It was afternoon!

On the open space in the front yard of the government office.

Several large tripods stand on the left and right.

A pile of firewood was placed next to it, and a ox cart was filled with green salt ore, as well as some other objects.

Ying Ziye, Jian Jiu and the officials, and craftsmen who refine salt gathered here.

"Young Master, I've found you."

The official said respectfully, reaching out to attract several craftsmen next to him.

"Xiaomin greets His Highness the Eighth Prince!"

A group of craftsmen fell to the ground one after another.

"Yeah, get up!"

Ying Ziye said politely.

"Today I will teach you a way to purify refined salt."

"The first step is to crush the salt ore!"

Ying Ziye raised his hand slightly and ordered the guards on the side to repeatedly crush the salt mine with a sledgehammer.

"The second step is to put it in water and boil it, and melt the green salt and separate it from the impurities."

After Ying Ziye said that, several personal guards threw the thinly broken green salt into the boiling water in the cauldron.

Gulugulu!

"Go and get some water and soil, splash the water on the burning firewood, and then cover it with a layer of soil."

"Here!"

A group of guards fetched water and shoveled soil.

Then, according to Professor Ying Ziye's method, the burning firewood was wet but not completely wet.

But the flames dissipated, but they were still red.

Then, under the guidance of Ying Ziye, a layer of loess was covered with.

"The method I teach you now has nothing to do with salt making, but to make charcoal."

"It makes the firewood unable to burn fully, and charcoal is formed, which is easy to ignite."

"But to make a lot of charcoal, then some containers are needed to burn it."

"You can use a fire kiln to burn charcoal in the future, and the output will be even greater!"

The officials and the salt craftsman nodded to express their understanding.

It took about a moment.

Ying Ziye felt that the time was almost the same, so he casually said, "Divide the loess open!"

"promise!"

When the soldiers took the order and dialed the loess, the original firewood was extremely dark, like ore.

"this……"

For a moment, everyone present was shocked and looked at the scene in disbelief.

Ying Ziye smiled slightly, but did not explain too much, and continued to instruct: "Currently steam the green salt and remove all the impurities on the surface."

"promise!"

The soldiers continued to be busy as Ying Ziye told him.

The item of steaming and cooking green salt lasted nearly five or six times.

It is almost difficult to see some impurities on the surface.

"Continue to steam and cook, and then put all of this charcoal on!"

As he finished speaking, all the craftsmen showed surprise on their faces.

"This... in this way, wouldn't the steamed green salt become cloudy again!"

"Oh... I'm afraid all my previous efforts will be wasted."

"Can you say that the Eighth Prince's move has other mystery?"

As the craftsmen were suspicious, their eyes kept staring at each other.

I was afraid that I had missed any details!

As time passed, the clear water in the cauldron gradually began to boil.

However, what is surprising is that these things that the Eighth Prince called charcoal were actually covered with a very fine layer of impurities.

If they hadn't observed it carefully, they wouldn't have noticed this subtle change at all.

"this……"

"What's going on!"

The craftsmen were puzzled and secretly speculated.

But with a scream, everyone's attention was once again attracted.

"Look, there are more and more impurities on this charcoal!"

As he said that, the man took out a string of 150 cents and submitted it to him.

The curved plow is of good quality and cheap price. One rack costs only 150 cents, which can be affordable.

He had seen a farming land at home, and he used a curved plow. The speed was flying. He tried to borrow it and found that it didn't take much effort to plow the land with a curved plow.

So today, the man got up early and rushed over!

The young man took the curved plow from the official, and the young man went home cautiously as if he was holding a treasure.

"The Eighth Master is really a god!"

"Not only was a new salt-making method invented, the snow-white fine salt has a higher purity, lower price than before, and the output is so amazing."
Chapter completed!
