The police in Tang's world

Chapter 111 The Death of Professor An

It has been three months since Professor An's death, and only her direct apprentice is still in the experimental group. His son usually lives in the school while attending classes, but only visits this villa from time to time.

The place where Professor An died in a fire has become a ruin, and with the fire brigade fighting the fire and rescuing people, it doesn't make any sense to go to any place, let alone any items with investigation value.

To find out the death of Professor An, the difficulty lies in finding out what evidence is left that can help Yan Yu find the murderer.

Therefore, we can only start from the victim of Professor An. Why did Professor An bring himself to death?
It must be because of the hallucinogenic black tulips. The shelf life of flowers is actually very short. The batch cultivated by Professor An has long since disappeared in the fire. The existing black tulips were recently cultivated by the deceased Zhen Cheng.

The deceased, Zhen Cheng, was Professor An's direct disciple. He had mastered the cultivation technology of black tulips before he could use this as a bait to gather other people back to this villa.

The fact that black tulips are so attractive to them means that the person who killed Professor An did not get the cultivation technology of black tulips, otherwise, he would not have come today at all.

Yan Yu realized that he was just walking in circles in a dead end. After thinking so much, he still couldn't confirm who the murderer was.

Yan Yu decided to look for physical evidence first, maybe there will be new discoveries, so that he can get out of this dead end.

Yan Yu greeted the people in the hall, told them to be calm, and lied to them that Sun Gene said that he had made an important discovery and needed to go out with him by himself, then avoided the crowd and let the uncle's men enter the room. He left the villa, sent Sun Gene out, and told them to take care of this burden first.

The uncle's confidant has been with the uncle for a long time. Knowing that the man in front of him with a slap in the face is probably a fool after being tortured to extract a confession, naturally he will not talk too much.

Yan Yu went back to the villa again, and this time began to focus on searching for Wu Chemical's room. Senior intellectuals were also interesting. They were obviously husband and wife, but they couldn't live in a room after they came to work in the villa.

And there are some things in Wu Chemical, which are almost on the bright side.

In his luggage, there were several boxes of transparent medicine boxes, which seemed to be medicines specially prepared by the hospital, but there were no labels on them, nor any labeled bottles.

Yan Yu had no choice but to take out his mobile phone, first earn a sum of money for Kiko, and then opened WeChat to send a photo of the medicine: "Help me check, what kind of disease are these medicines for?"

With the money, Kiko was very efficient and quickly found the answer on the Internet: "It contains methadone and sedative drugs. It seems that he is in detoxification? It seems that there are already signs of mental illness due to drug use. The parties involved in the case?" Kiko seemed very interested in his current case and wanted to continue the chat.

Yan Yu's mind is full of the current case, and after the case is settled, he can go home early to rest, and he doesn't want to chat, so he just sent a sentence: "Thank you." The implication is also obvious, only talk about business, and refuse to chat.

"Take care of my business, I should thank you, let's talk back." As a human being, Kiko naturally understood Yan Yu's implication, and stopped asking questions after being polite.

Yan Yu replied: "Talk back." He put the screen of the mobile phone in his pocket.

Wu Chemical is recovering from drugs. As a doctor of chemistry, if she wants to take drugs, she is fully capable of making them herself. The technology of making drugs is not difficult, and this is Thailand and not China, so the control over drug raw materials is much weaker.

If Wu Chemical had taken the initiative to become addicted to drugs, he probably wouldn't have started his Ph.D.

In this way, it seems likely that she became addicted to drugs because of her long-term exposure to black tulips, so she had to take opioid detoxification drugs and tranquilizers to control drug addiction.

However, Professor An announced the termination of the project shortly after developing this black tulip, and when she passed away, the batch of black tulips she cultivated were directly destroyed by fire.

Where did the black tulip that attracted Wu Chemical come from?Again, if she could cultivate herself, she wouldn't be here today.

Therefore, the black tulips are the batch cultivated by Professor An. For the cultivation of this new type of plant, the number of samples will be accurate to the individual plant. It is impossible for Professor An to find that one of his experimental samples is missing but there is no response. Wu The only time that chemistry can get black tulips is when Professor An is unable to resist, then it can be determined that Wu Chemistry is the murderer who killed Professor An.

Although he had the answer in his heart, Yan Yu, who had no evidence, continued to rummage, and finally found a document with some cultivation techniques in a notebook. It seemed that it did not come from a formal channel. This thing became the physical evidence to convict him,

It seemed that everything had come to light, but in view of the conduct of these three people, Yan Yu was still worried about this last genius, and chose to go to his room before announcing the answer.

Sure enough, there was a surprise in it. Yan Yu found the email correspondence between him and Professor An in his laptop.

The person who extracted the toxin from the black tulip was not Professor An, but him. He helped Professor An find this impurity after Professor An promised him to share the cultivation technology.

After Professor An died, he originally thought that this technology had been lost, but when Zhen Cheng invited him, he knew that the technology had not been lost, so he came this time to discuss technology sharing with Zhen Cheng, the successor of the technology. After all, this is what Professor An promised.

In this way, he can obtain more raw materials through legal channels, and maybe he can extract new types of medicines from them to benefit mankind without taking any risks.

After knowing the basic properties of the toxin extracted from the black tulip, Yan Yu found the bottle of toxin in the room.

This thing is a white tasteless granule, which is insoluble in water and alcohol, so it is impossible to put it in the drink, otherwise, as long as the person who drinks it is not blind, it can be seen that something is wrong.

Moreover, the other three are the assistants of Professor An. Professor An has never told them that black tulips can extract hallucinogenic substances, and Sa Tiancai and Professor An are in a cooperative relationship, and the research results of the two are originally shared. He can get the cultivation technology of this thing through reasonable channels. He needs Professor An to be alive before he can get it through formal channels. Professor An is dead and the technology is lost. He is the most painful person because he still Counting on extracting a new type of anesthetic from black tulips?

So Professor An's death was entirely done by Wu Chemical, and this couple was really a good match. They both wanted to make a fortune for themselves, and they were like killers to their colleagues.
