After sending away Jiang Ziwen, the king of Qin Guang, Du Lin used the secret method he had just learned to make Gu Amei the new master of Shi Yunwen.

Although Gu Amei has been in the society for many years, she is only a young girl who has just 20 years old after all, she likes new and exciting, and she says that she doesn't want to be Shi Yunwen's master, but after she really accepts Shi Yunwen, she is reluctant to take Shi Yunwen back into her body, and she can't wait for the world to see that he has a ghost as his bodyguard.

He and Du Lin were ghosts, and when they met Professor Wang, it was already the middle of the night.

Professor Wang found someone to send the female student back to the affiliated hospital, planning to observe for another day or two, and then she could be discharged without any problems.

Professor Wang invited Du Lin and the others to have a supper at a 24-hour porridge shop, and then dispersed.

People are forgetful.

A few days have passed, and the turmoil of this incident has subsided, and there is no longer any news of the supernatural incident in the medical university on Weibo, instead of "someone in Zhonghu City died violently on the street, bleeding from the seven orifices, and the death was terrifying".

Li Xian rarely had a few days to spare, and he had accompanied Mo Anran to deal with the supernatural incident at Zhonghu Medical University before, but he had started to get busy again in the past few days.

The reason is the mysterious death of the few people on the street mentioned on Weibo.

After Shui Guochang's autopsy and the identity background check of the deceased, the four mysterious deceased found either had a recent history of drug abuse or were registered drug users.

So Li Xian suspects that the deaths of these people are all due to drug overdoses.

However, in general, drug overdose deaths occur during drug abuse or shortly after drug use.

It is indeed very rare to die on the street like this.

And the current situation is that there have been many deaths in a short period of time from drug overdoses, which is even more incredible, and it has also caused a bad social impact.

Li Xian sent the blood samples of these deceased to the hemolysis clinic, and asked Du Lin to help find out what drugs these people were taking, and why did they die so miserably?

Durin specifically asked the deceased about the time of death, and determined that a blood sample that had not been dead for more than 24 hours was marked separately.

After Li Xian left, Du took the blood sample into the testing room, and drank the blood sample that had just been marked directly into his stomach, although it was the deceased who had died recently, but nearly twenty hours had passed, so the hallucinations that appeared after drinking the blood were few and very broken, but Du Lin still saw a lot of important information.

Before his death, the deceased had mixed two powdered objects, one purple and one white, dissolved in normal saline, and inhaled into a needle for injection.

After the injection, I had hallucinations, and the illusions became whimsical and bizarre, sometimes as if I was flying in the sky, and sometimes I felt that everything around me was very slow......

Due to the length of his death, Dühring was unable to discern from the visions what these two powdery objects were, nor where they were obtained.

There were four blood samples sent by Li Xian, each belonging to the four deceased, and Du Lin examined these blood samples twice with his own tongue and instrument.

The blood samples of all four men all had one thing in common: they had all used some kind of drug shortly before they died.

And the reason for their death is precisely because after taking this drug, the brain has a strong hallucination, which leads to the death of too intense cranial nerve activity, to put it bluntly, it is excited to die.

In fact, the content found by Du Lin has also been discovered by Li Xian during the investigation.

The police found two kinds of powders in the deceased's residence, one of which was a new type of drug called "devil's tears", and the other white powder was "sodium thiosulfate", commonly known as "baking soda".

Although Li Xian has never been an anti-narcotics policeman, he has been exposed to the police force over the years, and he also knows the tricks of some drug dealers and drug addicts.

In order to pursue profits, some drug dealers will add some painkillers, starch and other excipients to the purity drugs, and some even add rat poison and lime.

And some addicts, in order to use the least amount of money to live a more addictive life, know that the drugs they buy have been diluted by messy things, and they have to mix glucose and other relatively easily available excipients again to further dilute them.

However, this is indeed the first time I have heard of baking soda like this.

At this time, Du Lin's network once again played a role, and Du Lin sent the "devil's tears" and sodium thiosulfate found by the police to the desk of Dean Fang Xiaoru of the Clinical School of Zhonghu Medical University.

The dean of the entrusting party used the resources of Zhonghu Medical University to help the police analyze what kind of special effects the demon's tears and sodium thiosulfate would produce when mixed.

Since the last dispute between Chinese and Western medicine, Dean Fang admired Du Lin very much, so he was very happy to help Du Lin with this favor, personally contacted a professor who specializes in chemical drug toxicology, and gave the analysis results to Du Lin two days later.

According to the analysis of experts, this so-called "devil's tears" is essentially the same as other new drugs, which are nothing more than new varieties of several different drugs mixed according to different proportions.

But once sodium thiosulfate, or baking soda, is added to the drug, its effects become both violent and long-lasting.

Through animal clinical trials, it was found that different doses of baking soda were mixed with the same dose of devil's tears and injected into different mice.

The mice began to ram the cage frantically, trying to get out of the cage.

When the experimenters released the mice on the premise of ensuring safety, the mice began to spin wildly in the open space.

In the end, he died in the middle of the experimental site, which is very similar to the state of the addicts who died violently on the street on Weibo.

Because these cases involved drugs, the anti-drug brigade of the Zhonghu City Public Security Bureau sent two experienced anti-narcotics policemen to solve the cases together with the criminal police team.

One of these two anti-narcotics policemen is called Luohan and the other is called Li Jingang, I don't know if it is fate or coincidence, the two of them together happen to be "King Kong Arhat".

On this day, Li Xian invited King Kong Arhat and Du Lin to the criminal police team to analyze the case together.

After reading the toxicological analysis report issued by the experts brought by Du Lin, Luo Han said: "The drugs consumed by these deceased people are related to a drug trafficking case that we are investigating during this time. However, when we investigated the case, we found that the drug distributors, commonly known as 'house breakers', would sell the new drug to addicts by telling them to dilute it with baking soda and devil's tears before injecting it. ”

"Baking soda is sodium bicarbonate, and as far as we know, when the devil's tears are mixed with baking soda, the user will experience a gentle and long-lasting pleasure, which is also the characteristic of this new type of drug.

But it is clear that the dead were mistaken, replacing baking soda with baking soda. Judging from the expert's report, although baking soda and baking soda are only one word apart, the chemical composition is sodium thiosulfate and sodium bicarbonate, which can be described as a world of difference.
