Chapter 777 Can I eat it?
"Pei Qing, please sit down. Please sit down."

This was the first time Cao Mao summoned Pei Xiu to the West Hall. In the past, there were very few ministers who could be summoned to the West Hall. Apart from those members of the royal family, there were only a few confidants.

The rest of the people were basically formally received in the East Hall.

This was the first time Pei Xiu was summoned alone to the West Hall.

This shows that Pei Xiu was truly accepted by Cao Mao and became one of Cao Mao's true confidants.

When Cao Mao held Pei Xiu's hand before, Pei Xiu didn't feel anything, but this time he felt a little excited.

I never thought that I could conspire with His Majesty alone in the West Hall!
In the past, Zhong Hui would sit here and conspire with the emperor on how to make him suffer!
Pei Xiu felt a little secretly happy when he thought that he could conspire with the emperor to make others suffer in the future.

Cao Mao asked directly, "I'm looking for you this time because of something you're very good at."

"Oh? Your Majesty, are you planning to draw a map?"

Pei Xiu asked hurriedly.

"No, it's about the refining and dispersion."

Cao Mao looked sincere, but Pei Xiu was surprised.

Your Majesty, please stop testing me.

I really can’t accept it!!

Pei Xiu explained helplessly, "Ever since Your Majesty informed me of the dangers of taking powder, I have never touched the Cold Food Festival medicine again. It has been many years. As for refining powder and elixir, I have completely forgotten about it."

Cao Mao shook his head and said, "Don't be afraid. I don't mean to scold you. I just want to ask you something."

"Do you know green vitriol?"

When Cao Mao asked this, Pei Xiu immediately replied, "I know. Take four parts of alum and six parts of soybeans, add two liters of water and boil until it becomes one liter. Add half a cup of honey. Why do you ask this, Your Majesty?"

Cao Mao looked at Pei Xiu dimly.

He had always thought that Pei Xiu would only live to his forties because of his strong appetite.

Now he thought, how could he have lived to be over forty years old by taking such medicine?

Don't stuff everything into your mouth!
They are all biochemical demons from the Wei and Jin dynasties, right?
Seeing Cao Mao's look, Pei Xiu said seriously, "I have been unwilling to leave for a long time."

"Xiu, this thing is poisonous, you..."

Cao Mao didn't know what to say.

The main ingredients of Wu Shi San are composed of five kinds of stones, namely cinnabar, realgar, alum, azurite and cinnabar.

In fact, this is extracting the chemicals.

But understand, there is not just one recipe!
The Wei and Jin Dynasties were a time when people were crazy about refining and eating stones. Ever since He Yan, a famous scholar in the world, set a precedent for people to become famous by taking powder, countless people followed his lead.

From the royal family to the clans, and down to the scholars at the bottom, everyone regarded wearing mourning clothes as an elegant thing and was crazy about it.

They began to painstakingly study various recipes. There was nothing they dared not eat. At that time, there were dozens of main recipes circulating among the people, not to mention those folk remedies. More than a hundred of them were considered a small number.

These recipes continued to appear many years later, and Sun Simiao recorded many types. In the end, he simply warned everyone: If you come across a recipe of this type, burn it and don't keep it to harm the world!
And these things are all primitive chemical equations. God knows what they have actually produced.

Then the world entered an era of complete madness.

Although we cannot blame everything that happened at that time on the medicine, this thing really caused endless harm.

Cao Mao asked again: "What about the phosphorus stone?"

Pei Xiu asked suspiciously, "Can phosphorus stone be eaten?"

"Well, I found some ancient books and learned about the method of making fertilizer."

Contrary to what many people think, the Chinese people realized very early that weeds in the fields can promote the growth of millet after they rot, probably as early as the Western Zhou Dynasty.

In the "Fan Shengzhi Book" of the Han Dynasty, there is a detailed record of knowledge on how to apply fertilizer to the land.

During the Wei and Jin Dynasties, fertilization technology was already very advanced, and further advancement came after the promotion of rice in the Song Dynasty.

At this time, people knew how to use human and animal feces, rotten weeds and other materials as fertilizer.

However, the effect of this folk remedy is always limited and is obviously not enough compared to chemical fertilizers.

If it were in other dynasties, it would probably be very difficult to produce these. Although this type of fertilizer is not difficult to make, it still requires professionals.

This problem did not exist in the Wei and Jin dynasties because there were simply too many professionals.

Just like Pei Xiu, when Cao Mao asked him about the origin of these minerals, he could not only tell where these things could be found, he could even describe what these things tasted like!
Pei Xiu was also very surprised at this moment.

He knew that different formulas of powder would have different effects. For example, the alum His Majesty had just mentioned, when combined with different ingredients, could cause fever, chills, or even ascension.
But he really didn't know that these things could be used as fertilizers.

During the Han Dynasty, people were very sensitive to things like alchemy. Especially the emperor, if he dared to ask his ministers about related matters, it would probably cause a lot of people to threaten his own death. They would directly use the example of the First Emperor, saying that they would die in front of him and demanding the execution of the ministers who spoke to him.

