"Can't we just go out through that sliding door and go directly to the corridor?"

Xiaofeng: "No, it's impossible to get in and out through that sliding door."

"Tell me, am I having an affair, you ugly girl?" said the beautiful rabbit.

"what are you talking about."

"Because the sliding door of the audio-visual room is out of order, it can only be opened a little." Xiaofeng said.

"Only one hand can pass through at most, so it's impossible to get in and out from there."

Lin Xiao said: "There are no signs of the sliding door being forced open, and the track is covered with dust."

"In other words, the possibility of entering or exiting through that sliding door is zero?" Ryoma said.

"I see, it's really strange that this lady can make mistakes..." said the beautiful rabbit.

"It's not unusual for you to make mistakes. Besides, as an immigrant, you are a mistake in every aspect." Xiao Ji said.

"Okay, that's too much." Meitu said.

"But since that sliding door cannot be used, if Quan Tai wants to go to the library." Zhen Gong said.

"We had to pass the game room where we were, but we didn't see Chun Tai." Momota said.

"See, so Quan Tai is not the murderer." Quan Tai said.

Maid: "No, I can't say that yet. I'm sorry, Quan Tai, I don't mean to force you.

But since I said I would give my full assistance, I must fulfill my responsibilities."

"What do you mean, is it possible that Quan Tai is the murderer?" Xiao Feng said.

"What if Quan Tai-san stays in the audio-visual room and kills Tian Hai-san in the library?" the maid asked.

"Kill Tianhai in the audio-visual room?" Ryoma said.

"Oh, there is another way." An Qi said.

"Yes, and as long as you use this method, you can not only kill Tianhai in the audio-visual room."

The maid said: "It won't be caught by the cameras set up in the library."

"It's perfect, so what can I do?" Rotor said.

"Although I, the beautiful and talented lady, have known it for a long time, you should explain it to the other minions," said the beautiful rabbit.

"Before explaining this method, let's reorganize the location of the audio-visual and library."

"The sliding door of the audio-visual room where Quan Tai is located is right opposite the back door of the library, right?" the maid said.

"The position of these two doors could put Quan Tai in the audio-visual room, or kill Tian Hai in the library."

"Well, I don't understand. What should I do?" An Qi said.

"The back door of the library must be opened beforehand," the maid said.

"Wait a minute, this seems impossible at first, because didn't I just say that the sliding door of the audio-visual room cannot be opened, so I can't walk to the corridor?" Bai Yin said.

"How can we open the back door of the library if we can't reach the corridor?" Ji Wang said.

"That sliding door shouldn't be completely unopenable, but should be able to be opened wide enough for one hand to pass through, right?"

The maid said: "This way, I can easily sit down by using something in the audio-visual room."

"You're right, it could be a projection screen."

Xiaofeng said.

"That's right, as long as the projection screen in the audio-visual room is rolled up, it can be used as a slender rod."

Maid: "You can use this to open the library door."

"Put the rolled-up projection screen through the opening of the sliding door, and then use it to open the sliding door of the library."

"Of course, the projection screen should also have a certain weight, but it should be fine with the strength of Jeon Tae-san, right?"

"Well, it should be no problem." Quan Tai said.

"Ah, such an honest admission."

"But as long as you open the library door, won't you be caught by the camera?" Meng Ye said.

"The camera is placed further inside, so it won't be photographed just by opening the door," Lin Xiao said.

"This is what you took, Lin Xiao." Zhen Gong said; "The shutter was pressed after the person at the front stepped through the door."

"We already know how to open the library door, but so what." Momota said.

"Quan Tai can't leave the audio-visual room, or can't he kill Tian Hai in the library?"

"I told you that Quan Tai didn't go over to kill anyone. Instead, he stayed in the audio-visual room and killed Tian Hai in the library," the maid said.

Staying in the audio-visual and killing classmate Tianhai in the library, this represents.

"Could it be that he threw the shot put as the murder weapon?" Xiao Feng said.

"Well, please wait a moment. Isn't it a bit unscientific to actually throw the shot put? Well, if you think about it carefully, it makes sense. After all, it is a shot put." Rotor said.

"Yes, the shot put used as the murder weapon was originally used for throwing," the maid said.

Ji Wang said: "And even if someone can't pass through the gap, the shot put can pass."

"And Tianhai-san's body is exactly in a straight line with the door of the audio-visual room." the maid said.

"That is to say, as long as the back door of the library is opened and a shot put is thrown, the victim may be hit."

"But it seems to be quite a distance." Ryoma said.

"And that shot put looks very heavy." Xiao Feng said.

"Have you forgotten? Quanta-san has the arm strength to easily pick up heavy manhole covers," the maid said.

"If it was him, he might have hit the victim with a shot put from this distance, right?" the maid said.

"Let's not talk about a certain robot that is specially treated as waste. Quan Tai should be able to do it." Xiao Ji said.

"The robot that specializes in trash can't be talking about me, right? I can clean, not trash." Ji Wang said.

"So, what about, Quan Tai, can you throw the shot put such a long distance?" Rotor said.

"It should be possible." Quan Tai said.

"I honestly admitted it again." Bai Yin said.

"Wow haha, Quan Tai is so good. It's no problem to become a super high school shot put player." An Qi said.

"Then the murderer must be Quan Tai." Meitu said.

"Wait a minute, Quan Tai won't hurt anyone. After all, Quan Tai hasn't even killed an insect." Quan Tai said.

"It's true, gentlemen don't lie!"

"That's what he said, what should we do?" Ryoma said.

"Although I really want to believe it, there is no basis for it." Zhen Gong said.

If you make a mistake here, you won't be able to find out who is behind it.

This is absolutely not allowed! We will never let this happen, so we must guide everyone in the right direction.

Miu: "The murderer is Quantai and there is no mistake!"

"I told you it's really not true!"

"It's ugly when a man makes excuses." Rotor said.

"It's obviously in a straight line, and there are no obstacles in the middle." The maid said, "The only possibility is that it's you."

"Wait, this is wrong."

Xiao Feng said: "It is still impossible to throw a shot put from the audio-visual room and hit classmate Tianhai."

"Because there is an obstacle between Tianhai and Quantai."

"obstacle?"

Lin Xiao said: "It's a movable bookcase. When Tianhai was killed, the movable bookcase should have been open."

"There is also evidence that the bookcase was indeed open when he was killed." Xiao Feng said.

"Look at this photo."

"This is the second photo taken by the camera that captured the secret door."

"It's a photo of Tianhai being killed." Ji Wang said.

"In the photo, the bookcase with the secret door is fully open, right, and then the bookcase automatically closes." Xiaofeng said.

"It was completely closed the moment we stepped into the library."

"Before that, this bookcase was always open. Even if a shot put was thrown towards Tianhai from the audio-visual room, it would probably hit the bookcase, right?" Xiao Feng said.

Ryoma: "I see, then the possibility of throwing a shot put disappears."
