Yang Yi brought a large number of books, but what he took out now is only a very small part.
In addition to proper screening, it is also because they also have a shelf life. If a suitable inheritance method is not found, the more you take out, the more you will lose in the future.
Therefore, Yang Yi could only take out the necessary books, and lay more quietly in the space.
The inheritance and dissemination of civilization cannot be separated from paper.
If you want to set up a school and let more people learn knowledge quickly, paper is essential.
Paper is one of the four great inventions in ancient China. It is a great invention for human beings all over the world, and its significance is very far-reaching.
If Yang Yi wanted to pass on the civilization he brought, he had to make paper.
Whether it is bamboo slips or parchment, there is no substitute for paper, which will limit the popularization of science among the people.
After Yang Yi was busy with the basic construction of materials, he began to start making paper to achieve a virtuous circle.
Sharpening knives does not miss woodcutters, papermaking, and learning knowledge are all time-consuming, but for those who are still struggling with food and clothing, it seems that it is not so urgent.
In fact, this is not the case, and cultivating talents is always the most important thing.
Yang Yi decided to use the ancient method of papermaking, which is inefficient but easy to implement at the beginning.
The ancient method of papermaking mainly uses bark, which is very easy to grow, and after the bark is scraped off, new bark can grow next year.
If it is an old tree, you only need to cut it down and bury it with soil. New branches will grow next year, and the bark will be even better.
Found in many parts of the world, it is very suitable for making paper.
Yang Yi had already asked members of the gathering team, hunting team, and logging team to pay attention to whether there were such trees.
Fortunately, there are also many mulberry trees in this world, and there is not much difference from the region.
The best time to strip the mulberry tree is in late spring and early summer. According to Jiao and Hei Lie's description, Yang Yi probably guessed that he should arrive here in early spring.
Now it is the season of late spring and early summer, which is suitable for making paper.
When Yang Yi was rummaging through books and researching how to make artificial paper, members of the collection team brought Yang Yi a food that surprised him—bamboo shoots.
Yang Yi has always encouraged everyone to collect fresh plants, and asked Qing to lead a special research team to perceive each plant and understand their habits.
We should not only focus on the crops brought by Yang Yi, but also pay attention to the native plants.
He believes that there are many native plants that are absolutely no worse than the ones he brought, but artificial planting requires some effort.
For example, the ground fruit picked before is a very good staple food, and it is also grown in the tribe now.
After this period of research, Qing said that the yield of this kind of ground fruit is not inferior to that of sweet potatoes and potatoes, and its taste is also very good, with a strong sense of satiety.
The most important thing is that it is also very rotten, just like sweet potatoes, it can take root and sprout and grow fruit by inserting its branches into the soil.
It is a native crop in this world, and it is more stable than Yang Yi.
Therefore, the current task of the collection team is not only to collect fruits and provide food for the tribe, but also to obtain more fresh plants for research by the tribe.
Especially now that the tribe's vegetables have begun to mature day by day, the leafy vegetables are completely enough for the tribe's consumption, and the task of the collection team has been greatly reduced.
Now the collection team has less than half of the previous staff, but most of them are excellent talents who know more about plants.
As long as they find fresh plants, they will bring them back to the tribe, name them if they don't know them, and gradually improve their information.
And it is made into a specimen, which is convenient for everyone to recognize in the wild in the future.
There will also be a very large room in the temple dedicated to the exhibition of these specimens, so that more people can get to know them more efficiently, instead of just relying on word of mouth.
Under this premise, as soon as the bamboo shoots were found, they were brought back and handed over to Qing, who was in charge.
As soon as Qing saw the bamboo shoots, he immediately found Yang Yi, and put the huge bamboo shoots in front of him.
"This is a bamboo shoot?! Where did I find it!"
Bamboo is widely used in daily life, such as the most common bamboo mats, bamboo baskets, etc. Bamboo shoots are edible and taste quite good.
And its growth rate is much faster than that of ordinary trees, so it is a very good raw material.
The person in charge of the collection team replied:
"Going east two days away from here, there is a body of water surrounded by these plants."
It is very difficult for the gathering team to obtain food just like the hunting team.
If the nearby food is collected almost the same, it will go to a farther place, which means that it will face more dangers.
The large number of people in the tribe will also bring greater pressure. In fact, the two-day journey is not very far. In the words of the people here, it is just a walk.
"Qing, you find the most outstanding plant talent talent, I am going to let him go there with the collection team, dig out the bamboo shoots and bamboos by their roots, and plant them in the tribe!"
"Leave this matter to me, it is most suitable for me to transplant."
