Who is the murderer?

17:00- The soup cooked in summer is delicious, but the bowl is big and there is no spoon. Everyone must drink soup with a bowl. Everyone drank the soup, including Zhou. It is clear here that Zhou Luo Elm can hold the bowl with both hands at this time.

20:50—— Summer timeline, when Zhou was given a bag, Monday held a bag in one hand, and then waved his hand to indicate that Zhou's injured hand could not hold a paragraph, indicating that Zhou's injured hand could not hold the bag. Holding a bowl and carrying a bag are all reactions after class this week, indicating that his hands are normal at 17:00 and abnormal at 20:50.

We all know that Zhou's hand was injured three days ago. He can ski today. How can he not take a bag of books? Most importantly, his hands are always normal, and he can't lift them until the last moment. In other words, Zhou's hand was injured twice today, and the injury time was between 17:00- 20:50.

The main timeline of Coward

From 10:00 to 10: 10, everyone came to B&B and packed their things in their rooms. Yin Su found that the window of his room couldn't be closed, so he borrowed a rope from the horse, but the horse didn't agree. Seeing this, Peng Cuo punched the horse, and then helped to hold the rope to fix the window (Peng Cuo hated horses, so he put high-strength nanowires in the horse's room).

10:50, Yin Su went back to his room to sleep and closed the curtain. The curtain is very opaque (Yin Su's room is just below Yao Zhang, Yin Su drew the curtain, and someone came down from the window of Yao Zhang's room without being found by Yin Su). At the same time, Zhou Shang stole two climbing ropes from Ma's room under the pretext of going to the toilet.

10:59, said he was going to Zhao's toilet, left KTV, and met Zhou after going out. At this time, Zhou recorded a conversation (the voice was normal at this time).

1 1:40, Yao Zhang came back from the toilet and asked Yao Zhang why it takes so long in summer. Yao Zhang said that he likes to play with his mobile phone when he goes to the toilet.

It usually takes 40 minutes. Then I exchanged high notes with Zhou. In summer, I went to Mayanyang to put out cigarettes.

13:30, Zhou He's singing contest is over. Yao Zhang is no match for Zhou Luo, so he sang himself hoarse.

14:00- 16:30, ski theater.

17:00 Let's have dinner together (everyone's story is that Zhou's hands are almost ready at this time, at least he can hold the bowl with both hands).

18:30, after dinner, the horse will go out for a walk, go to the room to chat in summer, and the others will go back to the room.

18:40, Zhou enters Ma's room and puts sleeping pills in the water cup in the room. Yao Zhang is the only one on the second floor now. Zhou took two climbing ropes and went up to the second floor. Zhou pretended to chat with Zhang in his room and turned on the radio in the room at the same time. The music is loud, which Yin Su and Pengcuo heard in the soft summer at the beginning of the season.

19:05, Zhou strangled with a rope to cover up the struggling voice. Then Zhou went to Xia's room and took the summer mop, opened the window of the room, put the corpse and mop down from the window with a rope, went downstairs along the rope, and took a water cup from his room.

Then Zhou took another rope, a corpse and a mop to the summer house by the lake.

19: 15, leaving the hotel in summer, I found the surrounding scenery beautiful and the ground around the hotel very flat (because a dagger was buried behind Zhou, a small mound appeared in the corner outside the hotel).

19:20, Zhou came to the lake near the hill (it was ten minutes' walk from the hotel to the lake, but it took five minutes), tied the body and mop to one end of the rope, and tied the stone to the other end, and then sank the body and mop to the bottom of the lake.

19:25, Zhou threw the stone used to pile the statue into the lake, and smashed many pits on the frozen lake to cover up the pits smashed by the body. Then Zhou dug some stones and built a new statue. Finally, Zhou brought some black mud from the river with a water cup and returned to the workplace (ready to frame and confuse the horse).

19:35, Zhou went back to the second floor by rope. Every time he puts away the rope, he tidies up his clothes.

19:45, Zhou closed the music school and people never heard loud music again.

19:48, Zhou recorded the sound at KTV and turned it to the maximum (Zhou did this on the one hand to create the time of death, and on the other hand to let Peng Cuo and Ji Churou know that the deceased had left the room and could start work. There is a dialogue in the audio.

Zhou: "Hey, what are you doing?" Yao Zhang "three tubas. After the program was broadcast, Zhou deleted the recording, and Ji Churou, Peng Cuo, Xia, and Xia heard the recording. There is music in the background of this conversation. Those who heard it can be sure that this conversation appeared after the music was turned off. There is one thing to doubt here. )

19:50, Zhou went back to his room, put the rope under the bed (Zhou did this to make others think that the horse was setting himself up), then went to the toilet on the second floor and began to pay attention to the situation of the dead room (Zhou should master the action of softening Peng Cuo at the beginning of the season to make sure his plan was foolproof).

19:52, Ma went back to his room and drank the water containing sleeping pills.

19:55, the horse fell asleep. At the beginning of the season, Rou entered the dead man's room, and on the dead man's desk, he made an ejection device with his head tilted above the seat. If Yao Zhang sits here, the dagger can pierce Yao Zhang's throat. At the same time, Ji Churou left a note on the desk of the deceased.

Induce the victim to open the drawer. Once the victim opens the drawer, the dagger will pop up automatically.

The note that Ji Churou put in the dead man's room was not his own handwriting, but a copy. Yin Su's family is poor and can't afford books. Usually, she has developed the habit of copying dictionaries.

Ji Churou bought a thin piece of paper, and Mulin Dictionary wrote this note (Ji Churou framed Yin Suo). After that, I took out a cigarette with a horse's spleen, which was prepared at the beginning of the season. This cigarette is treated with potassium cyanide. Once I smoke this cigarette, I will die in less than a minute.

At the beginning of the season, Rou lit the cigarette and put it in an open ashtray (the clue shows that there is still more than half of the cigarette, which means that no one smoked it after lighting it, so the cigarette fell off), and then Rou put the lighter on the table.

When Zhou saw Ji Chu Rou enter the room, he quickly entered Ji Chu Rou's room and hid the bottle that he had given sleeping pills to the horse before in Ji Chu Rou's room. It is well known that the contradiction between Rou and Ma at the beginning of Daoji made Ma think that Rou had framed him.
