Chapter 606 Convergence of Cold and Warm Air
When I got up the next day, the sun had already come out from the east.
Not very bright, her sallow face is comparable to the dreamy Han Cheng.
However, the temperature is quite high. Compared with yesterday, it has risen by at least seven or eight degrees.
By noon, it was already warm outside.
Some old people who were afraid of the cold came out of the room, squatted at the base of the wall, holding the soles of their shoes, basking in the sun.
Some strong people even took off their thick leather jackets.
Some women in the tribe are taking this opportunity to heat hot water to bathe the minors in the tribe.
Because of the relatively high temperature, there is no need to even go to the bathhouse.
At such a temperature, the surrounding snow is melting rapidly, and by ten o'clock at noon, it has become much thinner, and the covered withered grass has been exposed in some places.
According to this trend, it only takes three days at most, the snow will basically be completely cleared, and the spring plowing in the tribe can start.
In the tribe, Shito picked up a stone pen a little excitedly, drew a line on the simple calendar he made, and engraved some words on the bottom at the same time.
Of course he was excited. In this winter, he thought of a way to 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 warm up, it won't be long before he can start testing his ideas and making better paper.
It wasn't just the Qingque tribe who were excited by the warming weather, all the tribes around them who felt the warmth became excited.
The food they have saved is running out, and some of them are even about to run out. Now that the weather is starting to get warmer, this is undoubtedly excellent news for them.
Some tribes who lacked food, at this time, some people took advantage of this opportunity to go out to search for food.
In winter, sometimes some birds and small animals will freeze and starve to death.
After the snow melts, these snow-covered things will be exposed,
Be food for the hungry, people.
Han Cheng, who was happy in the sun for a while, frowned, because he suddenly remembered what he learned in high school geography, about cold fronts and warm fronts.
Before the cold front passes, warm air masses cover the earth first, and the temperature will rise.
After the warm air mass passes, it is the cold air mass that pushes the heating air.
When the confluence of cold and warm air flows across the border, there will be strong winds, rain and snow. When the cold air mass behind passes through the border, the sky will clear up, but the temperature will drop a lot.
But don't let the cold front cross the border.
After recalling the knowledge that he didn't remember very clearly for a while, Han Cheng thought so in his heart.
Delaying spring plowing for a few days is a trivial matter, and what worries him most is the trade team going out.
When a cold front crosses the border, they can't say they will suffer a lot.
And judging from today's rise in temperature, this group of warm air is bound to be not small, and the cold air that can push such a warm air will naturally not be too small.
After the weather warms up, it will be a real scam if there is a sudden cold spring.
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 has not changed much from yesterday, it is still very warm.
Could it be that I was thinking wrong?
After standing here feeling for a while, Han Cheng muttered to himself.
It would be better if I was wrong, so that I would suffer less.
Picking up the sleeping little pea and teasing him a lot, Han Cheng carried him out of the room.
The ground is a bit soft, and it basically didn't freeze much last night.
He carried the little guy to the cave used as a cafeteria, where the industrious 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 use a stick to put on a piece of steamed steamed bread that has been cooled at home, then the fire will become more attractive.
But this morning was an exception. In addition to Huo Er who was lighting the fire, there was another firewood stove not far away, and Shi Shi was also squatting there to make a fire.
What is this guy doing here today?
What's cooking in the crock?
Holding Xiaowandou in his arms, Han Cheng walked over suspiciously, turned his body to one side, moved Xiaowandou aside, grabbed the lid of the pot with the other hand, and lifted it with force.
After the white mist rose, the scene inside came into Han Cheng's eyes.
bark?
Han Cheng's eyes widened.
Instead of food, the stone-burning stove cooks bark.
Guy, what are you cooking the bark for? Do you want to drink a bowl of bark soup in the morning to recall bitterness and sweetness?
Han Cheng looked bewildered.
It was only after seeing that the bark boiled inside was the peeled-off outer layer that he suddenly realized.
It turned out that this guy was fiddling with papermaking.
But when making paper, do you need to retting the bark and then boil it in water?
Han Cheng really doesn't know about this, but it's 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. The papermaking process he created before is very simple and has great room for improvement.
Putting the lid back on, Han Cheng began to talk to Stone, talking about papermaking.
After several months of research on this, compared to the extremely difficult Feitian, the stone is on paper, and I really have a lot of insights.
He felt that the paper produced before was too thick and hard. On the one hand, there was too much pulp when making paper, and on the other hand, the pulp itself was too hard and too rough.
So he started figuring out how to soften the pulp.
After trying several methods, Stone came up with the method of 'cooking'.
Because hard-to-bite raw meat and hard-toothed soybeans will become soft after being cooked in a large tank and water, so Stone wants to try this.
After hearing what Shi Shi said, Han Cheng couldn't help but nodded, thinking it made sense, it seemed that it was wise to entrust this matter to Shi Shi.
Fearing that the bark would not be cooked properly, the stones were boiled for a long time.
It wasn't until breakfast was ready and everyone had eaten breakfast for a while that the stone stopped the fire.
After covering the lid and simmering for a while, the lid of the pot was lifted to get out the bark inside.
After soaking in warm water for a while, put it on a cutting board and cut it finely with a copper knife.
After cutting it, put it into the stone mortar and start pounding it once and for all. Han Cheng followed to watch the excitement, wanting to see if it could be done this time.
