When Li Quan picked up the seventeenth cigarette butt and put it on his nose to smell it, his eyes lit up slightly.

Found it, it should be this cigarette butt.

The smells emitted by other cigarette butts are similar, mainly sponge filters and tobacco leaves. Some of them also have the bad breath smell that others leave on them after drying.

Most people who smoke will have bad breath.

This is the gas after the cigarette burns and reacts with saliva in the mouth, and then attaches to the teeth, tongue, oral wall, etc. It is difficult to clean up.

This odor of smoke is generally acceptable.

There is also a odor that has nothing to do with smoking, it is purely oral odor. Most people like to brush their teeth or have caries.

After eating food, especially meat food residues, trapped into rotten caries, and then because there are a lot of bacteria in the mouth and the humid environment, the temperature is as high as the body temperature of the human body.

This warm and humid bacteria-free environment can easily accelerate the corruption of food residues.

In the end, the mouth of such people will emit a bad smell like rotten eggs, dead fish, and their saliva is also smelly.

When the saliva remains in the cigarette butt, the odor will remain for a long time.

Every time Li Quan smells that kind of cigarette butt, it feels as disgusting as eating a dead fly.

Therefore, we must take care of our teeth and develop the good habit of brushing our teeth every morning and evening.

Many people think that there is no need to brush their teeth at night. In fact, brushing their teeth at night is more important than brushing their teeth in the morning.

"Did the young man find a problem with this cigarette butt?" asked the old detective.

"Smell it and see how it is different from the cigarette butts of ordinary cigarettes." Li Quan put the cigarette butt in front of the old detective's nose with the cigarette butt.

The old detective's nose twitched, carefully distinguishing the smell emitted by the cigarette butt.

"Its tobacco smell is very light, and it seems to have a Chinese medicine smell. In addition, its cigarette holder does not look like it has been sucked. If it has been sucked normally, its saliva will be soaked into the wrapping of the paper and the sponge of the filter."

He is worthy of being a professional criminal policeman, and his recognition ability is far beyond that of ordinary people.

Observe meticulously.

Li Quan put the cigarette butt back into a separate plastic bag.

It has basically burned out and burned to the sponge filter. If it has not burned out, you can directly find out what medicine is filled with it.

Now we can only distinguish based on the residual Chinese medicine smell on it.

Li Quan was preparing to take it back and carefully distinguish the smell of the cigarette butt by identifying medicine in a closed environment without any interference.

Although he had basically confirmed that the cigarette butt was looking for, Li Quan still took a cautious attitude and identified all the remaining seven cigarette butts.

The last one was so smelly that he had a dry retard.

The saliva on this cigarette butt was not dry and it smelled particularly bad.

It's the smell like a dead fish.

"It seems that it's just that cigarette butt. No other cigarette butts I need."

Li Quan took out the cigarette butt that emitted the smell of Chinese medicine alone.

"I want to take this cigarette butt back to the hospital first to identify the medicinal ingredients it contains. Is it OK?" Li Quan asked.

"I'm afraid it won't work!" the old detective refused. "If this cigarette butt is really left by the suspect, then there is probably a suspect's fingerprint or even DNA information on it. We police cannot hand it over to you such an important evidence."

Officer Han next to him did not speak.

The key evidence cannot be taken away by Li Quan.

Friendship is friendship, and the law should be fair and strict, and must be abided by it.

"Or why not do this. If President Li really needs it, he can go back to the police station to study this cigarette butt with me." Police Officer Han is the highest-ranking person here. After he spoke, no one dared to refute it.

In front of outsiders, he and Li Quan still maintain the title of public office.

Everyone understands this.

Some relationships are better if they are not announced.

Once it is made public, it can easily cause public misunderstandings and will also cause many unnecessary troubles.

"Well, that's OK."

Anyway, Li Quan just needs to find a closed environment without odor and carefully distinguish what drugs have the cigarette butt been filled with before?

...

In a room in the police station, Li Quan sniffed the cigarette butt with a sniff.

