"Wait...you let us start, but what should we do..." Long Yechun asked.
"Monokuma doesn't care about us. He wants us to fight among ourselves and doubt each other." Bian Gushan said coldly.
"Who is the murderer? Come forward! Otherwise, he will be caught later, and I won't be polite!" Akane yelled.
"Huh...who is the murderer? Yamamoto Issuru was killed while on patrol after the party. Anyone could be it, right?" Kuzuryuu said in a strange tone.
"Huh? Kuzuryuu! What do you mean!" Izumi has always been unhappy with Kuzuryuu, so it doesn't matter that the two of them often quarrel.
"Heh... you should just continue hurting each other, it has nothing to do with me." Kuzuryuu turned his head, looking like he was watching a good show.
"Huh? You think that except you, the rest of us might be the murderers, right?" Quan said dissatisfied.
"Wait... stop arguing. How about we sort out the situation first? Lin Xiao..." Kurosaki said to Lin Xiao after dissuading the two of them.
Lin Xiao glanced at everyone: "Yamamoto-kun's death time was about 8-9, and Atorya and I were on patrol at the time. We can guarantee that no one broke into the room to kill anyone."
"That's a secret room murder!" Zuotian shouted.
"Murder in a secret room...Isn't this something that only happens inside...It's really terrifying..." Sister Sonia.
"So, have you come up with any results?" Hoshino Qiu asked.
Because he lost his best friend, he seemed to have not slept, his eyes were red and his mental state was very bad.
"The secret room murder, as long as the mystery of the secret room is solved, it will probably be solved easily..." Hinata Chuang.
"Yes...it's just because I don't know the method, but I also made a guess." Lin Xiao.
"What method is it?" Xiyuanji asked impatiently.
"It's very simple. After our party, we went back to the room 7 times, and during this interval, the murderer sneaked into Yamamoto-san's room and killed him.
Then he fled back to the room and pretended not to know anything." Lin Xiao.
"Everyone, I don't know what you did after you went back to your room." Artoria said.
Sinmu: "...Well...I, Quan, Xiyuanji and I went outside the hotel to enjoy the wind, and then went back."
Quan: "The three of us can testify to each other."
Xiyuanji: "Hmph. It seems that after going out with this stupid pig like Sinmu for a while, I have an alibi."
Sinmu said weakly: "It's too much..."
Saionji: "Tsk. Just be grateful..."
Wei Chui: "Actually, I also saw the three of them when I was on my way to the city."
Kurosaki: Didn’t the party just end, and you went to the market again?
Wei Chui laughed and said, "There's nothing I can do about it, my 13 stomachs can't be filled no matter what."
After that, everyone knew the whereabouts of 7-8 one by one. Except for the four of them, the others were resting in the room.
Judging from everyone's behavior, it was impossible to tell who would take this opportunity to kill Yamamoto.
After a period of debate, things seemed to be getting harder and harder to clear up.
The atmosphere among everyone was getting worse and worse. Lin Xiao realized that something was wrong and immediately changed the topic and said: "Since everyone is in the room at this time, let me come and ask a question that I still can't figure out."
"What question?" Hinata asked.
"Yamamoto's autopsy report shows that he was tied up and severely beaten, so I speculate that he was in the room, was attacked by someone, knocked unconscious, tied up in the room, and then injected with chemical poison and died.
"Lin Xiao.
"But? Is there anything strange about this?" Nanami Chiaki asked.
"Because the murderer's actions were superfluous," Komaeda explained. "It was entirely possible to just use poison to kill Yamamoto-san directly. Why did he make two openings after being tied up, causing a large amount of blood at the scene?"
Yoshida: "The murderer may have a grudge against Yamamoto-san and wants to torture him."
Artoria: "If you torture me, you should have more wounds. Instead, it seems like you are hiding something."
Long Yechun: "Is it to hide the wound where poison was injected?"
Sonia: "If you think about it this way, it is indeed very possible."
Wei Chui: Could it be that the prisoner was unable to torture because time was too tight?
Lin Xiao fell into thinking and felt something was wrong. The prisoner was indeed unnecessary. What was he hiding?
At this time, Lin Xiao remembered the situation at the scene and then expressed his own opinions.
"The prisoner actually didn't do it to hide anything, but did it deliberately." Lin Xiao.
"What is the purpose of doing this deliberately?" Hyuga Sou wondered.
"It's a very simple reason. It makes the entire murder scene even more chaotic." Lin Xiao.
"What benefits does this do to the prisoner?" Sonia.
"Could it be to hide his secret room?" Kurosaki said eagerly with a sharp light flashing in his eyes.
"Hiding his secret room? What does this mean?" Zuotian was confused.
"Yes, I have read a lot of mysteries, and there are introductions to the secret room killing technique, and one of them is a fake secret room."
Kurosaki paused and explained: "The so-called fake secret room, for example, has a secret passage in the room that can enter and exit the victim's room, or it is deliberately creating chaos. In fact, the murderer is hiding in the room..."
"Although it is a secret killing, it should be different from the fake secret room. I went in with Lin Xiao and Hoshino, so I can confirm that there are no problems in the room."
Atria thought for a moment.
Hoshino Akira: "How did the prisoner get in and out of Fifteen's room freely? Lin Xiao and Artoria were obviously guarding...
This is the most important puzzle, right? Shi Fifteen was already dead when we entered...the time of death doesn't match up at all."
These words caused the audience to fall into silence. This is where Lin Xiao is most confused.
"I also like Japanese culture very much, and I have also read the mystery, which contains a secret room killing method with a time difference." Sonia said suddenly.
"What kind of killing method was that?" Zhongli shouted.
"The so-called time difference killing method is to use the clock to mess up." Sonia.
"Wait...you messed up the clock? But there seems to be nothing wrong with the clock..." Nanami.
"No, this demon king has seen someone who is doing evil!" Tanaka suddenly said this for no reason.
"Hey! At this time, you are not serious yet!" Quan said angrily.
"It's you, Komaeda!" Tanaka pointed at Komaeda and said in shock.
Komaeda laughed: "Oh...it seems like I was discovered."
