At 4:30 a.m., Jinping Police Office.

Zhao Yu did not break his promise and indeed brought Cui Lizhu here. When Cui Lizhu saw Zhao Yu enter the police station, she was immediately depressed!

What surprised her even more was that after seeing Zhao Yu's pass, the police officers on duty in the police station all looked in awe, as if they were treating their leaders.

Although Choi Lizhu was tied with a rope, it seemed particularly weird, none of these police officers dared to ask carefully.

It was not until Zhao Yu took her into the office that a handsome young man finally asked: "Team leader, you are..."

"Don't talk about these things for now," Zhao Yu asked Cui Lizhu to sit on a chair beside her, then quickly came to Zeng Ke and asked, "How is it? What's the clue you said?"

"Oh..." Zeng Ke hurriedly turned on his computer and said to Zhao Yu, "Team leader, I have checked the third deceased in detail, right..." He pointed the computer screen at Zhao Yu, "The deceased is named Zhang Kaibin, and he is the deputy director of the quality inspection department of Changxin Longtai Pharmaceutical Factory. He has just been brought up.

"That night, I almost found out all his ancestors' eight generations," Zeng Ke said excitedly, "This person has good interpersonal relationships. Not to mention in a pharmaceutical factory, even in life, he has basically never had any conflicts with others.

"However, after I carefully investigated his resume, I suddenly found something wrong!"

As he said that, Zeng Ke smiled mysteriously and said to Zhao Yu: "Team leader, you see, Zhang Kaibin graduated from Zhangzhou Medical University. He studied clinical, not medicine. And... You see, I listed all his transcripts when he was in school. His grades are really poor. No wonder he did not work in the hospital after graduation, but came to the pharmaceutical factory!"

"Well..." Zhao Yu looked at Zeng Ke strangely, wondering why he wanted to take out the transcript.

"Team leader, look at his resume again," Zeng Ke said excitedly, "Before he was appointed as the deputy director of quality inspection, he was transferred from the R&D department. Because he developed a best-selling new drug, chloraminetopine, he was promoted and paid a salary increase!

"But I checked his records in the R&D department. He has always been unknown in the R&D department. And with his poor grades when he was in school, he didn't even have the qualifications to stay in this team!"

"Wow! Chloramine Topine? I've heard of it!" Unexpectedly, when Cui Lizhu next to her suddenly felt excited, "This is a psychotropic drug with the least side effects at present! It costs more than 500 yuan per box! It's much more expensive than butyrylb!"

"Shut up, you don't speak, no one knows you are crazy!" Zhao Yu said black.

"Ah? Crazy?" Zeng Ke was startled. Looking at the beautiful woman tied up, he swallowed his saliva and said to Zhao Yu, "Team leader, why don't you use handcuffs?"

"You don't talk nonsense, hurry up!" Zhao Yu pointed to the computer and drank to Zeng Ke.

"Oh, although this new drug is expensive, it has a very marketable market. Once the research and development is successful, the orders are full, and even abroad is no exception!" Zeng Ke said quickly, "This time Changxin Longtai can be listed and launched abroad, and this new drug is also one of their points-gaining projects!

"The team leader, what's wrong is that the development of this kind of spiritual new drug is generally a very long process, at least 8 years!" Zeng Ke pointed to the victim's photo, "But Zhang Kaibin has been working for less than 5 years! Although it's just a name, the development of new drug is no better than an academic paper. This is a big event that can be left in history, so I think... there must be something tricky here!"

"Oh?" Zhao Yu said after thinking seriously, "What do you mean is that someone who is not convinced that Zhang Kaibin's name was written on the new drug development list and poisoned him?"

"It's possible, it's even better than this!" Zeng Ke said, "I've checked it. In addition to Zhang Kaibin, the names of Lu Xiaohong and Peng Ankang are also on the R&D list!"

"Ah?" Zhao Yu was suddenly shocked. Lu Xiaohong and Peng Ankang were the second and first victims of this rapid murder case. "So... the murderer was based on this list..."

Bang...

When Zhao Yugang said this, the office door was suddenly pushed open, but when he saw Wu Xiumin running in from outside in a blink of an eye:

"Team leader, team leader, I found it, I found it... well..."

Suddenly, Wu Xiumin saw Cui Lizhu, who was confused, and she was stunned. She was stunned and looked at Cui Lizhu directly, and asked, "What's the situation? Is this the murderer?"

"No, I'll explain to you again. Hurry up, what have you discovered?" Zhao Yu asked hurriedly.

"I...oh..." Wu Xiumin then remembered the serious matter and said hurriedly, "I will investigate the second deceased Lu Xiaohong. She is a senior technician in the R&D department of the pharmaceutical factory. This woman was promoted to senior technician less than a year after she came to the pharmaceutical factory to work. It seemed a bit unusual!

"So, I have been investigating her interpersonal relationships all day today, and I have almost searched all of her colleagues. As a result, I discovered a shocking secret!"

"No way?" Zeng Ke was surprised, "Sister Wu, the police have investigated them many times. If there were big secrets, they should have known it long ago, right?"

"Hahaha..." Wu Xiumin said proudly, "This is the time for our psychologists to play a role! When I investigated, I found that among the deceased colleagues, there were a few people who reacted abnormally. They were nervous, anxious, and afraid, as if they were overly worried about something besides Lu Xiaohong's death!

"So, I focused on taking care of them, and in the end... guess what did I find?"

Wu Xiumin's confusion suddenly aroused everyone's curiosity, and even Choi Lizhu next to her stretched her neck and listened with her ears.

"I used a secret method to hypnotize one of them quietly!" Wu Xiumin said with his eyes flashing, "While he spoke vaguely, although he spoke vaguely,... I still heard something!"

"Hypnosis?" Zeng Ke was surprised, "You..."

Zhao Yu was not shocked, because Wu Xiumin's resume had shown that she had hypnotic specialties.

"It's no big deal!" Wu Xiumin said proudly, "As far as he wants, what he is concerned about should be related to a new drug developed by their R&D department. It seems... the doctor was always responsible for the development of new drug at that time, but for some reason, when the new drug was about to pass the review, the man suddenly resigned!

"I suspect that the entire rapid murder case is probably related to this matter!" Wu Xiumin said, "I checked the information and found that in addition to Lu Xiaohong, the other two deceased also worked in the R&D department during their lifetime! So..."

"Doctor? New Drug?" Zhao Yu widened his eyes, feeling that he had found the key to solving the case.

"However, I investigated the records of the pharmaceutical factory, but I don't know why," Wu Xiumin said with a frown, "I didn't find the doctoral information about developing new drugs!"

"This..." Zeng Ke said, "If I could go to the pharmaceutical factory's data terminal, I might be able to find out this person's information!"

Unexpectedly, Zeng Ke just finished speaking, but someone pushed open the door of the office again. But when Ran Tao was anxious, he ran in from outside and said breathlessly:

"Team leader, I think... I have found the real murderer!" Ran Tao swallowed and said impatiently, "This man is Liu Yu, the director of the R&D department fired by the pharmaceutical factory! This rapid murder case is likely to be his revenge!"

ah!?
