At the end of winter, Su Yan will enter the twenty-eighth year of his life, and it is also the sixteenth year of the establishment of the Dragon Tribe.

Twenty-eight years old, in modern times, he is just a young man, and now he is a middle-aged person, and what is even more helpless is that at least half of the people in this era will not live to be twenty-eight years old.

Now the total population of the Dragon Tribe has exceeded 20,000, which is the result of Su Yan's efforts for 20 years, the snake tribe was still the tiger tribe that was extremely weak at the beginning, and slowly developed into a powerful tribe that now crisscrosses the Yellow River Valley.

Natural breeding coupled with continuous foreign conquest and plundering of the population is the guarantee of the rapid development of the Dragon Tribe, but this development speed is still too slow for Su Yan, and it took twenty years for the Dragon Tribe to have a population of 20,000.

How many twenty years of Su Yan's life are there? After Su Yan's death, will the strength of the Yilong tribe be able to withstand all kinds of natural and man-made disasters?

Su Yan didn't know that Su Yan wanted to find a way to speed up the development of the Dragon Tribe, and wanted to leave a stable country for future generations before he died.

In the past, Su Yan just wanted to live a better life for himself and the people around him, but now Su Yan thinks about the next generation at most, which is the change brought to Su Yan by the birth of Ping Hean.

Recalling the knowledge of his previous life, Su Yan thought of a plan that could be tried, and if this plan could be successful, the development speed of the Dragon Tribe would continue to accelerate on the basis of today.

For example, now the development speed of the dragon tribe is small steps and jogging, and after the successful implementation of that plan, the development speed of the dragon tribe is to run in stride, and this plan has one of the most important things - boats.

Ships, the Age of Discovery, fleets from Europe swarmed into Africa, with only one goal - slaves.

Slave traders set out from Europe, sailed to Africa, and after capturing African natives in Africa through various despicable methods, they transported slaves to the Americas, sold them to American plantation owners, and then transported gold and industrial raw materials from the Americas back to Europe, which was a lucrative "triangular trade".

There are two main ways for slave traders to capture African natives, one is to organize their own people to capture them, and the other is to trade cheap industrial goods with the chiefs or kings of the African region, that is, to exchange industrial goods for slaves.

The former was time-consuming and labor-intensive, mainly in the first stage of the slave trade, while the latter was the second stage of the slave trade, where a large number of slaves could be obtained quickly for a small amount of money.

It has to be said that the dragon tribe's foreign conquest is somewhat similar to the slave trade, the dragon tribe plunders the population through foreign warfare, and adult men and sensible teenagers are reduced to slaves to make up for the shortage of labor in the dragon tribe, the difference is that the dragon tribe integrates women and unsensible boys into the dragon tribe.

The dragon tribe's foreign conquest is in the first stage of the "slave trade", which is to personally go to the war to plunder the population, and Su Yan's plan is to move the dragon tribe from the first stage to the second stage, and obtain the population from other tribes through trade, which will undoubtedly greatly accelerate the development of the dragon tribe.

What's more important is that the people obtained through trading, their hatred will no longer be on the dragon tribe, their hatred will be on the tribe that destroyed their family, and the dragon tribe can even find people from slaves who behave well to give the identity of the dragon tribe.

When it comes to trading with other tribes, the role of boats comes to the fore: walking by land, without horses, is slow, but when it comes to navigating rivers by boat, the speed of the water route is much faster than that of the land route.

Moreover, most of the tribes live close to water sources, and there are many tribes on both sides of the Yellow River and its tributaries, and you can get in touch with these tribes more quickly by water.

Compared with the dragon tribe, the other tribes are undoubtedly backward, in the transaction between the two sides, the dragon tribe has more choices, bronze cast exquisite weapons, coarse bronze cast farm tools, pottery, white salt, fishing nets, linen, etc., the dragon tribe mainly obtains the population from other tribes, whether this population is its own tribe or plundered from other tribes.

In addition, horses and crops that the dragon tribe does not have can also be traded, and it is self-evident that under the role of horses, various crops are also indispensable to the dragon tribe.

Think about it, when the fleet of the Dragon Tribe sailed on the Yellow River and its tributaries, the various Dragon Tribe specialties loaded on the ship were exchanged for population with other tribes.

Population is also more important to other tribes, especially women, and almost all other people will be killed, and now the dragon tribe has given these tribes a chance to exchange the people they originally needed to kill in exchange for something that makes them happy.

Of course, the Dragon Tribe's trading partners are mainly the tribes in the south of the Yellow River, and most of the tribes in the north of the Yellow River that the Dragon Tribe comes into contact with are still working hard for the survival of the tribes, and it is not excluded that there are powerful tribes on the north bank of the lower reaches of the Yellow River.

In addition to the slave trade, Su Yan also wanted to try to invite other tribes to join the dragon tribe in the form of a clan, but the premise of the invitation was that the dragon tribe had a good relationship with the target tribe first.

Just like the Deer Clan, the Rabbit Clan, the Mountain Clan, the Eagle Clan, etc., if they weren't very familiar with each other, how could they finally join the Dragon Tribe in the form of a clan.

If the dragon tribe suddenly sends an invitation to an unfamiliar tribe, it is a strange thing for the other party to directly agree.

Find some kind tribes that don't like to fight abroad, first give some specialties of the dragon tribe and build a good relationship with the other party, every time you communicate, you must try to talk about the strength and prosperity of the dragon tribe with the other party, and you can even invite people from the target tribe to the dragon tribe to have a look, and wait until the relationship between the two sides goes further, at this time you can send an invitation to the target tribe.

The fact that tribes have joined the Dragon Tribe in the form of clans means that the improvement of each component of the Dragon Tribe's population directly improves the strength of the Dragon Tribe, rather than only increasing women and boys, only increasing women and boys, and the strength of the Dragon Tribe is not much.

The establishment of the Ministry of Industry, the Ministry of Agriculture, and the Ministry of War, the reform of the education system, the dispersal of livestock to each household, there is a lot to be done next year, and now there is another slave trade, and it seems that the importance of the slave trade is above other things.

The slave trade is too important, Su Yan needs a person who can reassure himself to carry out this task, the two people in the Dragon Tribe who reassure Su Yan the most, one is Snake Wisdom, and the other is Lu Yuan, the two of them can be called Su Yan's right and left hands, and they can both be independent.

Snake Wisdom is in Yangcheng, Yangcheng has just been established, and it is inseparable from Snake Wisdom, so you can only choose Luyuan, the city lord of Bamboo City is vacant, and Zhou Ming, the head of the Chicheng household, will take over.
