When I got up the next day, the sun had come out of the east.

Not very bright, the sallow little face is compared to Han Cheng, who loves to dream.

However, the temperature is quite high, at least seven or eight degrees higher than yesterday.

By noon, it was already warm outside.

Some old people who were afraid of the cold came out of the room, squatting at the base of the wall with the soles of their shoes, basking in the sun.

Some of the stronger people even took off their thick leather jackets.

Some women in the tribe are taking this opportunity to boil hot water and bathe the minors in the tribe.

Because of the high temperature, I don't even have to go to the bathhouse.

At such temperatures, the snow around was rapidly melting, and by 10 noon, it had become much thinner, and in some places it had been covered with dead grass.

According to this trend, it only takes three days at most for the snow to melt clean, and the spring ploughing in the tribe can begin.

In the tribe, Stone looked a little excited and picked up a stone pen, drew a bar on the simple calendar he had made, and carved some words underneath.

Of course he was excited, and in this winter he thought of a way that might well make the bark softer and easier to break.

As a result, due to the cold weather, it has not been possible to implement it until now.

Now that the weather is finally starting to get warmer, it won't be long before he can start proving his ideas and making better paper.

It was not only the Qingque tribe that was excited because of the warmer weather, but all the tribes around that felt the warmth became excited.

They are running out of food, some of them are running out, and now that the weather is starting to get warmer, it is undoubtedly excellent news for them.

Some tribes that lack food have already taken advantage of this opportunity to go out to search for food.

In winter, sometimes some birds and small animals freeze and starve to death.

When the snow melts, the snow-covered stuff is exposed and becomes food for the hungry.

Han Cheng, who was happy in the sun for a while, frowned, because he suddenly remembered what he had learned in geography in high school, about Leng Feng and Nuan Feng.

Before the cold front crosses, a warm air mass envelops the land, and the temperature rises.

After the heating mass has passed, it is the cold air mass that pushes the heating into it.

When the intersection of cold and warm air currents transits, there will be strong winds, rain and snow, and when the cold air mass behind transits, the weather will be clear, but the temperature will drop a lot, extremely cold, and when encountering some extreme weather, it can also form a cold wave.

But don't be a cold front to cross the border.

After thinking back for a while about the knowledge that he didn't remember very clearly, Han Cheng thought in his heart.

It was a trivial matter to delay spring plowing for a few days, and what worried him the most was the trade team that went out.

When the cold front crosses, they say that they will not suffer a lot of sin.

And according to the situation of today's rising temperature, this mass of warm air is bound to be not small, and the cold air flow that can push such a warm air to go will naturally not be small.

After the weather warms up, there will be a sudden spring cold, which is really a trick.

Thinking about these things in his heart, after waking up the next day, the first thing Han Cheng did was to feel the temperature.

The temperature hasn't changed much from yesterday, it's still warm.

Could it be that I am thinking wrong?

After Han Cheng stood here and felt it for a while, he muttered to himself.

If you really think wrongly, then you will suffer less.

Picking up the little pea who woke up from sleep, and after teasing him every day, Han Cheng carried him out of the room.

The ground was a little soft, and it didn't freeze much last night.

Carrying the little one to the cave used as a cafeteria, the industrious Fire Er is burning a fire there.

When the weather is cold, it is more attractive to sit in front of the stove and light the fire.

If you can bury two sweet potatoes in the fire, or put a stick on a stick to put on a steamed bun that has already cooled at home, then the fire will become even more attractive.

However, this morning was an exception, except for Huo Er, who was burning the fire, and by another wood stove not far away, the stone was also squatting there to make a fire.

What is this guy doing here today?

What's cooking in the jar?

Han Cheng hugged the little pea, walked over with doubts, leaned to the side, let the little pea go to the side, grabbed the lid of the pot with his other hand, and lifted it with his hand.

After the white mist rose, the scene inside came into Han Cheng's eyes.

Bark?

Han Cheng's eyes widened.

In this stove where the stone is burned, it is not food, but tree bark.

This guy, what is boiled bark for? Do you want to remember the bittersweet memories and drink a bowl of bark soup in the morning?

Han Cheng's face was blank.

It wasn't until I saw that the bark boiled inside was the kind of peeled off outer layer, and then I suddenly showed a sudden color.

It turned out that this guy was fiddling with paper.

However, do you need to boil the bark of the tree with water when making paper?

Han Cheng really doesn't know this, but it's always good to have the courage to try new methods.

Because a lot of new things are tried again and again.

Moreover, Han Cheng really doesn't know much about papermaking, and the papermaking process he made before is very simple, and there is great room for improvement.

Putting the lid back on, Han Cheng began to talk to the stone, saying something about papermaking.

After studying on this for several months, compared to the extremely difficult flying sky, the stone is on the paper, and I really have a lot of insights.

He felt that the paper he had made before was too thick and too the one hand, because he had too much pulp when making paper, and on the other hand, the pulp itself was too hard and too rough.

So he began to figure out how to make the pulp softer.

After trying several methods, the stone came up with the idea of 'boiling'.

Foods such as hardy raw meat and hardy soybeans become fluffy when cooked in a large vat and water, so Ishiki wanted to try it this way.

After listening to what the stone said, Han Cheng couldn't help but nodded, feeling that it made sense, it seemed that it was still very wise to leave this matter to the stone before.

I am afraid that these barks will not be cooked, and the stones have been boiled for a long time.

It was not until breakfast was ready, and everyone had eaten breakfast for a while, that the stones stopped firing.

The lid was simmered for a while before the lid was lifted to bring out the bark inside.

After soaking in warm water for a while, place it on a cutting board and cut it carefully with a copper knife.

After cutting it, put it in the stone mortar, and start to do it a bit, Han Cheng followed to the side to watch the excitement, wanting to see if it could be done this time.
