Mountains and seas can be flat

Fang Zheng woke up from the bed, and what he saw was a small and sturdy house structure.The gray-black wall makes people unable to see the material, but it is Fang Zheng's proud work.

This is "cement".It is not the cement of the modern industrialization of later generations. It is the most primitive "cement" that uses a large amount of ready-made volcanic ash and stone powder, adds water, heats and stirs, and then dries.Its hardness is close to that of stone, it is rainproof and moisture-proof, and it is strong and strong.

Fang Zheng sat up. He was sleeping on a wooden bed.There are many layers of straw and leather on it, so I can sleep comfortably.

Fang Zheng picked up a distorted clay bowl on the table and sighed.No matter how many times it is burned, it will always look crooked.That's about to be the next problem he'll tackle.

It has been three years since he escaped from the "Daqinglong" crypt of the Sanmiao people.

During this period, Fang Zheng solved some problems, but there were more problems in front of him.

Fang Zheng got up and pushed open the door, the sky was not bright yet, and the mist filled the air.There are dozens of gray-black huts made of volcanic ash and stone powder, scattered around in twos and threes.These sturdy stone-mud houses were the first problem that Fang Zheng solved.

At that time, Fang Zheng led a group of old, weak, sick and disabled, followed the direction of the end of the volcanic magma flow, and found the depth of this closed small valley.The valley is like a long and narrow pocket. There are countless pinnacle barriers along the way, and there are steep rivers. The magma only covers the first few layers of barriers, and it is blocked and cannot flow in. It can be said that if the volcano erupts again in the future, this bag-shaped The valley is still safe.

Volcanic magma sealed the entrance of the valley, and ordinary people and giant beasts could not enter at all. Fang Zheng and the others entered and exited through a hidden passage, and they have never leaked traces in the past three years.

At the beginning, Fang Zheng took them to chop wood and build the simplest "branch house".The beech that can be seen everywhere on the mountain is used. The beech is light and easy to build. It can be surrounded by a fence in two days and covered with a handful of thatch to make a transitional residence.Although beech is easy to find and cut, it is a low-quality wood that is not resistant to moisture and insects, and it will die within a few months.

At the beginning, Fang Zheng tended to find good wood to build a house, but to meet the requirements of wood, not to mention Nanshu, at least it should be burly elm and maple.Although the nearby natural conditions are good, there are not many tree species that meet the requirements.Fang Zheng took a lot of effort to find a maple wood. According to this density, it would take more than ten kilometers to find all the wood needed for a house, and the stone ax could not cut that kind of solid wood at all.

Planting trees is not the answer, he can't wait ten or eight years.

Fang Zheng found another way. He took a fancy to the large amount of volcanic ash accumulated at the mouth of the valley.They are all left by the magma flowing out in those years.

The main component of volcanic ash is calcium carbonate, which is also one of the materials for making cement in later generations.The main purpose of cement is to bind sand and stone together.Fang Zheng experimented, built a mud pool on the ground, shoveled the volcanic ash into it with a stone plow, the oldest tool shaped like a plow, and then added it to the cold stream.

The water in the mud pool was hot at first, and bubbles came out. After cooling down, the volcanic ash hardened even more, sticking the stones together.The stones here are mainly volcanic rocks with pores after solidification on the ground. It does not need to be laboriously excavated. It is an excellent strong and light building material.

Fang Zheng experimented a few more times, found out the best ratio of river water, volcanic ash, stones, and mud, and made the most primitive and crude "cement", which is of course different from modern cement.But they can be used to build a crooked wall, withstand the test of water, fire, bug gnawing and old monkey scratching, and start building a house.

It is not possible to build a duplex for the time being, but a single-storey bungalow is enough.

He built himself a huge one-story bungalow and told the rest of the tribe how.

The elders of the Youbi country brought the tribal women to build stone houses, and the thing used to stick the stones was "Bai Kui", another form of lime, given by the suzerain country.But after seeing Fang Zheng's series of operations, Elder Xuan Si was very surprised and said that the thing in the muddy water was like Bai Kui, and it was better than that.

Since Fang Zheng tidied up the old monkey - including not limited to a series of operations such as holding it and shaking its tail violently - it will obediently please Fang Zheng.For example, at this moment, it is holding a rattan bag with a few fresh chestnuts in it.Fang Zheng picked it up and peeled it to eat.The old monkey squeaked expectantly at the side, and when Fang Zheng felt comfortable eating, he fed it the peeled ones, rubbed the monkey head and let it go.The old monkey continued to run to collect in full swing.Fang Zheng seriously suspected that the old monkey had a flattering personality, no, monkey personality.

