Chapter 606: The Interchange of Air-conditioning and Heating
When I got up the next day, the sun had already emerged from the east.
Not very bright, his sallow little face is comparable to that of 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 and squatted at the base of the wall, holding the soles of their shoes and basking in the sun.
Some strong people even took off their thick leather jackets.
Some women in the tribe took this opportunity to heat hot water and bathe the minors in the tribe.
Because the temperature was relatively high, I didn't even need to go to the bathhouse.
Under such temperatures, the surrounding snow is melting rapidly. By ten minutes past noon, it has become much thinner, and covered with dead grass has been exposed in some places.
According to this trend, it will only take three days at most for the snow to basically melt away, and spring plowing in the tribe can begin.
In the tribe, Shitou looked a little excited and picked up a slate pen, drew a line on the simple calendar he made, and at the same time carved some words below.
Of course he was excited. During this winter, he thought of a way that might make the bark softer and easier to crush.
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 testing his ideas and making better paper.
It's not just the Qingque tribe who are excited because of the warming weather. All the surrounding tribes who feel the warmth are all getting excited.
They don't have much food saved anymore, and some of it is almost finished. Now the weather is starting to get warmer, which is undoubtedly excellent news for them.
Some tribes that were short of food had already taken advantage of this opportunity to go out to search for food.
In winter, sometimes some birds and small animals die of cold and starvation.
After the snow melts, these things covered by the snow will be exposed and become food for hungry people.
Han Cheng, who was happily basking in the sun for a while, frowned because he suddenly remembered what he had learned in high school geography about cold fronts and warm fronts.
Before the cold front passes through, warm air masses first envelope the earth, and the temperature will rise.
After the warm air mass passes, there is a cold air mass pushing the warm air forward.
When the intersection of cold and warm air flows passes, there will be strong winds, rain and snow. When the cold air mass passes behind, the sky will clear up, but the temperature will drop a lot and it will be extremely cold. When encountering some extreme weather, a cold wave can form.
But be sure not to let a cold front pass through.
After thinking about the knowledge that he could no longer remember clearly for a while, Han Cheng thought to himself.
It was a trivial matter to delay spring plowing for a few days. What worried him most was the outgoing trade team.
When a cold front passes through, they may suffer a lot.
And judging from the rising temperature today, this warm air flow is bound to be quite large, and the cold air flow that can push such a warm air flow away will naturally not be much smaller.
After the weather gets warmer, a cold spring suddenly comes, which is really a scam.
With these things in mind, the first thing Han Cheng did when he woke up the next day was to feel the temperature.
The temperature hasn't changed much from yesterday, it's still very warm.
Could it be that I thought wrongly?
After Han Cheng stood here and felt it for a while, he muttered to himself.
It would be better if I thought wrongly, then I would suffer less.
Picking up the little pea when he woke up, and after teasing him for a while, Han Cheng carried him out of the room.
The ground is a bit soft and there was basically no ice last night.
I carried the little guy and walked to the cave used as a canteen, where the hard-working Huo Er was lighting a fire.
When the weather is cold, sitting in front of the stove and lighting a fire is a more attractive thing.
If you can bury two sweet potatoes in the fire, or put a piece of home-steamed and cooled steamed bun on a stick, then lighting the fire will become more attractive.
But this morning is an exception. In addition to Huo Er lighting a fire, Shitou is also squatting next to another firewood stove not far away.
What is this guy doing here making a fire today?
What's cooking in the vat?
Han Cheng held Little Pea in his arms and walked over with doubts. He turned to one side and let Little Pea aside. He grabbed the lid of the pot with his other hand and opened it with force.
After the white mist rose, the scene inside came into Han Cheng's eyes.
Bark?
Han Cheng's eyes widened.
What is cooked in this stone-burning stove is not food, but tree bark.
What is this guy doing boiling bark? Could it be that he wants to drink a bowl of bark soup in the morning if he wants to remember the bitterness and sweetness?
Han Cheng looked confused.
It was only after I saw that the bark cooked inside was the peeled off outer layer that I suddenly became enlightened.
It turns out this guy was tinkering with making paper.
But when making paper, do you need to boil the retted bark with water?
Han Cheng really doesn't know this, but it's always good to be brave enough to try new methods.
Because many new things are tried again and again.
Moreover, Han Cheng really didn't know much about papermaking. The papermaking process he had worked out before was very crude, and there was huge room for improvement.
Putting the lid back on, Han Cheng began to talk to Shitou about papermaking.
After studying this for several months, compared to the extremely difficult Feitian, the stone is on paper, and I really gained a lot of insights.
He felt that the paper made before was too thick and too hard. On the one hand, too much pulp was made during papermaking, and on the other hand, the pulp itself was too hard and too rough.
So he began to think of ways to make paper pulp softer.
After trying several methods, Shi Tou came up with the method of 'cooking'.
Because foods such as hard-to-bite raw meat and hard and chewy soybeans will become soft after being cooked in a large vat and water, so Shitou wanted to try this.
After listening to what Shi Shi said, Han Cheng couldn't help but nodded, feeling that it made sense. It seemed that it was wise to leave this matter to Shi Shi.
I was afraid that the bark would not be cooked properly, so I cooked it with stones for a long time.
It wasn't until breakfast was ready and everyone had had breakfast for a while that the stone ceased to fire.
After simmering for a while with the lid on, the lid was opened and the bark inside was taken out.
After soaking in warm water for a while, put it on the cutting board and cut it finely with a copper knife.
After cutting it, put it into the stone mortar and started pounding it. Han Cheng followed and watched the excitement, wanting to see if it could be done this time.
