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

...

Meng Yang lay in a hospital bed, but the investigation of the case did not stop; Captain Zhao and Lao Wu were still sorting out clues.

"Captain Zhao, I've found an important clue!" Xiao Song excitedly rushed into the conference room, holding an evidence bag in his hand.

The evidence bag contained a dagger.

Team Leader Zhao and Lao Wu looked up.

"Is this the dagger on Meng Yang's back?" Captain Zhao asked.

"Yes." Xiao Song couldn't hide his excitement, "But guess what? I found several people's bloodstains on it."

Xiao Song held up three fingers.

"Three! Three people's bloodstains."

Wow, so many? Don't you even wash them after using them?

Washing with water sometimes doesn't work, but if someone really wanted to, they wouldn't leave a trace. I guess the culprit was either in a rush or did it intentionally.

[Besides Meng Yang, there's probably that girl too. Who's the other one?]

...

"Three people? That's a lot." Old Wu exclaimed in surprise.

"Yes, all the cases are connected."

Xiao Song excitedly walked to the blackboard and pointed to the photo of Meng Yang and the girl.

"I just compared them. There is Xiaoli's blood on this knife, and the blade matches the wound on Xiaoli's neck perfectly. So this knife is the murder weapon that killed Xiaoli."

Team Leader Zhao: "So, in terms of the sequence of events, the knife killed Xiaoli first, and then slit her neck?"

"Yes, that's exactly what I mean. So Xiaoli died first, and then Mengyang was injured. If it's a locked room, then Mengyang is definitely the murderer!" Xiao Song said excitedly, and couldn't help but wave his fist.

[If it were Liang Jiahui, wouldn't that also explain why he killed Xiaoli first and then stabbed Meng Yang in the back? That would also make sense.]

No, if Liang Jiahui did it, how did he lock the door from the inside? Unless they can crack this secret room, Meng Yang is definitely the murderer, and he can't wash his hands of it.

I just checked into a room; it was one of those old-fashioned chain locks. I tried Conan's method, but it's impossible.

So, based on the current reasoning, Meng Yang was the murderer, right?

But why would he stab himself in the back?

"The only answer is to ask him."

...

Upon hearing Xiao Song's analysis, Team Leader Zhao and Lao Wu couldn't help but pump their fists.

After two rounds, we finally managed to catch Meng Yang. It was so difficult.

After the initial excitement, Captain Zhao suddenly frowned.

"That's not right. If Meng Yang killed him, he could have escaped. Why would he stab himself, especially in the back?"

Before Lao Wu could speak, Xiao Song interrupted him.

"I've thought about this, and this is my guess. Meng Yang's crime this time was very likely a crime of passion. It would be difficult to erase all traces at the scene, so he only had one way: to create the illusion that he was attacked."

So he put the knife on the ground, or clipped it somewhere, and then leaned his back against it.

[I feel like I've heard this technique mentioned before.]

[It's seen in Detective Conan, and it's also used in Hong Kong dramas; people use self-harm to dispel police suspicion.]

Self-harm is fine, but why lock yourself in? It's completely unnecessary.

[The reason he did this is because if Meng Yang had self-harmed, there would be no need to lock the door; it would be redundant. A normal person would assume he was stabbed and then created the locked room.]

[Holy crap! What am I listening to?]

To sum it up in one sentence: I predicted your predictions, and your predictions, and now you can go through the motions yourself.

Damn, these guys, they're so cunning even when they're just killing someone.

...

"Then, to avoid making us suspect that he had harmed himself, he deliberately created a secret room to make us think that a third person was present. But he forgot."

Xiao Song became more and more excited as he spoke.

"He forgot about the lock and couldn't lock it from the outside at all."

After saying that, Xiao Song looked expectantly at Team Leader Zhao and Lao Wu.

Zhao tapped his fingers lightly on the table, then turned to look at Lao Wu.

Old Wu nodded.

"I think it's reasonable."

"I think that's reasonable, but there needs to be supporting evidence."

Old Wu stood up.

"I'll go to the lab now and look for it. If we can find the marks where the dagger was caught, it will prove that the dagger was indeed caught on it and Meng Yang leaned against it himself."

"Wait a minute!" Xiao Song suddenly called out to Lao Wu, "I haven't mentioned the third person's bloodstains yet."

Old Wu then remembered that there were three people's bloodstains.

"Then you tell me."

Xiao Song smugly raised the dagger and moved it in front of a photograph.

"Ren Haifeng, we found Ren Haifeng's blood on this dagger."

"What?!"

At this point, both Captain Zhao and Lao Wu couldn't sit still any longer and stood up, their eyes gleaming with excitement.

Are you serious?

"Of course it's true, how could it be false?" Xiao Song nodded.

"Therefore, I think Meng Yang was most likely the one who killed Ren Haifeng, because Lao Wu only found Meng Yang's fingerprints on this dagger."

Old Wu nodded in confirmation.

"This dagger only has Meng Yang's fingerprints, and it also has Ren Haifeng's blood and Xiao Li's blood. So Meng Yang really could be the killer from that rainy night."

Team Leader Zhao started muttering.

"When I watched the surveillance footage that night, I thought that person's figure was rather tall. It seems that Meng Yang used some tricks again."

Xiao Song: "Captain Zhao, now we just need to wait for Lao Wu to go to the scene. As long as we can find traces of the dagger being stuck there, then Meng Yang is definitely not going to escape."

Old Wu got up.

"I'll go now, wait for me, it'll be quick."

Old Wu left quickly and returned quickly.

"Found it." Upon returning, even the usually composed Old Wu couldn't hide his excitement.

He took out several photos and pasted them on the blackboard.

"Look, these are the cabinets in the lab. They're taller than a person when stacked up, and they're here."

Old Wu pointed to the space between two cabinets and then took out an enlarged photograph.

"I saw some scratches here, and there was some residue on them. I just compared them, and it's the dagger."

"Good!" Captain Zhao punched the air hard. "Let's see what Meng Yang has to say now."

[Damn it, it seems the chain of evidence is complete.]

It seems Liang Jiahui didn't make a move this time.

Could it be that Meng Yang also killed Ren Haifeng?

[That shouldn't be the case. If Meng Yang had killed him, there would have been no need to ask so many questions, including who he had a grudge against. He should have just gone up and killed him with a single blow.]

[Yeah, but was Liang Jiahui actually at the scene? And what's with this knife? I'm getting more and more confused.]

Let's wait and see what Meng Yang says when he wakes up.

[Ugh, that's the downside of this show. Until the very last moment, damn it, you have no idea what's real and what's fake. It leaves me completely confused.]

"Isn't that great? Are you suggesting we watch celebrities sitting there chatting, complaining about how tough their lives are, or how they make hundreds of thousands a day? Pshaw."

[Mind-bending, I love watching mind-bending shows.]

The internet is in an uproar right now, and they even held a poll where people were split on whether there was a third person involved or not, with both sides having their own reasons.

Sigh, I hope Meng Yang wakes up soon, otherwise this will remain an unsolved mystery.

If Meng Yang doesn't wake up soon, Lu Fei will be crying her eyes out.

Yes, it seems she's been sitting right outside the ward the whole time, just sitting there. Ah, it's truly heartbreaking to see her like that.

...

August 31th, the tenth day.

Lu Fei opened her eyes wearily; she had been keeping watch all night.

Even though she wasn't allowed to go in, she just wanted to stay there for peace of mind.

Around 8 a.m., Meng Yang woke up, and the trio rushed over.
