Xiao Yue's way of pulling the bow is not quite right, Su Yan taught Xiao Yue to draw the bow by hand, and did not try to shoot arrows, although the house where Su Yan lives is around the square, but there are clansmen walking in the square, and the arrows are copper arrows, and it is not good to accidentally hurt the clansmen.

I didn't try archery, but Satsuki was very interested in bows and arrows, and even agreed with Su Yan that she would shoot arrows outside her residence tomorrow.

Su Yan smiled and nodded in agreement.

In the blink of an eye, a few days passed, and the bamboo bows in the hands of Su Yan, Xiaohua, and Xiaoyue were replaced with the three newly made ones, and the skills of the two carpenters in making bamboo bows were getting better and better, and the bamboo bows made were more exquisite, and the performance of the bamboo bows had also been improved to a certain extent, but the time for making a bamboo bow had also increased.

In their spare time, the two carpenters also made a batch of short bows with a length of only two to three feet according to Su Yan's instructions, these were for the juvenile clan to play with, and along with the short bows, there were also bamboo arrows, in order to prevent them from hurting others with short bows, Su Yan also warned the children not to sharpen the front ends of the arrows.

The people of the Dragon Tribe showed two completely different reactions to the appearance of bows and arrows, Su Yan, Xiaohua, Xiaoyue and the boys of the Dragon Tribe were very fond of bows and arrows, while the adult male clansmen of the Dragon Tribe did not have much feeling for bows and arrows, thinking that light bows and arrows were far less useful than short spears.

Especially after Biao easily pulled off a bamboo bow, their sense of the bamboo bow was even worse.

Speechless, this bamboo bow can't withstand Biao's strength, and even can't withstand the strength of most of the adult men in the dragon tribe, and it needs a bow made of better materials to withstand their strength, as for Biao's strength, wood is not good, and the only thing that can withstand Biao's strength is probably the iron tire bow.

Put the bamboo bow and the short spear together, or the short spear is better, the primitive man's strength is large, throwing the short spear can have more power, using a short spear or arrow to attack a wild boar, unless it is to attack the head of the wild boar, if it is to attack the thick and hard fur of the wild boar, the arrow shot by the bamboo bow is basically impenetrable, and the short spear is very likely to penetrate.

Su Yan didn't care about the men's senses, the bamboo bow had to be made, and the carpenter had to accumulate experience in making bows and arrows in making bamboo bows, so that he could make better bows and arrows in the future.

The boys are very fond of bows and arrows, and when they have no free time to work, they will take out their own short bows and arrows, play and compete with their friends, compare who shoots farther, and who shoots accurately, and even flocks to the fields and orchards to find small birds as prey.

Originally, the boys used to throw "short spears" to play, but now they have all turned to archery, and the speed of change has become a stark contrast to the attitude of the men.

Time passed, Yuan took the exploration team to explore the southern machine of the Dragon Tribe as usual, and the location of several tribes' settlements appeared on the animal skin map, Yuan often took the exploration team to the Moon Tribe as a guest, and also gave the Moon Tribe a lot of gifts, those gifts in the Moon Tribe are undoubtedly precious, there are gifts, the people of the Moon Tribe are very welcome to come to the Moon Tribe as a guest.

Yuan Zhen was a friend of the leader of the month, and at the same time, Yuan also thought about letting the Moon Tribe join the Dragon Tribe, and Yuan thought about when he should invite the Moon Leader to the Dragon Tribe as a guest, so that he could see the strength of the Dragon Tribe, and only when he saw the strength of the Dragon Tribe, the possibility of letting the Moon Tribe join the Dragon Tribe would be greatly increased.

In addition, the exploration team also has a task, which is to cut some bamboo from the bamboo forest from time to time and come back to make bamboo bows.

The communication between Yang on behalf of the Dragon Tribe and the River, Bear, and Tree tribes is also continuing, and Yang leads the team to take turns to go to the three tribes once each time, but the number of return visits of the three tribes is not the same, and the most frequent communication with the Dragon Tribe is the Bear Tribe, followed by the River Tribe, and the Tree Tribe exchanges are less.

Probably because the people of the tree tribe live in the trees, they and the primitive people who live on the ground are two ways of life, not too willing to communicate with the tribes living on the ground, but the dragon tribe visits so many times, and also brings a lot of gifts that are very precious to the tree tribe, the tree tribe can only visit once in a while.

A very interesting thing, similar to the original Eagle Tribe, when the Eagle Tribe and the Dragon Tribe communicated, they found that their tribe did not have any unique products that could be given as a gift to the Dragon Tribe, and finally gave a food that the Eagle Tribe liked as a gift to the Dragon Tribe.

The same is true for the three tribes of River, Bear, and Tree, the three tribes searched carefully and did not find a special product that could be given as a gift to the Dragon Tribe, and finally they could only give the unique wild vegetables eaten by their tribe as a gift to the Dragon Tribe.

Cabbage is another vegetable suitable for large-scale cultivation by the dragon tribe.

Su Yan likes to eat sauerkraut very much, maybe you can try pickling cabbage to make sauerkraut.

The dragon tribe communicated more with the three tribes of river, bear, and tree, and the people of the three tribes learned more and more about the dragon tribe, and they returned to the tribe to tell other tribesmen what they had seen and heard in the dragon tribe, and a group of people who envied the life of the dragon tribe appeared in the three tribes.

Envy a better life, this is a normal thing, everyone wants to live a better life, but it is very difficult for the three tribes of River, Bear, and Tree to achieve the life of the Dragon Tribe, and it is the luckiest thing for the three tribes to be able to not starve to death and not freeze to death in winter, but it is very difficult to do these two things.

Su Yan hasn't asked Yang to invite the three tribes to join the Dragon Tribe, it's not time yet, after a while of communication, the two sides know more before it's time to send them an invitation, sending an invitation too early will only make them wary of the Dragon Tribe, and it won't be good if they are scared to move the tribe far away.

The clansmen were busy, Su Yan was not idle, after being busy with the shield and then with the bow and arrow, after the bow and arrow thing was busy, Su Yan began to be busy with the water stone grinding again.

The thing of hydraulic propulsion is very simple, there was a hydraulic bellows before, and there is also a water mill, this part can be easily constructed, and it is mainly the part of the stone mill.

Stone mill is a kind of machinery used to process rice, wheat, beans and other grains into powder and pulp, usually made of two round stones, the mill is two layers of the plane, the junction of the two layers has a texture, the grain enters the middle of the two layers from the hole above, moves outward along the texture, and is ground when rolling through the two layers to form a powder.

The structure of the stone mill is relatively simple, but it takes a lot of time to make the stone mill, and grinding the stone is the most time-consuming.

There is no shortage of people polishing stones in the dragon tribe, originally the dragon tribe was a stone age tribe, and the most used stone tools were stone tools, and some stone tools are still used.

Su Yan drew a sketch of the stone mill, and directly instructed several clansmen to find the stone and then polish the stone.
