"Can I invite a few more people?" Qiao Yan thought that this was the best occasion to introduce Qiao Ran and Lu Bin to each other, she was a person who believed in her word, but she didn't want Lu Bin and Qiao Ran to have anything to do, that kind of noisy occasion, the best acquaintance was like a glimpse. I just don't know if Lu Bin will be free.

"Absolutely." Hai Haoyi agreed very happily, "There are a few people in total, let Yuqing tell me in advance, and I will send you an invitation." ”

Qiao Yan glanced at Mo Yuqing, wanted to laugh and endured it, Wan Xing had already chuckled.

"What are you laughing at!" Mo Yuqing and Wan Xing were next to each other, and she chirped in a voice that only Wan Xing could hear.

Wan Xing also suppressed his voice: "That 'Yuqing' is so affectionate." ”

Hai Haoyi noticed that Wan Xing's laughter was related to him, and his ears were slightly hot. "I'll go first." His soft eyes quietly swept over Mo Yuqing's face, "I hope you can all enjoy it then." ”

Several people said that they would fight for the past.

"Are you going to a cocktail party?" After Hai Haoyi left, Mo Yuqing asked.

"If we go, will it get in your way?" Zeng Jinling asked rhetorically, "To be honest, don't treat us as outsiders. ”

"Of course it won't get in the way, it would be embarrassing if I went alone." Mo Yuqing's tone was sincere, "It's rare to have such an opportunity, let's go and have fun together." ”

"Wanxing is going?" Zeng Jinling asked again, she knew that Wanxing didn't like to participate in group activities, and it was rare that she was willing to come over for dinner today.

Wan Xing hesitated slightly and nodded. "It's good to go and have fun, or it's boring to be alone on Chinese New Year's Eve."

Qiao Yan raised her eyes and looked at Wan Xing, she had changed a lot, she began to integrate into the collective, and she had a sense of belonging to the special investigation team.

In the afternoon, Wei Chihong and Lu Bin went to Ruixin Pharmaceutical Co., Ltd. together. Zhuang Yiqun went to work at about 12 noon on the day of his death, and held a meeting with Ruixin Pharmaceutical people in the conference room, which started at about 12 o'clock and ended at 1 o'clock.

"Did Professor Zhuang eat from 12 noon to 1 o'clock that day?" Lu Bin asked.

Deng Xiaolong, a member of the research and development department of Ruixin Pharmaceutical Co., Ltd., was mainly responsible for receiving and responding to inquiries, and he was responsible for bringing people to the school for a meeting with Professor Zhuang that day. The man was in his thirties, wearing a pair of black-rimmed glasses, a mustache, and a loose expression. "When you eat, it seems that we only have our company's nutrients. It is the latest product and was given to Professor Zhuang for tasting. ”

Yu Chihong's eyes staring at Deng Xiaolong immediately became sharp.

"However, the ingredients are amino acids and vitamins, and there is nothing special about them." Deng Xiaolong added.

"When did you take it?" Lu Bin asked again.

Deng Xiaolong thought about it and said, it was when the meeting was about to end, almost 1 o'clock.

"Can you bring us the same bottle of nutrients?" Lu Bin made a request.

Deng Xiaolong said yes and asked the other staff next to him to get it.

The nutrients were canned, and the staff quickly brought in a few cans and gave one to each person present. Deng Xiaolong opened a can by himself, raised his head and drank it, and everyone else drank it too. Wei Chihong and Lu Bin didn't drink it, and took the two cans of nutrients back to the Public Security Bureau.

After Cao Chongshan's inspection, he confirmed that the ingredients were substances such as amino acids and vitamins, and there was no problem.

"Assuming that only the jar of nutrients that Professor Zhuang drank is problematic, but he drank it 90 minutes before he died. The toxicity of aconitine takes effect very quickly, and it can kill a person in a maximum of 30 minutes after entering the human body. It doesn't make sense. In the forensic science and technology laboratory, Wei Chihong was puzzled.

"I'm only responsible for giving you the test results, and nothing else can help you." Cao Chongshan put on a gesture of helplessness.

"I've made some discoveries here." It is also reported by Wanxing in the laboratory. After having dinner with Qiao Yan and them at noon, Wan Xing returned to the Public Security Bureau and continued to investigate the modified surveillance video. "When the person who modified the surveillance video invaded the security company's network, he passed through thousands of servers at home and abroad, although it may be accidental, but several of these servers are the system of the same company, and this company is Ruixin Company."

Ruixin is one of the world's top 500 companies, headquartered in the United States, one of the 50 largest companies in the United States, and is also listed as one of the world's most powerful pharmaceutical manufacturers. The company has more than 170 branches and 230 offices in 55 countries and regions around the world, 200 subsidiaries in 54 countries around the world, more than 112,000 employees around the world, and its products sell well in 175 countries around the world. Haidu Ruixin Pharmaceutical Co., Ltd. is its subsidiary in China. ”

"Wei Chi, Professor Zhuang's blood test results are out." Li Shuhua hurriedly came, "Tetrodotoxin was found in the blood. ”

"Fighting poison with poison, it's too clever." Cao Chongshan actually praised it.

