In the early spring of the eighteenth year, Su Yan ordered the three patriarchs of Zhi, Biao, and Shen to lead two hundred clansmen to fight against the three tribes temporarily named (new) No. 1, No. 2, and No. 3 in turn.

Su Yan is the king, Zhi, Biao, Yuan, Shen, and Song are Su Yan's courtiers or generals, with the increase in the population of the Dragon Tribe, Su Yan can't do everything, but also should sit in the middle and arrange all kinds of things to do, if everything is handled personally, it is estimated that Su Yan will eventually die of exhaustion.

For things like foreign wars, Su Yan has led the patriarchs many times, even if Su Yan is not there, the patriarchs can successfully complete the task, and it turns out that Su Yan's conclusion is right.

On the tenth day of the first month of spring, the three patriarchs of Zhi, Biao, and Shen led a team to fight against the No. 1 tribe, and returned smoothly in the evening three days later; On the sixteenth day of the first month, he set out for tribe No. 2 and returned four days later in the morning; On the twenty-third day, he set out for the third tribe, and returned four days later at noon.

Without Su Yan's participation in the three campaigns, Su Yan's courtiers also completed the battle task very well.

Where there are people, there is fighting, and human beings have been fighting since ancient times, and the target of human struggle is often resources.

Food is a resource, money is a resource, water is a resource, land is a resource, oil is a resource, and even women or people are resources.

In ancient China, the steppe peoples repeatedly invaded southward for resources, and in modern times, there have been many regional wars over oil.

The purpose of the dragon tribe's foreign conquest is resources, more precisely, for the population and for labor.

Only sufficient labor can do more, in the dragon tribe, fishing needs people, hunting needs people, domesticating animals needs people, farming needs people, mining copper ore and smelting copper ore also needs people, all aspects need people, there are fewer people can not carry out these projects at the same time, slowing down the development of the dragon tribe.

Just like a tribe with a good attribute and a tribe with a vicious attribute, a good tribe will not take the initiative to wage war against other tribes, everything depends on its own development, although the speed is slow, but it is better to be stable.

The vicious tribes relied on plundering the population and food of other tribes to develop rapidly, although fast, but prone to accidents, which greatly damaged the tribe's strength.

"Where there are people, there is fighting", and there is a saying that "where there is fighting, there are dead and wounded".

The powerful dragon tribe will have casualties when fighting abroad, not to mention other primitive tribes, the cannibal tribe that used to use wolves as totems, was defeated by the snake tribe and the tiger tribe twice, and the tribe's strength was greatly damaged, maybe the wolf tribe is still surviving, maybe the wolf tribe has been wiped out.

This year, when the dragon tribe went out to fight against the three tribes, one person was seriously injured and several people were slightly injured when they went out to tribe No. 1, and when they went out to tribe No. 2, they directly engaged in large-scale battles with tribe No. 2, and finally all the male clansmen who were taller than four feet in tribe No. 2 were killed, and two people were killed in battle, three were seriously injured and many were slightly injured, only a few people were slightly injured when they went out to tribe No. 3, and only a few people were slightly injured.

This loss is still within the range of the Dragon Tribe, which has a total population of more than 2,000, and the Dragon Tribe will not stop fighting outside the country because of the deaths and injuries of a few clansmen.

This year, the Dragon Tribe's three foreign conquests ended, and the sixty-one adult women and seventy-five minors of the No. 2 tribe were directly and forcibly integrated into the Dragon Tribe, and the three hundred and eleven people of the No. 1 and No. 3 tribes were temporarily reduced to slaves.

This year's No. 2 tribe is similar to last year's No. 3 tribe with pigs as a totem, most primitive tribes are patrilineal clans dominated by adult male clansmen, women and children are only vassals attached to men, once the man they are attached to is dead, in order to continue to survive, they can only choose a new man to attach to, which is the main reason why the dragon tribe can forcibly integrate them into the dragon tribe.

After bringing back the people of the second tribe, the adult male clansmen of the dragon tribe can carry it away directly as long as they like a certain woman, and they don't need to care whether the other party resists.

Often when choosing a woman, the high-ranking members of the dragon tribe, Zhi and Biao, will not make a move, they have enough spouses, and there is no need to compete with the clansmen.

Last year, the women of the Pig Tribe have fully integrated into the Dragon Tribe, and after they joined the Dragon Tribe, they did not resist at all, but they were appointed to work hard every day, silent as if the walking dead, thanks to the better life in the Dragon Tribe, they have shown their true temperament, and they can talk and laugh with other people.

This year's three foreign conquests are over, and the total population of the Dragon Tribe has once again made great strides compared to last year.

Last spring, the total population of the Dragon tribe was 1,592 and 154 slaves, and now the total population of the Dragon tribe has reached 2,056, including 272 adult males, 595 adult females, 597 boys, 551 girls, and 25 old and sick people.

There were also 311 slaves, of whom 48 were males, 117 females, and 141 minors.

The most important thing is the number of adult clansmen, they are the main labor force of the dragon tribe, fishing, mining, copper smelting, brick making, building houses, farming, all kinds of work are mainly done by adults, minors can only assist on the side.

After the conquest is over, it's time to be busy with other things, Su Yan gathered most of the adult labor force of the Dragon tribe for spring ploughing, one of them took a pickaxe or copper shovel in the farmland outside the Dragon tribe's residence and was busy plowing the field, the method of plowing the field Su Yan briefly demonstrated, the clansmen quickly learned, after cultivating the land again, they planted 700 acres of hemp and 1,800 acres of millet.

Hundreds of tribes worked together to cultivate these 2,500 acres of land in just a few days.

If the Dragon Tribe only has a hundred adult laborers, then these two thousand five hundred acres of land are enough for the Dragon Tribe to be busy, not only to cultivate the land and plant seeds, but also to weed regularly after planting, and harvest in the autumn, in addition to busy this farmland, how much time is left to do other things in a year?

The farmland has been cultivated, and there are still various things to be busy such as mining copper ore, smelting copper ore, and manufacturing hydraulic machinery, and Su Yan also plans to send an exploration team to carry out detailed exploration of the area inhabited by the dragon tribe.