The staple foods collected are hazel, chestnut, pine nuts and hackberry seeds.The impact on the ecology after the volcanic eruption has not only benefited the area with building materials.After experiencing the baptism of high heat and ash, the soil became more fertile, and a new batch of edible ferns, fruit trees, low shrubs, and fungal spores developed more luxuriantly.As long as they wander around the edge of the stone peak for a day, they can collect a lot of natural food.

Fang Zheng does not want to regard collection as the main economic model.He walked out the door, and there was a piece of land in front of the house.This is the second problem that Fang Zheng is trying to solve.

There are crops on the land.Although there are only two simple types now, one is potato cornel and the other is wild rice.Yamwood is an ancient yam, one of the root plants abundant in the region, and it was also the staple food of the tribe in the past.When digging up the babies from the commune, they brought along a lot of yam vines.

Wild rice is Fang Zheng's feelings as a "modern man". He wandered around for a long time, and finally found a very small wild rice seed with only three spikes.In the first year of sowing, the seeds were not at the right depth, and the timing of watering was not right, so only three or four seeds grew out of a handful of grains.In the second year, Fang Zheng learned a lesson and got a little better, with seven or eight seedlings growing. However, Fang Zheng burned half of the seedlings to death with the "soil fertilizer" of manure and fish scales and shrimp shells. Ten years later, he will be able to use the rice he grows as his daily food.

Unintentionally planting willows and willows to make a shade, somehow a millet got mixed into the rice, Fang Zheng planted the rice in a mess, but the millet was a success story.At first, Fang Zheng only thought that there were a few dogtail grasses growing on the edge of the field, and he ignored them as they were far away.As a result, after it turned yellow in autumn, it actually produced big and plump millet. In the second year, Fang Zheng gathered the seeds of the dogtail grass into the field and left it alone. Thick grains of millet quietly spread to a quarter of the field, tall and dense, and the ears weighed five catties.It's also not enough to eat for a few days, but considering the density range, it's a pretty impressive result.So Fang Zheng began to plant a large number of millet seeds in the third year, and the current growth is gratifying.

Beech is used to surround Fangzheng's house. Since the house was built with volcanic ash, the abandoned branch house has been transformed into a livestock pen.There is a congress that keeps cattle and horned chickens as food reserves when there is nothing to hunt.The level of agriculture still does not require cattle, so Fang Zheng still hunted a cow and tied it in the shed to keep him company with the horned chicken.It's a pity that there are not so many lands that need to be "cultivated", because other people don't want to make a living from farming, otherwise Fang Zheng would still want to use wood to make plows.

The elders and women who escaped from the tribe respected Fang Zheng very much and lived a prosperous and stable life.For the time being, Fang Zheng is satisfied with this peaceful life.Although he himself comes from a modern agricultural civilization, he has a desire to farm that cannot be ignored in his genes.It is a pity that this era is ignorant and turbulent, and has not yet been able to move from a primitive society to a typical farming society.

For the time being, Fang Zheng just lives with them and has no desire to drive them, so he can't let them change the main economic model and explore and farm with him.

Agriculture and animal husbandry cannot become the mainstream of the Yubi tribe for the time being, and can only become a supplement to fishing, hunting and gathering activities.There is a small river near the camp, which flows into the big river outside the hidden road in the valley. The relatively wide watershed makes the aquatic products very rich, which is conducive to fishing.The tribe used to only use primitive tools such as fishhooks or harpoons. Recalling the aquatic tools of later generations, Fang Zheng designed a net pendant.The net is made of coarse hemp, and the net pendant is made of stone. You can catch several catties of fish in one batch, and you can pick algae and snails with bare hands.

As for the types of land collection, there are more types, in addition to conventional fruits, fungi, and plant roots, there are also things such as bird eggs, honey, and even insects.Most tribal women are unwilling to farm, and they cannot pick it every day.

Fang Zheng has lived here for three years, and the problem he most wants to concentrate on solving is copper.He still carried Zifeng's bronze sword, but Fang Zheng didn't know enough.What he faced were several large countries that were expanding with arms in the late primitive society and early slave civilization.He must practice martial arts well, become stronger, and create more things to protect himself.A set of bronze armor to protect the chest and abdomen is necessary.While he was tirelessly looking for copper mines, he had to face up to a problem: even if he found mines, copper would not be produced here.

Fang Zheng remembered that the copper-making method in "Warring States Policy" is a wet copper smelting method, which belongs to the replacement principle scientifically. The copper ore is soaked in acid, and then replaced with iron.But acid and iron are very difficult to deal with.The temperature of iron smelting and copper smelting is about the same.

The second is ordinary high-temperature copper smelting. The climate here is humid. If there is no blast furnace, it is impossible to heat up to the temperature required for copper smelting.But the blast furnace itself needs reinforced concrete or copper and iron to make, which has fallen into a dead circle.

