"It should have been brought in by Li Tao himself, and the probability of putting it in the hotel room in advance should be very low. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 info" Mr. Jin said.

Xu Tian suddenly thought of something, put it in the hotel in advance? It's like I've experienced it before.

"No, this method is not impossible, if it is placed in a hotel room, then every room must be put with a poison needle, because which room Li Tao will be placed in is not up to the murderer." Xu Tian analyzed.

The two hurriedly broke into other rooms of the hotel, but fortunately, the county police had not left at this time, and Mr. Jin immediately mobilized everyone to search the hotel room.

After half an hour of intense searching, police officers found a poison needle in the corner of the hotel.

The poison needle is placed under the carpet in the corner of the hotel, and the poison needle is inserted in the carpet, if you don't look carefully, even if you open the carpet, you can't find the poison needle.

Xu Tian's mood was very apprehensive, and this uneasy feeling made Xu Tian feel very heartbroken.

"What do you think?" Teacher Jin said.

"Don't look at it, the truth is already in front of you, and only that person can do this kind of thing." Xu Tian said.

"But this alone can't prove the murderer, because the murderer has an excuse to enter all the rooms, and have you found out the methods used to induce Fang Lu and Li Tao to commit suicide?"

"There are a hundred ways to do it, as long as the excuse is reasonable, let the person believe his words, and the person who can do it can only do it with that person."

Teacher Jin seemed to understand Xu Tian's words, and at this time, Teacher Jin couldn't continue, so he had to leave silently and return to the conference room.

Xu Tian was in a very bad mood, after all the cases were connected together, the conclusion of who the murderer was was already very clear, but Xu Tian had no evidence, which was the most deadly.

Seeing that the sun is about to go down, if you don't find out the murderer quickly, I'm afraid there will be no chance.

"Xu Tian, why are you here? Everyone is getting ready for dinner. ”

Sitong's voice came from behind, and if he hadn't heard Sitong's words, Xu Tiandu would have forgotten what he was here for.

"Sitong, where have you been this afternoon?" Xu Tian asked.

"Huh? I've been waiting for you in the conference room, and you've been back to the conference room several times, and you've greeted me, don't you remember? ”

Xu Tian really didn't remember, there was nothing else in Xu Tian's eyes in the case, and now for Xu Tian, nothing was more important than finding evidence.

"By the way, Sitong, there is one thing I have always wanted to ask you, did you already know the identity of Teacher Jin?"

Faced with Xu Tian's sudden question, Sitong felt very panicked.

This day has finally come, and Sitong is also struggling, how to make it clear to Xu Tian?

"I went to your house the night I solved the murderer on campus, and Mr. Jin was in the bathroom at that time, right?"

"How do you know?" Sitong covered his mouth after speaking.

"Because of the soil, the soil of the flower pot is not the same as the soil stepped on outside, and there was no fragrance on Siyan's body in the house at that time, but there was a smell of soot, except for Teacher Jin who could make Sitong lie, there would definitely be no one else."

"If you knew it then, why did you ask me now?"

"Because I've been observing what you guys want to do, it's no accident that you called me here this time, to be honest, I suspected Mr. Jin at first, because his whereabouts were too mysterious, but when I finally identified the murderer on campus, Mr. Jin had to show his hole cards, and from that time on, the stone that was calm in my heart finally fell. But I don't understand why even Sitong was involved. ”

"That's because ......"

"Because of Siyan? Siyan's identity as a teaching assistant also made me suspicious, because I never saw Siyan prepare the information of the teaching assistant at home, but Siyan has been making her room mysterious, out of politeness, I have not entered Siyan's room, but I can also detect that Siyan has a big smell of smoke on her body every day when she comes back from work, that kind of cigarette is a relatively cheap cigarette, and it is very familiar, it is the smell of the police station. Siyan goes to work at the police station every day, so Siyan's identity is already obvious, she is a police officer. But why hasn't Si-yeon ever told me the truth? ”

"That's because we want to see what you're really capable of." Teacher Jin walked over from behind and said.

"My strength?" Xu Tian asked in surprise.

"It was Siyan who recommended you to us, and at the same time there is Lao Chen as a guarantor, I have heard a lot of your deeds from Lao Chen, whether it is the suicide of a bail prisoner or the ghost incident in the desert, it makes me very interested in you. But what surprised me the most was the case you solved in your hometown, to be honest, with the help of Sitong, there were really few clues in that case, and you could still detect the truth about the identity swap of the red sister in that situation, which is really commendable. ”

"So you want to test if I have the strength to fight against the old man?"

"No, your strength doesn't need to be tested, what we want to test is whether you can protect yourself, and ......"

"Also, once I get involved, my life may change in the future, and once I step into this troubled water, I can't get out, right?"

"That's right, Siyan contacted us after you left the village, and at that time, Siyan recommended you to the case handling team, and Lao Chen tried his best to protect you, but you are not from our police after all, and it is not something that Lao Chen and Siyan can finalize if they want you to participate, but we really need people like you to help us fight against Zhinian Tai Sui."

"I understand, from the moment I left the village and received a call from Li Ming, I was already in your calculations."

"I can't say that I calculated, because Tian Huizhen and Li Rinrin's cases are true, it's not that we are cheating, nor are we designing an unsolved case, but it just happened to let you run into it, and their case happened to have something to do with Zhinian Tai Sui, we will plan it, and we will involve you."

"This kind of thing was good for me at the beginning, and the most hated thing for me as a person is deception."

"I didn't deceive you, Siyan's identity is a police detective, she can't reveal her identity in front of outsiders, even her family, but Siyan still couldn't hide Sitong."

"I won't pursue you for the time being, since I've been involved, I will definitely not let you down, but don't deceive me again in the future, we should be able to go back tonight, there are still very difficult cases waiting for me in Dong'an City, right?"

"I'll talk about it later, and now you can solve the case here."

"Oh well! Now that everyone has finished eating, let's gather everyone to the conference room! ”
