Cheng Chubi stayed in the room dedicated to various chemical tests. No one was allowed to enter or leave here.

For example, he is currently producing sulfuric acid and nitric acid. The danger of this thing is absolutely life-threatening.

Saltpeter has already begun to be sold in this era, and the main buyers are generally Taoist priests. The most popular thing for those guys is to catch and refine.

Cheng Chubi thought he couldn't afford it, so he still honestly followed the laboratory procedures to prepare it.

Looking at the glassware and utensils cut and polished with crystals in his own room satisfactorily, this made Cheng Chubi feel very much.

If there is no glass, he would not dare to do this, after all, things like nitric acid and sulfuric acid are really dangerous.

Although ceramics and other utensils are also corrosion-resistant, they are opaque, making it impossible to visually see if there are any abnormalities inside.

Wearing a mask, Cheng Chubi began to light the alcohol lamp made of the essence of the wine, and then began to dry the saltpeter...

Outside the house, Cheng Fa and Cheng Da continued to practice small animals for dissection and appendectomy and other minor operations.

Another more important task is to help Cheng Chubi look outside the house and strictly prohibit anyone from going inside.

Cheng Chubi sat peacefully in the room, repeatedly watching the steps of extracting nitric acid and sulfuric acid written in his prescription.

While observing the change of the saltpeter, it gradually passed by bit by bit over time.

What Cheng Chubi didn't know was that he had already crooked the technological tree of Datang's chemical industry to the sky.

After spending almost half a day of work, Cheng Chubi placed two dark glass bottles in front of him, one green and one red.

The green bottle is pasted with green paper, and it is written in the regular font: sulfuric acid. After all, this thing is made with green alum, so it is easier to distinguish it with a green bottle.

The red bottle is naturally nitric acid. Cheng Chubi thought about it, and decided not to die before preparing a more corrosive aqua regia, because it didn't make much sense to make it out.

He is just a doctor, not Te Niang's biochemical madness. As a medical student, Cheng Chubi has a strong thirst for knowledge, but there is absolutely no thirst for death.

The preparation of nitroglycerin tablets is actually very simple. The nitroglycerin is dissolved in alcohol in proportion, and then mixed with a sufficient proportion of starch syrup and syrup.

This is the complete production process of nitroglycerin tablets. It is simple and simple, but it is too troublesome.

After all, in order to standardize, it must be the same as the production of compound Danshen tablets, starting with 1,000 tablets.

I thought of doing so much dangerous medical and pharmaceutical work for Chai Shao.

Cheng Chubi felt that the cost of the medicine would have to be collected at least ten dollars, otherwise it would be too uneconomical.

As for nitric acid and sulfuric acid, he hid these two extremely dangerous liquids in a place where no one except himself could find them.

After finishing all this, Cheng Chubi came to the house, only to realize that the sky was getting faint.

Forget it, I will go there by myself tomorrow to deliver medicine to General Chai.

#####

"That's it? Just ten?" Chai Shao asked in a daze, looking at the finger-sized porcelain bottle that Cheng Chubi handed over.

Cheng Chubi looked serious and authentic.

"Yes, ten pills in a bottle, and if you have opened the bottle, uncle, the shelf life of the remaining medicine is only three months."

"After three months, even if it is not used, it has no effect."

"You only need to take a bottle with you. As long as you feel that you are about to get sick, Uncle Chai, remember to open the cork as soon as possible.

Take one pill under your tongue, not swallow it, but hold it under your tongue, so that it can take effect in the shortest possible time and save your life. "

Seeing Cheng Chubi's serious expression, Chai Shao didn't dare not take it in his heart, so he could only carefully write down Cheng Chubi's words.

"Okay, don't worry, the old man can definitely engrave your instructions and make no mistakes."

Cheng Chubi took out three more vials and handed them over.

"As for the other three bottles, please also ask Uncle Chai to store them in your ice kiln to reduce the volatilization of the medicine."

"But even so, wait until this time next year, remember to send someone to remind my nephew, and then prepare the medicine for you."

"Okay, this is okay, this is the life of the old man, I will definitely remember it."

But before it was over, Cheng Chubi took out four small bottles like a conjure, and handed them to Chai Zhewei and Chai Lingwu who gathered in Uncle Chai's study.

"Brother Zhewei, and Brother Lingwu, you two brothers are also one person and one bottle. You must also remember to remind Uncle Chai to carry medicine with you.

Even more, I want to tell everyone in your house that once Uncle Chai gets sick, if he can't get the medicine, then you have to help him..."

"These two bottles are best to be handed over to uncle Chai's personal companions, so that he can take medicine for Uncle Chai in a critical moment."

"Nephew, don't need to..." Chai Shao couldn't laugh or cry.

This Cheng's youngest man was serious, talking and taking out a small bottle, which was really speechless.

"Now my nephew, I am a healer, and this is responsible for the patient's life. This angina pectoris attacked and survived without death. This is a very small chance..."

"It is impossible to have such good luck forever."

Cheng Chubi looked at this general Chai, who was a little unsure of what's good or bad.

On the contrary, Chai Zhewei and Chai Lingwu were more attentive than General Chai, and they remembered Cheng Chubi's words firmly.

"Don't worry, brother Chubi, my father can't remember, and my brother and I can definitely remember."

Chai Shao opened his mouth, but seeing the expressions of his two dolls so serious that he could no longer be serious, and thinking of his wife's early death, if he had anything to do with him.

Finally sighed lightly. "Okay, let's just listen to Chu Bixian's head office, right?"

"That's right, come on, Uncle Chai, let's discuss the same medical expenses." Cheng Chubi smiled and leaned forward.

"???" Chai Shao was a little bit dumbfounded and looked at the youngest Cheng who sat in front of him and started rubbing his fingers.

Chai Zhewei and Chai Lingwu on the side also have black lines on their faces. Sure enough... I've heard that the old Cheng's family is cheeky, and the old ones are fine, and the little ones are thicker.

"I said, Brother Chubi, are you like this?" Chai Zhewei couldn't help laughing.

Cheng Chubi was directly unhappy. "Your Majesty bought my goat's milk soap all the time, and your father received my medicine, can you still not pay for it?"

These words caused the three of the old Chai family to roll their eyes, crying and laughing to look at the face of the old Cheng family.

Cheng Chubi sighed long. "Two Brother Chai, Uncle Chai, you don't know, it's not that my nephew is thick-skinned, it's really that this medicine is too rare to make.

Moreover, it is very harmful, and my nephew can be regarded as this kind of glycerin heart-saving pill made by fighting hard. "

"Yes, how much do you say? The old man doubled it for you." Chai Shao chuckled, then winked at Chai Zhewei.

Chai Zhewei happily ~www.NovelMTL.com~ and slipped out lightly.

"Uncle you said so, I am embarrassed. Let's do it, six rounds of six hundred and sixty dollars, six or six good luck."

"Uncle you give too much to me and I don't want it, just this number."

"Yes, I'll give it to you after I have dinner."

"eat?"

"Hey hey, the old man let your kid go a few times in a row. Now that you have brought all the medicine today, do you think you can go straight out?

The eldest and second child, father does not drink when he is sick. Your brothers will entertain the old man's lifesaver for me. "

"No! Hahaha, Cheng Lao San, let's go..."
