The first step in building a city is to build a wall, the first step to build a wall is to dig a foundation pit, the winter has just passed, the ground of the land is still a little hard, you have to wait for the first spring rain to come to moisten the soil, then the temperature will also rise to a more suitable temperature, it is suitable for excavating the foundation pit.

So the main thing the people of the Dragon Tribe are doing now is to make bricks and fire enough adobe bricks.

Building a small city that covers an area of only more than 120 acres of land, the number of adobe bricks needed is also very much, taking the four brick walls of the small city as an example, the total length of the wall is 800 meters, plus the height of the foundation wall is three meters, the width of the wall is 20 centimeters, plus the one meter of low wall behind the wall, so calculated, it takes at least 640,000 adobe bricks to complete the construction of the wall.

Six hundred and forty thousand adobe bricks, it seems to be a very large number, as if it is a difficult project to complete, Su Yan also sighed a little after calculating this number before, and doubted in his heart: Does the Dragon Tribe need to use so many adobe bricks to build a wall?

Brick wall, earth and stone wall, fence wall, net wall, these are the four kinds of walls that can be selected for the new home, without cement, the earth and stone wall is likely to be washed down by heavy rain in the rainy season, and the fence wall can not even stop the beast, and finally only the two options of brick wall and net wall are left.

The construction speed of the net wall is very fast, the net wall has a certain blocking effect on the beast and the primitive man, but the net wall has to be changed once in two or three years, the primitive people and some beasts can also climb over the net wall, the beast with sharp teeth, the primitive man with sharp stone tools can also destroy the net wall, think about it carefully, the blocking effect of the net wall can only be said to be general.

The most effective wall is still a brick wall, but the construction period of the brick wall is too long, but after in-depth calculations, Su Yan still chooses to use adobe bricks to build the wall.

Excluding the manpower and time required for fishing, hunting, and other labor, it is estimated that the dragon tribe can have 200 adult laborers involved in brick making every day.

In a year, excluding the autumn harvest, winter, rainy days, etc., the remaining days of labor are only 130 to 140 days.

Assuming that the wall was to be built in a year, each adult laborer would have to burn twenty-five adobe bricks per day, and twenty-five adobe bricks per person per day would not be much.

The reality is that each adult laborer produces at least fifty bricks a day, and only five bricks per hour are required for ten hours of daytime, and the relatively light labor of firing the bricks can be left to minors and pregnant people.

The adobe bricks fired in "one year" were not only able to build brick walls, but also 130 brick houses were built from the remaining adobe bricks, each of which housed an average of 17 people, or more than 2,000 people in total.

Build a small city in a year!

If the dragon tribe just appeared a few years ago, it would definitely not be able to do it, and now the total population of the dragon tribe (counting slaves) has exceeded 1,000, and there is enough labor force, and a big project like building a new home is enough to be completed in a year.

It has to be said that the population is everything of a tribe.

Burning adobe bricks, constantly firing adobe bricks, fishing teams and hunting teams will come to the river to dig clay bricks after fishing and hunting, and after the daily labor, most of the dragon tribe will participate in the process of firing adobe bricks.

Originally, Su Yan estimated that the Dragon Tribe could burn 10,000 adobe bricks in one day, and when it really started, more than 7,000 adobe bricks were fired on the first day, more than 10,000 adobe bricks were fired on the second day, more than 13,000 bricks on the third day, and even more than 15,000 on the sixth day.

After ten days of stabilization, the earth bricks fired by the dragon tribe hovered between thirteen thousand and fourteen thousand pieces every day, mainly to find clay and spend a certain amount of time, but fortunately there was a large river and a small river, and there was enough clay for excavation, even if the clay was exhausted, they could dig their own soil and add water "and clay".

After the first spring rain, the soil was moistened by the rain, and the temperature also rose to a relatively comfortable temperature, Su Yan used hemp rope as a tool to draw two square areas on the land that was cleared, the small square side was 200 meters long, and the side of the large square was about 35 centimeters away from the side of the small square.

After drawing the two squares, Su Yan asked the tribesmen to dig a half-meter-deep foundation pit in the area between the two squares, an eight-hundred-meter-long foundation pit, with an average of four meters of length per person, no pickaxes and shovels, the people of the Dragon Tribe can only use pottery fragments or stone chips to dig the soil, in order to speed up the speed of digging the foundation pit, every evening Su Yan will also let the tribesmen add water to the foundation pit that has just dug out a little foundation, and artificially moisten the land.

With the efforts of the clansmen, the foundation pit was dug in only three days, and the next step was to build a brick wall.

Building a brick wall consumes bricks much faster than the people of the Dragon tribe can burn adobe bricks, and if there are enough adobe bricks, the dragon tribe can build the walls of their new home in a day.

In the busyness, the residual cold of winter completely dissipated, and when the spring sowing season came, Su Yan took fifty adult clansmen and more than a hundred underage clansmen to follow him to plant various crops, and it seemed that fruit trees were also crops.

First of all, Su Yan took out two-thirds of the millet in his hand, and didn't care whether the millet used as seeds was good, and directly planted these seeds in a location relatively close to his new home, planting a total of two acres of land.

After planting millet and then planting hemp, the total area of the wasteland is more than 3,000 acres, minus the 120 acres of the new home construction area, there are still more than 2,900 acres, and finally Su Yan will leave 300 meters wide land in the outermost part of the wasteland area for planting pepper and other fruit trees, and the remaining area is used to plant hemp, with an area of about 1,400 acres.

By the time the pepper seeds were planted and the seedlings of various fruit trees had been transplanted, it was already the third month of spring, and the wall of the new home had just been completed two days earlier.

There are eight exits to the new house, two in each direction, four in each direction, each four meters wide and equipped with two gates two meters wide, made of sticks thick as children's wrists, with branches and rattans, so that as long as the gates are closed, wild animals cannot pounce on them.

After the construction of the walls of the new house was completed, the construction of the house of the new house began, and the first house built was a temple.

There would be no statue of the dragon god in the temple, which was a little too difficult for primitive people, and they could only put the totem pole in the temple to temporarily replace the role of the statue.

The temple is a place where the dragon god is worshipped, and it is also the place where the high-ranking members of the dragon tribe meet, and the high-ranking people will discuss various matters in the temple.

The temple is located in the northernmost part of the new home, and in front of the temple is a large open space that serves as a meeting place for the dragon tribe, where sacrifices, bonfires, blind dates, and so on can be held.
