The importance of the wall is even greater than the other three, and the amount of work is even larger, but there is no crisis for the tribe for the time being, and the fence can be used for the time being, and the wall will not be used for a short time, so it will be built last.

The original wooden rattan fence covers several miles around, two thousand zhang from east to west, four thousand zhang from north to south, just around the top of the cave where the tribe is located, and most of them are slopes and cliffs, and there is very little usable area.

After clearing the bushes on the hillside, eight platforms were sorted out, each with an area of more than ten zhang wide and twenty zhang long, one platform was used to build the council hall and the education school, and two platforms were used to build houses.

There are three empty platforms in the middle, which are expected to be reserved for future repairs, one platform has built a enclosure, and there is an empty platform below, and then there are some gentle slopes below, and ten acres of fertile land have been reclaimed, and no other vacant land remains.

Behind the cave hill, there are streams and mountain streams, there is no way to expand, the opposite of the stream is a mountain forest, the terrain is complex and steep, not easy to cultivate, if you want to develop planting, you can only reclaim the fields under the mountain.

At the foot of the mountain there is a slope, but outside the fence, close to the grassland below, overgrown with weeds and shrubs, lurking all kinds of evil opportunities, let the tribe go outside to cultivate, it is easy to get dangerous.

If you don't find a way to solve it, the cultivation industry will not be able to be carried out, and Yeyang's thought is to build a wall, ban the original fence, expand the territory of the territory, strengthen the defense of the tribe, and lay a solid foundation.

Since you want to repair it, you have to repair it well, build it big, at least it can be used for decades, save it from repairing it for a long time and then replace it, wasting manpower and material resources in vain, although it may be very difficult now, but the future will definitely be beautiful.

The plan of the wall was ten miles from east to west, and ten miles from north to south, and the front of the mountain was pushed directly through the barren meadows, pushed to the edge of the grassland, and behind the mountain also pushed over the creek, and pushed back some distance, to the place where the tribe cut wood.

To the south, he had to push through the sandy beach of the bamboo forest, and to the north near the limestone mine, and the area alone was ten miles in circumference, with a total length of 40,000 zhang of the city wall, and the amount of work was unprecedentedly huge, showing his ambition.

The city wall is expected to be five feet wide and three feet high, and the foundation is also made of stones, and the material of the wall is still Sanhe soil, but it will not be stacked with green bricks, and if it is made of green bricks, the number required is too much.

Unless ten more brick kilns are built, refining day and night, potters who can burn bricks, laborers who carry bricks, and earthmakers who pile up, the tribe will definitely not have enough manpower, and if it is forcibly built, it will only affect the development of the tribe.

In addition, there was not much clay left of the tribe, and the triad soil used for the construction of the city walls was no longer clay, and ordinary soil was added directly, mixed with tough thatch, rhizomes, and slaked lime and fine sand.

To build a house with such a triple soil, it is just possible to use the plate construction method, erect wooden planks on both sides, just transport the materials and pour them in, and then use heavy wood and stone hammers to tamp them, saving a lot of manpower, and the defense is not lower than that of a brick wall.

There is no problem on the other three sides, but it is more troublesome under the mountain, and there are many fierce beasts in the grass, which greatly interferes with the work process.

Yeyang led a team of soldiers, and after on-the-spot investigation, he carried out a rough plan, cleared out a long firebreak in the edge area of the grassland, and directly took advantage of the dry season when the plants dried up, and ignited a large area of wasteland.

The smoke and dust were billowing and the flames were howling, the birds and beasts were gone, and the barren bushes outside the grassland were all turned into ashes.

The grassland is worthy of being a paradise for animals, a large number of fierce beasts are caught every day, and it has become an important source of meat for the tribe, fixed with more than 500 catties of flesh and blood, and it took six years before and after, and the four city walls were completed in turn.

The city gate is set up on all sides, the city gate is one zhang five high, and two heavy wooden planks with flat logs form a double door with a width of two zhang, and the city gate and the city wall facing the grassland will have new scratches every day.

There are a lot of traps in the buffer zone, but they can't withstand the number of more fierce beasts, and there are always fish that slip through the net to come to the city, and the city wall and city gate are quite badly damaged, especially the city gate, only waiting for the moat to be dug up.

When the time comes, on the outside of the double door, add a hanging door, and on the outside of the hanging door, add a bridge door, no matter how vicious you are, you will not want to enter the tribe. That's right, after the walls were built, the moat was built again.

In order to avoid the collapse of the foundation due to instability, the moat was separated from the city wall by a width of three zhang and a depth of two zhang.

Yeyang reacted, remembered the moat, planned the scope of the river, just dug it on the spot, made the raw materials of the city wall, killed two birds with one stone, and when the city wall was completed, the river was mostly better, and it only took half a year to repair.

Anyway, there is a stream next to the tribe, and it is too wasteful not to build a moat to drain irrigation, and the moat can not only improve the defense, but also raise big fish, and the big fish can be used for food when they come out of the water, and the water is the defense army.

The important thing is that after the tribe has been fishing uncontrollably in recent years, the fish in the stream has decreased significantly, and the fish resources in the stream are not many in the stream a few zhang wide, and it is inevitable that there will be a decrease.

After the moat was dug and the stream water began to be introduced, Yeyang led the people to build a fish pen in the river channel where the upstream and downstream city walls passed, leaving the fish in the river, which can be regarded as eliminating the hidden danger of water and giving children a safe activity area.

