Stone Era: Restarting Civilization

the next day.

Pan Changgong called all the villagers of Ishigami village early in the morning to prepare for the relocation work.

There are two reasons why Ishigami Village lives on this small island in the lake. One is that there are superstitions circulating in the village.

The people of Ishigami Village also saw the stone statues of humans that can be seen everywhere on the island of Sunrise Land.

They couldn't explain this phenomenon, so they blamed the Land of the Rising Sun as a place where sinners were exiled, and they couldn't easily enter, otherwise they would also become stone statues.

But everyone just regards it as a myth Legendary, no one really believes it completely, otherwise, Amber would not have left the village and entered the Futu Mountain area hundreds of miles away to collect hot springs for her sister.

The real reason why they can't go out is that the production conditions are low, which leads to their slow population growth.

After hundreds of years of development, there are only dozens of people, and the small islands in the lake are enough for them to live in. There is no need to go to land.

Now that Pan Changgong has become the leader of this village, he must also start to improve the village so that they can become more qualified and excellent labor force to serve him.

The first is to get rid of the life of gathering and hunting, transform into an agricultural society, and increase the productivity of food.

People in Ishigami Village value their homeland and are reluctant to relocate, but Pan Changgong forced them to move out of the small island in the lake. This is the first step towards the farming era, because the soil on the small island in the lake is not suitable for farming.

For human beings, the control over nature is limited. Human beings cannot control sunlight, climate, or precipitation, but human beings can control the soil and fertilize the soil so that crops can grow better.

But in the final analysis, the role of chemical fertilizers is to make the soil nutrients last as long as possible, and it cannot change the soil itself.

No matter how fertilized the desert soil is, it is not easy to cultivate crops.

The soil in the Gangjing area is very fertile, but the capital area in the swamp is different.

Now that roads, vehicles, and communication tools have not yet been invented, it is unrealistic to manage and control two camps at the same time. The two camps must be merged into one.

Pan Changgong intends to relocate all the villagers from Ishigami Village to Gangjing Village.

Pan Changgong: "Has everyone assembled yet?"

Hei Yao was very familiar with the villagers, he looked over one by one, and then frowned: "My lord, there is one person missing, and Chromium hasn't come yet?"

"chromium?"

"Yes, Chromium is the sorcerer in our village, and he knows a lot of weird things."

"A sorcerer?" Pan Changgong thought of the situation when Amber once called his science a sorcery. Could it be that this guy named Chromium is also a scientist?

But looking at the ancient and primitive Ishigami village, Pan Changgong doesn't pay much attention to the scientific attainments of chromium.

"What kind of magic does Chromium know?" Pan Changgong asked casually.

Black Yao: "He, I saw that he once performed a sorcery called the Seven-color Flame Bridge, which can make the flames of the fire change into various colors."

"Huh? Yuanfang, what do you think?" Pan Changgong looked aside and asked Ishigami Senkuu.

Ishigami Senkuu raised the corner of his mouth and showed a pretentious smile: "Interesting, really interesting! This person named Chromium should have mastered some very simple knowledge of chemical reactions by himself. Changing the color of flames is also very simple. Put salt, copper, sulfur Just throw it in, and who is Yuan Fang?"

Pan Changgong didn't answer what Ishigami Senkuu said, and continued to ask Obsidian, "Where did Chromium go?"

"Curry, that guy is probably Curry in his treehouse." Ginro shouted loudly, looking at Pan Changgong flatteringly, wanting to show himself in front of the new leader.

"Treehouse warehouse?"

A group of people came to a dense forest clearing outside the village, and saw a small treehouse warehouse built in the middle of the clearing, which was located very high and required ladders, and there was a banging sound coming from inside.

"Hey, Chromium, what are you doing? Hurry up and get ready, we're leaving." Obsidian yelled.

After hearing Hei Yao's yell, the movement inside the tree house stopped immediately, and then, a short-haired boy with Brown hair with a white rope tied on his head poked his head out from the door, it was Chromium.

"My lord, Mr. Black Yao, I have a lot of things to bring, please give me a little more time."

After speaking, Chromium retracted her head to the side of Curry and continued to tinker.

"This guy is messing around with those junk again. It's simply wasting our precious time. I'll go and drag that guy out."

After finishing speaking, Hei Yao was about to climb up the ladder to catch people.

Ishigami Senkuu stood up at this time: "Wait, Master Obsidian, let me come."

After Ishigami Senkuu climbed up the warehouse, seeing the large amount of various ores on the Curry of the warehouse, the pupils of his eyes suddenly contracted.

