The entourage brought by Cheng Chumo pulled the carriage over, and the salt-making tools engraved on the wooden board by Tao Ran were all ready.

There were sieves for making salt, hammers, pots, buckets, rods, shovels, gauze, charcoal, and an iron mill.

"There is a natural salt mine on the river beach near the official road, let's go to the scene now, and I will show you how to make salt."

After Tao Ran finished speaking, he walked towards the river, and Cheng Chumo and others followed closely.

When I walked to the riverbank, I saw that the stones of the riverbank were full of shiny salt.

"Brother, can you send someone to fetch some salt?"

"Brother, those lumps of salt will eat the dead." Cheng Chumo roared loudly.

"Of course, poisonous salt will eat human life, everything in the world has a way to restrain each other, and the detoxified salt will not eat human life again." Tao Ran calmed down and said in a profound tone.

Tao Ran's calm appearance really frightened everyone, Zhang He was the first to run out, pulled out a horizontal knife and cut down the salt on the stone, a large piece of salt fell to the ground, and Zhang He sent the salt to Tao Ran.

"Everyone, look at it, I'm starting to make refined salt now."

Tao Ran picked up the hammer and slowly smashed the large pieces of salt into granules. Then put a little of these granular salts in the iron mill, press the wooden handles at both ends of the iron mill with both hands, and roll them back and forth.

The grains of salt, which had been crushed by the iron medicine, gradually changed color, from milky white to dark brown at the beginning.

Tao Ran put the dark brown salt powder into an iron bucket, added water and stirred it with an iron rod.

Then Tao Ran sealed another iron bucket with gauze, put the sealed iron bucket aside, and turned back to continue stirring the salt grains in the iron bucket.

When you can't see half a grain of salt in the iron tong to be stirred. Tao Ran lifted the iron bucket and carefully poured it into another iron bucket sealed with gauze.

After a while, the gauze was covered with gray-black slag.

Tao Ran took off the gauze, and the color of the solution in the barrel became significantly lighter, but there were still many impurities.

Tao Ran took another bucket and covered it with four layers of gauze this time.

The light-colored solution is stirred again with an iron rod and poured on a four-layer gauze bucket.

After four layers of gauze filtered the solution again, the color changed to light red.

Immediately afterwards, Tao Ran covered an iron bucket with a thick six-layer gauze, and slowly poured the light red solution into the six-layer gauze bucket, which was covered with red spots, which were bright and dazzling in the sunlight. The solution in the iron bucket has turned pale cyan.

At this time, the impurities of the salt mine have been removed, and only the key detoxification remains.

Cheng Chumo waited for a group of people, and looked at Tao Ran's movements like flowing clouds and water in a daze, and he didn't dare to make a sound.

If such a sacred method of salt production is interrupted, it will cause a curse.

Tao Ran held a funnel in his hand and fixed it above a clean iron pot. The pale cyan solution was poured into the funnel, and the solution flowed down the funnel into the iron pot.

Tao Ran dipped his fingers lightly and put it on the tip of his tongue to taste it. The original bitterness is gone, only the saltiness that it should be.

Tao Ran set up the iron pot and piled the charcoal into the bottom of the pot. When he squatted on the ground and was about to take out the lighter in his pocket to light it, he thought that there were spectators all around, and immediately dispelled the idea of lighting it with a lighter.

Tao Ran turned to look at the people who were staring intently.

"If you can't burn the fire, will you let me do it?" Tao Ran stood up and rubbed his waist and said.

Zhang He was the first to react, took out the fire and lit the charcoal.

"Brother is tired, come and sit down and rest for a while." Cheng Chumo smiled with a dark face, and eagerly came over to help Tao Ran to the carriage and sit down.

The charcoal under the pot became more and more intense, and it was not long before the solution was boiling and bubbling in the large iron pot.

"Brother Childe, how long will this fire burn?" Zhang He, whose face was flushed from the coals, asked.

"Keep burning the fire until you have boiled all the water and dried the pot." Tao Ran sat in the carriage and closed his eyes to recuperate, in fact, he was thinking about what to do next?

The method of making salt has been taught, and presumably the famous demon king of the mixed world in history will definitely receive him in person.

As a budding newcomer, he has to think of some preservation strategies to deal with an old fox from a thousand years ago.

"His grandmother's pot hasn't dried yet, so you guys go and cut down the dead tree by the river, carry it over and continue to burn the fire." Tao Ran was shocked by Cheng Chumo's loud voice and opened his eyes.

I saw Cheng Chumo circling around the iron pot, which made Tao Ran instantly think of the ants on the hot pot, which couldn't be more appropriate for Cheng Chumo.

Everyone worked together to carry the dead tree to the big iron cauldron, and Cheng Chumo didn't say a word, picked up the big axe and split the big tree into several sections with three strokes and five divisions.

Zhang He kept filling the chopping wood to the bottom of the pot, and for about half an hour, there was no churning and bubbling sound in the iron pot.

"Brother Childe, the water in the pot has been boiled dry." Zhang He stood up and wiped the beads of sweat from his forehead and said.

Hearing this, Tao Ran walked quickly to the big iron pot, at this time the iron pot was already red, and the salt grains at the bottom of the pot were about to solidify, and there was green smoke.

Tao Ran picked up a shovel casually and continued to stir-fry at the bottom of the reddened pot, and every time he turned it, he used the back of the shovel to press the salt grains evenly, and so on many times.

"It's time to turn off the fire." Tao Ran opened his mouth and said to Zhang He.

Although the fire has been extinguished, the reddened iron pot still maintains a high temperature.

Tao Ran's face was red from the iron pot roasting, and he was covered in sweat. Cheng Chumo politely handed over a towel that had been chilled with cold water, and asked Tao Ran to wipe the sweat beads on his forehead to cool down his body.

Tao Ran ignored his kindness, and continued to use a shovel in the big iron pot, tumbling and stirring the salt grains.

The fiery red iron pot quickly returned to its original dark color, and at this time, Tao Ran could clearly hear the sound of "rustling" when he rolled with the shovel.

Tao Ran shoveled out a little salt with a shovel and tasted it himself.

"Well, that's fine. Now these grains of salt can be eaten with confidence. Tao Ran took the towel in his hand and wiped the sweat on his face.

As soon as he heard Tao Ran say that it was edible, Cheng Chumo stuffed the salt grains in Tao Ran's shovel into his mouth.

Although his eyes rolled with saltiness, he was reluctant to spit out the salt in his mouth.

"It's so fucking salty, Lao Tzu has never eaten salt of such purity, I don't know how many times better than official salt? This is a few points better than green salt, which is used to gargle with wicker, and it is very expensive. Cheng Chu covered his mouth silently and said angrily.

"Brother, your method of making salt is really magically tight, just a few simple iron buckets, iron rods, shovels, and iron pots can turn poisonous salt into table salt, today is really an eye-opening for my brother, my brother will definitely report to my father, no, report to the general, let the general repay my brother."
