Elm wood is tough, the texture is clear, the hardness and strength are moderate, the planing surface is smooth, the chord pattern is beautiful, there is the pattern of "wenge", it is one of the main furniture materials, the characteristics of its wood, the heartwood is clearly distinguished, the sapwood is narrow and dark yellow, the heartwood is dark purple gray, the material is light and hard, the mechanical strength is higher, the texture is straight, the structure is rough, and it is more suitable for making a single bow.

From the very beginning of the production of the bamboo bow like a child's toy, the dragon tribe's bow-making technology has been continuously improved, with the special tools for making bows, the steps of making a bow have become more complicated, the time has also increased greatly, and the quality of the bow has also improved significantly.

Making a longbow also requires complex steps and a long time, and the main cost is still in the processing of materials.

To make a longbow made from elm, the straight part of the trunk should be selected, the texture should be uniform, and there should be no or as few knots as possible.

Most of the sapwood of the log is shaved off to obtain a bowed back material with a cross-section of one and a half inches square, the length of which is the size of a shooter.

From the cross-section, it is necessary to take the middle part, half of which is the wood core, and half of the sapwood, the wood core is relatively soft and compression-resistant, and is placed on the inside, and the hard and tensile sapwood is the outside, which can be judged by observing the wood grain of the cross-section, and the relatively sparse side is the outside.

By cutting one side of the wooden core, the material is trimmed to a thickness in the middle and slightly thinner at both ends, and then the ends are slightly narrowed by the two sides to slightly resemble a flat arm, and the cross-section is further trimmed into an octagonal shape with a planer at both ends.

In the trimming, the surface should be flat, the ends should be symmetrical, and the thickness should be consistent, so that the force can be even, and after the shape is cut, the elasticity of each section of the bow should be checked by bending test.

Because it is difficult to be completely uniform in the natural growth of wood, there may be some places that are harder, some places are softer, and the strength may not be the same just because the shape is uniform, so it is necessary to correct it through observation and slightly thin the hardness of the place.

Finally, the back of the bow is roughly adjusted, and the chord grooves can be filed at one and a half inches at both ends, and the outer side of the back of the bow is deeper, and the inner side is slightly shallower.

"The one who bows, knead the wood and the string is the arrow."

The most important process of making a bow is to bend it, the longbow is a simple arc type, there is no complex shape of the reverse curve bow, and it cannot be roasted by fire, which will reduce the tension of the bow, and it cannot be bent into place at once.

The process of bending is called "taming the bow", which is to make the bow back gradually adapt to the bending, and to do this requires a special bracket, which can be made of hardwood, one end is vertically dug a groove to support the bow back, the other end tries to be fixed vertically on the ground, and the sides are carved from top to bottom at an equal distance of one and a half inches eight to ten chord grooves, of which the first chord groove is seven inches from the head of the bracket.

Tie the rope to both ends in the relaxed state of the bow back, put the center of the bow back on the groove of the bracket, force evenly, slowly pull the string, hang it in the first string groove, the bow back is slightly bent, at this time, carefully check whether the curve of the bow back is smooth and even, mark the place that is too stiff, and trim and fine-tune the bow back after relaxation until you are satisfied.

Then pull the rope apart, gradually increase the opening and hang the groove downward, and keep trimming the bow back until a satisfactory and uniform arc is formed.

Every time you add three or four chord grooves, you can tighten the rope, this process can not be rushed, especially before each increase in the opening, it is best to let the bow back "rest" for a quarter of an hour to two quarters of an hour, so that the internal stress is released, so as not to damage the wood, each time it is tightened not too much, it is best to tighten one inch at a time, when the bow is suitable for the full bow opening, the bow is tamed.

Remove the bracket, brush the back of the bow with several layers of hemp seed oil as a moisture-proof protective layer, the oil is dry, you can hang the string, the bowstring is made of animal tendon tanning, elasticity and toughness are very good.

When hanging the string, the fixed opening is grasped at the distance between the bowstring and the center of the bow back reaches half a foot, and when the bowstring is tied, it is necessary to tie the knotted buckle in the shape of "8", which is simple but effective, and the tighter it is.

A longbow that was only slightly shorter than Yue Qi's height was made, and Yue Qi held the longbow that had just been completed, holding the bow with one hand and the bowstring with the other, and pulling the longbow into a full moon without much effort.

This is the first longbow approved by Yueqi, and it is a qualified product, and the longbows made before are all defective products in Yueqi's eyes.

Su Yan personally experienced this qualified longbow, and it took about a hundred catties of strength to pull the longbow into a full moon, which was not laborious, but it took more effort than pulling the recurve bamboo bow.

The longbow also has special arrows, the arrows of the longbow are a little longer than the arrows of the recurve bow, three feet long, the shaft of the arrow should be a little thicker, the arrow is made of copper, and the most important thing is that the shaft of the arrow should be straight in order to fly smoothly.

Arrows made of lighter materials such as aspen, poplar, elderberry, birch, willow, etc., have a long range; Heavy arrows made of heavy materials such as ash and horn wood are called heavy arrows, although they have a shorter range due to their larger weight, but they have stronger penetration at close range.

