Yes, Yu Qianqian is committing suicide, she doesn't even want her life, she really doesn't need to lie to herself.

Chen Weibin thought for a while and asked, "That'...... Do you still have the impression that on the first night of Zhou Yuanliang's death, what did he eat and drink? ”

"Zhou Yuanliang had a stomach ulcer in those two days and had a bad appetite. That night, when I was having dinner at the Mio-Bin Hotel and Jinjincai, I remember that Zhou Yuanliang only ate very little and drank a little soup. Later, when he arrived at the Nangong nightclub, Zhou Yuanliang didn't eat anymore, only drank some water. ”

"Oh? Drinking only a little water? Chen Weibin repeated with some vigilance.

"Yes. Moreover, he did not drink the water in the private room at all, he drank the water from his own cup. ”

"Cups? Does he still carry a water glass with him? Chen Weibin asked.

"I didn't carry it with me before, wasn't it a stomach ulcer in those two days, he put some stomach-nourishing tea in the cup, and asked the driver Zhao Xiaojiang to take it with him all the way."

"Where did the water in that cup come from? Is it from Liangdong Group that it was packed and brought out, or is it the water that was picked up at the Miobin Hotel, or the water that was picked up at the Nangong Nightclub? Is it Zhou Yuanliang himself who received the water, or the driver Zhao Xiaojiang who received the water? Chen Weibin asked a series of questions.

"These ...... I really didn't notice. Yu Qianqian shook her head, and then suddenly said, "By the way, I have a little impression that after Zhou Yuanliang and I came out of the Miobin Hotel and got into the car, Zhou Yuanliang sat in the right back seat, and he said a word at that time." ”

"What did he say?"

He said that there was no water in the cup, and asked Zhao Xiaojiang to fill the cup with water later, and then take the cup to the private room of the nightclub for him.

"Where did Zhao Xiaojiang pick up the water?" Chen Weibin asked.

"I don't know."

Chen Weibin nodded, then looked at the wall clock on the wall, it was already one o'clock in the morning, and said to Yu Qianqian: "Let's go back." You...... Stop doing stupid things! ”

Yu Qianqian smiled bitterly and said slowly: "Seriously, Chen Weibin, I hate you very much, I fell to the end of today, all thanks to you!" But...... I still have to thank you for saving my life! ”

Chen Weibin smiled, didn't say anything, called the police from the detention center, took Yu Qianqian away, and then left the interrogation room with Wu Lei and went home.

Chen Weibin tiptoed into the house, washed up briefly, set an alarm on his mobile phone, and then went directly to sleep on the sofa in the living room. However, after tossing and turning, I couldn't sleep for a long time. Unexpectedly, the investigation work has become more and more blurred instead of becoming clearer and clearer. If Yu Qianqian was telling the truth, she had only made a mark on a refill, and the refill in the weeds happened to have the same mark, so there was a chance that it would be ...... The snake venom refill in the weeds was the one that Yu Qianqian gave to Zhou Yuanliang, but for some reason, the snake venom refill was thrown out by Zhou Yuanliang. In this way, Yu Qianqian is not the direct real murderer who poisoned Zhou Yuanliang, so ...... Who is the murderer?

Chen Weibin turned over on the sofa again. How did the snake venom in Zhou Yuanliang's stomach get in? Judging from Zhou Yuanliang's trajectory, there is a possibility of poisoning in three places. One is at the Miohama Hotel, where it is possible to be a golden talent, or a staff member of the hotel. However, the time was not right, at nine o'clock that night, when Zhou Yuanliang came out of the Miobin Hotel, there was no water in the cup, and the time of his death was at one o'clock in the morning of the next day, it was already four hours, and that day I heard the detachment's forensic doctor Lei Ming say that after the king cobra venom entered the human bloodstream, within three hours, it would definitely cause death, therefore, the Miobin Hotel could be ruled out.

Another place is the Nangong nightclub, Yu Qianqian said that Zhou Yuanliang did not drink the water in the private room at all. That...... Zhao Xiaojiang, the driver who went to pick up the water, was a major suspect. However, Zhao Xiaojiang has been missing and has not been able to obtain a confession. In addition, Yu Qianqian said that Fan Li was ready to let Zhao Xiaojiang be a substitute for the dead ghost, if Zhao Xiaojiang was part of their group, how could they be used as a substitute for the dead ghost? However, it cannot be ruled out that Zhao Xiaojiang is one of them, but he was used, and he will be killed after the fact, but he himself is kept in the dark.

The last place is Zhou Yuanliang's villa. In Zhou Yuanliang's villa, except for Zhou Yuanliang, there is only the nanny Wang Cuiping. Zhou Yuanliang's suicide has been ruled out, could it be Wang Cuiping's hands and feet in the villa? He and Wang Cuiping met twice in total, once in Zhou Yuanliang's villa, in a hurry, and the other in the criminal investigation detachment to inquire about the situation. Judging from Wang Cuiping's expression, she was panicked excessively, but she couldn't see any clues, and the morning before yesterday, she also called Wang Cuiping and asked her about the situation, which shows that so far, she has not escaped. Also, if she is really Fan Li and their gang, her identity is Zhou Yuanliang's nanny, and it is very convenient to poison her, why do Fan Li and them still need to find Yu Qianqian, and they have to go to great lengths to design a serial plan? However, none of the evidence involves Wang Cuiping, the only suspicion is that the plug of the refrigerator has fallen off, if it turns out that it was really Zhou Xianqing's doing, then Wang Cuiping's suspicion can be ruled out.

Early in the morning, Chen Weibin was woken up by the alarm on his mobile phone, so he immediately got dressed, rushed to the sub-bureau, found Tao Chunqiang, and then the two went to Fei Yuanda's office together.

Sitting on the sofa in Fei Yuanda's office, Chen Weibin reported his recent work and his thoughts to the two leaders in detail.

After listening to Chen Weibin's report, Fei Yuanda stood up and paced back and forth in the office.

"Fei Bureau, Tao Bureau......" Chen Weibin wanted to speak and stopped.

"Wei Bin, you say, don't have any worries!" Fei Yuanda stopped, looked at Chen Weibin and said.

"I suggest that we not report to the high bureau for the time being regarding the new discovery of snake venom refills!" Chen Weibin said slowly.

As soon as Chen Weibin finished speaking, Fei Yuanda and Tao Chunqiang were a little surprised.

Chen Weibin continued: "Although we found snake venom refills in the weeds, we were unable to extract fingerprints from them, so we could not determine who had touched them. Also, Zhou Yuanliang has died, Zhao Xiaojiang's whereabouts are still unknown, if you want to prove that the refill is the one that Yu Qianqian gave to Zhou Yuanliang, only relying on the mark on the refill to corroborate, the convincing power is not strong, and we can't confirm it from the evidence. ”

Fei Yuanda and Tao Chunqiang nodded.