The melting point of pure copper is about [-] degrees, and the melting point of miscellaneous copper is about [-] or [-] degrees.The calcination temperature of the best granite will be higher than this number, but the solid granite is buried deep in the ground, even if it is exposed to the ground, it cannot be mined, and only a white spot can only be chiseled.The main component of the volcanic rock that Fang Zheng picked up was calcium carbonate, and it also had many impurities. It was very heat-resistant and would break when burned.There is no way to craft a blast furnace out of stone.

Fang Zheng turned his thoughts to Tao again.Pottery is fired from clay and can withstand high temperatures of more than [-] degrees.However, there are no molds here, and roulette is the most commonly used for pottery making in later generations. Only a small number of people are still kneading with bare hands, which requires a high proportion of mud, which must be both pure and cohesive.Fang Zheng tried many times, but unlike cement, he could do it.Fang Zheng wanted to use it to withstand high temperatures, and it often shattered when burned.

If this problem is not resolved, Fang Zheng can only stay here and farm quietly.In fact, this place is not bad for the time being, Fang Zheng thought, it can almost be regarded as a small paradise.The location is hidden, the natural conditions are rich, the personnel composition is simple, there is no slavery, no war, no threat to life, and enough food, clothing, warmth and sleep every day.It almost gave Fang Zheng an illusion that even if he couldn't get out, it seemed good to live here for the rest of his life.

Probably this is the sense of worry.Fang Zheng thought to himself, when he first came here, he just wanted to try his best to survive, but after he survived, he began to think, is this place really safe forever?Fang Zheng couldn't guarantee it.

There is also an almost extravagant wish - this valley is surrounded by mountains, the horizon cannot be seen, and naturally the building tree cannot be seen. It seems that if you see a little more, you will be away from your father for a lifetime" Shanhai Daguo said, "Get closer, I have the illusion that my father has not left, and I am still chanting those documents in my ear...

Fang Zheng misses him so much.

Still have to find a way to make weapons.Fang Zheng secretly thought, if one day, whether the subjective conditions are ripe, or he is forced to leave this safe place... Then why would he protect himself?

So in addition to his daily work, Fang Zheng has to search for ores and "useful" "good things" nearby every few days.What he likes to look for most is the guts of snakes and snakes, and he also likes to capture the horns of rhinoceros, elk, antelope and other animals, all valuable things that can be eaten and can be used as weapons.

For the women of Belgium, these two years have been like a dream. They have lived the life they wanted, collecting, fishing, farming, weaving, and occasionally learning how to farm land with curiosity.There is no need to pay tribute to the suzerain, no need to undertake heavy and tiring work every day, and no need to be forced to become pregnant.

Most of the babies who were dug out survived, although in Fang Zheng's eyes, the boy babies who took the medicine were all stupid, like a group of piglets.In the past few years, he has been three or four years old, and he is crawling around on the field.Fang Zheng would also take the cub out when they climbed into the mud pit, and unceremoniously carried it to the river to rinse it all.After that, many little ghosts hurriedly crawled away when they saw Fang Zheng.

But the tribe also continues to have sharp demographic tensions.In fact, the month Fang Zheng had just settled down, elders from Biguo and a group of women who could talk to him came to talk to Fang Zheng with serious concerns.

They only look forward to Fang Zheng's leadership, but hope that Fang Zheng can truly become the "male leader" of this clan's blood, and sincerely tell Fang Zheng that all women belong to him.

Fang Zheng didn't agree, he didn't drive other people's preferences, let alone women.

But the tribe did not have any extra men.

Although the man still has a servant cow, but he has been tortured, which is too difficult for others.

Fang Zheng had a headache, and asked the two great elders, saying that you are also men, and even if you are a very old man, you can actually do that. If you want to borrow a seed, it is not good to digest it directly internally?Elder Mingye and Elder Xuansi hesitated for a long time before letting Fang Zheng know that the suzerain country eunuched them all.

Fang Zheng didn't want to be a tool for the tribe to provide sperm. Suppose the sex was reversed, and a strange woman wanted to provide reproductive services for a man of a primitive tribe, so he could intuitively understand how disgusting it was.But Fang Zheng also understood their development awareness and reproductive needs, so he suggested a compromise.

There are not many men in this land.There will always be people who are willing to sit back and enjoy the "blessings of all people".So in the past three years, many young single men who lost their way near the valley walked into the paradise, and since then, they have been "unforgettable".

In order to avoid leaking secrets, before "entertaining" these young single men, it is necessary to identify clearly that they are indeed men who cannot survive outside, have escaped, and accept the tribe's "pair marriage" lifestyle.Identifying them has become an important task for Fang Zheng.