Su Yan and Yueqi experimented with the first qualified longbow, using flying arrows, the range of the arrows was more than 60 zhang, while the range of the recurve bamboo bow was only 30 zhang; Using heavy arrows, a distance of thirty zhang can easily penetrate the dragon tribe's standard rattan shield and rattan armor, and the same is true when the two are stacked together, and when the distance is less than twenty zhang, the dragon tribe's standard copper shield will also be pierced.

Terrible damage, even Yue Qi was surprised by the longbow he made, Yue Qi knew that the power of the longbow would be greater than that of the recurve bamboo bow, but he didn't expect that its power would be so great.

This is only the first qualified longbow, and when Yueqi's longbow skills improve, better longbows can be made, and the longbows at that time will be even more terrifying.

After seeing the power of the longbow, Su Yan immediately transferred a few carpenters to follow Yue Qi to learn how to make a longbow, just to learn, there is no need for mass production for the time being, and the recurved bamboo bow that has been mass-produced is enough for the dragon tribe to use.

Since the appearance of the recurve bamboo bow, the men of the dragon tribe have changed their views on bows and arrows, they can throw short spears at a distance of more than fifteen zhang, but after more than ten zhang, the accuracy and power drop sharply, on the contrary, the longest range of the recurve bamboo bow can reach thirty zhang, and the accuracy within twenty zhang is relatively high, only the power of this one defect. (The spear is taller than a human height, and the short spear is only a little shorter than the spear, not really short)

Short spears and bows and arrows have their own strengths, and although men do not turn to bows and arrows, they do not ignore bows and arrows, only men who have just come of age use bows and arrows, and their love for bows and arrows is already cultivated in their youth.

It doesn't matter if the men use bows and arrows as weapons or not, as long as some people use them, it is impossible for all warriors to use bows and arrows as weapons, it is better to use shields, pikemen, and archers together, and it is better if there are cavalry.

Su Yan didn't know that there was a tribe domesticating cattle on the south bank of the Great River, if he knew, Su Yan would definitely let the Dragon tribe develop to the south bank of the Great River in advance, attacking the Niu tribe to obtain cattle, the ox is not suitable for use as a cavalry mount, but it is a good hand in cultivating land, which can greatly save manpower, and can also use oxen to pull carts to transport materials.

Now that the longbow had been made by Yue Qi, one evening, Su Yan summoned the people of Source City to the square in front of the temple to personally demonstrate the power of the longbow to the clansmen.

Seeing the rattan shields, rattan armor, and bronze shields pierced by heavy arrows, the clansmen were dumbfounded, they couldn't imagine that the power of the bow and arrow would be so great, more powerful than the short spears thrown by the men, and the most important thing was that the range of the longbow was several times the distance thrown by the short spear.

Su Yan demonstrated the power of the longbow in the source city, and went to Akagi to demonstrate that the dragon tribe will not immediately equip the longbow, but it is also necessary to let everyone know the true power of the bow and arrow, so that everyone can completely accept the bow and arrow, especially the children, their preference for bows and arrows has deepened.

Because of the appearance of the longbow, the adults and children of the dragon tribe who like bows and arrows are divided into two factions, one group insists on the recurve bow, and the other group throws itself into the camp of the longbow.

Xiao Yue is a faction that attaches great importance to the recurve bow, and often praises the recurve bow in front of Su Yan and belittles the longbow.

"Husband, look at this longbow is so long, how inconvenient it is to use, and it looks so ugly."

"It's still beautiful and lightweight."

If it weren't for Satsuki's pregnancy, she would definitely become the leader of the recurve bow faction.

Su Yan calculated the time, Xiaohua Xiaoyue will give birth to a child in the third month of autumn, after checking the pulse, Su Yan felt that the two girls were pregnant with boys, Su Yan also told the two sisters so, so that the two sisters could rest assured, and the two sisters hoped that the rest of them was a boy.

However, there is a lot of error rate in taking the pulse, and Su Yan is not sure that his two children will be boys.

Eating and drinking every day, the bodies of the two sisters are plump, before the two sisters because of their martial arts practice and Su Yan's aesthetics, their figures are quite thin compared with other sturdy women in the Dragon Tribe, not skinny and thin, the thin bodies of the two sisters contain far more explosive power than people, in the Dragon Tribe, the force value of the two sisters is definitely more than half of the men.

Just as Su Yan's body looks thin and weak, his strength can rank second among the dragon tribe.

For the sake of the children, the two sisters are also fighting, and the figure they have always maintained is still eating and eating even if they develop in the direction of the women in the tribe.

In the eyes of the clansmen, the two sisters have become "beautiful", but on the whole they are still "ugly girls".

Why do men in primitive times like women with strong bodies, because men think that finding a strong woman as their spouse will give birth to better offspring, this situation has evolved into the aesthetic vision of men, women are strong and can do more work but secondary, this is a public ownership society, everyone is working together, there is no need to care who does more and who does less.

However, the aesthetic vision of the dragon tribesmen is slowly changing, after all, the king's figure is also thin compared to them, but the king's strength is very high, which makes their aesthetic vision slowly change.
