Looking at the not-so-white crystals mixed with stone foam in the small ceramic basin, Han Cheng looked conflicted.

It looks somewhat similar to the brine in our impression, but even if these things are really brine, they still cannot be used to make tofu because there is too much stone foam mixed in it.

If you use it to order tofu, you might end up choking on it.

Han Cheng looked at it carefully for a long time but couldn't figure out what it was. He then poured some clean water into the small ceramic basin, and the white crystals quickly disappeared.

After melting and settling for a while, the stone foam stayed at the bottom of the small basin.

Han Cheng asked someone to clean the previous pottery jar, then carefully poured the water into the jar, and then started to burn it.

All the sediment at the bottom of the pottery basin was poured out.

After a while, all the water inside evaporated, leaving only a layer of white crystals at the bottom of the tank.

Unlike the white color of salt, the white color of this crystal is somewhat yellowish.

Now after evaporation, the things obtained look more like the brine seen in later generations.

Han Cheng looked at the thing carefully for a while, then scratched his head, quite surprised.

The brine that was imagined to be extremely difficult to deal with was produced just like that?

It actually became the first thing to appear among all the things needed?

Sure enough, sometimes the door is actually ajar. Things that seem difficult are sometimes not that difficult when you actually try them.

For example, Han Cheng is now dizzy and seems to have succeeded...

Han Cheng, who felt dizzy for a while, put down the brine in his hand, and continued to boil it according to the previous method.

After three tanks in a row, we obtained more than half a pound of what looked like brine.

When making tofu with brine, you don’t need to put too much salt, otherwise the tofu will be bitter and inedible.

So what we have collected now is enough to order a lot of tofu.

After waiting here for a while, and waiting for the people who were boiling salt to prepare the salt, Han Cheng and others headed towards the tribe.

I was full of worries when I came here, but I felt relaxed when I left.

Now the most difficult part of preparing brine seems to have been solved by myself, and the rest just needs to be done step by step.

The most time-consuming part of this is the stone mill. As soon as the stone mill is ready, you can start making tofu.

Han Cheng walked back while thinking about these things in his mind.

However, with the hammer and chisel, and with the woodworking skills, after half a day, I should be able to carve out a rough outline of the door...

What's going on?

After walking into the tribe carrying a pottery jar filled with brine, Han Cheng, who was concerned about the progress of the stone mill, looked towards the place where the wood was working.

Instead of hearing the familiar sound of iron chisels and stone hammers, I saw a few people squatting on the ground with their heads in their hands.

The millstone that he had imagined had a rough outline carved out did not move at all, and several pieces of granite were still intact.

Han Cheng was full of confusion after seeing this scene. What were Mu Tou and the others doing?

"Son of God!"

Shi Tou, who was squatting on the ground with his hands on his head, looked up towards the entrance of the tribe out of habit, and saw Han Cheng who had just walked into the tribe. He was very distressed, but now he shouted happily as if he had seen a savior.

Wu, Bo, and Mu Tou, who were all sweating because of the small circle, looked up in surprise and looked towards the door when they heard Shi Tou's cry.

Among them, the man named Mu, who was holding a hammer and a chisel, stood up from the ground and walked quickly towards Han Cheng.

Those who didn't know would think that he wanted to do something to Han Dashenzi.

"God...Son of God, I can't draw a circle..."

Mu Tou came to the gate to greet him, speaking with a look of shame on his face, as if he was about to cry.

Looking at the hammer and iron bar in Mu Tou's hands, Han Cheng generously forgave Mu Tou for the delay in the construction period and expressed full understanding of his difficulties.

Mu Tou has been put in such a difficult situation. As a magnanimous person, how could he possibly blame Mu Tou?

This is really inhumane.

Well, sometimes admitting your mistakes with a brick-moving knife can often achieve twice the result with half the effort.

For example, the wood of today, or Washington who, many years later, chopped down his father's favorite cherry tree to test whether his axe was sharp, and then went to his father to apologize with the axe...

After this little incident, Han Cheng quickly understood what difficulties they had encountered.

Han Cheng's face twitched. He thought that everything would be fine after he explained everything. Who could have thought that they would be collectively troubled by such a small circle?

This matter is really a bit laughable.

Looking at the people who were looking at him eagerly, Han Cheng felt that he really needed to show off his skills!

Han Dashenzi rolled up his sleeves, exposing his arms, and picked up the long, thin stone that looked like a slate pencil.

Just when a few people were waiting and thinking that the Son of God was going to show his skills and draw a smooth circle easily and casually with a stroke of the brush, Han Da Shen Zi left here cleanly and walked towards the room.

Looking at the back of the Son of God walking away quickly, those who had never eaten oranges were all stunned.

Could it be that this seemingly simple circle has stumped even the Son of God?

Otherwise, why would the Son of God just leave without saying a word?

Fortunately, Han Cheng came out of the room not long after and walked quickly towards here.

There was no orange in his hand, but a piece of thin hemp rope.

Under the curious and puzzled gazes of several people, Han Cheng made a small noose with one end of the rope and tied the other end to the thin stone pen.

Find a tree trunk as thick as a little finger and insert it into the noose, and a simple compass is made.

Han Cheng doesn't have the ability to draw a circle by hand. This skill is usually only possessed by master painters or senior teachers who have taught mathematics and geography for many years.

Fortunately, one of the characteristics of human beings is the use of tools.

Under the inquiring gazes of several people, Han Cheng first wiped off the messy marks on the granite, and then measured it for a while to roughly find the center position of the stone.

Hold the small stick upright, hold it tightly with your hand, use your other hand to hold the slate pencil to straighten the rope, then use your hand to apply force and make circles around the stick.

Under the astonished gaze of Wu, Shitou, Bo and Mu, a very standard circle appeared on the stone slab so easily.

Several people looked at the circle, at the tools in Han Cheng's hand, and then at each other. They were all silent for a moment.

The problem of hair loss that made them sad was solved so easily?

(There are some minor problems with the description of the production process of brine. Book friends should not be too serious, and do not try this method, because I can't guarantee that the result is brine, after all, there are a lot of impurities in the salt mine...)