"It turned out to be the antagonistic effect of the poison." Yu Chihong suddenly realized, "Puffer fish is highly poisonous and can inhibit the toxic effect of aconitine." Taking two poisons at the same time, the poison and the poison compete with each other, which can temporarily suppress the toxicity. The concentration of puffer fish poison in the blood reaches half, and it takes less time than aconitine, so a time interval can be created before the onset of toxicity. ”

"If the premise is antagonistic, what will happen to the timing of the criminal's murder?" Lu Bin humbly asked for advice.

Li Shuhua calculated that it should have been poisoned 90 minutes ago.

This overturns the previous alibi, Zhuang Yiqun did not eat within 30 minutes before he died, but 90 minutes before his death, he drank the nutritional test drink of Ruixin Pharmaceutical Co., Ltd., and there must be something wrong with the can of nutrition! Unfortunately, those empty jars must have been disposed of long ago and cannot be used as evidence. Wei Chihong's eyes were cold, "The people who had a meeting with Zhuang Yiqun that day should all be investigated in detail, especially that Deng Xiaolong." ”

In the evening, Qiao Yan went back to Qiao's Mansion for dinner, and she was surprised to hear that Bei Bei was still at home. Aunt Axiu told her that Zhong Kai came to pick up Bei Bei in the morning, but Bei Bei refused to leave, and she had to make chocolate with Qiao Ran's sister, and Zhong Kai still had to go to work, so she had to send Bei Bei here, saying that she would pick her up after work in the evening. Qiao Ran played with Bei Bei for a day, and only went out in the evening, she had to have dinner with her friends from the church youth choir, and then rehearsed.

Aunt A Xiu also reported that Wei Chihong invited someone to install the 110 area anti-theft network alarm system, and it is said that when encountering illegal incursion, users can transmit the alarm signal to the 110 command center in time through the installed 110 area anti-theft network alarm system equipment. After receiving the information, the center will immediately arrange for the patrol force of the police station in the corresponding jurisdiction to rush to the scene. It is equivalent to an extra "electronic police" at home, which not only stands guard day and night, but also immediately reports to the 110 command center after discovering the "enemy situation".

The tenderness that moved Qiao Yan's heart was aroused, and Wei Chihong really did what she said and cared about her. The thought of the evening date made her heart beat faster.

Aunt Xiu didn't have time to accompany Beibei, she stayed alone in Qiao Ran's room. Qiao Yan walked into the room and saw Bei Bei curled up in the corner of the bed, holding a HelloKitty doll in both hands. She sat there lonely, shrunken, thin, with her little knees hunched, her chin resting on the doll's head, a pair of big eyes, open for a moment, her hair scattered on her face, and her cheeks were streaked with tears.

"Beibei, why are you crying?" Qiao Yan asked with pity and concern. I was a little worried, but don't feel that I have been wronged, go to my father to complain.

Bei Bei looked up at her, her lips curled and she wanted to cry. "No one to play with." She said softly that now she is just a lonely and helpless little girl.

Qiao Yan sighed in her heart, even if she is a little witch and a little tyrant, she is actually just a little child. "Sister Qiao Ran has something to go out, and Aunt Ah Xiu is busy cooking dinner. Now that I'm back, I'll play with you. She reached out to touch Mobei's shoulder, and after stroking it, she found that she was only wearing a Qiao Ran's pajamas, without a quilt, and the quilt was messily piled aside. Have you been playing in bed with Sister Qiao Ran in the afternoon? ”

Bei Bei said yes, and she has been in bed since she woke up.

Qiao Ran is young after all, where does he know how to take care of children, and he forgot to change Bei Bei into warm clothes when he left.

At this time, she vaguely heard the doorbell ringing, Qiao Yan thought it was Wei Chihong coming, and she was overjoyed, so she quickly changed Beibei's clothes and took her downstairs. After arriving in the living room, he found that the person who came was not Wei Chihong, but Zhong Kai.

"I'd like to invite you out to dinner, okay?" Zhong Kai sent out an invitation as soon as they met.

"I'm sorry......" Qiao Yan was about to refuse, Bei Bei suddenly sneezed twice, and then, she quietly grabbed the hem of Qiao Yan's clothes with her little hand, pulled it gently, and called "sister" in a low and soft voice. Qiao Yan's heart was pounding, this "sister" was so sweet, so gentle, like a thin thread pulling from her heart, awakening all her feminine gentle instincts.

She let out a long sigh, bent down, and reached out to touch Beibei's head.

"It's just a meal." Zhong Kai took the opportunity to say, "You take care of Bei Bei so much, I just want to express my gratitude to you." ”

Zhong Kai said very sincerely, Qiao Yan was embarrassed to refuse, maybe she was too careful, he said last night that he wanted to fight, but it was just an impulse. After hesitating, she glanced at it and saw Yu Chihong standing at the door of the living room, looking at her quietly.

Qiao Yan immediately left Bei Bei and Zhong Kai and ran to Yu Chihong. "When did you come?" She grabbed his arm, she deliberately wanted Zhong Kai to see their intimacy. Unexpectedly, Yu Chihong gently pulled his arm away.

Qiao Yan didn't expect Yu Chihong to be like this, her expression was a little embarrassed and a little embarrassed.

"You go to dinner with them." Yu Chihong suppressed his heavy breathing.
