Li Jingang said: "No, Dr. Du, doctors are really highly educated people, how can they do such a thing? They are not short of money. ”

Du Lin shook his head: "You don't know this, in fact, people who have engaged in scientific research know that their research is very expensive, and if there is no funding from some large enterprises or sponsors, their research will not be able to go on at a step."

All they can do is go around and carry out their research, and when the results are achieved, they get their name and the sponsors get the money. ”

"I have just carefully studied the characteristics of this new type of drug, and I feel that the original intention of the person who studies this drug is not to make a profit, but to help people get rid of drugs.

Because from the perspective of a normal person, in order to pursue high profits, drug traffickers should hope that drugs have higher addiction and shorter episode intervals, so that drug addicts not only cannot do without this drug, but also need to spend more and more money to buy drugs.

But you look at the tears of this demon, by adding baking soda, he makes the pleasure of taking drugs more soothing, and makes the pleasure last longer, which is toxicologically equivalent to reducing the addictiveness of the drug.

And after taking this drug, the next drug addiction will be extended, and Li Xian said just now that some of them will even take up to half a month, which is obviously unreasonable. ”

Luo Han said, "What does Dr. Nadu mean is that not only is he not making and selling drugs, but he is also helping people get rid of drugs?"

Durin nodded: "Although I can't believe it, but in fact it seems to be like this." Just now, Officer Luo said that Zhonghu City, including the surrounding cities and counties, and even the large and small drug dealers in other provinces, all wanted to kill the producer of this drug.

Supposedly, when such a popular new drug appears, shouldn't their first reaction be to cooperate? Why do they shout and kill as soon as they come up? Because they can better understand that what this new type of drug has brought to them is not only an impact on their market share, but also a complete cut off their financial resources. ”

Luo Han nodded and said to Du Lin, "No wonder Captain Li insists on keeping you, as a professional, you do have a more unique perspective than us policemen. ”

In the days that followed, the joint task force of the Anti-Narcotics Brigade and the Criminal Investigation Brigade turned the direction of searching for the source of the demon's tears to those high-end people with considerable knowledge of chemistry and medicine.

For example, chemistry teachers in schools, university professors and graduate students in related majors, and R&D personnel of related enterprises have become the key targets of investigation.

A few days later, the criminal police team suddenly received a report: a doctoral student in the Department of Biochemistry of Zhonghu University of Science and Technology was killed at home, and the informant was his girlfriend who lived with him.

Li Xian and others and Du Lin quickly came to the scene of the crime.

After a preliminary understanding, the name of the doctor who was killed was Zheng Yi, and the informant was Sun Qing, and the two were classmates in college and boyfriend and girlfriend.

And this Zheng Yi is one of the key targets of the preliminary task force.

After graduating from the bachelor's degree, Zheng Yi was admitted to the master's and doctoral studies in biochemistry at the university, while Sun Qing chose to work instead of taking the postgraduate examination, and the two lived a normal life.

But during the on-site investigation, drug supplies were found in Zheng Yi's home, as well as some demonic tears, and Sun Qing also admitted on the spot that he was a drug addict.

Zheng Yi's study was turned into a mess, his computer was destroyed, and his hard drive was removed.

Apparently the killer was trying to find something here, but it was not known if he had found it.

Shui Guochang did a simple autopsy at the scene, and Zheng Yi's cause of death was suffocation by a string.

Sitting in the interrogation room of the criminal police team, Li Xian and Qu Mingming looked at Sun Qing, who had been crying on the other side.

"Ms. Sun, please adjust your emotions, I will ask you straight to the point, 'Devil's Tears', is it prepared by Zheng Yi?"

Sun Qing nodded: "It's him, he made it for me." ”

Sun Qing wiped her tears, took a sip of water, and began to tell the whole thing in and out.

She and Zheng Yi are classmates in the same class, Sun Qing's talent in the major is not as good as Zheng Yi, so she chose to find a job, while Zheng Yi is studying for a graduate degree while doing scientific research.

Sun Qing began to work in drug sales, in order to get more orders and better performance, she had to accompany different people every day, drinking and eating, singing and dancing, all kinds of entertainment, and finally even became addicted to drugs under the bewitchment of customers.

Zheng Yi knew that everything his girlfriend did was for him, so he changed his scientific research direction and wanted to research an "antidote drug" that could cure drug addiction.

His previous research project was to study a drug therapy to treat the symptoms of allergy patients.

The method of gradually and slowly increasing the concentration of allergens makes the body of allergy sufferers gradually develop resistance to allergens, so as to achieve the effect of curing allergies.

In order to get his girlfriend to quit drugs, Zheng Yi reversed the previous research results. By gradually slowing down the stimulation of the brain and nervous system by drugs, the body's dependence on drugs is gradually reduced, the withdrawal reaction is minimized, and the goal of complete drug withdrawal is finally achieved.

But to study this project, it is necessary to get drugs. As a scientific researcher, Zheng Yi is of course reluctant to get drugs through illegal channels, and his girlfriend has a way, but the purity of the drugs he can get is not enough. So he found the company that had been funding his research all along, Wang's Pharmaceutical.

This is a well-known pharmaceutical company integrating drug R&D and drug production, with annual sales of more than one billion yuan, and nearly 100 million yuan of investment in drug R&D alone every year.

Wang's Pharmaceutical is very interested in Zheng Yi's project. So he not only funded Zheng Yi's research financially. Moreover, he used the formal channels of the pharmaceutical factory to obtain a lot of drugs, which was convenient for Zheng Yi to engage in research.

I have to say that Zheng Yi does have a very high level in drug research and development, and he quickly made several samples.

And his girlfriend Sun Qing became his assistant and experimental subject.

He would ask Sun Qing how she felt after each time she used its products and adjust the formula according to the changes in her physical condition.

Within half a year, he had prepared a drug for detoxification, which Zheng Yi named "Devil's Tears".

It means that the demon of drugs, after poisoning mankind for hundreds of years, finally shed tears of remorse, and this "devil's tears" is the medicine to quit drug addiction.

In accordance with the agreement with Wang's Pharmaceutical, he handed over the formulation of the drug to Wang's Pharmaceutical, and Wang's scientific team continued to complete further development and optimization.

Soon after, Sun Qing heard that demonic tears began to appear in the underground drug market in Zhonghu City, so she told Zheng Yi the news and brought back some demonic tears that she had bought in the drug market.

After analyzing the tears of these pirated demons, Zheng Yi was very angry.

Because according to the agreement, Wang's Pharmaceutical should deeply optimize and upgrade the devil's tears to further reduce its toxicity and addiction. However, when these pirated goods are mixed with baking soda, they enhance their toxicity and weaken the effect of drug rehabilitation, making them a new type of soft drug.

In particular, Zheng Yi heard that Wang's Pharmaceutical is still selling this new drug under the banner of "doctor".

Zheng Yi demanded that Wang's Pharmaceutical must immediately stop this kind of drug production and trafficking, otherwise he would surrender to the police and release the formula of the devil's tears to the whole society.

Zheng Yi is just a scientific researcher, and he doesn't understand how tempting profit is for capitalists.

So he died.
