If Li Zheng said this, Li Tai would not be so disappointed.

After thinking about it carefully, it seems that as Li Zheng said, neither the former crown prince Yang Yong nor the previous Li Jiancheng ended up being very good.

It just so happened that both princes were assisted by Li Gang.

When Li Tai thought about it this way, he was not so disappointed.

Life seems to be full of hope and sunshine again.

Let Li Gang stay by the prince's side.

Li Ke walked and said, "A team of soldiers came to the court and said they wanted to see you."

"See me?" Li Zheng stopped grinding the peppers.

Li Ke nodded, "This army brought some things over and wrapped them in black cloth. I don't know what it was?"

He handed the small millstone in his hand to Li Tai and asked him to continue grinding the peppers.

Li Zheng washed his hands and hurried towards the entrance of the village.

Five thousand troops stood outside the village, and there were eunuchs wearing the palace eunuchs.

The general led by the leader walked up to Li Zheng and said, "Marquis of the County, this is what Your Majesty asked me to give to you."

"What?" Li Zheng looked at these things wrapped in black cloth.

"Your Majesty will give you a steady stream of delivery in the future. Please prepare early."

After saying that, the five thousand soldiers turned around and left in an orderly manner.

Only these dozen eunuchs were left.

Li Zheng was still stunned and did not come back to his senses. He looked at the eunuchs and said, "Why don't you leave?"

The eunuchs smiled and said, "Your Majesty has an order, let us help the county guards."

I opened a corner of the black cloth and looked carefully. It turned out to be huge white crystals.

The eunuch said: "County Marquis, these are salt mines."

The color is yellow and there are many impurities. It should be the silver mine sent from Qinghai Lake.

Now that I understand everything, I will look at these eunuchs again.

He said he was staring at me and he was still helping me?

Isn’t it just to refine some fine salt? Li Shimin is still afraid that I will cut corners?

Li Zheng waved to Li Ke and said, "Pull all these things into Princess Changle's fiefdom."

Li Ke called the village guards to do business, and all the sixteen heavy things were taken away.

These are natural salt ores. There were coarse salt in the Tang Dynasty, but there were very little fine salt. Even fine salt was a patent that only the powerful royal family could enjoy.

This kind of salt ore is also called green salt. It is easy to cause stomachache when eaten directly. There are many impurities in it and it needs to be refined before it can be eaten.

Li Zheng asked Li Ke to circle a place to extract fine salt.

The eunuch in the palace said to Li Zheng: "County Hou, we can do the next thing, and we don't have to bother outsiders."

Li Zheng pointed at Li Ke and said, "He is His Highness, not an outsider."

"Your Majesty has an order, so that the county guard can only come with us."

Li Ke had no choice but to leave. Before leaving, he said to Li Zheng: "I have seen these eunuchs, and they are all confidants of the father."

A piece of land was wrapped with a fence and a simple greenhouse was built.

The eunuch dressed in black eunuch uniform smiled and said, "Marrior, can we refine fine salt?"

Li Zheng dipped his fingers some broken salt mines, and then spit out after taking a bite.

These salts are bitter and astringent, and there are too many impurities inside.

Li Zheng said: "It's not so easy to refine fine salt. Do you think I can do magic? If you say it, just refine it."

Coarse salt is affordable in the market, but many people can't afford it, and fine salt is even more expensive.

Even ordinary powerful families cannot afford fine salt. There is a saying that fine salt is comparable to gold.

The first thing to do when refining fine salt is to remove impurities. Li Zheng wrote down what he needed to let the eunuch go to buy it.

The eunuch held the item in his hand and looked at the content written on it.

"I use these things to refine fine salt, and give them all the same and good things to me." Li Zheng said.

The eunuch looked at the things written on it and was a little puzzled: "What do the county marquis want to make for fifty big pots?"

"If you want to refine coarse salt into fine salt, one step that is indispensable is boiling salt."

The eunuch nodded thoughtfully and asked again: "There is nothing wrong with the others. But the old slave doesn't understand why the county marquis still needs so many dried fruits, three thousand silk cloth, thirty sows, forty hens, and wolfberry...?"

The old eunuch took a breath, "This..."

Li Zheng said: "These are all needed to refine fine salt."

The old eunuch said, "But this..."

"I tell you, it's the same as the ones, I can't extract this fine salt."

The old eunuch had no choice but to nod, leave in a hurry, come to Li Zheng's palace, and hand over Li Zheng's requests to Li Shimin.

Looking at the above content, Li Shimin also felt that it was very outrageous. What's the matter with refining fine salt?

The old eunuch said to Li Shimin: "Your Majesty, the county marquis said that the fine salt would not be extracted."

Li Shimin smiled coldly, "Okay, you Li Zheng! Take the opportunity to try to knock me, right?"

Li Lizhi, who was standing behind Li Shimin, glanced quietly and couldn't help laughing.

Queen Changsun glanced at her and said with a smile: "This Li Zheng is very real."

"How is it real?"

Li Shimin was so angry that he was itchy, "I don't believe it anymore. No one except him, Li Zheng, can extract fine salt?"

But when I calmed down and thought about it, it seemed that something was wrong.

Most of the fine salts today are extracted by the gentry by the sea, especially the Shandong gentry by the sea.

They can extract fine salt from sea salt.

The whole Guanzhong is so fine that there is very little salt.

It seems that there is really no one except Li Zheng.

Li Shimin slapped the table and suddenly didn't want to refine fine salt.

You don’t live well without fine salt.

Empress Changsun held back her smile and said, "Li Zheng didn't ask for gold, silver and money."

Li Shimin was so angry that he said, "If it were someone else, I would have been killed 800 times."

Li Zheng seemed to be testing Li Shimin's bottom line again and again.

Li Shimin suddenly discovered that Li Zheng, a kid, could live so many times under his nose, was a miracle.

After putting away this list, Li Shimin said: "Give him everything Li Zheng wants. If he can't bring out fine salt, my military law will deal with him."

Li Lizhi asked in a low voice: "Father, what military law?"

Li Shimin said: "Li Zheng is the Central Army General of the Longwu Army. If he cannot make fine salt, he must deal with it with military law!"

Seeing Li Lizhi's expression was worried.

When my daughter grows up, she can't keep it, and even her own daughter stands on Li Zheng's side.

Li Shimin walked out of Lizheng Hall angrily and tried to suppress his anger while practicing Tai Chi.

Refining fine salt requires many steps.

Li Zheng was busy mashing the salt ores first and putting them in water to wait for dissolution.

After one bucket of water is saturated, replace it with another bucket of clean water and then dissolve it until saturated.

Impurities that cannot be dissolved in water.

This is the first step to remove impurities.

It took only half a day to deliver everything Li Zheng needed in the palace.