In ancient times, before monogamous marriages existed, primitive tribes were the first to implement group marriages. As long as the seniority was the same, brothers and sisters could intercourse with each other, and no one had a fixed sexual partner.Later, in order not to reproduce dementia among close relatives, it evolved into that the same generation can form sexual partners with different people except brothers and sisters. Women have three to four sexual partners, and men can also have sex.The offspring follow the female line, and the status of women is slightly higher than that of men, which is one of the population characteristics of primitive matrilineal society.The pairing system is called "pairing marriage".

The tribe of Youbi country did not form this system naturally, because all the men in their tribe had been wiped out, and they were forced to form a small "matriarchal society". Men who "entertain" in must "enjoy" several women, whether voluntarily or not.These immigrant men do not need to engage in complex productive labor, but instead need to take care of the three or four-year-old children in the commune.

Without the concept of chastity and the desire to possess, it is impossible for tribal women to form a family economy alone to cope with the difficulties of life, and naturally there is no need to form a family structure of one man and one woman.The entire tribe still implements the communal family economy.

Basically, the men who survived the identification would not be able to live outside. Even if they had to fulfill the obligation of "enjoying" a few women here, their lives would be very satisfying.

"I picked up another seriously injured man outside today." Ji Liu came to the farmland and found Fang Zheng, who needed him to "identify".

Men who have been seriously injured outside have a high possibility of "staying".Several fugitive slaves from Badian Kingdom died outside and were brought back to life.Now he has become a loyal supporter of the commune.Work is called a positive and serious person, full of enthusiasm, and I am so happy that I can't find the north every day.After all, life here is much better than outside.

Ji Liu looked at Fang Zheng affectionately, she still did not give up, and did not join the "pair marriage" between other women and foreign men.After the daily weaving work, she has her own free time. Instead of thinking about the entertainment of the night like other women, she goes to pick the rare wild silk nearby.The number of wild silkworms is very small, and usually only a few can be picked a day.She saved up all of it, and when she had enough, she wove clothes for Fang Zheng.In the first year she wove a long white quilt, in the second year she wove a long "through head" gown, and in the third year she was still saving up to weave a curtain for Fang Zheng.In fact, although the robes woven by wild silkworms are precious, they are very fragile, do not keep warm, and are inconvenient to move around.Fang Zheng basically does not cover or wear.

Fang Zheng is thick-skinned and heartless.I have rejected her many times, but the other party still wants to come forward, so I will accept it if I should, and I will not promise if I accept it.Fang Zheng scoffed at this infatuation.He felt that he was betraying his feelings, but this kind of thing had no solution, and he didn't worry about it.

The conditions of this tribe are not enough to develop silk reeling, nor does it have the technology to domesticate silkworms. There are indeed wild silkworms nearby, but many women think it is too troublesome and not practical.The most common weaving is still grass and fur.

When Fang Zheng came to the commune, Ji Liu told him on the way that the man was found in the "Big Triangle".

Fang Zheng said "Oh" and thought of the sand table map in the room. The "big triangle" is the area where war slaves are most often found. No area of ​​attribution has been determined.

There are often many escaped slaves in this area, and it mainly depends on the person's own background to identify them.Every time they come to ask Fang Zheng for help.

The commune has taken on a new look.When the volcano erupted in the mountains, there was a lot of volcanic ash accumulated in the valley. The commune houses were especially huge, larger than the small courtyard built by Fang Zheng.There are separate storage and conservation halls, separated from the main meeting hall.The elders can put as much medicine as they want, and there is no need to hear the children's cries and smoky wormwood.

Maybe it's because people are in good spirits on happy occasions. In recent years, the two elders seem to have grown up against each other, and they have become a little younger.On the stone bed in front of them lay a badly wounded man.Seeing this scene, Fang Zheng seemed to have seen the scene where he was lying in the commune after being injured.

Both elders looked cautious, perhaps because the man was wearing a white robe.They are discussing how to deal with it.

It was a young man, lying flat, about the same height as Fang Zheng.The skin on the unfamiliar face was extremely pale and delicate.Under the plain silk robe is a plump body, his skin lacks blood, his lips are as pale as snow, and his hair is very long, draped all the way to the back of his shoulders.

Elder Ming Ye said that although the young man appeared to have no trauma on the surface, he was unconscious and vomiting blood, which may be due to internal injuries.And his bones are very strange, very large and very hard.

What's even more strange is that this boy is almost skinny, with almost no flesh under the skin, but the bones under his skin are larger than those of ordinary fleshy people.From the outside, it is even a little honest.

When Fang Zheng saw the sleeping face of this young man, he felt somewhat familiar.Obviously, I have never seen such a strange face before, but I always feel... as if I met it somewhere.

Yes, it is to attack.Vest x1
