After breakfast, the patriarchs were about to lead their respective teams to set off, but Su Yan stopped them.

"Have you ever seen a plant like this, probably the size of your arm, and growing very tall?" Su Yan opened the animal skin, and used black lines to outline the appearance of bamboo, one by one straight up to the clouds.

Several patriarchs looked at the bamboo painted on the animal skin, and carefully remembered whether they had seen such a plant.

After more than ten breaths, Zhi, Biao, Yang, and Song shook their heads one after another, only fate showed a different gaze.

"Wang, I seem to have seen this plant while exploring the south." Yuan said with some uncertainty.

"Then you will look for it tomorrow when you take the exploration team out, and if you can find it, cut down a few and bring it back, and if you can't find it, forget it."

"I see."

The patriarchs dispersed, and they took their respective teams, the fishermen of the fishers, the leaders of the chiefs, and the builders of the walls, and the exploration team of the edge had just returned, and they would explore the south again tomorrow, and today they were probably involved in the construction of the walls.

Su Yan returned to his house and sat down on a chair in front of the house, and on the wooden table in front of him was another animal skin, and the pattern painted on the animal skin looked like a bow.

Yes, it is indeed a bow, and the reason why Su Yan asked Yuan to find bamboo and bring it back was to use bamboo to make a bow.

When choosing a new shield for the dragon tribe before, Su Yan considered the situation when the dragon tribe would encounter the tribe that used bows and arrows in the future, the dragon tribe was about to equip a round copper shield on a large scale, but in the face of the arrow rain, the round copper shield could not block the arrow rain well, at that time, the dragon tribe needed to equip a new shield, and at the same time, Su Yan was also thinking about the dragon tribe equipping the bow and arrow.

Regarding bows and arrows, Su Yan had considered this problem as early as when he was in the Snake Tribe, at that time the Snake Tribe was still very weak and had no metal tools, but Su Yan could also use the only conditions to make simple bows and arrows.

Choose the right branches and branches as the bow, as for the bowstring, the straw rope is not usable, but it is very troublesome to use the tendons of animals, at that time Su Yan thought of a good idea, everyone in the snake tribe has long hair, and it is completely possible to use hair to make a bowstring, as for the arrows, it is simpler.

With the conditions of the snake tribe, a simple bow and arrow can be made, but this bow and arrow is too simple, and the range, power, and accuracy of the arrow are not enough.

Compared to the short spear, or throwing spear, the bow and arrow require more skill, and although the bow and arrow can be thrown longer than the short spear, the longer range is useless in the densely wooded jungle.

On the contrary, spear throwing is more flexible than a bow and arrow in the jungle, and in the end the bow and arrow are left behind by Su Yan.

However, as the snake tribe becomes the dragon tribe, the environment faced by the dragon tribe is also changing, the jungle is not suitable for the use of bows and arrows, but in the plains, bows and arrows will dominate the battlefield.

Now the dragon tribe has not encountered the use of bows and arrows, but it is better to take out the bow and arrow earlier than later, and the bow and arrow made at the beginning is bound to be simpler, and with the passage of time, the improvement of technology can make better bows and arrows.

In the future, if the Dragons encounter an enemy equipped with a bow and arrow, the Dragons can easily defeat the enemy with a bow and arrow with a longer range, higher accuracy, and greater power.

One of the most important reasons why the Spring and Autumn Warring States Qin State was able to defeat the other six countries was that Qin's bows and crossbows were better than the other six countries, and even in the era when firearms were just appearing, firearms could not replace the position of bows and arrows.

A simple bow can be made quickly, but a delicate bow can take a long time to make, and a series of complicated processes to make a delicate bow can even take two to three years.

The bow is mainly divided into two parts, the bow body and the bowstring.

There are many kinds of materials for the bow body, which can be a single material or a variety of composite materials, and the properties of the materials play a decisive role in the performance of the bow.

The material of the bow body is the upper wood, the second is the wood, the oak tree, etc., and the bamboo is the bottom, that is to say, bamboo is the lowest in the materials for making the bow body, but it is also the easiest to use bamboo to make the bow body, and Su Yan is ready to start with bamboo.

Before, Su Yan asked several patriarchs about the traces of bamboo, and several patriarchs often went out hunting with hunting teams, and they might find traces of bamboo, but in the end, they could only see it, or in the southern region that they had just explored.

Most of the Suyan bamboos like warm and humid climates, abundant in tropical, subtropical and temperate regions, the northern winter is cold, it is normal to find no traces of bamboo, and it is definitely a surprise to find traces of bamboo in the southern region of the Dragon Tribe.

If no bamboo is found, Su Yan will choose other materials to make the bow.

The material of the bow body has been determined, it is bamboo, and it is only waiting for fate to lead the exploration team to the south to bring the bamboo back.

As for the material of the bowstring, in Su Yan's memory, the ancient Chinese bowstring material is mostly cow tendon, and the tendon of some other animals is expected to be okay, but Su Yanxiang tried to use twine to make the bowstring.

There is no bow yet, and Su Yan doesn't know why the ancients didn't use twine to make bowstrings, probably because twine is easier to break than cow tendon in the process of repeated pulling.

This situation did not have much impact on Su Yan, even after Su Yan made the bow and arrow, it would be impossible for the Dragon Tribe to equip the Dragon Tribe with bows and arrows on a large scale in a short period of time, after all, the main area of activity of the Dragon Tribe was still the jungle.

Bamboo for the bow, twine for the bowstring, bamboo for the arrows, there are only two kinds of materials, the twine is ready, just waiting for the exploration team to bring the bamboo back.

In fact, bamboo has several uses, for example, bamboo shoots can be eaten, bamboo is used to make chopsticks, and the most important thing is to hold water in bamboo tubes.

Three days later, Yuan led the exploration team back, and with it came a batch of emerald bamboo.

There is indeed bamboo in the south of the Dragon Tribe, and the scale of the bamboo forest is quite large, Su Yan checked this bamboo and found that this bamboo is indeed suitable as a material for the bow body.

Selecting the bamboo suitable for making a bow, Su Yan took two carpenters to get busy, and each of the two carpenters was responsible for making a bow.

There are two options for thinking about making a bow, a recurve bow with a slightly more complicated process, and a simple straight-draw bow (the English longbow is a straight-draw).

Compared to a bow with the same straight arm, the recurve bow stores more energy, allowing the arrow to be shot with higher kinetic energy.

As a result, the recurve bow can be made shorter than a regular bow while maintaining its power, which makes the recurve suitable for use in places where longer weapons would be inconvenient, such as jungles, forests, or horseback.

Comparatively, a traditionally straighter longbow causes a "cascading" effect – the more the bow is drawn, the more force required to pull the bow increases.
