"These are for our tribe?" The leader of Aoki was a little incredulous, the dragon tribe had such a good intention, sending so many things to the Aoki tribe, one rattan shield can be exchanged for four animal skins, and a rattan armor needs at least ten animal skins, these things can be exchanged for hundreds of animal skins in total, so it was given to the Aoki tribe.

Unconsciously, Aoki's leader's impression of the dragon tribe was slowly changing.

"Yes, the gift has been delivered, it's time for us to go, and we have to go to a distant land to trade with other tribes." After saying this, Zhao Lin waved his hand to the leader of Aoki and turned to leave.

The leader of Aoki also waved his hand, and watched Zhao Lin Yingxi and more than twenty dragon tribe warriors get on board, and the five A-type ships set sail.

The leader of Aoki stood on the bank of the river in a daze, watching the dragon tribe fleet go away, but the surrounding clansmen became noisy.

"It's the vine shield of the dragon tribe, and the rattan armor." "This rattan armor has one that belongs to me." "I don't want rattan armor, if only I could give me a rattan shield." ”

The clansmen talked a lot, and even some clansmen touched the rattan shield and rattan armor with their hands, of course, it is not that getting the rattan shield rattan armor means that the rattan shield and rattan armor belong to them, and in the end, the ownership of the rattan shield and rattan armor must be determined by the leader.

As the dragon clan fleet moved away, the leader of Aoki recovered, and he said to the people around him, "Take the vine shield and rattan armor, and we will go back." ”

Stepping on the road back to his residence, in the distance, the leader of Aoki saw Wu standing on the edge of his residence, and it seemed that Wu was not worried about the sudden arrival of the dragon tribe fleet.

Soon, the Aoki chief returned to his place of residence.

"Chief, what are the dragon tribes doing this time?" Wu asked.

Leader: "This time the dragon tribe is here to send gifts, vine shields, and rattan armor. ”

Wu: "The dragon tribe just sent those to us like this?" No, these things are worth a lot of hides. ”

Leader: "Yes, it's all sent to us directly, without asking for anything in return." ”

Wu was a little stunned, it was hard for Wu to imagine that the Dragon Tribe would send so much equipment to the Aoki Tribe so easily.

"Alas, in the future, we will look for opportunities to repay the Dragon Tribe." Wu said with a sigh.

"Good"

……

Since the beginning of spring, there have been many changes in the dragon tribe, the biggest change is that the breeding area in the city has been abolished, and the livestock raised in the breeding area have been dispersed to each family, and each family has to take a little time to feed the livestock every day.

At the same time as the livestock are distributed to each household, the livestock breeding competition is held at the same time, and the end date of the competition is until the first snow of winter, and the livestock breeding competition is held every year.

There are many items in the competition, such as who raises the most chickens, who raises the heaviest chickens, who lays the most eggs, who raises the heaviest pigs, and so on.

In the city, the top ten families in a single competition will be rewarded, mainly animal meat and eggs, bronze cast gadgets, and most importantly, the first place in a single competition, their families will receive third-class merit.

It is a good thing that good livestock is tantamount to meritorious service, and all families are trying to take care of the livestock in their own yards, and everyone is also looking for free time to go to the people who used to work in the breeding area to learn from the experience of raising livestock.

The king decreed that a clansman who had worked in the breeding area was not allowed to conceal the knowledge of raising livestock, and that if the cattle of his own clan were well raised, the clansman would be rewarded.

Seeing that the people were very involved in raising livestock, Su Yan was satisfied with the method he had come up with to hold a livestock raising competition.

In Su Yan's view, the centralized raising of livestock is conducive to the expansion of the livestock population and the reduction of manpower wasted on raising livestock, but there is a very important problem that restricts the centralized raising of livestock by the Dragon Tribe.

Very helpless thing, concentrated raising livestock, once there is a livestock disease, or a more serious infectious disease, will soon be infected with other livestock, an infection is a large area, this sick livestock can not eat, can only be killed, once there is a livestock disease, will cause major losses to the breeding area.

Although the manpower input for raising livestock has increased, it has to be said that once the livestock of a certain family are infected, it is difficult to disperse the disease and will not cause the livestock of other families to be infected.

The treatment of livestock diseases is also a relatively difficult problem to solve in modern times, what pig epidemics, cattle epidemics, chicken epidemics often occur in modern times, once the epidemic breaks out, it is necessary to slaughter and bury all the livestock involved to prevent the spread of the disease, Su Yan is in this era is a troublesome thing, and it can only be dealt with in this way for the time being.

Fortunately, the dragon tribe continues to expand and is building a fifth city, and even if an epidemic breaks out in one city, it will be difficult for other cities to be infected.

The epidemic of livestock is so troublesome, if there is an outbreak of an epidemic that can infect people, it is terrible, the original deer tribe was a disease that caused a great loss of strength, and was attacked by two tribes, and had to go away.

Now the number of exchanges between the dragon tribe and the outside world is increasing, and the dragon tribe itself does not have epidemics, but it is easy to bring back epidemics from the tribes they communicate with.

Su Yan was a doctor in his previous life, and he paid more attention to this place, and he was ready to think of the means he could use to deal with possible outbreaks at any time.

In addition to communicating with the outside world, it is also easy to transmit diseases from the corpses of dead people.

Su Yan didn't know when the custom of entering the earth for peace began, anyway, almost all the tribes where the dragon tribe and the dragon tribe had exchanges were cremated, and the corpses of the clansmen were burned with fire, so as to avoid the bodies of the clansmen from being eaten by wild beasts, and the corpses were packed in coffins to avoid the corpses being eaten by wild beasts.

Cremation is the best method, and the corpse will be burned, and naturally the corpse will not cause epidemics.

Su Yan single-handedly established the medical system of the dragon tribe, at the beginning, only the witches of each clan and the disciples of the witch learned Su Yan's medical skills, and the witch would also record the medical skills he learned and the actual treatment of patients, forming a medical book, the first person to edit the medical book is Su Yan, and the second person will be the witch who writes the medical book.

With the increase in the population of the Dragon Tribe, the number of people who learn medical skills is also increasing, among which a small number of clansmen in the hunting team and reserve team learn to deal with physical wounds, and Su Yan even took out the medical skills of using needles and threads to suture wounds.

Using needles and threads to stitch up wounds, this is a very terrible thing for the people of the dragon tribe, but this medical skill is taught by the king, the tribesmen try carefully, it turns out that the wounded who use needle and thread to suture the wound is better than the wounded who does not suture the wound, and now, the dragon tribe people have accepted the use of needle and thread to suture the wound.

This year, the Dragon Tribe education system has been reformed, and there are medical professional courses in the technical college of the Senior School, which will train a large number of people who can heal for the Dragon Tribe in the future.