Qing's talent is the strongest, and she is also a fighter. She knows how to do this kind of thing better than those who have just awakened their talent.
Yang Yi nodded. Although bamboo is easier to transplant, it is safest to let the most professional people do these things.
"These bamboo shoots are really big. Are all the bamboos there that big?"
The bamboo shoots brought back by the collection team were as thick as a bucket, and the inside was very tender after peeling off the shell. Yang Yi broke a little and put it in his mouth.
Very good, not bitter bamboo shoots.
It doesn't matter even if it is bitter bamboo shoots, it is still very delicious after processing.
"There are also small ones. I just took the biggest ones. Some bamboos are only as thick as a child's wrist, but many are as big as the mouth of a bowl. The thickest bamboo is dark purple. There are not many of them. Most of them are It’s green. We tried to cut it and it’s very hard and much heavier than normal bamboo.”
"You brought it back?"
"Yes, it's just outside."
Yang Yi went over to look at the purple bamboo, and said that the purple was already close to black.
The purple bamboo is sawn to a length of about two meters, and there are only two bamboo joints, each of which can be about one meter long.
Yang Yi tried to lift the bamboo. Fortunately, although it was much heavier than ordinary bamboo, it was not particularly exaggerated.
"This kind of bamboo can still grow in water." Yue said.
Yang Yi recalled for a while, it seems that the bamboo on the earth only grows near the water, not in the water
No matter what, Yang Yi was very happy that the huge purple bamboo could grow into the water.
This means that it has good water resistance and is not easily corroded by water. And it's so thick and not so bulky, it's very suitable as a bucket!
Yang Yi has been thinking about how to make buckets. At present, it is too extravagant to make buckets with metal, and it is very difficult to make buckets with wood. It is still difficult to achieve watertightness with the current technology.
Most of the metal or plastic buckets he brought are used in the tribe now, and almost all of his stocks are left in the space, leaving only a few as souvenirs.
Wooden buckets can also be crafted now, but in order to improve efficiency, I still use the lighter buckets he brought.
Now with this purple bamboo, the problem of heavy draft of wooden buckets can be solved very well, which is much easier than making metal buckets, wooden buckets, etc.
All it takes is chopping, piercing, and tying, and a bucket can do it.
And you can just open a small hole, fill it with water and plug it up, and you can pick several buckets at a time, which is convenient for strong men to carry water.
It can also be used to hold a lot of things, which is very practical.
It is necessary to plant a large bamboo forest in the tribe, which will bring great convenience to life.
Plus, bamboo can also be used to make paper!
The mulberry tree does not grow in sheets like bamboo, and its growth rate is not as fast as bamboo. Although it is also a very good papermaking material, the bark is relatively easy to obtain, but having bamboo papermaking at the same time can also ensure the supply of raw materials.
Bamboo also has its own shortcomings in papermaking, that is, the first step of soaking, which is also called "finishing" in "Tiangong Kaiwu", it takes too long, basically a hundred days away.
After the bark is dried in the sun, it only needs to be soaked for seven or eight days.
Papermaking is a very tedious and skillful craft, especially if you want to make high-quality paper, the requirements are higher.
Yang Yi called Lai Jiao and asked her to arrange ten people to study first.
"Have we finally started making paper!"
Jiao was very excited and had a great interest in papermaking.
She has been very anxious about how to pass on the books brought by the gods. Using the way of drawing pictures in the cave before is obviously not in line with reality.
Not to mention that there are no caves in their tribe, so many books and caves are too difficult to record.
As for making paper, she had also thought about it, but she felt that it was definitely not a simple matter, so it was not easy for Jiao to urge Yang Yi.
The tribe has too many things to do now, and she firmly believes that the envoy must remember all these things, but it has not reached that stage yet.
Although Yang Yi will inevitably make mistakes during the planning process, but the general direction is very rhythmic, pushing one step at a time.
Therefore, Jiao and the rest of the tribe trusted Yang Yi very much.
Starting to make paper now, Jiao's long-worried heart finally settled down.
"God assures you that I will place the brightest man in the tribe."
Jiao is well aware of the importance of paper, which is an important item for the inheritance of wisdom and the long-term development of the tribe.
For Jiao, he was also worried that this envoy, who came from nowhere, might leave again at an unknown time.
At that time, the things he brought, as he said, disappeared one by one.
Especially now that the tribe's items are starting to break down, she is even more worried about this happening.
This kind of anxiety actually exists in the entire tribe, and everyone shares this cognition.
So the feelings for the things they created are different from those brought by the envoys. The former makes them feel at ease, while the latter makes them feel lucky.
