"Xiao Ai is becoming more and more like a detective, could it be that Xiao Ai is here to investigate me?" Xu Tian teased.

"Don't you really see that some of the villagers have fear written on their faces? If you don't see it, then you're not qualified. Xiao Ai said.

"Of course he can see it." Teacher Jin said. "But it doesn't help to see or not to see, the point is that there is no local person to help us, no matter what, we can't ask the villagers, like this, we have to have someone who can convince the villagers to cooperate with us."

"Oh well! Let's see! Xiao Ai walked outside the courtyard gate with an unhappy face.

"Xiao Ai!" Xu Tian chased after him and said. "There is an important thing I want to ask you, we actually have another purpose for coming to this island this time, that is, this was once Commander Fang's foothold, do you know which of these five villages is where Commander Fang once stayed?"

"The entire island has been conquered by Commander Fang, but the time is very short, Commander Fang has patrolled the island, and finally chose to settle in the northernmost place, but Commander Fang may also have lived in this village." Xiao Ai said.

"I didn't think about it so much last time when the old village chief explained, I only thought of these questions when I came here, about Commander Fang, the old village chief must have told you a lot, right?" Xu Tian asked.

"Everything I know will tell you, when Commander Fang landed on the island with his men with arms, here are ordinary fishermen and farmers, and you should know the result without me saying it. But then Commander Fang gradually grew old and changed, after more than ten or even twenty years of consumption, Commander Fang's arms were almost consumed, at that time it was the era of war, it was difficult for Commander Fang to buy weapons again, and finally the islanders here gradually took Commander Fang's chassis back, and after Commander Fang died, the rule of the aborigines was basically completely restored here. Xiao Ai said.

"This island was so close to Shanghai Beach, I don't think it would be possible for this place to stop, isn't there a war on this island?" Xu Tian asked.

"I don't know about these things, and I left my hometown since I was a child, so I don't know the rest of the problems." Xiao Ai said.

"This matter is also something we must investigate clearly, I feel that the information provided by the old village chief is still not enough, if you want to uncover the identity of the ruling Tai Sui, Commander Fang's deeds should be very important." Xu Tian said.

"That's why you're looking into these things, not us." Xiao Ai said.

"Alright! Does Xiao Ai mean not to help us investigate Commander Fang's deeds? Xu Tian said.

"I have other things to do, I can only say sorry to you, and I'm not a detective, so I can't help you much." Xiao Ai turned his back and said.

"Is it about Xiao Ai's hometown? Speak up if you need help. Xu Tian said.

"Hey!" Teacher Jin shouted in the courtyard. "Come over and record, I'm going to perform an autopsy."

Xu Tian hurriedly walked into the courtyard, and Teacher Jin had already put Lao Li Ping on the ground.

"Where's the fatal wound?" Xu Tian asked.

"No fatal injuries were detected, Lao Li's whole body was only wounded at two wrists, Lao Li's two hands were cut off, and they were taken away by the murderer." Teacher Jin said.

"There are no other wounds, so that means it could be poisoning?" Xu Tian asked.

"I'm not sure if there was a doctor." Teacher Jin sighed.

"Lao Li should have been killed by the murderer first, and then his hands were cut off, otherwise this kind of pain Lao Li would not have been silent, but it is also possible that Lao Li voluntarily did not speak out, and this situation has not been absent in previous murder cases." Xu Tian said.

"If Lao Li voluntarily didn't speak out, it probably means that he wants to shield the murderer, or he has been scared, I still think the former is more reliable." Teacher Jin analyzed.

"But I still think that Lao Li should have been put down by the murderer first, at least he should have been unconscious first, the pain of his hands being cut off is unbearable for ordinary people, even a well-trained person should be doubly painful to scream, an honest villager like Lao Li, he can't bear this pain." Xu Tian said.

"Now we need to know the cause of Lao Li's death, as well as the route of the murderer's escape, the backyard has basically been denied, and we are watching at the front door, so now there are only the courtyard walls on both sides." Teacher Jin said.

"It's impossible to get close to the courtyard wall of Gaopo, which is also within our line of sight, and the roof is also unlikely, I remember standing on Gaopo where you can see the roof of Lao Li's house." Xu Tian said.

"Then the last thing left is the other side of the courtyard wall, and there should be people on that side of the courtyard wall." Teacher Jin said.

"Are you going to visit?" Xu Tian said.

"Don't use it for the time being, if you go, you will definitely eat a closed door, let's study the cause of Lao Li's death first!" Teacher Jin looked at the watch on his left wrist and said. "More than half an hour has passed since the incident, and the corpse has not changed color, so it should not be the poison we are common in handling cases."

"Could it be organ failure? For example, myocardial infarction, sudden heart attack or brain death are difficult to see on the surface. Xu Tian said.

"I think brain death is more reliable, and there are signs of heart attack." Teacher Jin said.

While speaking, Teacher Jin raised Lao Li's head, and on the surface, he couldn't see anything at all, Lao Li's hair was very thick.

"I can only shave Lao Li's head." Teacher Jin said.

Xu Tian found a pair of scissors and an old-fashioned razor at Lao Li's house, and immediately after Mr. Jin shaved Lao Li's hair, he saw a small red dot on Lao Li's head.

"Yes, sure enough, the cause of Lao Li's death is in the head." Teacher Jin said.

"It's like a very small pinhole, and a needle like this shouldn't be able to pierce the skull, right?" Xu Tian said.

"The pinhole is in the blood vessel, which should be a drug that can kill the human brain." Teacher Jin said.

"If you can accurately find blood vessels on the head with thick hair, either Lao Li is defenseless against the murderer, or the murderer is a very powerful doctor, and the murderer may know Lao Li's physical condition very well." Xu Tian said.

"All three of these things you said can happen, do you remember when Lao Li suddenly called the two of us to his house? At that time, Lao Li should have wanted to say something to us, or maybe he wanted us to meet someone. Teacher Jin said.

"The murderer is very likely to be the person Lao Li wants us to see, or it may be that the murderer sneaked into Lao Li's house and hid when Lao Li was not at home." Xu Tian said.
