"Siyan, can you determine the cause of Jiaojiao's death?" Xu Tian asked.

"I'll see."

Siyan inspected Jiaojiao's body in public, Jiaojiao had no external injuries, but Jiaojiao's complexion did not look like she had been poisoned, so it was difficult for Siyan to make a conclusion.

"We need a doctor, we don't know the specific cause of Jiaojiao's death, and it will take a big detour to find out the truth." Xu Tian said.

"Doctor, don't think about it, now that there are three dead people here, I suggest you also examine Mr. Fang's body." Xiao Ai said.

"I understand what Xiao Ai means, Mr. Fang may indeed not commit suicide, but Mr. Fang's skin color has not changed much, but the cause of Mr. Fang's death is very much like swallowing poison, it is possible that Jiaojiao is also the kind of poison that he swallowed, and not all poisons will change people's skin color." Xu Tian said.

"It's really the truth, but the category of poisons, and whether Mr. Fang and Jiaojiao died of poisoning, these can't be concluded, and the problem we are facing now is that there is no way to determine these things, no one here understands medical skills, and this kind of case handling is like a blind cat catching a mouse." Xiao Ai said.

"Then let's start digging out the clues! First of all, why did Xiao Ai pretend to be Jiaojiao, although Xiao Ai has already said the reason just now, but I don't think it's specific enough, although Xiao Ai claims to be born in this village, but Xiao Ai hasn't been back to the village for a long time, right? And Xiao Ai just met Jiaojiao last night, why did Jiaojiao entrust Xiao Ai to help observe the family? Xu Tian asked.

"Do you think I'm going to be like you and go to the island without doing any preparations? Since you've asked this question, it doesn't hurt to tell you. Originally, the main purpose of my trip south this time was to land on the island to find relatives, and I just followed the old village chief here to help Aunt Xu. I had already made contact with Jiaojiao before I went south, and I met Jiaojiao on the Internet, which was four years ago, and Jiaojiao and I were netizens. Ever since I knew that Jiaojiao's hometown was on this island, I asked Jiaojiao a lot about this island, although Jiaojiao and I are not the kind of netizens who talk about everything, but at least I didn't lie to Jiaojiao, Jiaojiao had already entrusted me to observe her family before I came here. Xiao Ai said.

"Xiao Ai also told Jiaojiao about your disguise and makeup?" Xu Tian asked.

"I've already said that I didn't lie to Jiaojiao, which means that Jiaojiao knows everything about me." Xiao Ai said.

"Then why didn't Jiaojiao and Xiao Ai recognize each other when they met last night?" Xu Tian asked.

"Because Jiaojiao doesn't want other people to know about this, and cautious people like us always need to hide it from our own people, even if we are most familiar with them, this is also the basic quality of a detective, those big-mouthed detectives told their families about the procedures for solving the case, and then the news spread, such things are not uncommon." Xiao Ai said.

"How do I feel that Xiao Ai has a deep discrimination against me!" Xu Tian smiled bitterly.

"You just don't continue to say these useless words, in short, Jiaojiao's cause of death is the most important thing now, and what happened after Jiaojiao left in the morning, now Yang Qi is nowhere to be found, we should find Yang Qi as soon as possible." Xiao Ai said.

"Where did you originally let Yang Qi take Jiaojiao?" Xu Tian asked.

"I asked Yang Qi to send a message to Dongzi, saying that they would go to the town with Jiaojiao pretending to be me, but in fact, they just went out of the village to hide for a while, and the scheduled time was to come back in the afternoon, but now it is almost three o'clock in the afternoon, and the snowstorm is so heavy, Yang Qi has not come back yet." Xiao Ai said.

"Xiao Ai! You should have told me about this earlier, even if we searched for Yangqi now, it is unlikely that even we will be killed if we go to search for people on mountain roads in such weather. Xu Tian said.

"I know that Yang Qi will not be the murderer, and I also believe that Yang Qi is not so squeamish, now Yang Qi must be somewhere and can't get out, and he will naturally come back when he can come back." Xiao Ai said.

"Then aren't you afraid that Yang Qi will be trapped somewhere? If Yang Qi was caught in a snow disaster and couldn't get out, then Yang Qi would be dead today. Xu Tian said.

"Yang Qi is not a fool, and the blizzard does not fall just as it is said, when snowflakes with goose feathers fall in the sky, Yang Qi should return. So since Yang Qi didn't come back, it means that he may have something to do. Xiao Ai said.

"Maybe the murderer knocked Yang Qi unconscious? If the murderer trapped Yang Qi somewhere, or left Yang Qi in the wilderness......" Speaking of this, Xu Tian suddenly figured it out, and hurriedly grabbed the door.

Teacher Jin also understood what Xu Tian was thinking, since Jiaojiao would have been killed in the morning, then it is possible that Yang Qi and Jiaojiao were attacked by the murderer without leaving the courtyard of the Chen family, in this case, everyone in the Chen family may be the murderer, and it is a waste of time to ask the people here at this time, so they can only start searching for Yang Qi's whereabouts in the Chen family as soon as possible.

When Teacher Jin chased him out, Xu Tian was gone, and Teacher Jin leaned down to follow Xu Tian's footprints on the snow, all the way to Danxin's residence.

It is true that this is the most likely Tibetan here, and when Teacher Jin arrived, the door of Jiaojiao's room had been kicked open by Xu Tian, and as expected, Yang Qi was tied up in Jiaojiao's room.

"It's late." Xu Tian said.

"You don't need Danxin, you still have breath." Teacher Jin tried Yang Qi's snort and said.

"It's not like he suffered a heavy blow, it should be something like a drug or sleeping pill that knocked Yang Qi down." Xu Tian said.

"Hurry up and search this room, I'll carry Yang Qi back first, the danger shouldn't happen, and there should be a murderer among the remaining four people." Teacher Jin said.

"Dongzi, Chen Po, Li Nana, and Chen Fan." Xu Tian said.

"That's right, the rest of Siyan and Xiao Ai are their own people, and now there are a total of nine people in this Chen family's ancient mansion with Yang Qi, maybe the murderer still has a move, I will take Yang Qi and leave first." Teacher Jin said.

Xu Tian, who stayed, immediately began to search Jiaojiao's room, the first thing to search was Jiaojiao's wardrobe, and sure enough, there was a major discovery, Jiaojiao's wardrobe had a laptop, and there was also a wireless network card, it seems that Jiaojiao often surfed the Internet in the room, and the mobile phone signal was only cut off yesterday, that is to say, Jiaojiao had been able to contact the outside world before yesterday.
