In the space of five years, the valley has completely changed. The advent of cement has turned all the houses where everyone lives into cement houses, and even two-story or even three-story houses have been built; Every household has an iron pot, and of course, the clay pot has not been abandoned, which can be used to boil water and stew meat, and the iron pot is used to fry meat; Iron was also used in other ways, and the warriors of the tribe wore iron knives and guns, bows and arrows with iron arrows, which were more staggeringly lethal, and iron accessories on farm tools made them more effective; The stone belt made several boats, and occasionally took people to wander the river with them, fishing with woven fishing nets; The crops in the farmland are growing very well, not to mention the yield, two harvests a year, and the harvest is enough to feed all the people who have fallen for a whole year. Now the people of the tribe are not worried about the problem of not having food to eat in winter, they are worried about too much food, and they are afraid that it will be spoiled.

"Why don't you go to the annual tribal fair and exchange your food for something else?" Turtle offers.

Li An thought about it and agreed. Although there are many materials in the tribe now, there are still many materials that are not available, such as sugar. There was no sugar beet sugar cane near the valley, not even beehives, and Lai An hadn't eaten anything sweet for years. She hopes to be able to exchange sugar at the rally, and to be able to find sugar beet sugar cane through the people at the rally.

The Xia tribe loaded the endless grain into the cart, and it was their tamed bison that pulled the cart, and each cart sat three warrior escort carts, and Li An and Yu sat in the last cart. When the convoy appeared at the bazaar, it frightened everyone in the bazaar. Everyone began to inquire about the situation of this tribe called "Xia", and some people simply ran to the people of the Xia tribe to get close, but they were all fooled by the scheming turtle.

The tribal warriors unloaded the grain from the cart, and the huge amount of grain shook the people in the bazaar. In order to sell food that no one else knew what it was, the turtle had his men light three fires and roast sweet potatoes, corn and potatoes for people from other tribes. When the other tribes ate the sweet corn and sweet potatoes, they cried out to exchange them for the two grains, and asked what the flame was.

"Flame is a good thing, it warms the body in the winter, and it can cook and roast raw food, and cooked food is much better than raw food." As he spoke, he had a few pieces of meat roasted and distributed to the people in the market.

The people at the bazaar had eaten barbecue and became more interested in fire, so they asked the turtle if they could exchange it for fire.

"No need to exchange, we can teach you the art of making fire for free." Turtle Dao, who praised the kindness of the divine envoy in his heart, even taught the skill of drilling wood to make fire to others for free.

As the turtle spoke, he asked people to start drilling wood to make fire, and explained it himself. Many people picked up wooden branches and followed the study, and really got out of the fire and lit the fire in front of them.

"It's lit, it's lit." The people in the bazaar shouted excitedly.

The turtle watched as a man reached for the flames, and hurriedly reminded them of the danger of the flames.

Everyone listened to the turtle's warning, and all of them were cautious, and took his words to heart, especially after the turtle said that fire would burn people to death, and if the fire spread carelessly, the entire tribe would be burned, and these people were a little frightened. Some people have the idea of giving up bringing fire back to the clan. But when they think back to the taste of cooked meat and cooked food, they extinguish that idea.

The people of various tribes hurriedly took the things they brought to the Xia tribe in exchange for food, especially after the turtle could grow potatoes, corn and sweet potatoes by themselves, these people's actions to exchange food became even crazier, and they rushed to the side of the turtle, for fear that they would be one step too late and would not be able to exchange for food.

Turtles do not refuse, nor do they pick goods to be exchanged for food. In between grain exchanges, he also recommended Chinese cloth, pottery, wooden furniture and tools to others.

The eyes of the people of the other tribes were straight: this Xia tribe was too powerful and powerful, and there were so many magical and useful things.

Some people who had bad intentions because of the Xia tribe's large amount of food and wanted to attack and rob the Xia tribe were so frightened that they immediately extinguished this thought, and it can be seen from the things that the Xia tribe took out that they were not easy to mess with, and they went to attack the Xia tribe, and it was their own tribe that was destroyed in the end.

However, there are also some small tribes who have other thoughts, their tribe has fewer people, fewer warriors, there is not enough food to eat every year, the children born are either starved to death or frozen to death, the number of people in the tribe is getting smaller and smaller, and it is really impossible to support it. These tribes came to the market with the intention of finding a big tribe to take refuge, and after seeing what the Xia tribe took out, these people all made a choice in their hearts.

The bazaar lasted for three days, and all the things brought by the Xia tribe were replaced, and many messy things were exchanged, some things were useful to the tribe, and some looked useless, but the people of the Xia tribe had a general understanding that no matter how useless things were put into the hands of the divine envoys, they would become useful. This is also the main reason why they do not refuse.

Among the things I got back was honey, and I was lucky enough to get sugar cane. Primitive people did not know how to make sugar, but they found sugar cane to taste very sweet, so they used it as one of the foods. This time, the tribe that found the sugar cane brought several bundles of sugar cane in exchange for food.

When Li An found the sugar cane, he immediately called the tribe that found the sugar cane and exchanged it for a cart of sugar cane with roots and sugar cane seedlings for ten carts of grain. The people of this tribe were very happy to go back to their tribe to collect sugarcane, and one cart of sugarcane was exchanged for ten carts of grain, which was a huge profit. Although these sugarcanes taste good, they are not full at all, where can they reach potatoes, corn and sweet potatoes, just that taste, isn't it the same as sweet potatoes?

The people of this tribe finally arrived at the market with a cart of sugar cane before the end of the market, and the people sent back to the tribe to get grain by Li An also brought people to drive ten carts of grain. The two sides made a deal that was very satisfactory to both parties, and Li An generously left the cart for grain to the tribe. But the oxen that pull the cart will not be left for them. They want oxen to pull carts, and they can go and tame bison themselves.

Although the people of this tribe did not get the oxen to pull the cart, they already felt that they had made a lot of money when they got the cart, and this thing called the cart was really good, it could carry so many goods, even if there was no bison to pull the cart, as long as four or five warriors were together, they could also pull the cart full of goods. You must know that it takes more than ten warriors to carry so many goods in a truckload.

The other tribes are envious, jealous and hateful to this tribe, how come their tribe doesn't have what the Xia tribe desperately wants?