It has the smell of Astragalus, which is relatively strong.

There is also the smell of realgar.

These two things have no hallucinogenic effects. There must be the most important drug ingredients that have not been discovered.

Li Quan continued to tackle the problem.

There is a very light herb smell, a bit like the smell of mushrooms, which is relatively light.

There are some poisonous mushrooms in the mushrooms, which do have hallucinogenic effects.

But I have never heard of any kind of mushroom that can make people poisoned by burning.

Generally, it needs to be consumed before it will get poisoned.

What kind of medicinal herbs are it?

After careful identification, it is still somewhat different from the smell of mushrooms.

Li Quan closed his eyes and thought carefully, and many of the magic medicine-distinguishing experiences accumulated by the miracle doctor Li Shizhen were found in his mind.

Nothing gains.

It seems that even Li Shizhen has never seen this herb.

After Li Quan learned more miraculous medical skills, he learned a new way of using them. That is, two types, or even more miraculous medical skills combined.

It's a bit similar to the combination punches in fighting.

If two or more different boxing methods are combined together, its lethality is often several times higher.

There is no such odor in Li Shizhen's medical experience, so what about other miracle doctors such as Shen Kuo and Bian Que?

At this moment, Li Quan's brain is like a scanning machine, and the medical experience and diagnosis and treatment experience of miraculous doctors are all ready.

First, we scan Shen Kuo’s medical experience.

Because Shen Kuo is very good at pharmacology, medicinal properties, etc.

In terms of identifying medicines and identifying medicines, I believe that I have accumulated knowledge far beyond other miraculous doctors.

It’s just a pity that I didn’t find what I wanted in Shen Kuo’s medical experience.

Li Quan was not discouraged, but a miracle doctor and a miracle doctor's investigation.

I believe that so many miraculous doctors will always gain something.

When he found Wu Zixu's medical experience in treating tomb diseases, he was surprised to find that the smell of a drug is highly similar to the smell that is smelled in cigarette butts.

That's right, it's this medicine.

The name of this medicine is corpse ginseng and only appears in the tomb.

The seeds of each cinnabar are a corpse.

Moreover, it takes extremely harsh conditions to make the corpse grow ginseng.

This is recorded in Wu Zixu's medical experience.

Corpse ginseng grows on or in tombs, in dark and smelly places. Dead corpses are used as seeds, and if no one destroys them, they can survive for more than a hundred years. Corpse ginseng is poisonous and has a hypnotic and anesthetic effect. It is said that this medicine can bring about life and resurrection.

Unfortunately, Li Quan has not yet learned Bian Que's resurrection technique.

Otherwise, there may be mentions corpse ginseng.

"It is now certain that Sophie's poison is corpse ginseng."

As for why the criminals added two medicines, astragalus and realgar to the cigarette, this is not a problem for Li Quan.

The functions of Astragalus in the pharmacopoeia are introduced as follows: replenish qi and strengthen the exterior, support toxins and discharge pus, diuresis, and muscle growth. It is used for qi deficiency and fatigue, long-term diarrhea and prolapse of the anus, spontaneous sweating, edema, uterine prolapse, chronic nephritis proteinuria, diabetes, and sores that do not heal for a long time.

It can cure many diseases.

It specifically mentions replenishing qi and strengthening the exterior, and supporting poison to discharge pus.

This kind of thing is probably added to reduce the harm caused by corpses to the human body, so as not to cause death or serious injury or disability.

Another drug, realgar, its main ingredient is sulfide minerals, which mainly contain diarrhea disulfide.

Realgar is warm and dry, and can fight against poison and treat sores. It is a drug for treating sores and anti-virus. It is suitable for carbuncles, furuncles, snake and insect bites, and scabies. It has the effect of insecticides.

In fact, many people don’t know that realgar has a catalytic effect after being burned.

It can catalyze any drug, including alcohol, poison, curing drugs, etc.

The gangster is definitely a master of medicine dispensing.
