Yu Chihong had already guessed what he was going to say, what he said to Qiao Yan in Qiao's Mansion tonight, he hid at the corner of the stairs and listened to it word for word. "Come into the house and talk about it." He was calm.

Pushing the door into the living room, a room of cold air enveloped them.

"I'm telling you that I want to pursue your girlfriend." Before he sat down, Zhong Kai opened his mouth bluntly.

Although it had been expected for a long time, after hearing Zhong Kai say it with his own ears, Yu Chihong still felt that his entire chest cavity was contracted, his throat seemed to be pressed and choked, and he couldn't make a sound at all.

"I didn't mean to snatch a woman from you." Zhong Kai explained with some difficulty, "For so many years, I haven't considered remarrying, but Qiao Yan made me think of this for the first time. I myself think it's incredible that I would fall in love with your woman. Qiao Yan really made me very excited, but if it was just heartbeat, I wouldn't do it. What's more, she is genuinely good to Babe, and I believe she will be a good mother. ”

Yu Chihong took a big breath. "You mean you want me to give her up to you? I'm sorry, Qiao Yan is not an object, she is a person with thoughts and feelings. ”

"It's not Jean, I'm going to compete with you." Zhong Kai seemed to be issuing a challenge declaration, "I know that a divorced man like me can't compare with you." But I still want to do my best, for the sake of Beibei, and for myself, otherwise I won't be reconciled. ”

Yu Chihong held his forehead with his hand, feeling hazy in front of his eyes. A feeling of pathos and helplessness conquered him, and his eyes moistened.

"As long as you're not married, I'll fight to the end." After Zhong Kai repeated his declaration, he left without looking back.

Yu Chihong sat on the sofa, hung his head weakly, and closed his eyes in a gloomy manner. After a long time, he got up to pour himself wine, he didn't remember how many glasses of wine he drank that night, and then he fell on the sofa drunk and hazy, and recalled in a daze that he had kissed Qiao Yan here, such an emotional and lingering kiss.

Tossing and turning, he kept moaning and calling Qiao Yan, and then, he fell asleep, and almost immediately dreamed of Qiao Yan, she was floating in the clouds, he wanted to hug her, but the clouds covered her, her body and the clouds and mist blended together, turned into clouds, and floated away into the ethereal firmament. He struggled in fright and shouted loudly: "Qiao Yan, don't go!" Don't leave me! ”

He awoke, the room was empty and silent, and the dawn had illuminated the window, revealing a misty gray. He sat up, his mind drowsy, the reality and the dream so mixed that he couldn't separate them for a moment. He sat on the couch for a long, long time, until the door was pushed open, and he woke up and looked at the door.

Left Bank walked in, she had come to clean up. When she saw Yu Chihong, she was surprised. "Mr. Wei Chi, did you sleep here last night? On such a cold day, you will freeze and catch a cold, I will go and cook you a bowl of brown sugar ginger soup to drink. ”

"No need." Wei Chihong thinks that his physical fitness is very good, and he doesn't get sick so easily, "What time is it?" ”

Left Bank said it was half past seven.

"My brother ......," he paused before asking, "what is he doing?" ”

"Mr. Zhong went to pick up Beibei, Beibei stayed at Miss Qiao's last night." Left Bank replied.

Wei Chihong rubbed his swollen temples, got off the sofa, and walked towards the door of the living room with heavy steps.

"What would you like for breakfast?" Left Bank asked.

"I don't want to eat it." Wei Chihong drank too much wine last night, and slept in a cold environment all night without any cover, and now he has a headache and dizziness, and his stomach is uncomfortable, and he has no appetite at all. He went upstairs to the bathroom of his room to wash up briefly, took out his camera, imported a photo into the computer, copied it into a USB flash drive, changed his coat and went out.

He went to the Public Security Bureau, and today is Sunday, but for him there is no concept of a holiday at all, not to mention that he still has an important thing on his mind. On the way, he called Wan Xing and asked her to come to the Public Security Bureau.

When he arrived at the Public Security Bureau, he went directly to the autopsy room on the seventh floor, and Li Shuhua was busy all night last night.

Lü Bin arrived at the autopsy laboratory earlier than Wei Chihong, and he was mainly responsible for investigating Professor Zhuang Yiqun's case.

Li Shuhua was wearing a white coat and a mask. After breaking her teeth that night and being discovered by Li Haoxun, she basically never took off her mask in the Public Security Bureau, her teeth have not been repaired, her image is not good, and she does not want to be seen again, so as not to cause unnecessary speculation.

"The results of the autopsy came out, and it was aconitine poisoning that caused death. It is the poison of aconite, and there is a great possibility of poisoning. Li Shuhua was still wearing a mask when she talked to Wei Chihong, only revealing a pair of narrow eyes, "The toxicity of aconitine takes effect quickly, and it can kill people in a maximum of 30 minutes after entering the human body." ”

"So, the prisoner was someone who had contact with the victim within 30 minutes before his death?" Yu Chihong asked.

