questions instead of investigating my daughter's case?"

"Yang Lin," Captain Zhao said, looking at him, "we've come here to learn some things that might be related to your daughter's death."

Upon hearing that it was related to his daughter's death, Yang Lin immediately sat up straight.

"Okay, tell me, what did you find out?"

Team Leader Zhao handed over Chen Sanfu's photo.

Have you seen this person before?

Yang Lin took it and examined it carefully, then calmly said,

"I don't know him, but I do know him. He's an old conman who sneaks around on campus and preys on female students."

Team Leader Zhao was somewhat surprised. "How do you know he's a fraud?"

Yang Lin curled his lip in disdain.

"Only those young girls wouldn't know; who wouldn't notice?"

After speaking, he paused, then looked at Captain Zhao.

"You don't think he's involved in my daughter's death, do you?"

"Yes!" Captain Zhao answered affirmatively, "We think Xiaorou might have been deceived by him."

Hearing this, Yang Lin laughed.

"I don't know what you police are doing, thinking that way. I can tell you very clearly, Xiaorou's man is not this old liar."

As he spoke, Yang Lin took out a piece of paper from his pocket, on which were written a few neat characters.

"Look, Xiaorou wrote this herself."

Team Leader Zhao took it and looked at it. He saw where the paper had been torn from, and there were only a few lines of writing on it.

Although he's older, he's very knowledgeable and treats us very well. I admire him a lot. But I think I might be pregnant, and he has a wife. What should I do?

Behind the words, there was a small figure drawn, which could only be identified as a man, with no facial features depicted at all.

"Is this Xiaorou's handwriting?"

"Yes, I found this in her schoolbag, so the man behind her is a learned, married older man whom I often see, this Chen Sanfu."

Yang Lin tapped the table.

"He looks like an ordinary worker. His academic background doesn't match what my daughter wrote on the paper. It can't be him."

Team Leader Zhao never expected that Yang Lin would have such a clue.

"Yang Lin, you need to provide any leads to the police as soon as possible. It's not very useful for you to keep them to yourself," Captain Zhao reminded him.

"Do you think it'll be useful just because I gave it to you?" Yang Lin said dismissively.

Faced with Yang Lin's sarcasm, Captain Zhao didn't know what to say, only that the recent cases had been a bit strange.

"Yang Lin, where were you between 9 PM and 10 PM on March 26th?"

Anyway, since we're already here, we should definitely ask.

"Still doubting me, huh?" Yang Lin chuckled. "Let me think about it."

"On the evening of March 26th, which should have been the day before yesterday, I was in the principal's office that night. I asked him to provide me with the surveillance footage of Xiaorou at school, but he refused. So I waited for him in the office until almost 11 o'clock before leaving."

[Remembering it so clearly, it must have been prepared in advance.]

"Brother, they waited all night, they remember exactly what the problem was. Besides, the principal is a witness, the principal couldn't possibly be in cahoots with him, could he?"

Yes, the principal is neutral. Since he can say he was with the principal, his suspicion can basically be ruled out.

[If it wasn't Ren Haifeng who killed him, and it wasn't Yang Lin who killed him, then who could it be?]

Why think so much? I'll just blindly guess it's Meng Yang; there's at least an 80% chance it's him.

Meng Yang doesn't have time; we all saw that.

"Tch, we saw him transport the body there last time too. In the end, I just don't trust my eyes, I trust my intuition."

That makes sense.

...

Team Leader Zhao noted it down. If what Yang Lin said was true, then he couldn't possibly be the murderer.

Of course, it needs to be verified.

After releasing Yang Lin, Captain Zhao went straight to the school and found the principal.

The principal had visibly aged and looked haggard lately. Upon seeing Captain Zhao, his eyelids twitched violently, and he asked nervously,

"Captain Zhao, has something happened again?"

"Oh, no."

"That's good, that's good." The principal patted his chest, feeling as relieved as if he had just finished defecating due to constipation.

"So, Captain Zhao, you've come to see me?"

"Oh, I'd like to know something." Captain Zhao sat down. "Was Yang Lin with you between 9 and 10 pm on the night of March 26th?"

Mentioning Yang Lin, the principal looked constipated.

"Yes! He blocked me in the office and wouldn't let me leave. He insisted on watching the surveillance footage of his daughter. I explained to him that he couldn't access the footage on his own, but he just wouldn't listen."

"Captain Zhao, I think you guys need to keep a close eye on Yang Lin. He always thinks he's some kind of super detective. And Xiao Rou is dead, and it was suicide. What is he trying to do?"

As he spoke, the principal couldn't help but scratch his sparse hair and pull out a few more strands.

The principal is heartbroken; someone's child died and he has to pay compensation. He just wants to find out the truth.

Students these days are hard to manage; they all have their own ideas, and some even rent apartments off-campus. How can he possibly control them?

However, this confirms Yang Lin's words; at least it wasn't Yang Lin who killed Qin Wei.

[So who exactly is this hidden character? The production team really hasn't given us any information at all. We don't even know if they've been activated yet.]

Damn, watching this show makes me feel like I'm losing millions of brain cells every day.

...

"Do you remember what time he left?"

"I remember! It was around 11 o'clock, already dark," the principal began to complain.

"Captain Zhao, wouldn't this be considered disorderly conduct? Should we lock him up for a few days? I can't take it anymore."

"We will educate him, don't worry."

Team Leader Zhao closed his notebook. With the principal's testimony, Yang Lin's suspicion was also cleared.

However, there are some things he still needs the principal's cooperation with.

He took out Chen Sanfu's photo.

"Principal, do you know this person?"

Upon seeing Chen Sanfu's photo, the principal's expression froze, and his reaction was somewhat strange.

"I know this person, but I don't think he's from our school."

"Yes, he's not from your school, but he often comes to your school, pretending to be from the National Security Bureau to deceive female students. Are you aware of this?"

The principal was somewhat surprised.

"Oh, he's a fraud. I didn't know. Don't worry, I'll give his picture to security right away, and next time they won't let him in."

Team Leader Zhao put the photos away.

"There's no need for that, he's already dead."

"Dead!" the principal exclaimed, jumping up from his seat, his face filled with disbelief.

"I saw him and Lu Fei strolling around campus just a few days ago."
