"You go down with me." Teacher Jin said.

"I'm going to survey the scene, and that person must have been at dinner when he was poisoned." Li Zhitong said.

"So, do you believe I didn't poison that man?" Teacher Jin asked.

"You wouldn't do such a thing, and I don't think Kang Yuliang would be so stupid, he wouldn't kill people in front of you." Li Zhitong said.

"But it's possible that he poisoned him during the dinner, which can be traced." Teacher Jin said.

"Of course, everyone is suspected of poisoning him, and the murderer is still here to cause trouble." Li Zhitong said.

"Apart from Dr. Lin, if there are other people who come to make trouble, it will be enough for the two of us to toss." Teacher Jin said.

"What? Are you scared? Li Zhitong asked.

"Don't mess with me, tell me about the situation at the time, and I'll help you analyze it." Teacher Jin said.

"Everyone was about to disperse, and an hour before the man died, everyone should have been lying on the table and pretending to be asleep! At that time, everyone was observing other people, and it can be said that it was impossible for everyone to act without permission at that time, because there were too many people at the table at that time, and they were all staring at other people, and if the murderer acted without authorization, it was likely to be discovered by others. Li Zhitong said.

"It's possible that the bottle was poisoned." Teacher Jin said.

"I don't think it's very likely, I noticed the deceased, he didn't specify which bottle to take, and I remember that the deceased took someone else's bottle and took a big sip of it while pretending to be drunk, and then the owner of the bottle took a few sips of it himself. The poisoning reaction is a chemical poison, and if the deceased had already drunk the poison into his mouth at that time, it is very likely that the poison would be passed on to someone else while drinking into someone else's bottle. Li Zhitong said.

"At that time, maybe the deceased had not been poisoned, but this is a bit unreasonable, after all, the murderer seems to be a very cautious person, and the murderer should not do such a thing that would kill someone by mistake." Teacher Jin said.

"That's right, the murderer's mind is very meticulous, and the murderer will not kill anyone else by mistake, but when did the murderer poison him?" Li Zhitong said.

"Whose bottle did the deceased come into contact with?" Teacher Jin asked.

"It was the bottle of Huang Quan, and the deceased took a big sip of the bottle, and then I saw that Huang Quan took the bottle, and Huang Quan himself took a few sips of the bottle." Li Zhitong said.

"Then it's not poison in a bottle." Teacher Jin said.

"Although a needle hole was found in the neck of the deceased, it is not certain that the deceased must have been injected with venom." Li Zhitong said.

"That's up for debate, but it's better to find a syringe, which is closed and shouldn't be difficult to find." Teacher Jin said.

"It's useless, we don't have the tools and instruments to identify fingerprints now, so what can we do if we find the needle? If you wait until tomorrow to take the needle to the police station for fingerprint comparison, the daylily will be cold by then. Li Zhitong said.

"But there is one thing I need to tell you, when I fought with the deceased, there should have been no needle in his neck." Teacher Jin said.

"Are you so sure?" Li Zhitong said suspiciously.

"Almost 80 percent sure! And when I fought with the deceased, his physical strength was very good, it didn't look like there was a toxin lurking in his body at all, if the deceased had been injected with venom dozens of minutes ago, then although he would not have died immediately, his physical fitness would definitely have decreased a lot. Teacher Jin said.

"Then let's assume that the deceased was injected with venom after fighting you, so who can do it?" Li Zhitong said.

"I was in the attic and clearly heard that the deceased and Kang Yuliang had a quarrel with two men when they went downstairs, it should be the two strange bail prisoners, the deceased had contact with Kang Yuliang at the time, and the rest was only with the two bail prisoners." Teacher Jin said.

"It is impossible for these three people to have the opportunity to stab the deceased with a needle, according to the relationship between them, the deceased should be above the three of them, if those three subordinates dare to stab the deceased with a needle, then the deceased should not sit still." Li Zhitong said.

"It also makes sense, because the situation here is very bad for everyone, and whoever himself with a needle should think that the needle is not good for them." Teacher Jin said.

"That means the deceased didn't find out that he was being stabbed." Li Zhitong said.

"This is impossible, the eye of the needle that Xu Tian found at a glance must be very conspicuous, someone stabbed the deceased with a needle, and the deceased could not find it." Teacher Jin said.

"So...... There's only one possibility left! Li Zhitong said.

"You can't be suspicious of me, are you?" Teacher Jin said in surprise.

"Now only the deceased has the chance to be stabbed by a needle when fighting with others, and only during the fight may not know that something has stabbed him." Li Zhitong said.

"This can be omitted, I didn't kill anyone." Teacher Jin said.

"I'm just making an assumption, I'm not identifying you as a murderer." Li Zhitong said.

"But there is another hypothesis, have you ever thought that the eye of the needle found in the neck of the deceased may not have been pierced by a needle?" Teacher Jin said.

"You mean...... Is the eye of the needle just an illusion? Li Zhitong said.

"This assumption needs to be focused on, if the murderer is a thoughtful person, then the murderer should use blindfolds to ensure that he is not suspected after committing the crime." Teacher Jin said.

"But this assumption is a bit too ridiculous, and when the deceased fell, I saw with my own eyes that the deceased's neck was blackened, and judging from the area of the deceased's skin that had darkened, the needle's eye was the center point." Li Zhitong said.

"Let's do the autopsy! The autopsy must have been better than the others downstairs. Teacher Jin said.

"Then go down and bring the corpse on board!" Li Zhitong said.

"Let's go down together, I can continue to pretend to be paralyzed." Teacher Jin said.

"There's no need, right? Now that Kang Yuliang is the only one left, do we need to be afraid of him? Li Zhitong said.

"Just be careful in everything, I think it's necessary to pretend to be paralyzed, sometimes pretending to be sick can make the enemy take it lightly." Teacher Jin said.

"Whatever you want! Anyway, I won't go down, you can go downstairs for an autopsy alone! Li Zhitong said.