He can see at a glance that there are many kinds of ores on the curry, some of which are quite precious. With his science and technology, it is estimated that he can make a lot of useful things.

This guy named Chromium is really a good material to make, Ishigami Senkuu thought so.

After Ishigami Senkuu came down from the tree house, he came to Pan Changgong's side and reported the situation inside the tree house truthfully.

Pan Changgong had the same idea as Ishigami Senkuu after learning that Chromium collected a lot of useful ores.

To the Common people, these ores are indeed broken stones, but to people like myself who have mastered science and technology, they may be useful if they keep them.

Pan Changgong immediately ordered some young adults in Ishigami Village to go to the treehouse warehouse to help Chromium carry his ores.

Everyone in Ishigami Village couldn't understand why their new leader was interested in these broken stones, but since it was an order, they could only obey.

Chromium seemed very moved, but when he suddenly thought of his sweetheart Liuli, that feeling disappeared again.

There are many children and old people in the villagers of Ishigami Village, and their movement speed is very slow, so it took Pan Changgong and his party a day and a half to reach the destination.

The villagers of Gangjing Village were very surprised to see their Lord Pan bring dozens of newcomers of mixed race.

Judging from the facial features, mixed-race people are indeed more beautiful. In Ishigami village, except for a few people, children who have not yet grown up, and old people, most people are considered handsome and beautiful.

When the people of Ishigami entered the tall fence and saw what the camp really looked like, they were not just surprised, but horrified.

In Gangjing Village, there are several neat brick houses and a large grid-shaped farmland, on which are planted many plants that they have never seen before. The villagers are all women, and the clothes on their bodies are unknown. What material is it made of.

This kind of material, Ishigami villagers saw that the current clothes on Pan Changgong were the same, more exquisite than them, but at first, the villagers of Ishigami village thought that Pan Changgong was the leader of a village, so they wore more exquisite clothes.

But now it seems that all the villagers in Shizuoka Village wear better clothes than those in Ishigami Village, and I don’t know what material they are made of.

There are also a lot of weird tools piled up on the side, everything is so fresh, it's like entering another world.

Pan Changgong temporarily arranged the villagers of Ishigami Village in Gangjing Village, but for the time being, the scale of Gangjing Village cannot continue to expand, because there is only so much high-quality soil near the village.

Dozens of people in Ishigami Village need to make additional arrangements to choose a nearby area with high-quality soil for them to live and farm there.

Both Magma and Mantle were handcuffed, and they were driven into the village's blacksmith shop to forge iron with Shishio Tsukasa.

Grandpa Fossil and Chromium, who were taken care of by Pan Changgong, also stayed in Gang Shizumura, allowing them to cooperate with themselves and Ishigami Senkuu to make some utensils.

Needless to say, Miko Liuli stayed with Chiba Xihe to manage the subordinates of Gang Shizumura for her.

Pan Changgong set off immediately, ready to explore the qualified soil nearby.

Soil is actually the reaction product of humus after the crustal rocks are eroded by wind and water.

The greater the degree of erosion, the better it is relatively suddenly. According to the degree of erosion, the nature of the soil can be divided into gravel, sand, and clay.

The most suitable soil composition ratio for farming is: 40% sand, 40% fine sand and 20% clay, that is, the sand content of the soil exceeds 2/3.

The soil with this compositional structure is suitable for most of the crops invented by humans, such as barley, wheat, soybeans, potatoes, rapeseed and the like.

However, some crops are more special, and the soil they pursue is different.

For example, oats like wetter soil. Soil with a sand content of more than 2/3 has good drainage performance, which does not meet the needs of oats. If you want to plant oats, you need to plant them in soil with a clay content of more than 1/3. middle.

Rye likes poor soil with a sand content of more than 80%.

Wheat and rice are delicious where rye and oats are. Pan Changgong only kept rye and oats. The staple food for him and his men is still wheat and rice, and they only choose rye under special circumstances. and oatmeal.

How to judge whether the soil is qualified or not, the composition of the soil cannot be seen at a glance, so a small observation experiment must be done.

Pan Changgong came to a few places near Gangjing Village where the terrain is relatively flat and wide, and close to the river. Such places are suitable for farming and living.

Pan Changgong found six such places, all of which are very close to each other, and the farthest one is only ten minutes away from Gangjing Village.

Pan Changgong took the soil from these six places and returned to Gangjing Village.

First, some large impurities in the soil, such as large stones, and plant stems and leaves are all picked out.

Then put the soil taken from the six areas into six transparent beakers, and fill the beakers with soil to a height of 1/3.

The next step is to pour water into the beaker until the entire beaker is filled.

Finally, cover each beaker and shake vigorously to disperse and mix the soil and water inside until the six beakers turn into a cloudy muddy soup.

