More than an hour later.

A group of hunters who went to the dock to welcome the goods to come back with big and small items on their backs, throwing them in the middle of the yard, panting and loudly complaining that Feng and others had ridden their horses away, causing them to come back with the goods.

Xu Chen was so amused and crying.

The invention of any new tool will make human civilization progress, but as the dependence on new tools becomes stronger and stronger, human laziness becomes greater and greater, the physical condition is also getting worse.

He remembered that the hunters of the tribe used to go outside the valley to be extremely relaxed, and they ran like flying. But since they had horses, these guys have become more and more lazy. They don’t even bother to leave the valley if they don’t ride horses. If this continues, they will be afraid that in a few years, they will all start to get fat, because it can be seen that in the past two years, the hunters of the tribe have generally become thicker and obviously gain weight.

It seems that we need to increase our training efforts on weekdays to keep them healthy and physically. Otherwise, if this continues for a long time, we will become a group of obese primitive people who are pampered and have good health.

However, as new tools and weapons continue to innovate and invent, they will greatly supplement human physical weaknesses.

Just like the invention of bows and arrows, it allows humans to attack prey and enemies more easily and accurately, and the use of horses will greatly enhance human movement speed.

With the emergence of rafts and horses, the exchanges between tribes have become faster and more convenient, and tribes are no longer as rare as before.

At least now, it is common for the Ba people and Wu people to ride horses to each other.

Even the Yu Gong Clan and Gonghuo Clan one or two hundred miles away have at least one trip every month.

However, the speed of communication is accelerating, and freight exchanges will become more and more. The transportation of large quantities of goods occupies manpower and animal power. Every time the Ba people transport goods back and forth from the valley to the river beach and dock, it also consumes a lot of manpower and material resources. More than ten horses are not enough.

It seems that it's time to invent the carriage.

He can't take care of other tribes for the time being, but it is still necessary for the Ba people to go back and forth twenty miles from Hekou to build a road. If there are carriages, today, these goods will be arranged at most two carriages and two horses, and they will be pulled in one go.

What's more, with a carriage, even if women, children, young and old want to go to Hekou and even the Wu tribe, it will save a lot of horsepower, and you don't have to go all out every time, causing huge waste.

Thinking of this, Xu Chen turned around and went into the house, wiped off some of the useless weapons drawn on several of the ceramic boards, and began to draw the structural diagram of the carriage.

The structure of the carriage is very simple, just a wheel and a frame, which is not much different from the rural ox cart. If you want to make it more refined, you can install a truck bucket or even a carport on it.

But the wheels are the most difficult part to make the carriage.

If he hadn't created bronze-level sword and axe tools before, he would have no way to do it. But now with these sharp metal tools, he could still try it out. I don't know if it's easy to use, but I believe it will be able to do it.

After all, I have never eaten pork and seen pigs running.

He has never seen two-wheeled carriages in ancient times, but he has seen many two-wheeled carriages, ox carriages and even hand-held tractor carriages in rural areas.

When he was a child, the wheels of his cart were his toys. He once pushed them back and forth in the yard with his friends.

Therefore, Xu Chen sat in the room to draw and wipe, and slowly the structural diagrams of the frame and wheels appeared on several ceramic boards.

Outside, the wind and a group of hunters ran in and out, as if they were injected with chicken blood, carrying an axe and hatchet shouting, and they couldn't stop as if they had discovered a new toy.

A group of women including Muba and Ye were cleaning up the items that Feng brought back from the two tribes and registering them into the warehouse.

The little witch who was reading the diary in the next room was so quarreled that she couldn't calm down, so she had to put down the animal skin diary and found that Xu Chen was not in the yard. She habitually walked out of Xu Chen's door and took a look, and found that he was drawing pictures with concentration.

The little witch walked behind him with her skirt in her arms and looked at the square and round figures drawn on the ceramic boards, her face full of mist.

"Your Majesty the Witch King, is Moga painted?"

The little witch finally couldn't help but ask softly.

Xu Chen had actually known that the little girl had come in for a long time, so he said with a smile: "This is called a car. After making it out of wood, you can use human or animal power to walk, and you can pull a lot of people and goods at once."

"Really?" The little witch instantly enlarged her eyes.

"Well, there were no metal knives and axes before, and it was very troublesome to deal with wood, but it should be done now. Look, this is the wheel... This is the shaft, and the frame is on it. When you are transporting goods, you can trap it on the frame. If you are sitting, you can also add a carport like a wooden house. People will not be afraid of wind and rain when sitting inside..."

Xu Chen gently explained to the little witch the structure and purpose of the carriage on the ceramic plate.

The little witch basically didn't understand it. She was completely stunned by the extremely complex artificial creature.

This thing is much more complicated than a raft with sails.

She also heard Xu Chen explain it for a long time before she understood how the sails used the wind to move forward in the river.

