In the afternoon of the same day, Sun Qian gathered more than 1,000 people, all of whom were officers and soldiers in the imperial court, to wait outside the East Palace.

In his words, what could be more reassuring than one's own people? Listening to Li Chengqian's words, this matter is very important, so for the sake of safety, it is better to be your own people.

So he chose officers and soldiers, and of course, the money given to these people is still indispensable.

These people formed a large circle, staring at Li Chengqian in the center.

They had heard that Li Chengqian wanted to make salt, but no one believed it, after all, the prince was only eight years old, isn't this salt making an adult's business? What does he know as a child?

More than 99 percent of the people think so, but they are officers and soldiers, and they dare not say this to Li Chengqian, because they will be killed.

Li Chengqian had already seen through these people, and he didn't care too much about it, because everything was based on facts.

At this time, Li Chengqian asked people to set up an iron pot, and a large piece of mineral salt was placed in a wooden basin next to it.

How did these 1,000 people know what he wanted to do? They all expressed their surprise, and these people also recognized the salt mine, which was inedible.

And that mineral salt was found by Li Chengqian and asked Sun Qian to find it.

This thing is called poisonous salt in the Tang Dynasty, and the common people will not eat these things, only wild animals will eat a little to supplement the salt. But don't dare to eat too much, you'll die.

At? Mineral salts in nature contain many impurities and toxic metals.

The people of Datang are helpless about this, but for Li Chengqian, it is just a simple matter that cannot be simpler.

"Come on, smash these mineral salts for me!"

As soon as he gave the order, everyone watched Li Chengqian performing with a puzzled mood, although they had doubts in their hearts, they didn't dare to ask.

Soon the salt is crushed and then poured into the water.

Li Chengqian ordered Xue Rengui to stir, and the clarified water immediately turned turbid purple.

"Your Royal Highness the Crown Prince, are you okay with this?"

Sun Qian asked with suspicion.

Li Chengqian ignored him, but continued: ?" Pour into this bucket. ”

They had already covered the top of the barrel with three or four layers of linen in advance, and the cloudy solution was poured into it, leaving a layer of earthy substance on the linen.

These are toxic minerals, and there are some impurities, which are insoluble in water.

Looking at the water in the barrel, it is much clearer than before.

"One more time."

Xue Rengui filtered it again according to the instructions, and the solution had become very clear, much clearer than clean water.

The crowd was still wondering, what was this doing, why did it pour twice?

Seeing that the water is getting clearer and clearer, Li Chengqian feels that it is not enough, to propose good quality salt, these are not enough, there must be some heavy metals in it, but the content is definitely not as high as before.

So he ordered to filter it a few more times.

Whereas? The final step is to filter the solution with charcoal.

It was a basin of colorless liquid.

Li Chengqian got a little bit with his hand and was about to put it in his mouth.

was stopped by Sun Qian.

"His Royal Highness the Crown Prince, is this okay? This salt water is poisonous! ”

"It's okay, just look at it!"

I saw that he put it in his mouth and tasted it, there was no bitter taste, only a faint salty taste, which should have been filtered clean.

Everyone looked at what Li Chengqian had done with great amazement.

His eyes were full of shock, he had just heard that Li Chengqian wanted to refine salt, but this was the first time they had encountered this kind of operation.

"Someone! Pour these into the pot and boil dry! ”

The next step was to boil, and the brine was quickly poured into the pot, and the fire underneath began to burn.

People all looked at Li Chengqian with a strange expression, what the hell was he going to do?

After a quarter of an hour, the water was boiled dry, and all that remained in the pot was fine salt as white as snow.

Wow

The crowd was in an uproar, is this white and immaculate thing salt?

You must know that in ancient times, there were a lot of impurities, and it was rare to see such white salt.

"It's salt! It turned out to be salt! Edible! ”

Sun Qian stepped forward, excitedly dug out a piece, and put it in his mouth, so salty that he frowned, but he was reluctant to spit it out.

"It's salt! It turned out to be salt! ”

Everyone was in a sensation, they had never seen anything to make salt, and now they have a long insight.

Someone else walked over, held the thin salt in his hand and said, "The quality of this salt is the highest I have ever seen in my life!" ”

In this way, the shock of the crowd was even stronger.

The prince was able to make salt of such quality, and the method used was so simple! To the surprise of everyone.

There is something more important at the moment.

"Do you remember the steps of making salt?"

When Li Chengqian asked this, everyone reacted, and Li Chengqian called them over to learn how to make salt.

Everyone hadn't woken up from the shock yet, and when Li Chengqian finished speaking, his mind began to run out of points.

"Congratulations to the host, ten points have been awarded!"

"Congratulations to the host, ten points have been awarded!"

"Congratulations to the host, ten points have been awarded!"

……

10,000 points in hand, this is better than anything else, if it is not for comprehensive consideration, then he may get more points.

"His Royal Highness the Crown Prince is talking to you, didn't you hear me?"

If it weren't for Xue Rengui's reminder, these people would probably still be shocked.

"Yes, yes, yes! Your Highness the Prince, we get it! ”

Li Chengqian said again: "Very good, the entire salt industry of Datang will depend on you in the future!" Your deeds will go down in history! ”

As soon as these words came out, a thousand people were excited, after all, these words came out of the prince's mouth, and the meaning was different.

Of course, this thousand people is only the first wave, first solve the current crisis, and then in the future, you can increase production, it is not impossible.

"Moreover, all those involved will be subsidized, but one thing you must remember is that this method must not be leaked, otherwise it will be severely punished!"

"Yes"

How dare people disobey, the leak will not end well, everyone knows it.

"Alright, you had to remember better, I want you to rush to the salt mines now, and get the first wave of salt there!"

This wave of salt will make up for the gap of the Wang family, and the price will not be set too high, and the quality will definitely be better.

Fine salt can be more pleasing than coarse salt, the same thing, you have better quality than others, the price is lower than others, and it is officially produced, people don't buy your things, that's stupid.

"Yes!"

The people answered.

At the same time, a little yellow door shouted:

"Your Majesty, Her Royal Highness the Queen has arrived!"

What did Li Shimin come to him for at this time? He couldn't figure it out either.

But when I thought about it, it was probably because of the salt.

"Alright, you all go down!"

"Yes!"

Only then did everyone retreat and go to the salt mine to deal with it, while Li Chengqian went up to greet Li Shimin and Empress Changsun. Take a hundred plating to read the latest chapter of the "Tang God-level Prince Claw Book House" for free for the first time.