Luck doesn't come often, and they keep that in mind.
Having such a consciousness is also the result of the joint efforts of Hei Lie and Jiao.
One uses strength to guide, while the other mentally brainwashes.
"You don't need to pick someone who is particularly smart. Making paper is not difficult, as long as you are willing to use your brain."
There are still a small number of top intelligent people, and most of them are ordinary people.
Papermaking is very important, but there is no need to put all top talents here.
According to Yang Yi's instructions, Jiao found ten people who were ingenious and good at studying and sent them to him.
These ten people are all very young, only one or two are relatively older, they are very stable and careful, and like to study.
In the papermaking process, it is necessary to add paper syrup made from fir roots, glutinous leaves and other plants, which makes it easier to form paper and separate it from other paper.
The specific formula changes according to different seasons and environments. In some ancient paper-making villages, the formula ratio of each household is different, and it is a secret that they do not disclose.
Although the books Yang Yi bought in the mall have detailed records, they need to be allocated according to the specific situation when operating them.
There are only recipes in the books, but no principles. Therefore, if you want to make a more suitable one, you can only adjust it in practice.
"What I teach you is the most basic knowledge. If you want to make better paper and improve efficiency, you need to study and ponder it yourself. There will be books for you here, but like other skills, there is no A standard answer."
"My lord, we will not let you down!"
Yang Yi smiled and shook his head: "Your goal is not to let me down, but to make the tribe and your descendants proud of you."
The papermaking team became even more excited when they heard the words, with bright eyes and high fighting spirit.
They were chosen here, and they are very clear about their mission.
Their job is to pass on the knowledge of God!
People in the tribe today are very aware of the great power of knowledge.
The daily changes of the tribe are knowledge, and what is recorded in those books is also knowledge.
Hearing the envoys say that now made them even more excited and proud of being selected.
"Peel off the outer layers of the bark and use the second layer."
Yang Yi directed the ten people in the paper-making group to carry out the first step of making paper from bark.
For this step, the felling team specially sent a small team to peel the bark. Unless it is an old tree, it will not be used as firewood in the future.
This is also to ensure a continuous flow of materials in the future.
The members of the papermaking team are also very careful and fast, and pieces of second-layer bark are peeled off very quickly by them.
Yang Yi also tried it, and he was at least twice as slow as these people from the beginning. When they started to get acquainted with them, Yang Yi was so shocked that he gave up, and he still felt at ease as a teacher who could only talk.
After the second layer of bark has dried in the sun, they throw the bark into ditches that have been filled with water.
Papermaking requires a lot of water, and the process of soaking is several times.
Therefore, the paper mill was also built near the current ditch of the moat to facilitate the use of water.
At present, the paper mill is still a simple thatched mud house, but the rammed earth tile house is already under construction.
In addition to the bark being processed, a large number of bamboos transported from afar are also thrown in for soaking every day.
The tribe uses a lot of mud, and now there are enough ditches or ponds for soaking.
Because the original digging team was too efficient, some people were deliberately transferred away so that the speed of building the house could not keep up with the speed of dredging. Now they can show their talents.
After the bark is soaked, it is stirred and sized with a lime slurry made of lime.
"Lime slurry is corrosive, and you must be careful not to let it get in your eyes."
Yang Yi took out plastic gloves at this time to protect the hands of these people from being corroded. As for what to do in the future, he had to think of other ways.
Maybe you can consider using tung oil for waterproofing. Of course, it would be even better if you can find rubber trees, which are also important economic crops that make life more convenient.
At present, I am temporarily using the things bought in the mall. These problems can always be solved, but it is not as easy to use as rubber gloves.
When sizing, although everyone has been careful again and again, it is still difficult to avoid being tricked.
Several people's eyes were red, but their faces were still smiling, and they didn't care.
"What is this? I used to pick fruit in the jungle, and I accidentally got some plant juice into my eyes. It tastes like pepper into my eyes."
"My younger brother is in the collection team. He was assigned to pick peppers a few days ago, but he forgot to wash his hands and rubbed his eyes. Hahahaha, he suffered for several days, much worse than me."
"Hahaha, so that's your younger brother. I've heard that a fool was almost blinded by pepper."
"Yes, yes, it's my brother. He was scolded to death by the most beautiful Ding, and he said before that he wanted to have a child with Ding, but now he has to make a detour when he sees Ding."
"It's really scary for a hen to get angry! I'm not afraid of being cut by a knife, but I am afraid of a hen holding a needle."
"..."
Yang Yi simply didn't know how to describe his inner feelings. Is this too optimistic, or should he sympathize with that younger brother.