But nowadays, everyone is very accepting of it. Taking powder is an elegant thing, and so is refining pills. What is there to object to?

The two began to chat about various kinds of stones. As expected, Pei Xiu was very knowledgeable about stones. There were many stones that Cao Mao didn't know what to call them. As long as Cao Mao could describe them roughly, Pei Xiu could immediately tell them the name.

He is indeed a ruthless man who died from taking medicine!

But when Cao Mao talked to him about production, Pei Xiu hesitated.

"Your Majesty, although I used to take the powder, I am not so clear about the specific refining process. This requires a professional alchemist, and I always buy it from them."

Cao Mao began to understand a little. For nobles like these who took the medicine, they had special death-defying medicine masters to make the medicine for them. These medicine masters were the real professionals.

Although Pei Xiu is also proficient in this, he is not good at making it, but only good at eating it.

That would make things much simpler.

Cao Mao actually knew a super master in alchemy, the kind that had never been seen before, the super alchemist Ge Hong.

However, this person has not been born yet, and I am afraid that he will not be born for more than ten years.
Are there still professional alchemists nowadays?
Of course there are. Pei Xiu alone knows of dozens of them.

"The best among them is the Prince of Dongping."

"who???"

Cao Mao widened his eyes and looked at Pei Xiu in astonishment.

"The King of Dongping is the best at refining powder. He even wrote several powder recipes himself, and he is well-known throughout the world. In the past, I liked to buy from him. His powder is the best."

King of Dongping.

Cao Mao pondered for a moment and suddenly remembered who this was.

Cao Xi was the son of Cao Hui, King Ling of Dongping, and the grandson of Emperor Wu of the Han Dynasty, Cao Cao.

To be honest, Cao Mao had to politely call him uncle.

Well, it’s the royal family that’s taking the lead in refining and dispersing it, right?
At this moment, Cao Mao didn't know how to complain about this matter.

I actually have an uncle who is a death-defying master.

He immediately issued an order, requiring King Dongping to come to Luoyang immediately.

In addition to the King of Dongping, Pei Xiu also knew several excellent powder makers. What Cao Mao did not expect was that Huangfu Mi also knew how to make powder.

No way, he also took the medicine? Could his illness be a result of taking the medicine?
In addition to these two, there are many folk refining masters, and Pei Xiu's list is quite complete.

Cao Mao gave orders to these people one by one and called them all over.

But before gathering these people, Cao Mao really wanted to meet with Huangfu Mi.

He could understand others, but Huangfu Mi, what's wrong with you?!

Two world-class celebrities today, the father of cartography took powder, and you, the father of acupuncture, also took powder, right?
Huangfu Mi was in Luoyang, and he even served as the imperial physician, so he was soon brought to Cao Mao.

Pei Xiu happened to be the writing official.

Huangfu Mi could understand Cao Mao's greetings by observing his lip movements. After a brief greeting, Cao Mao asked, "Mr. Huangfu, are you also willing to be dismissed?"

Pei Xiu hurriedly wrote and then showed it to Huangfu Mi.

Huangfu Mi shook his head, "I am not easily convinced."

Cao Mao then asked, "What about Pei Xiu's claim that you are good at refining powder formulas?"

Huangfu Mi looked helpless as he watched Pei Xiu finish writing.

He hurried to explain.

It turned out that unlike Pei Xiu and others who took the powder as a leisurely thing, Huangfu Mi and others were studying the prescription and preparing it as a real medicine.

In fact, the original creation of Wushisan was to be used as medicine. Those stones can actually be used in medicine.
Huangfu Mi went there to cure his illness, while Pei Xiu went there to get sick.

Cao Mao suddenly understood.

This was still acceptable, otherwise, the filter of Huangfu Mi as a medical expert that he had a good impression of would be shattered.

Cao Mao then told Huangfu Mi about the ancient prescriptions he knew.

Huangfu Mi is much more professional than Pei Xiu Ke. He even has his own "laboratory" and many supporting tools.

However, according to Huangfu Mi, although he is studying this aspect, his research is not too deep and is still in the initial stage. Compared with the most professional people, he is still a little behind.
Cao Mao also understood that it seemed that he had to wait for the King of Dongping to arrive.

This one is the most professional.

He gathered all the scattered teachers from all over the country to his side. On the one hand, it was to prevent them from harming the famous scholars from all over the country. On the other hand, it was to let them conduct chemical experiments professionally. With these professionals, Cao Mao felt that it should not be too difficult to complete nitrogen fertilizer and phosphate fertilizer.

After all, what these people made is much more complicated than those two fertilizers. If they can make it, there is no reason why they can't make these two fertilizers.

From the frequent records of various ghosts and monsters during the Wei and Jin dynasties, we can tell that the formula of the Five Stone Powder they used might have contained something that caused them to hallucinate. Well, something that can't be said openly, Cao Mao felt that this thing was much more complicated than chemical fertilizer! !
Next, we just have to wait for these guys to arrive in Luoyang.
