Last year, the dragon tribe had 137 adult males and 136 females, and this year it has risen again in small steps, with 179 males and 175 females.

By the end of the Dragon Tribe's foreign campaign, the total population of the Dragon Tribe had reached more than 13,600 people, including more than 1,800 adult males and more than 3,300 adult females.

In addition, there were 64 adult slaves and 85 juvenile slaves, a total of 149 men, all of whom were sent to the copper mining area to mine.

Su Yan didn't forget that there was another male clansman who didn't have a spouse last year, and there were four more adult male clansmen than female clansmen this year, so after the Dragon tribe conquered other tribes, Su Yan deliberately left five young women.

As the population of the Dragon Tribe continues to rise, some projects of the Dragon Tribe are being carried out at the same time, for example, when the Dragon Tribe is fighting abroad, the adult clansmen of Akagi and Yuancheng have already followed the arrangement of Luyuan to go to Zhucheng in batches to continue the construction of Zhucheng, and in the second month of spring, there will be batches of families moving from Chicheng and Yuancheng to Yuancheng.

During this time, the copper mining area, the smelting area smelting, the shipbuilding area shipbuilding, the carpenter workshop started, and various projects of the dragon tribe were carried out at the same time.

It is worth noting that the shipbuilding area, last year only started the construction of two A-boats, this spring has been on the river, and this year's shipbuilding area started to build three A-boats at the same time, is expected to be completed earlier than last year, the carpenter team of the dragon tribe is growing stronger.

Spring ploughing is coming, after last year's rush work, more than 300 double ploughs have been made, leaving two-fifths of the number in Yuancheng, and the remaining three-fifths of the number of double plows are sent to Chicheng and Zhucheng by boat, and at the same time, Su Yan arranged for the clansmen who will use double ploughs to plough the land to go to the two cities to teach other clansmen to use double ploughs.

While the spring ploughing has not yet begun, the tandem plough teaching is in full swing.

The use of the double plough seems relatively simple, one person pulls in the front, one person pushes in the back, and you can plow the field, but if you want to use the double plow well, there is still a lot of knowledge.

For example, the depth and strength of the plough, such as how easy it is to plow the land with a double plow, and so on.

Only if you learn how to use the double plough well, you can use the double plough to better cultivate the land.

Of course, even if you are a beginner to learn the double plow, the plough efficiency of the double plough is higher than that of the plough with a copper shovel and a pickaxe, and when people are proficient in the use of the double plow, the plough efficiency will naturally continue to improve, and it is very easy to double the field cultivated last year, and the land will be cultivated more in the future.

Although the double plow has appeared, what Su Yan wants more is to use the ox to pull the plow to plow the field, the strength and endurance of the ox is always higher than that of people, and the double plow ploughs the field, and people always need to rest.

By the time the three ships are built this year, the Dragon Tribe will have six A-type ships next year, and the six A-type ships can transport more than five hundred people at a time, plus a large amount of supplies.

Five hundred combatants is already a very large number, and in the south, a tribe with five hundred adult males has a total population of almost three thousand five hundred.

More importantly, considering many aspects such as weaponry, tactical coordination, and physical fitness, the combat team of the dragon tribe has higher combat effectiveness.

Su Yan couldn't wait for the southern area of the Great River, especially the cattle tribe, conquering the cattle tribe and obtaining cultivated cattle.

On the eve of spring ploughing, the work of migrating people from Source City and Akagi to Zhucheng officially began, and the first batch of people to migrate over would be the families of the adult clansmen who built the city, and the families of one-third of the hunting teams and reserve teams of Source City and Akagi would also need to migrate to Zhucheng in the first few batches.

This time, the migrated population no longer took the land route, but the water route, which was more convenient and fast, and the three boats were barely enough for the Dragon Tribe to use for the time being, and at the same time, the river next to the three cities of the Dragon Tribe was still a bit narrow, and there were not too many ships and larger ships on the river.

Before the first batch of population migrated, the Zhucheng Household Division was established first, and with the Zhucheng Household Division, the chaos in the process of population migration will be greatly reduced, and the Yuancheng Household Division, the Akagi Household Division, and the Zhucheng Household Division will all work hard for the smooth migration of the population.

At the beginning of spring ploughing, the population migration work was temporarily stopped, and the people who built the city in the bamboo city had to go to spring ploughing, and no one built a new house, so it was naturally impossible to migrate the population to the past.

In the farmland, one person pulls and one pushes, and a double plow moves back and forth in the farmland to plough the farmland.

The double plow is heavier, this is just for a person, the strength of two people combined, you can control the double plow very well, the previous double plow teaching, everyone tried to use the double plow, now the spring ploughing is coming, most of the people can use the double plow to plough the field, the use of a long time, the use of the double plow is also proficient.

Ploughing, sowing, and cultivating the soil, the two people who use the double plow are tired, then change the person, anyway, the double plough will not stop.

Everyone can see that with the addition of human ploughs, the time spent by the dragon tribe in farming this year will be much shorter than last year, and the area of cultivated land will be doubled last year.

Naturally, the more food the better, even if it is vegetarian rather than the meat that people like to eat the most.

When you are hungry, you know how happy it is to have a full meal, and now the dragon tribe has to arrange a fishing team to catch fish every day to meet the demand for food, but fortunately, the river is connected to the big river, and there is no need to worry about the fish in the river being caught.

In the past, it was a good thing to be able to fill your stomach with wild vegetables and plant roots, and meat was basically the food of adult people.

Now the children of the dragon tribe have wasted food, fortunately, the adults have not forgotten the hungry time in the past, they will continue to educate their children, not to waste food, food is precious, if you don't listen, then play a few meals, and the long memory will not waste food again.

In the busy, the spring ploughing is over, the construction of the bamboo city continues, the work of population migration is also continuing, the households of the three cities are very busy, and it is necessary to verify the data of the migrated population, and there can be no omissions and errors, once there are omissions and errors, it is easy to cause confusion.

Choosing a family, moving a family, determining a family, allocating houses, distributing food, and distributing goods are all the work of the household, and almost every step is inseparable from the household.

In particular, the personnel of the Zhucheng household department are busy from morning to night, and they have little time to rest in a day, sometimes they write until their hands are numb, their voices are hoarse, and their eyes are dazzled when they read data.