In the middle of the stream, there is no threat of big fish, and in the summer season, you can often see the tribesmen, bathing and rolling in the water, there are children and adults, they are happy, and they no longer have to worry about being bitten off by fish.

Cultivation followed, and the tribesmen carried light and hard bone rakes, and in the gentle slopes full of grass and wood ash, fertile fields were cultivated, and various plants were planted, and the area of wheat expanded rapidly.

Animal husbandry is also slowly advancing, and the flock of chickens has multiplied rapidly, and has spread into flocks, close to a hundred, with a fixed harvest of eggs, which can often be caught and slaughtered, and has become the result of domestication of the tribe.

Rabbits have also tried domestication, domestication is indeed successful, and the reproductive ability is also high, but it is too delicate to live, the forage has requirements, the environment has requirements, it is hot to die to live, cold to die to live, but there is not much meat.

The strongest adult male rabbit is about ten pounds, barely enough for an adult meal, the tribesmen are troublesome, and soon lost interest, and slaughtered one after another, leaving only a small amount for the child to play with.

There are also more than 20 pigs, which are big and easy to feed, but they are barbaric, and the pens need to be specially reinforced, ordinary people dare not approach, and the reproductive capacity is not high, and the growth rate is not hurried.

The breeding rate of sheep and deer is even more outrageously low, so far there are no more than ten, there are only seven or eight sheep, only five or six deer, most of them are caught cubs, only one sheep has given birth, and the deer has not yet given birth.

The three wolf cubs have also grown up, they have just become adults, the size of the jungle wolf is not small, several of them are parasitic in the tribe, they have never been hungry, and they have eaten a lot of waste materials from Yeyang refining medicine, and they have undergone abnormal changes, and each of them has a zhang long.

Education in the tribe also began to spread, and Chuanzheng found a few successful peers to teach the curriculum together, and children who reached the age of five were enrolled in school, and those under the age of ten had morning classes to learn the language, writing, and mathematics.

Those under the age of fifteen and over the age of ten take the turn to attend classes in the afternoon to learn the basics of weaving, sewing, grinding, pottery, farming, building houses, cooking, feeding, transporting, medical treatment, and gathering and hunting.

The unified weights and measures tool has also been taken out to make it, which cannot be used externally for the time being, but it facilitates the internal communication of the tribal people, and is conducive to a fair and just reward and punishment system, which can be regarded as an innovation.

Each ministry performed its own duties, the development of the tribe was in good order, Yeyang guided and planned for half a year, and saw that they had no major problems and could run on their own, so they took two flesh and blood warriors and left the tribe to start pioneering.

The so-called pioneering, there are only three purposes, to record the map of the jungle, to search for available minerals, to discover available plants, often go out for more than ten days, half a month to come back, to solve the doubts of the tribesmen.

The trade fair of the birth season, the tribe still sent people there, after all, it was the main way to exchange for salt, and he also found a lot of salt soil one after another, but the amount was not large, not enough for the tribe to use, so he could only rely on the fire tribe.

It was Yi Zhengmao who led the team, but Yeyang didn't follow anymore, he had already awakened his ability, since he could detect the fluctuations of the leader's and Wu's abilities, he couldn't guarantee that they could also detect himself, causing unnecessary trouble.

The trade of horns with the River tribe continued, and the wood tribe was in high demand, but the number of the River tribe was limited, and only a few pairs could be traded each year, all of which were used to make bows and arrows and expand the tribe's equipment.

Although he didn't go, he deliberately explained to Mao, and when he met something he hadn't seen before, he tried to change some back, but Mao didn't understand his thoughts, but he also carried out as he was told, and brought back a lot of useful things.

From this, he got potatoes, peas, two sub-grain crops, got a few cabbages, took them back to the tribe and planted them in the ground, he released his ability, and the vegetables grew roots, grew and matured, and got the seeds.

When he went out in the first year, he came across a mulberry forest, and found a few longing mulberry trees in it, and there were also wild silkworms on the mulberry trees, which he brought back and transplanted to the tribe, and carefully cultivated.

In the second year, he went out and encountered a peach tree, an apple tree in the third year, a Polygonum multiflorum in the fourth year, ginseng in the fifth year, a Ganoderma lucidum in the seventh year, and a bitter persimmon in the eighth year.

Bitter persimmon is very bitter, even if it is fully ripe, it will be astringent and lose teeth, making people unbearable, and it needs to be deastringent to become sweet, sweet and soft and glutinous taste, which has captured many people.

In the ninth year, Yeyang found a new clay land to supplement the scarce clay of the tribe, and in the same year, he found a large area of salt soil, and after extraction, he obtained nearly 100 catties of white salt, which was a bumper harvest.

In the tenth year, he came across a pine forest, and the pine branches were very good for igniting fire, and they could make ink, and with pine ink, it became necessary to make paper, and the brush was easy to make, and the pen, ink, paper, and inkstone could be collected.

The Four Treasures of the Scholar's Office had a great impact on culture and education, and the lighter and more convenient paper was certainly much more convenient than carving on birch bark, and in addition, he had a greater harvest when he went out for the last time.

In a misty mountain stream, Yeyang saw a miniature tree, with half-green and half-red fruits hanging on its branches, and a giant python the thickness of a water tank coiled under the tree, five feet long, was a rare fierce beast.

The power and blood of the Titan Python surpassed all the fierce beasts he had ever seen, even if everyone in the tribe shot, it may not be its opponent, he coveted the small trees and fruits, but he knew that he could not be beaten, so he silently wrote down the location.