Li Shuhua nodded.

"Several researchers who were with Professor Zhuang at the time had thoroughly investigated and found no problems." Reporting on the results of the investigation so far, "It has also been ascertained that before Professor Zhuang's death, he had a video conversation with foreign experts for more than 40 minutes to discuss research questions, and the whole process was videotaped." In other words, Professor Zhuang did not eat or drink anything in the 30 minutes before his death. I've made a copy of the video, so you can take a look. ”

After watching the video, he had to go to the forensic science and technology laboratory next to him, and when he was leaving, Li Shuhua called out to Yu Chihong. He then asked Lu Bin to wait in the forensic science and technology laboratory first, and stayed by himself.

"My uncle...... Did I look for you? Li Shuhua suffocated through the mask and made a muffled voice.

Yu Chihong looked at her, which was considered a tacit acquiescence.

"If he ......," Li Shuhua's voice was harsh and hoarse, "if he said something to embarrass you...... I apologize to you...... That's not what I meant......"

"He didn't embarrass me, and you don't need to apologize." Wei Chihong interrupted her.

Li Shuhua's eyes looked at Wei Chihong sadly, her lips hidden in the mask trembled, and she asked in a low voice, "...... Can it still be the same as before? ”

"Of course," Wei Chihong tried to keep his tone as calm and indifferent as possible, "I don't think there will be any kind of change. ”

"That's good." Li Shuhua turned around and didn't let Yu Chihong see the tears that had poured into his eyes.

Wei Chihong looked at her slightly trembling back, his heart was a little sour, and he wanted to comfort her, but he didn't know how to speak, after all, he just asked, "Are your teeth better?" ”

"Two more times, I'll have to wait until I have time." Li Shuhua didn't turn around, "Thank you for introducing me to Doctor Xie." ”

"You're welcome." Wei Chihong felt quite uncomfortable in her heart, he was the culprit who caused her to break her teeth, but she thanked him, which seemed a bit ridiculous. But he didn't like to drag the mud and water, so he walked away.

Li Shuhua had been standing there, two lines of tears sliding down the corners of her eyes, hidden in the mask.

There were only Cao Chongshan and his assistant Lai Feng in the forensic science and technology laboratory, and the two were busy with other cases, and Cao Chongshan didn't even have time to complain. Wei Chihong watched the video from beginning to end, and indeed did not find the slightest suspicious place. So how aconitine entered Professor Zhuang's body has become a difficult mystery to solve.

In addition, Lu Bin also got the surveillance video inside and outside the laboratory where Professor Zhuang was that day. Zhuang Yiqun's time of death was 14:23 the day before yesterday, and he went to work at about 12 noon that day, and held a meeting with people from the pharmaceutical company in the conference room, which started from early 12 to 1 o'clock, and has been working in the laboratory since then. In another case, according to several researchers, Professor Zhuang had a laptop and a desktop computer, but the laptop was not found, and someone thought it had taken it. ”

"What kind of pharmaceutical company guys?" Yu Chihong asked.

Lu Bin said that it is Haidu Ruixin Pharmaceutical Co., Ltd., which is a subsidiary of Ruixin Company, a Fortune 500 company, in China. Zhuang Yiqun is an external expert at the company.

The two watched the surveillance video from beginning to end and found no problems.

Soon after, Wanxing arrived. Wei Chihong asked her to analyze the surveillance video from beginning to end, Wan Xing didn't have any extra words, opened the laptop and started working.

"Part of the surveillance footage has been altered." After repeated viewing and analysis, Wanxing finally discovered the flaw. She rewinds and verifies from the video footage of the night before Professor Zhuang's murder that at one o'clock in the morning, security guards entered the laboratory to inspect the scene, and the picture did not look special. But if you lock on to an area behind you, you will find that there is a faint moonlight shining through, from this angle, there should be a window on the left, and after adjusting the brightness of the light, you can see the changes in the light and shadow in the picture, and the modification is so clever that it is difficult to be noticed.

Wei Chihong nodded and said, "This video is connected to the security company, and someone should have hacked into the network." ”

Wan Xing checked the parts that might have been modified again, from 1:35 a.m. to 1:55 a.m.

"Late at night the day before Professor Zhuang was killed, someone may have infiltrated the lab and stole Professor Zhuang's laptop." Wei Chihong speculated, "There must be some important documents in the laptop." ”

"I'll talk to someone from Ruixin Pharmaceutical." After Lu Bin finished speaking, he was about to leave, but Wei Chihong called him and said that he would go to Ruixin Pharmaceutical Co., Ltd. with him in the afternoon, and Lu Bin would go to do other things first.

"Is there anything else you want me to do?" Although Wan Xing is not very friendly to Wei Chihong, he treats his work very seriously and conscientiously.

"The modified surveillance video, you continue to track it down, try to find out who modified it. Now let's analyze a few photos first. Yu Chihong took out the USB flash drive from his pocket and copied the three photos into Wanxing's laptop.