In this way, even if it was over, Pan Changgong put the beakers flat on the table and left. The results of the experiment will be seen tomorrow.

Immediately afterwards, Pan Changgong gathered people again to make some clothes, so that the villagers in Ishigami Village could also change into new clothes.

On the way to Gang Jing, Pan Changgong chatted with Liuli and Hei Yao father and daughter and learned that the life of the villagers in Ishigami Village is not very good. It is true that their population is not only low in productivity, but also many people cannot resist it. In the severe winter, there will always be several people who are frozen to death every year, especially children and the elderly.

The clothes of your villagers in Ishigami Village are all thin layers of coarse linen, or better yet, animal fur stripped from an animal, which is very simple and primitive.

They didn't know that if they were filled with cotton, they could be used to keep warm.

Therefore, the villagers of Ishigami Village, every year when winter comes, store food in advance, hide at home, hibernate like those hibernating animals, and dare not go out.

Although clothing is very common, it is also an important tool for human progress. Compared with many beasts of nature, the human Constitution is very thin. Generally speaking, I am an exception.

Most human constitutions are only suitable for living in low-latitude temperate regions. If you want to enter high latitudes, if you don’t have clothes to keep out the cold, people will freeze to death.

After the invention of clothes, human beings can arbitrarily enter the world with different climates, allowing human civilization to develop.

There are many kinds of materials for the clothes of modern civilization, but they were all produced in the past 100 years. Before 100 years, human beings did not invent fiber nylon. Such high molecular compounds, more than 100 years ago, human beings still wore clothes from animals and Plant material clothes.

The same is true for Pan Changgong. He has no conditions to produce fiber nylon, but the source of animals and plants is good enough, and he has opened up a piece of land dedicated to growing cotton.

There are also a few sheep raised, and the sheep's wool is very warm.

Clothes are made from plant fibers such as hemp, jute, flax, sisal, the stems of these plants, leaves of agave, yucca, and cotton.

Animal fibers for making clothes are even more common, and any long-haired mammal can be used. However, from the perspective of practicality, mink and fox velvet, which are very precious even in modern times, must not be popularized.

The source of Pan Changgong is only wool.

In fact, the silk spun from silk can also be made into clothes, that is, precious silk, but unfortunately, Pan Changgong does not know how to make it, because the actual production is very complicated. Without the Internet, he did not find how to make it in bookstores. Tutorial book for making silk.

Since silk is not necessary, Pan Changgong did not tinker with it.

Now, the most urgent need of the villagers in Ishigami Village is clothes that can keep out the cold, and winter is coming soon.

The Pan Changgong Warehouse Curry happens to store a lot of cotton and wool.

These cottons and wools are processed, and cotton is easier to handle, and it can be dried directly after picking.

Wool is more complicated. Because it is animal fiber, it contains a lot of oil. It needs to be fully washed in water and then combed to make it neat.

Finally, like cotton, it enters the weaving step. It is best to have a weaving machine for this step. Fiber, let them become long and tough threads, but if you use your hands, it is too time-consuming, and if the population is large, the efficiency of making clothes with primitive weaving techniques is too low, and everyone must not participate in making their own clothes.

Pan Changgong hadn't made a loom yet, so it wasn't necessary before, but it will be necessary with the increase of population.

The structure of the textile machine is very complicated. Although Pan Changgong knows it, it still takes a lot of effort to make it. He is going to hand over this task to Ishigami Senkuu.

Pan Changgong arranged for a few men who had seen how he made clothes, and asked them to bring cotton and wool, and then let those who can make clothes in Ishigami village go to watch and learn, so that they can make enough warm clothes as soon as possible.

After the villagers of Ishigami Village entered the village, their three views were refreshed time and time again. The waterwheel next to the stream behind the village, and the many domestic animals they had never seen in captivity made them feel a little strange. understand.

When it was time for dinner in the evening, the villagers of Ishigami Village ate the delicious food they had never tasted before, and cried while eating.

On the second day, Pan Changgong came to check the soil in the six beakers. The soil suspension in the beakers that had turned into muddy soup yesterday had re-settled after standing still.

And it becomes clear that the particles of different sizes in the soil are deposited in different orders.

The bottom of the beaker is naturally coarse sand in the soil, the middle is fine sand, and the top is clay particles with the smallest quality.

Through the transparent beaker, one can see the proportion of different substances in the soil inside the beaker at a glance.

Among the six beakers, three were qualified, and Pan Changgong chose one of the areas closest to Gangjing Village.

In this way, the resettlement site for the villagers of Ishigami Village was selected.
