First, the prisoner set up a mechanism to jam the door in Room 312 before the access control time came at ten o'clock, in order to complete the technique of disappearing into thin air.

That is, tie the rope to the object that is stuck on the door, and then throw the other end of the rope out the window.

After that, after the night time period started at ten o'clock, the prisoner deliberately let the three of them witness his presence, making them mistakenly think that he had escaped into an empty room, when in fact he had entered another room.

"The room the prisoner escaped into was not an empty room, nor was it the victim's room, right?"

"That's right."

"Which room is that?"

"Of course it's the prisoner's own room, Sister Yui."

May Yujie recalled the room allocation situation on the first night.

"What did the prisoner do after that?"

"Go out of your room and climb to the rooftop. Almost all ten rooms were in secret room condition that night, but only the prisoner's own room was not a secret room. Presumably the iron bars in the prisoner's room can be removed easily."

"The prisoner climbed out of the window and went to the rooftop?"

"That's probably it. Maybe he set up ropes or something in advance to make it easier for him to go up."

Once on the rooftop, you don't have to worry about being seen by others, and you won't be blocked by the walls between rooms. You can go straight to the room where the target is.

"After boarding the rooftop, the prisoner immediately pulled the rope hanging outside the window of the empty room, right?"

The rope was obviously used to remove the thing blocking the door.

"Yes. It's possible that the rope was pulled into the window of the prisoner's room in advance and passed through the hook on the rooftop."

"That's it... considering the timing when we passed the corner of the corridor, the prisoner didn't have time to walk to the empty room. After he entered his room, he immediately pulled the rope..."

As soon as the prisoner pulled the rope, they successfully witnessed the disappearance phenomenon.

However, this approach is a trap.

In the end, he did successfully trap the girl and Nanucun with an empty room.

And at this time, the prisoner——

"We led Mr. Ochata to the window on the rooftop, right?"

May Yuyue finally understood the whole story of the incident, but will the cautious Chaxia really be deceived by the prisoner's sweet words?

Everyone knew that this man was a conspiracy theorist, and it was not easy to deceive him.

But according to the bespectacled girl’s previous impressions, Chaxia seems to be quite afraid of the night. If someone tells him that ‘there is a way to go out’, he might be fooled.

However...even if the prisoner uses this method to get Cha Xi to come near the window, his arms still can't reach the other party's neck.

It's hard to tell whether he can touch his head or not.

After all, the hand reaching out from the window wants to touch the victim's neck...

This height is really difficult to reach unless you extend your arms.

But maybe only yoga masters can do this kind of thing. No, this is probably also difficult for yoga masters.

Since the arm can no longer be extended, the victim can only be approached actively.

As long as the victim is placed a little higher than the surrounding area...

"It's a little higher... Huh? Can't you just find something to put your feet on?!"

In order to see the scene outside the window, the victim found something to put his feet on.

But what to find to put your feet on?
