Got it! Zeng Mishan's eyes lit up, and he actually found a piece of information from his memory bank.

Nagai is actually a person's name. He used a method when studying the structure of ephedrine, and the synthesis method was named after him.

Zeng Mishan nodded, then said calmly, "The Nagai method involves the reaction of ephedrine or pseudoephedrine with iodine and red phosphorus to produce methamphetamine."

Methamphetamine is ice.

Upon hearing this, Pete, who was reaching out to touch the vessel, felt a slight tremor in his palm.

He turned and looked at Zeng Mishan, his eyes burning with passion, and said, “Yes, you can now observe my refining process.”

After saying that, Peter gave Aaliyah a look that only his own people could understand.

What I mean is that the helper you introduced is pretty good and not a fake who knows nothing.

"Very good, let's get started!" After that, Alia picked up the walkie-talkie and said, "You can come in."

As the laboratory door slowly opened, the jailer walked in pushing a flatbed cart loaded with goods.

After putting down the flatbed, Alia and the jailer tactfully walked out.

The poison refining process might produce highly toxic substances, which was why she didn't want to stay here and consume the poison.

Could Commons really get the controlled materials? Zeng Mishan looked at the flatbed truck with suspicion, but he miscalculated...

Are these matches? After unloading the cargo from the flatbed truck, Zeng Mishan was stunned by the boxes of matches.

Shit! So that's what happened. Zeng Mishan slapped his forehead. Red phosphorus is a controlled substance and cannot be purchased, but matches are not.

Match heads are red phosphorus, which can be purchased in large quantities on Taobao. You just need to scrape off the red phosphorus from the match heads.

Is this cold medicine?

Opening another box, Zeng Mishan found a large number of daily cold medicines, including Xin Kangtai, Baijiahei, Phenomenal Meprobamate tablets, and Ibuprofen and Pseudoephedrine Dispersible Tablets.

He grabbed the cold medicine and looked at the ingredients, and was attracted by the pseudoephedrine in it.

Ephedrine is the main raw material for making methamphetamine. Its production, use, sale, import and export are strictly controlled in all countries.

But cold medicine is not restricted. Zeng Mishan touched his forehead and felt that he was getting closer and closer to the truth.

“It’s iodine.”

Iodine is a daily necessity and there is no purchase restriction.

So that’s it! So that’s it!

Zeng Mishan suddenly realized and lamented that the so-called methamphetamine was actually made in such a crude and crude way.

It's really like a mountain between two different fields. There is only a thin layer of paper between me and the truth, which can be broken with a single poke.

After putting on the protective suit, Zeng Mishan felt a long-lost sense of familiarity come over his whole body.

Now that he had figured out the raw materials, the rest was no difficulty for him.

"You'll be responsible for scraping off the match heads, and I'll be responsible for grinding the cold medicine into a fine powder."

Pete gave Zeng Mishan an instruction.

Half an hour later, the two completed the tedious first step.

The next step is to pour the finely powdered cold medicine into the solvent to dissolve it.

Zeng Mishan took the initiative to hand over the industrial alcohol.

Because he knew that pseudoephedrine was soluble in ethanol and ether.

Ether was too expensive, so he only found ethanol on the scene.

Looking at Zeng Mishan with some surprise, Pete suddenly felt that having a partner was indeed convenient.

"Let me help you filter it!"

Zeng Mishan reacted quickly. He took out filter paper to filter the solution to remove impurities.

This is also the simplest way to extract pseudoephedrine from cold medicine.

"Hmm!" A good partner only needs to work together once to know whether it is going well.

Pete was very satisfied with the middle-aged man in front of him. He could predict his steps, which was very good. It could help him save a lot of time.

The next step is to take out a certain amount of red phosphorus and iodine.

Iodine should be stored in a brown bottle because it sublimes easily and should be kept in a dark place.

Listening to Zeng Mishan's mumbling, Pete curled his lips and admired Zeng even more.

The next step is to pour the three raw materials into a large flask, and finally add iodine, which will produce a violent reaction.

"Wait!" Zeng Mishan suddenly shouted.

He found a way to react that was so hilariously wrong that he couldn't stand it any longer.

"Mr. Pete, isn't your condenser connected to the water pipe?" Zeng Mishan was an extremely rigorous person who would not tolerate any errors in his eyes.

The function of the condenser is to use water to lower the temperature and liquefy the gas for easy collection.

If it is refined according to Pete's method, the final purity will be greatly reduced, which is also the most disgusting scene for a hardcore chemist.

Pete chuckled and offered his workbench, implying: Are you trying to teach me how to do things? Come on, come on, if you can do it, do it!

Zeng Mishan was not polite either. If this was his student, scolding him would be a small matter. He might even reward the other person with a big slap in the face.

After Zeng Mishan solved the problem of the condenser, he suddenly panicked:

"Damn it, why is there no constant temperature water bath?" Zeng Mishan was furious. At the critical moment of refining, there was no suitable equipment. Isn't that infuriating?

The function of the constant temperature water bath is automatic temperature control, easy to use and precise temperature control.

"Hurry, go find a rice cooker." Zeng Mishan suddenly urged, he wanted to try everything.

When it comes to chemistry, Zeng Mishan is a person who is meticulous to the point of decimals, and temperature often determines victory or defeat.

Taking the walkie-talkie from the material rack, Pete conveyed his needs to Alia.

In less than five minutes, there was a knock on the door, and a prison guard wearing a gas mask pushed in a flatbed cart with four or five rice cookers on it.

"Let's give it a try!" Zeng Mishan rushed over, turned on the rice cooker and placed it under the flask.

This step of temperature control is crucial and is the finishing touch in methamphetamine production.
