"First of all, the time of the crime is early this morning, so none of us have an alibi, but everyone should also pay attention to the fact that the murderer first entered the victim's room and then used some method to create a secret room. Think about it, if someone knocks on the door in the middle of the night, especially in this case, will you open the door, unless it's someone you know, right? So the three of them are the most suspicious. As he spoke, Tang Yuzhe pointed to the three monks. "When we talk about the murder weapon, there are only two fingerprints on the monk and the victim, and judging from the clean key, the murderer must have worn gloves and erased his traces when he committed the murder. So, anyone can strangle the victim with a piano string, and then use the rope to disguise suicide, because there are no fingerprints on the piano string, and I know that the monk will send something, so as far as the murder weapon is concerned, all of us are suspected of the same. "As for the technique, it should be that the victim was strangled from the rear with a piano string first, and then disguised as a suicide with a rope, as for the formation of the secret room, because the position of the key is too special, there are many ways to do it, such as using a rubber band to bounce it into the ....... Speaking of this, Tang Yuzhe paused, and then said: "Because the time is too short, I can only give the most likely explanation, that is, an acquaintance committed the crime, but there are not many doubts I haven't figured out, such as the flawed piano line, the monk's motives, etc., but from the feedback just now, it seems that the monk and the victim are not too familiar, so in terms of motivation, it can be reluctantly explained with 'convenient start'." As soon as Tang Yuzhe said no, Lu Renjia immediately asked: "This is the most likely, isn't it right, shouldn't the biggest possibility be that he committed suicide." "No way. Tang Yuzhe and the monk spoke at the same time, and then the monk smiled at Tang Yuzhe and motioned for her to speak. "Although I have only been in contact with him for a short hour or two, I can clearly see that he is an arrogant person, and the crux of the matter is here, the benefit! The benefit is too small, I believe the monk thinks so too. If he really committed suicide, although he also reached the victory conditions, but at most it is a guaranteed evaluation, no misleading, reasoning points, no more rounds of analysis, his score will not be too high, and as far as I know, he will not be willing to be second. Therefore, if you want to start with his suicide, you must first solve the problem of income. After listening to what Tang Yuzhe said, even Gu Yi and Xu Zekai nodded again and again.

When the bell rang at nine o'clock, the housekeeper standing aside said: "When the time comes, please identify who the murderer is, when the housekeeper finished speaking, everyone pointed to the monk, including Xu Zekai and Gu Yi who had gone through a long psychological struggle, and the monk himself." Five seconds later, the butler spoke slowly: "Now announce the answer, you have identified the mistake, and the murderer has made a choice and asked me to bring you a message, his/her original words are: 'I expected you to fail to identify, so I will not leave, because it is too boring, and I would like to give you a reminder here, your main concern is not the surface of the problem, but to take a long-term view and pay attention to what is behind it!'"

Soon after the monk returned to the bedroom, Xu Zekai and Gu Yi came together to apologize to the monk, and the monk waved his hand and told them not to care too much, it was only the first day. Then, Xu Zekai took out a note and handed it to the monk, saying that this was the first bag that Chen Long left them, and asked them to open it the day after he had an accident, but they couldn't help but open it after the vote, only to see the note written: "When you see this note, it means that I have an accident and go first, if the monk is still there, no matter what happens, please believe him, at least I believe that he will not harm us, and then rely on him to act." If the monk is no longer there when this note comes into play, I can only hope that you can help Xu Zekai overcome his laziness. If you can do it, there is still salvation, of course, I don't think it's very likely, it's better to wash and sleep, if there is only one left to care about you, then congratulations, it's better to wash and sleep. I just hope you won't need it, otherwise the enemy's strength will still have something. "So Master, what should we do?" "Wait!" the monk said, "I believe that tomorrow is the time for Lu Renjia's side to act, first find out what the enemy is good at, and then make plans." You'd better not be left alone tomorrow, be careful. The monk leaned back on the chaise longue with his eyes closed, as if thinking about something.

It was nine o'clock in the morning, and the monk was the last to enter, but this morning everyone gathered in the restaurant to eat, but the monk had just eaten and the others had already finished eating. "I heard that the indoor pool next door is open, so let's go together. A girl in Lu Renjia's team said, and then Lu Renjia and his party of four turned around and went to the next door, then Tang Yuzhe, then Xu Zekai and Gu Yi, and finally even the monk put down the lotus seed cake in his hand and went to the next door, but as a master, he used to meditate by the pool and spoil the scenery.

"In fact, if you exclude this so-called killing game, this castle is really a good place to spend a vacation, elegant, gorgeous, and have everything, even swimsuits and swimming rings. Tang Yuzhe swam to the monk's side and said to the monk. "Yes, yes. The monk also opened his eyes at this time, looked at the men and women playing in the middle of the pool, and said: "But they are the only ones who can enjoy it, and the only ones who can really participate in this game and play with each other are you, me, Lu Renjia, and Chen Long, who has died." Tang Yuzhe leaned against the edge of the pool and said. "Yes, yes. "When I say Master, do you just say 'Ranye'?" Tang Yuzhe listened, and before he could make a grimace at the monk, a change suddenly happened.

Water and fire are two things that cannot coexist, but at this time, a fireball ignited in the pool, and the fire seemed to be using water as a carrier, scattering with the water. The people in the pool were scrambling to swim to the shore, but they were more or less affected. Soon, the butler appeared, and as he waved a handful of white powder into the sky, the injuries on everyone's bodies and the fire in the mud pool dissipated at a speed visible to the naked eye, and the only proof of this disaster was a corpse in the middle of the pool.

It's time for Tang Yuzhe to show his real skills again, but this time the requirements for technology are a bit high, not to mention that the corpse was burned beyond recognition, it was almost ripe, and besides, the water was on fire, and the unsolved mystery of this century was, so Tang Yuzhe had been inspecting the scene with a gloomy face.

"Hey, what are you doing?" Tang Yuzhe looked at Lu Renjia writing and painting by the wall, and asked. Lu Renjia didn't raise his head, continued to write, and replied: "My sheriff, of course I'm planning for the crime, otherwise what else can I do, appreciating the 'art in front of me'?" Suddenly, Tang Yuzhe seemed to have found a breakthrough and rushed out of the pool.

Tang Yuzhe rushed to Chen Long's room, only to find that the original list was placed next to the bedside table, and anyone could be flipped. Tang Yuzhe flipped through the list, and the first page was a simple map, and some places with many tools, such as the chemical storage room and the sports storage room, were circled with a red pen. Tang Yuzhe carefully recalled the scene this morning, and felt that she should start from the chemical storage room, and when she walked towards the chemical room, she also flipped through the list, I have to say that Chen Long wrote in detail, and even the items that were most likely to become tools for crime were emphatically marked. When Tang Yuzhe finished counting, he found that the sodium and a large amount of Na2co3 that had been marked were missing. At this point, the mystery of the pool fire case was solved.
