Qiao Yu's foresight, his ability to see ten steps ahead, was something the Man clan greatly admired. Although they didn't think the flood would reach the tribe, since Qiao Yu felt the need to dig, then he did.
So, after the Dragon Tribe planted all the spring crops, the carpentry team learned to build carts, and the hunting team was divided into three parts: one part went out hunting, one part planted thorn vines and built fortifications, and the other part took the captives to dig ditches.
By the end of spring, the fortifications and ditches had been built and excavated according to Qiao Yu's requirements, and the carpentry team had also built its first carriage.
Knowing that all the parts have been made, they started assembling the carriage today. Not only the carpentry team, but also several elders and senior leaders such as Man and Qiang came.
Everyone was amazed at the complex shape of the axle.
"Someone come and pull it around." Qiao Yu said.
"I'll do it." Lu Yan didn't care about his identity and walked to the front of the car first, picking up the two handles.
"Let's start." He said, pulling the cart forward a few steps.
The other parts of the carriage are easy to make, but the wheels and axles are the most difficult. We were waiting here just to watch these two parts being assembled. The elders also knew that whether the carriage could move successfully or not depended entirely on the wheels and axles.
So everyone's eyes were fixed on the wheels and axles. Now they were seen turning, and the whole car was pulled forward by the road.
Lu Heshi shouted excitedly like children, "It's moving!"
"How is it?" Qiao Yu asked Lu Yan, "Is it hard?"
Lu Yan smiled and shook his head: "Not strenuous, that's good."
It is certainly strenuous. After all, although this car does not have a carport, and there is only a piece of spliced wooden boards on the frame, it is truly a wooden car. However, because the wooden boards are not very thin, the wheels also have a certain weight. The wheels are not made of rubber, but are covered with a layer of iron sheet, and the friction with the ground is quite large, so it takes a certain amount of effort to pull it up.
But his "no effort" was relative to the weight of these things.
If there were no wheels, and he had to pull these things directly, although he could pull them, it would be very difficult. Now the weight has been reduced a lot, which proves that vehicles are indeed good things.
"Great. I'll try it." Lu was old, but at this moment he was like a young boy, wanting to give it a try.
Not only him, but other elders were also eager to try it. Even Wu Yu, who had never participated in these things and was devoted to studying medicine, finally tried it and praised it as a good thing.
"Okay, let's harness the cow." said Qiao Yu.
The horses of the Dragon Tribe were very valuable, and Qiao Yu was reluctant to use them to pull carts. However, the cattle, being domesticated wild cattle, were very strong and were very suitable for pulling carts.
Under her guidance, Wu Yu and others pierced the noses of the cows. This way, whether they were plowing the fields, riding, or pulling carts, they no longer had to worry about them going crazy and hurting people.
After harnessing the oxen and driving them forward, everyone cheered as they saw the cart was being pulled steadily and turning smoothly.
"Next, your carpentry team will continue to build cars and make twenty of them," said Qiao Yu.
"good."
After looking at the carriage, Shi came over and said to Qiao Yu, "I had my men take the stone to everyone in the tribe to identify it. Some people in the Sun Tribe said they have a kind of ore that looks a bit like iron ore. But I don't know if it's the same."
"There are several other kinds of stones, different from the ones we showed them."
Qiao Yu was delighted: "That's great. Remember those people's names, and when we go to the Sun Tribe to mine salt, have them go with us. The ironwork team will go with them to identify the stones. They can also bring back some stones they haven't seen before."
As a leader, Qiao Yu faced the danger of the four tribes and the conflicts within the tribe. She could no longer be away from home for long periods of time. She had to stay at home and stabilize the rear.
Fortunately, the tribe had trained themselves well. The ironworkers could identify the ore and tell them whether it was iron. She no longer had to make the trip herself.
Although there was a suspected iron mine and the car was built, Qiao Yu did not let everyone set off to the Sun Tribe and the God Tribe immediately.
The trip back and forth, plus the time spent mining there, would take at least one to two months.
The elders' experience indicated that the last two months were the peak of heavy rain. In previous years, the valley tribe would relocate to a nearby mountain and stay there for two months before returning to their home village.
Whether it's raining heavily on the way there or on the way back, it's extremely dangerous. Summer rainstorms are often accompanied by lightning and thunder.
Therefore, Qiao Yu did not intend to let everyone go out in this season. After summer, autumn would be the best time to go out.
As expected by the elders, when all the captives of the Sun Tribe became free men and moved into their new homes, the summer rainstorms began to pour down.
The weather was like this every summer. In the past, people would have worried because heavy rain meant they couldn't go hunting, and not hunting meant a lack of food. If the rain continued for a long time, the less affluent would face starvation.
But now, with the ever-increasing number of rabbits and pigs in the farms, as well as the increasing number of goats and deer, people don't have to worry about food shortages at all.
Everyone stayed at home, attended classes in the morning, and in the afternoon used vines and straw that had been dried in advance to weave vine baskets, straw sandals, mattresses, and curtains.
In terms of cultural education, because there was no paper, pen or books, Qiao Yu could only teach everyone some simple words, count to one hundred, and calculate addition and subtraction of more than two-digit numbers, which was considered elementary school graduation.
If you perform particularly well in the exam, you can continue your studies and become a cultured person in the tribe in the future.
People from the Sun Tribe and the God Tribe who had just joined the Dragon Tribe and regained their freedom had to start all over again.
Originally, teaching everyone to read was what the elders of the Dragon Tribe were most proud of, as this was something that no other large tribe had.
But the elders had no interest in teaching these days. Instead, they gathered at the door, gazing at the dark sky with solemn expressions.
"Yu, I'm afraid a flash flood is about to break out. Is our tribe in danger?" Shan asked Qiao Yu.
The elders of the valley tribe are most sensitive to heavy rain because of where they originally lived.
Qiao Yu often goes to the city wall to watch the water these days.
She said, "I had the ditches outside the city dug wider and deeper. I just checked, and the water is flowing down the ditches into the river. Our tribe is much higher than the river, so even if the river rises, it won't flood our tribe. There won't be any problems for now."
