At half past four in the morning, the office of the Jinping Police Station.

Zhao Yu didn't break his promise, and really brought Cui Lizhu here, when Cui Lizhu saw Zhao Yu enter the police station all the way unimpeded, she suddenly wilted!

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

Although Cui Lizhu was tied up with a rope, which looked particularly strange, none of these police officers dared to ask carefully.

It wasn't until Zhao Yu took her into the office that a handsome young man finally asked, "Team leader, ...... are you?"

"Don't talk about this yet," after entering the office, Zhao Yu asked Cui Lizhu to sit on a chair next to her, and then quickly came to Zeng Ke and asked, "What's wrong?"

"Oh......" Zeng Ke hurriedly turned on his computer and said to Zhao Yu, "Team leader, I have checked the third deceased in detail, ......" He pointed the computer screen at Zhao Yu, "The deceased's name is Zhang Kaibin, and he is the deputy director of the quality inspection department of Changxin Longtai Pharmaceutical Factory, and he has just been brought up not long ago."

"This night, I almost found out all eight generations of his ancestors," Zeng Ke said excitedly, "This person's interpersonal relationship is good, not to mention in the pharmaceutical factory, even in life, and basically there has been no conflict with people."

"However, when I carefully investigated his resume, I suddenly realized that something was wrong!"

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

"Hmm......" Zhao Yu looked at Zeng Ke strangely, not knowing why he took out the transcript.

"Team leader, look at his resume again," Zeng Ke said excitedly, "He was transferred from the R&D department before he became the deputy director of quality inspection. Because of the development of a best-selling new drug, chloramitopine, he was promoted and raised!

"However, I checked his records in the R&D department, he has always been unknown in the R&D department, and with his scummy grades when he was in school, let alone the development of new drugs, he is not even qualified to stay in this team!"

"Wow! Chloramitoppine? I've heard of it!" Who knows, hearing this, Cui Lizhu next to her suddenly came to her senses, "This is a psychotropic drug with the least side effects at present! It's more than 500 yuan a box! It's much more expensive than butyrylbenzene!"

"Shut up, if you don't speak, no one will know that you are a psychopath!" Zhao Yu blackened her.

"Ahh

"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 is very marketable, once it is successfully developed, the orders are full, even abroad!" Zeng Ke said quickly, "This time Changxin Longtai can be listed abroad, and this new drug is also one of their projects!"

"Team leader, what's wrong is that the research and development of this kind of new psychotropic drug is generally a very long process, at least more than 8 years!" Zeng Ke pointed to the victim's photo, "But this Zhang Kaibin has not even been working for 5 years! Although it is only a name, the development of new drugs is not comparable to academic papers, and this is a major event that can leave a name in history, so I think ...... There's got to be a trick in there!"

"Oh?" Zhao Yu said after thinking about it seriously, "What do you mean, did someone poison Zhang Kaibin because he was not satisfied that Zhang Kaibin's name was written on the list of new drug research and development?"

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

"Huh?" Zhao Yu was suddenly shocked, Lu Xiaohong and Peng Ankang were the second and first victims of this rapid murder case. "So...... The killer is ...... according to this list"

Boom......

As soon as Zhao Yugang said this, the door of the office was suddenly pushed open, but he saw Wu Xiumin running in from the outside in a hurry:

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

Suddenly, Wu Xiumin saw Cui Lizhu with a confused face, she was stunned there, and while looking directly at Cui Lizhu, she asked, "Is this......?" What's the situation? Is this a murderer?"

"No, I'll explain to you later, hurry up, what did you find?" Zhao Yu hurriedly asked.

"I ...... Oh......" Wu Xiumin remembered the matter and hurriedly said, "I'm going to investigate the second deceased, Lu Xiaohong, she is a senior chemist in the R&D department of the pharmaceutical factory, this woman has just been working in the pharmaceutical factory for less than a year, and she was promoted to senior chemist, which seems a little unusual!"

"So, I spent the whole day today looking into her relationships, and I searched almost all of her colleagues. As a result, I discovered a shocking secret!"

"Wouldn't it?" Zeng Ke was surprised, "Sister Wu, the police have already investigated them many times, if there is a big secret, they should have known it a long time ago, right?"

"Hehehe......" Wu Xiumin said proudly, "this is where our psychologists come into play! When I investigated, I found that among the deceased's colleagues, several people reacted abnormally. They were nervous, anxious, and afraid, and it seemed that they were worried about something other than Lu Xiaohong's death!

"So, I took care of them a little bit, and it turned out to be ...... Guess what I found?"

Wu Xiumin's sale of this immediately aroused everyone's curiosity, and even Cui Lizhu next to her craned her neck to listen.

"I used a secret technique to quietly hypnotize one of them!" Wu Xiumin said with a twinkle in his eyes, "During the hypnosis, although he spoke vaguely, he ...... I still hear something!"

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

Zhao Yu was not shocked, because Wu Xiumin's resume had already shown that she had a specialty in hypnosis.

"It's not a big deal!" Wu Xiumin said proudly, "Listen to him, what he is worried about should be related to some new drug developed by their R&D department." It seems like...... At that time, a certain doctor had always been in charge of the research and development of new drugs, but for some reason, when the new drug was about to pass the review, that person suddenly resigned!

"I suspect that the whole rapid murder case is likely to be related to this incident!" 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 before their death......s!"

"Doctor, new medicine?" Zhao Yu's eyes widened, feeling that he had found the key to solving the case.

"However, I investigated the records of the pharmaceutical company, but I don't know why," Wu Xiumin frowned and said, "I didn't find the information of the doctor who developed the new drug!"

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

Who knows, Zeng Ke just finished speaking, but the door of the office was pushed open again. But seeing the burning Ran Tao running in from outside, he panted and said:

"Team leader, I want to ...... I've found the real culprit!" Ran Tao swallowed his saliva and said impatiently, "This person's name is Liu Yu, and he is the director of the R&D department who was fired from the pharmaceutical company!

Yes!?

Everyone was so shocked that they stood up from their chairs, but Wu Xiumin hugged her arms and said with an unconvinced expression: "Ran Tao, no matter what, you are behind me, didn't you say that you want to follow my surname?"