But thinking about these people who used to go out often and never come back, the death rate and injury rate are very high, but it just hurts the eyes for a while, it is really not a big deal.
As long as things are going well now, all suffering can be used as capital for chatting.
The former survivors of the Tusk tribe have long forgotten the dark days of those days.
At first, Yang Yi was worried that they would leave psychological trauma, and asked Jiao and Yu to pay more attention, but he didn't expect that after a few full meals, these people would all look like normal people.
It can be said that the heart is very big, and there is no such thing as depression and other mental illnesses.
As long as everyone has a bite to eat, they can be happy all day long. No matter how terrible things are, you can still dance and sing heartlessly.
After the soaked bark is starched, it is put into the water pool below which can be heated, and boiled for about eight days to completely boil them.
Because of this, Yang Yi also considered whether to put the paper mill on the side of the pottery group, so that it would be more convenient to obtain firewood.
Black Hunter believes that papermaking has a different meaning, and it requires many pools to soak bark and bamboo, so it is more appropriate to stay in the tribe.
Now the carpentry team has built the first batch of wooden wheels. With them, more people can transport firewood, but it is still enough to supply a paper mill.
After the bark is boiled, it needs to be rinsed in the pond, soaked with firewood ash water, placed in a pot, covered with a thick layer of plant ash, and then moved to another bucket after boiling. , Rinse with plant ash water.
In this way, after the plant fibers are completely extracted, they are put into stone troughs and pounded into mud. The finer and more rotten, the thinner and finer the paper can be produced.
Yang Yi had asked someone to make a stampede-style pound before, but it was originally used for pounding rice.
Just like a seesaw, using the principle of leverage to pound rice is relatively less labor-intensive than using wooden sticks.
"When you master these steps and actually make paper, you will let stronger people take up this job." Yang Yi explained.
This can also be considered a laborious task, and the people present here are relatively good in mind, but relatively weak in physical strength, so they are deliberately arranged here.
But it is said that their physical strength is weaker, and their speed of pounding the bark is still very fast.
"The next step is the most critical step to paper. I can only theory, and I have never operated it. You need to study it yourself."
After finding the bamboo, Yang Yi asked the best rattan craftsman to use bamboo to make paper curtains like bamboo mats.
The papermaking curtain has high requirements on craftsmanship, and it needs to be woven with extremely fine bamboo silk. When it is unfolded, there is a wooden frame below it.
At present, the papermaking curtains are all uniform in size, which is just suitable for ordinary people to open their arms and grasp the two ends.
It is a key item used to shape the pulp dissolved in clear water into paper, and the light and heavy swings affect the thickness of the paper.
How is the quality of the paper, this step is very critical.
Yang Yi also tried to do it, and found that he could only make thick and rough paper, and it was very laborious to cut it with a knife.
However, it was the first time to make paper by himself, and he was involved in every step, so he still kept it.
Others are different. It was a bit poor at the beginning, and when the first batch of pulp was all made into paper, it was obviously very thin and even.
After these papers are pressed dry and pasted on a specially built fire wall to dry, you will see sheets of white, delicate and thin paper.
"God's envoy, we did it!"
The people in the papermaking team were very excited, and the hard work of so many days finally saw results.
Every step took them a lot of effort. Although there are books as a guide, they still often make mistakes during the actual wiping operation.
And because the materials are slightly different, some book experience is not suitable for them, and they need to study and overcome.
But no matter how difficult the process was, they finally made paper that represents the progress of civilization!
Although the quality of the paper was far inferior to that brought by the angels, it was made by them themselves!
The people in the paper-making group seem to have seen that people in the tribe will use the paper they made in the future, and seeing these papers will record the precious knowledge brought by the envoys.
Although the hand feeling is not as good as the paper brought by the envoy, it can be used for writing, and the effect is very good, and the ink is not easy to see through.
And they are obviously more resilient than the paper brought by Yang Yi, and they are not easy to be torn.
Even the thinnest sheet is not easily soaked in water unless it is deliberately torn.
"You are very good!" Yang Yi praised without hesitation, "Soon, our tribe will have our own books!"
"Envoy, we will continue to work hard. We have mastered the skills under your leadership, and we will work hard on quality and speed in the future."
Although the people in the paper-making group were very excited, they wanted to show off the paper they made in front of everyone.
But at the same time, they are also very sober, what they are doing now is far from enough.
"You will be able to do it." Yang Yi is convinced of this, "We will need a lot of paper, and the specific requirements will be provided to you in the future. Your current task is not only to master how to make paper, but also to teach more people."
"Guaranteed to complete the task!"
