Looking at these not-so-white crystals mixed with stone foam in the small clay pot, Han Cheng was puzzled.

It still looks a little similar to the salt brine in my impression, but even if these things are really salt brine, there is no way to order tofu because there are too many stone foams mixed in it.

If you use it to order tofu, you won't lose your teeth when the time comes.

After looking at it carefully for a while, Han Cheng didn't see a reason, and put some water into this small clay pot, and these white crystals quickly disappeared.

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

Han Cheng asked the previous clay pot to be brushed clean, then carefully poured the water into the clay jar, and then began to burn it.

The sediment at the bottom of the pot was poured out.

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

Unlike the white of salt, this crystalline white is a little yellowish.

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

Han Cheng carefully studied this thing for a while, and then scratched his head, quite surprised.

The salt brine, which was extremely difficult to deal with in the imagination, was tinkered out like this?

It was the first of many things needed?

Sure enough, sometimes the door is actually hidden, and sometimes it seems difficult to do it, but sometimes it is not necessarily that difficult to do.

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

Han Cheng, who was dizzy for a while, put down the things in his hand that should be salt and brine, and then continued to boil according to the previous method.

After three cylinders in a row, I got more than half a catty of suspected salt and brine things.

When ordering tofu with brine, you don't need to put much salt to marinate, otherwise the tofu will be bitter and inedible.

So the ones collected now are enough to order a lot of tofu.

After waiting here for a while, after the few people who boiled the salt had finished the salt, Han Cheng and the others headed towards the tribe.

When I came, I was very worried, and when I went back, I was relaxed.

Now the most difficult salt brine in my imagination seems to have been solved by myself, and the rest of the things just need to be done step by step.

One of the most time-consuming is the stone grinding, as long as the stone grinding is ready, you can start making tofu.

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

However, with a hammer and a hammer, according to the craftsmanship of the wood, after most of the day has passed, it should be possible to chisel a fan out of a rough outline......

What's wrong with this?

After walking into the tribe with the clay pot containing salt brine, Han Chengcheng, who was concerned about the progress of the stone grinding, looked at the place where the wood was working.

Instead of hearing the familiar sound of hammering stones, I saw a few people crouching on the ground with their heads in their hands.

In his imagination, the stone mill, which had been chiseled out of a rough outline, did not move at all, and a few pieces of granite were still in good condition.

Han Cheng, who watched this scene, was full of doubts, what are they doing?

"Miko!"

Squatting on the ground holding the stone with his head, he habitually looked up at the door of the tribe, and when he saw Han Cheng who had just walked into the tribe, he was distressed, as if he had seen a savior, and shouted happily.

Wu, Cripple, and Wood were embarrassed by the small circle and sweated all over their hearts, and when they heard the cry of the stone, they all looked up in surprise and looked at the door.

Among them, the wood carrying the hammer and iron drill stood up from the ground and walked towards Han Cheng quickly.

I didn't know, and I thought he was trying to do something to Han Dashenzi.

"God... Miko, I can't draw a round ......."

Wood greeted him at the gate, and said with a look of shame, as if he was about to cry.

Looking at the hammer and hammer in Wood's hand, Han Cheng generously forgave Wood for the delay in construction and expressed full understanding of his difficulties.

Wood is embarrassed to look like this, how can he, as a generous person, blame Wood again?

That's really impersonal.

Well, sometimes carrying bricks to admit mistakes can often achieve twice the result with half the effort.

For example, the wood now, and I don't know how many years later, in order to test whether the axe is sharp, after cutting down my father's favorite cherry tree, I carried the axe to Washington, D.C., who confessed his mistake......

After such a small turmoil, Han Cheng quickly understood what problem they had encountered.

Han Cheng's dough twitched, he just thought that he would be able to explain the things after he finished explaining, who would have thought that they would be embarrassed by the small circle collectively?

This thing is really a little laughable.

Looking at the few people who were staring at him, Han Cheng felt that it was necessary for him to show his skills!

Han Dashenzi rolled up his sleeves, exposed his arms, and picked up the slender stone like a stone pen.

Just when a few people waited and thought that Shenzi was about to show off his skills, and after a big stroke of the pen, he drew a mellow circle very easily and casually, but Han Dashenzi left here cleanly and walked towards the room.

Looking at the back of Miko who was leaving quickly, several people who had never eaten oranges were stunned.

Wouldn't this seemingly simple circle be embarrassing for the Son of God?

Or why didn't the Son of God leave without saying a word?

Fortunately, it didn't take long for Han Cheng to come out of the room and walk briskly all the way here.

Instead of an orange in his hand, he held a thin piece of hemp rope.

Under the curious and puzzled gazes of several people, Han Cheng pulled out a small rope sleeve from one end of the rope, and tied the other end to the thin stone pen.

I took a tree trunk the size of a small thumb and inserted it in the rope sleeve, and a simple compass was made.

Drawing a circle with his bare hands, Han Cheng does not have this ability, this skill is generally only done by those master painters, or senior teachers who have taught mathematics and geography for some years.

But the good thing is that one of the great characteristics of people is the use of tools.

Under the inquiring gaze of several people, Han Cheng first wiped away the messy traces on the granite, and then compared them for a while, roughly finding the center of the stone.

Stand the stick there, press it tightly with your hand, straighten the rope with a stone pen in the other hand, and then use force in your hand to make a circular motion around the stick.

Under the amazed gaze of witches, stones, lameness, and wood, an extremely standard circle appeared on the stone slab with ease.

A few people looked at the circle, looked at the tools in Han Cheng's hands, and then looked at each other, and they were all a little quiet for a while.

The matter of their melancholy hair falling out was easily solved?

(There is a little problem with the production process of salt brine, don't be too serious, and don't try it with this method, because I really can't guarantee that this is salt brine, after all, there are a lot of impurities in the salt mine...... ）
