At the moment when slavery appeared in the Dragon Tribe, Su Yan knew that the slaves would secretly plan all kinds of riots/movements or escape actions, this is a normal situation, if a human being is enslaved by other humans, even if it can meet the needs of slaves for food, clothing and housing, but personal freedom is restricted, and there are no women, slaves will naturally resist.

If women are distributed to slaves, it will probably make the slaves' resistance lower, but Su Yan doesn't have this idea, if the slaves have women, it means that the slaves will have the next generation, and the descendants of the slaves will be slaves, and even the number of slaves will be more than the population of the dragon tribe in the future, and the hidden crisis can be imagined.

It is better to treat the "renewable" slaves as one-time "consumables", and do not allow the slaves to have offspring, so that the number of slaves can be controlled, and even in the end, the dragon tribe can no longer find a new tribe to fight, the last slaves are exhausted, and slavery disappears from the dragon tribe.

The experience of the previous life has fully proved that slavery will eventually be eliminated by history, and there are all kinds of slave riots/riots in Su Yan's memory, which can be replaced by slaves when the dragon tribe is short of labor, and when the dragon tribe no longer lacks labor in the future, there is no need to leave such a dangerous thing as slaves.

At the beginning of spring this year, the Dragon Tribe had 282 adult slaves and 591 juvenile slaves, a total of 873 people; By the end of the autumn, there were 938 adult slaves and 1,413 juvenile slaves, making a total of 2,351.

Su Yan understands that there are many slaves, which will naturally cause various problems, there have been dozens of slaves who were killed when they escaped or resisted, and there were only a few fools among the slaves, and most of the slaves knew that they could not fight alone, and that there should be more people united to escape or resist together to have a chance to succeed.

Su Yan had already expected that there would be a slave collective riot, as long as this matter was investigated, all the masterminds, big and small leaders of the slave riot, and those who resolutely resisted would not need to be merciful, and all of them would be killed to deter other slaves.

Even if he kills hundreds of slaves, Su Yan will not feel distressed, you must know that in this year, the number of slaves will increase by 1,478, and in the future, the dragon tribe will continue to fight against the outside world every year, and there will be more slaves.

However, it is also a trouble to have more slaves, and more people will be needed to guard the slaves.

A male can guard three adult slaves or about six minor slaves, and a female can guard two adult slaves or four minor slaves.

This ratio can only be maintained, and once there are fewer people guarding slaves, the frequency of slaves running away or resisting will definitely increase greatly.

Now the two thousand three hundred and fifty-one slaves of the Dragon Tribe need at least five hundred people to guard them, but fortunately, the slaves are also labor, and it is not a big problem to mobilize five hundred people to guard the slaves in the past.

The heavy labor of mining has been completely handed over to slaves, and some of the almost tamed slaves can also work on brick-making and even cultivating fields, and perhaps in the future, the people of the Dragon Tribe will be freed from most of the heavy labor and leave all this heavy labor to slaves.

……

The temperature is constantly falling, while the source river and the Yellow River are not yet frozen, Su Yan took a boat to Yangcheng, this is the last time Su Yan went to Yangcheng this year, when the river is frozen, there is the Yellow River block, the frozen river can not determine whether it is stable, in winter, the communication between Yangcheng south of the Yellow River and the three cities north of the Yellow River will be completely interrupted.

Su Yan was very worried about the situation in Liyang City this winter, so he took advantage of the fact that the river was not yet frozen, and went to Yangcheng in person to discuss the things that need to be paid attention to in Yangcheng in winter.

Coming to Yangcheng, Su Yan walked around Yangcheng a few times in the company of Zhi, and went to the families of some clansmen to take a look, after the end of the condolences, Su Yan and Zhi sat together, Zhi knew that Wang came over before the winter was coming, there must be something important.

Su Yan: "Zhi, is there enough food reserves here in Yangcheng?" ”

Snake Wisdom: "That's enough, most of the food has been distributed to various families. ”

Su Yan nodded and continued: "After winter comes, the river will freeze, and then the connection between Yangcheng and other cities will be cut off, and once there is any problem here, it can only be solved by Yangcheng itself." ”

Snake Wisdom: "Please rest assured that Yangcheng can solve any problem in the face." ”

Su Yan: "Youzhi sits in Yangcheng, I don't worry, but there are two things that Zhizhi needs to pay special attention to, one is the slaves imprisoned in Yangcheng, and the other is to guard against foreign invasion in winter." ”

Hearing the king's words, the snake wisdom became cautious, these two things really need to be taken seriously.

The 2,351 slaves of the Dragon Tribe were scattered to four cities, and the number of slaves held in Yangcheng Prison exceeded 500, and there were 100 adult clansmen who needed to guard the prison every day to prevent slave riots.

Zhi knew that the slaves were going to riot en masse in the spring of next year, and even Zhi wrote to Su Yan proposing to kill all the slaves.

In fact, slaves are less likely to have problems in the winter, after all, the winter is very cold, and even if a slave escapes, it is very difficult to survive in the cold winter.

That's why the slaves were talking about looking for an opportunity to riot next spring, when most of the slaves were gathered in the copper mines, and many of them rebelled together, according to their ideas, even if they couldn't defeat the guards, some of them could escape, and the escapees would be united enough to survive in the jungle by hunting.

The most important thing is to guard against the attack of other tribes in Yangcheng in winter, the situation on this side of Yangcheng is not comparable to the situation faced by the three north of the Yellow River, the number of the northern tribes is a few hundred at most, while the number of the southern tribes is a few hundred, and there are many tribes with more than a thousand people.

Especially the last time Yangcheng was attacked by the five tribes, it was enough to gather seven hundred people, this is not all the strength of the five tribes, if the five tribes gather all their strength, the number of people gathered may even reach two thousand, this number is more than the number of adult clansmen in Yangcheng at that time.

With the strength of Yangcheng at that time, it can still repel the enemy, but fortunately, most of the tribes are not familiar with night battles, once they encounter night battles, Yangcheng will be in trouble, and the role of bows and arrows and short spears in night battles will undoubtedly be greatly reduced.
