According to Su Yan's plan, the small city sits in the north and faces south, the northernmost side is the temple, the open space in front of the temple is 100 meters long and 70 meters wide is reserved for the dragon tribe meeting area, the area on both sides of the assembly area and the middle of the town is 70 meters wide is the residential area, the south side is left with a 60-meter wide area, the west side is used for captive animals, and the east side is built with toilets, bathhouses, pottery kilns and other functional buildings.

In addition, there is a school built next to the temple, and two toilets are built near the fence in the living area, one east and one west, and the toilets are divided into male and female areas, and finally there are drainage canals to prevent the town from being flooded by rain when it rains heavily.

One thing is most important, the house built by the dragon tribe's hometown is a brick house, but the roof of the brick house is paved with branches and wide leaves, and the wide leaves laid out have to be replaced almost every two years, and it is difficult for them to be stored for a long time under the sun and rain and insects.

Now in her new home, Su Yan tried to build a tiled house and build a tiled house, so she doesn't need to worry about roof problems in the next ten years at least.

The process of firing tiles is more complicated than firing adobe bricks, so Su Yan deliberately took his clan to spend a lot of money to make a batch of molds, no metal knives, only pottery fragments and stone tools, you can imagine how laborious it will be to make wooden molds.

The final tile is 25 centimeters long, 15 centimeters wide, and one centimeter (more) thick.

Pour the adjusted clay into the mold, the mold is a tile embryo, find a wooden stick with an adult's arm thick, put the tile embryo horizontally on the wooden stick, apply some pressure to the tile embryo to bend out an arc, this is the semi-finished tile after fixing, and the finished tile product is baked after high heat barbecue.

It is necessary to build a new brick house, and the specifications of the brick house must also be changed, Su Yan designed the specifications of the brick house, and finally chose a house that is five meters long, three .5 meters wide, two meters high on both sides, and two .5 meters high in the middle for construction, in which the height of the door is 1.8 meters, although the adult male standard of the Dragon tribe is about 1.5 meters, but their final height is generally about 1.8 meters, Zhi's height is more than 1.9 meters, and the height of Dali and Biao is close to two meters.

The new brick house will have a larger living area than the previous brick house, and can also live more people, the new brick house only has this specification, but according to the construction of the house is still divided into two types:

First-class houses, for Su Yan, Wu, patriarch and others to live, the inside of the house with a wall to separate the inner house and the outer house, the outer house to build a stove, the inner house to build a kang in the corresponding position;

Second-class houses, for ordinary people, built inside the house to build a stove, can provide a certain amount of light and heat for the occupants, can also use the stove to cook.

Both first-class and second-class houses have doors and no windows.

The first house built was the temple, which was made up of three second-class houses in parallel, and the first construction of a new brick or tiled house, especially the roof laying of the tiled house, had to be personally directed by Su Yan.

After the construction of the wall structure of the first tiled house was completed, Su Yan led the people to lay the roof.

The roof structure is divided into three layers, the bottom layer is a five-meter-long thick wooden pole, and a house needs five, one on the highest part of the roof, and the other four on both sides in the area between the roof and the eaves.

The second layer of the roof structure is made of twigs or rattans the thickness of an adult's finger and slightly finely woven.

It should be noted that the thick wooden poles, branches, and rattans used to lay the roof should be burned slightly, so that they can be used for a longer period of time, so that the roof will not collapse due to insects in a year or two.

The last layer of the roof structure is the tile, the fired tile is carefully placed on the second layer of the structure, the tile structure is divided into two layers, that is, after the bottom layer is paved, the gap of the bottom layer of the tile is covered with tiles and then covered with tiles, and it is difficult for rainwater to flow into the house through these two layers of tile structure, and a layer of tiles should be laid at the highest part of the roof, and finally the corners of the roof are pasted with clay.

In this way, the construction of a tiled house is completed, and the construction time of this tiled house is a little longer than the construction time of the previous brick house, but the previous brick house has to re-lay the roof in two years, and the tiled house hardly needs to maintain the roof, even if there is a leakage problem, it is good to replace a few tiles on the roof.

After Su Yan instructed the clansmen to build the first tiled house, the clansmen basically learned how to lay the roof of the tiled house, and then under Su Yan's command, five building teams were formed, and they would build five tiled houses at the same time, provided that there were enough adobe bricks and tiles.

After arranging everything, Su Yan went out with his escort team to explore, and the most important task was to collect and dig all kinds of herbs, followed by finding metal veins and crops.

Metal veins are the most difficult to find, Su Yan was not an explorer in his previous life, even if he is an explorer, it is difficult to find metal veins without advanced exploration equipment, and now Su Yan can only use the knowledge he has seen in books to find metal veins in the primitive era with the ancient method of finding metal veins.

Su Yan has found several kinds of crops, but a metal vein has been found, but it is difficult to mine, and it is difficult to find a metal vein suitable for mining.

The search for crops and the search for herbs were put together by Su Yan, after all, they are all looking for plants, and it is luck to be able to find a crop suitable for planting, and it doesn't matter if you can't find it, anyway, millet has been found now that it is a crop suitable for large-scale cultivation.

Gathering has become the most important thing for Su Yan to go out to explore, with the increase in the population of the dragon tribe, the dragon tribe needs more and more herbs, and there are many people in other primitive tribes who die of disease every year, especially children with poor resistance, and many children die of disease every year.

But everything has changed in the Dragon Tribe, simple minor diseases can be cured by a few witches, and the diseases that cannot be solved by a few witches are dealt with by Su Yan, and there are no difficult diseases such as AIDS and cancer in the primitive society, although the total population of the Dragon Tribe is increasing rapidly, but there are very few people who die every year because of diseases.

Not only diseases, but also injuries and poisoning, both of which used to cause death and can now be effectively treated.

In the primitive era, old age and death can be said to be the most desired way for primitive people to die, but there are very few people who can die of old age, maybe not one in a thousand, they may die of disease, they may starve to death, they may be injured and infected to death, they may be hunted by wild beasts, and they may be killed by other primitive tribes......

There are many ways to die, and it is almost impossible to choose to die of old age, whenever a tribe lacks food, the old people who cannot contribute much to the tribe are the first to give up, and some old people will also take the initiative to leave the tribe.

In the future, in the Dragon Tribe, people will become accustomed to old age and death, which is a manifestation of the Dragon Tribe's strength.