Of course, the Ba people are not without complex things at the moment, such as children's cars, lounge chairs, double-layer hammocks, etc., and the structure is also very complex.

However, compared with large rafts and carriages, this kind of household utensils is completely incomparable. After all, the use and size are huge.

Just talking about rafts, they are tools that can come and go in the turbulent rivers.

According to Xu Chen, the carriage can also carry a large amount of goods and large tools that fly around in a flat place. The faster the horse can run the car.

The little witch knew that Xu Chen had a huge imagination, but when faced with this sudden innovation, her little mouth was still shocked and opened for a long time and could not close it. Before she knew it, she almost leaned on Xu Chen's back.

Through the touch of the clothes, Xu Chen was a little distracted.

Although he always thought that the little witch was still a little girl, the pampered witch, and the most pampered and adequate food and nutritional supplements in the past or two years, and the soft and weak body, had begun to grow up unknowingly. He was no longer the little witch who escaped and could not even wear clothes.

Time flies so fast!

After counting on my fingers, I have been traveling through time for almost four years.

Xu Chen sighed in his heart.

Before I knew it, I had grown from a 12 or 13-year-old boy to a mature and tall young leader at the age of sixteen or seventeen.

Ye rushed in from outside with a ceramic plate.

The little witch blushed and took a step back, her heart beating a little faster.

She knew the relationship between Xu Chen and Ye, and also knew that it was impossible for her to have any relationship between men and women with Xu Chen.

But she just couldn't help but want to get close to Xu Chen and stay with him all the time. Even when it was late at night, she would always think of Xu Chen next door tossing and turning and unable to sleep. Sometimes when she listened to Xu Chen and Ye making some noises in the room in the middle of the night, she felt blood flowing all over her body, and her whole body was so hot that she couldn't fall asleep.

Occasionally when she communicates with Xu Chen alone, she will always lean on it without realizing it, as if Xu Chen had an irresistible temptation, exuding a breath that made her intoxicated, and she was deeply trapped in it and could not extricate herself.

However, Ye no longer had jealousy and hostility towards the little witch. Instead, he walked to the table enthusiastically, handed the pottery board in his hand to Xu Chen, and began to report the goods brought back with excitement on his face.

There are more than forty animal skins, more than ten kilograms of gold, a basket of various gems, ten horns of beasts, twenty brocade feathers of various colors, one hundred and twenty kilograms of salt, two hundred kilograms of lead, and three hundred kilograms of tin...

Except for salt and tin, Xu Chen was not interested in anything else at the moment. He asked a few more questions and learned that there was a bag of snowflake-like salt powder in the salt sent back this time, so he was excited to throw the pottery board out to watch.

The evaporation of salt is very slow, especially in winter. The salt sent by the Mongolians to the Yugong tribe in the first two times were stone salt crystals, which were cleaned up by them and the indigenous savages after digging from the salt brine area. However, this time, the first batch of real salt was finally sent, which made him very happy.

After the goods in the yard have been counted, some of them have been moved into the warehouse.

All four bags of salt are placed in the backpack.

These salts are stored in animal skin pockets, two of which are salt crystals and two of them are white salt particles.

Although it is a bit turbid and there are some mud and sand impurities inside, it can be seen that this is indeed real salt, which is completely different from stone salt. If you dip it with a finger and lick it, it will have a very pure salt taste, which melts in your mouth and is also very salty.

The Ba people are now familiar with salt crystals and eat them every day, but they have never seen this kind of snow-white salt grains before. Therefore, a large group of men, women, young and old are watching around, and some people can't help but grab a little and put them in their mouths to taste.

"Xianga!"

Those who tasted it couldn't help but exclaimed excitedly.

Xu Chen smiled and said, "This is called salt grains. They are dried with salt water. They taste better than salt crystals. They are more convenient to cook and marinate. However, it takes a long time to dry salt, so it is more troublesome to get it out."

"Chenga, the Mongolians say that it rains a lot in spring and summer, and it is difficult to get salt grains, and it may be less. I hope you don't blame them!"

The wind rushed over to report with a big golden axe.

"Well, I won't blame them. Next time I go and tell them that if there is too much rain in spring and summer, there is no need to dry salt. Just dig more salt crystals. By the way, how much has the Thunder Clan left this time?"

"The Thunder Clan left five bags, all of which were salt crystals!" Feng quickly answered.

"Well, it's very good. We only need dozens of kilograms per month now. However, spring is the time when wild vegetables are fresh and tender. The excess salt can be used to make some pickles and can be eaten in clay pots in autumn and winter." Xu Chen nodded with a smile.

"What is pickled vegetables?" Someone couldn't help asking curiously.

"Pickled vegetables are like pickled fish. After washing and drying the freshly collected wild vegetables, rub them with salt and put them in the clay pot to store. They will not break for a long time. The pickled vegetables are salty and sour. If they are well pickled, they taste very delicious and as delicious as bacon!
