Up to now, among the five people who conspired on the cliff at the beginning, Chu Fu, nicknamed Viperhorn, has died, and the cause of his death is actually not very complicated.

When Chu Fu got up that morning, there was no second person in the room at all, because everyone else was in his room at that time, two maids, one was cleaning downstairs, and the other was cooking breakfast in the kitchen, Mo Xiangxi fell asleep in the room on the first floor the night before, and was woken up by Dai Lu, so it was impossible to enter Chu Fu's guest room.

When Chu Fu got up, everything was safe, until he walked into the bathroom, and the whole person's condition was still very stable. It shows that the killer did not apply the poison somewhere in the room or bedside. Chu Fu didn't eat anything in the morning, so there was no possibility of food poisoning.

After entering the bathroom, Chu Fu complained that the maid did not help the guests clean up while going to boil water. There were only two things he came into contact with, an electric kettle and a faucet for water.

According to what Mo Xiangxi observed in the room, the electric kettle was open, indicating that Chu Fu had filled the kettle with water before he died, and plugged it in. That is to say, at least there is no problem with the surface of the kettle and the place where the human hand can reach.

And what about faucets? Of course, there can't be a problem, after Chu Fu turns it off, he can still have time to plug it in, which means that the faucet has not been smeared with poison.

There is another problem here, that is, the time when the poison enters the body, if there is no wound on the surface of Chu Fu's skin, the poison must penetrate into the internal organs for a long time, and it is easy to be discovered by the parties. This is because the skin will appear abnormally before the internal organs.

If you want the toxicity to hit in time, you have to let it penetrate directly into the bloodstream. Then there are only two possibilities: first, oral; Second, there were wounds on the surface of the victim's skin.

But what is puzzling is that both of these possibilities are also difficult to establish, we have said before that Chu Fu did not eat anything in the morning, so there is no possibility of poison entering through the mouth.

As for whether there are wounds on the surface of the victim's skin? Whether this wound was deliberately done by the murderer, we have to look at Mo Xiangxi's behavior. After Mo Xiangxi saw Chu Fu's corpse, he must have been frightened for a moment.

When he reacts, he will definitely rush into the kitchen first, wipe out the traces left by Chu Fu, and then throw the body out of the window, then, Mo Xiangxi will definitely touch the surface of the electric kettle and the power plug like Chu Fu.

Therefore, if the murderer planted something poisonous and sharp in these two places, Mo Xiangxi would definitely be injured. There was no reason for his injuries, so it can be said that the murderer did not do anything in these two places.

Or it can also be said that the murderer has cleaned up the hands and feet of these two places, which involves the problem of the door, why is the door locked? Who is the anti-lock?

Is it Chu Fu? How can it be! Chu Fu died directly in the bathroom, so is it Mo Xiangxi? Maybe, but don't forget, before Mo Xiangxi came back from the mysterious valley, Xiao Mo and Yun Yadui had already confirmed that the door of Chu Fu's room was locked.

So our question should be asked: Who locked the door of Chu Fu's room before Mo Xiangxi returned? This person could only be someone who spent the afternoon at Kashinv's dacha.

We can use the elimination method, first of all, Xiao Mo, is it possible? Yes, Xiao Mo didn't walk out of the room until noon, and when he came out, his face was extremely bad, and he kept saying that he had an upset stomach and didn't even eat much?

Isn't this reaction very similar to Mo Xiangxi, who is currently finding a corpse in Chu Fu's room? It is possible that the bad stomach is really sick, or it may be caused by seeing something disgusting.

Xiao Mo is in the room in the morning, he has a lot of time to act, even if two people have gone to look for him, but it won't take much time, why didn't he come out for breakfast and lunch? To sum up, we can see Xiao Mo as the first suspect in this homicide.

The second let's look at Xiao Su, Xiao Su came downstairs after breakfast started at 8:30, he didn't delay for long, and after arriving downstairs, he kept sitting in the sight of others, until he greeted Mo Xiangxi and entered the room on the first floor.

Xiao Su entered the room on the first floor to find a map to the mysterious location, and after finding the map, he immediately left the Kashenv villa with another companion, and did not return until about 12 noon, so it can be determined that before noon, Xiao Su definitely did not enter Chu Fu's room to clean up the evidence.

So after noon, according to Xiao Su's own words, he has been painting on the first floor. And it is true that there are unfinished paintings on the drawing board. Yun Yadui saw in the afternoon that the outline of the morning glory on Xiao Su's painting had been completely depicted, and only the work of coloring was needed.

To do this, it is impossible without two or three hours, so this proves in disguise that Xiao Su did not have time to clean up the evidence in the afternoon. To add that these suspects do not need to go directly to the door to enter Chu Fu's room.

Although the Kashinv villa has three floors, it is actually not very high, and as I have clearly mentioned when describing the structure of the house, the rear of the Kashinv villa is completely different from the front, and the front may look similar to an ordinary building, but there is only an upward staircase at the back.

It leads to a pavilion-like space, and then you can see three rooms side by side, one of which, apart from the two warehouses, allows access to the place where the guests live, so that the second and third floors are in a similar position.

With the staircase landing on the second floor as the central point, extending to both sides, it is possible to enter the rooms where the owners of this kind of house - Mo Xiangxi and Xiao Mo live. However, the landing on the second floor did not extend upwards to the staircase on the third floor.

The passage to the third floor is in a small elevator on the side of the first floor, which in itself distinguishes the third floor from the second floor. In other words, although nominally it is the third floor, it is actually at the rear of the second floor. The first half of the house is the first and second floors, and the owner's room is on the top of the hall on the first floor.

The second half of the house, which connects the fence to the small 'garden', is on the roof of the rear warehouse, and may even be even lower than the front.

This is why Mo Xiangxi threw the body out of the window directly, and he could turn it directly from the window of Chu Fu's room to the back of Kashenv's villa. If it was a normal third floor, he would probably have to be a little injured if he went out like this. It was impossible to bring the body into Song Yuehua's room.

Leaving aside the matter of the house, let's pick up the previous topic, Xiao Su was temporarily ruled out of murder suspicion, and the next person was Yun Yadu, who was in the Kashenv villa all day on May 21, and was also the most restless person in the villa.
