The straight bow is a long-range weapon prepared by Li Xiang for the youth camp, and its design is mainly inspired by the ancient Chinese monolithic bow, the British longbow and the traditional bamboo-wood composite bow. After making a few prototypes and experimenting with them, Li Xiang handed over the task to the craftsman camp to continue.

The production of straight bow tires mainly uses bamboo and wood. It can also increase the tensile force and improve the tensile curve by means of external rib wire and inner corner piece, of course, the cost will soar.

One of the woods requires outstanding toughness, while the other requires good accumulation. The main tree species are fir wood, mulberry wood, elm wood and tuomu, which are all common tree species in Xunyang Mountain.

Bamboo slices need to be more than three years old, and they can only be bowed after drying and roasting in the shade.

Li Xiang was holding a finished bow tire in his hand, and the straight bow tire that was not wound was slightly reversed, and the ends were reversed. The two pieces of wood and bamboo are baked together and then oiled and tied, and because of the process, the bow tires take on a black and yellow color.

The handshake made of fishbone fits the five fingers and has grooves for the arrow.

Li Xiang was inspired by Da Zhou's bow-making books and advocated the development of this straight bow. Compared with the English longbow, the straight bow has added a lot of unique processes.

Straight bows require special processes such as phased drying, baking, arching testing, stress testing, and bonding. Among them, the bow formation test refers to the temporary fixation of components without tying them to evaluate the performance of bow formation and adjust it in time.

Carpenter Zeng and Zhang Qingping found that it took three months to make this kind of bow. When the process is mature and the division of labor is clearer, so that it can be standardized and produced on an assembly line, the production cycle can be shortened again.

The tensile force of the straight bow is currently 30-40 kg, and the tensile force will be greatly improved after using the tendon horn piece. The current straight bow process is still very immature, and its life and performance are very limited, after all, this weapon has only appeared for less than two months.

The current straight bow is 1.5-1.6 meters high, and because it requires a longer wood to provide charging, it can be made smaller than the compound bow. It is not easy to buy controlled materials such as animal tendons and silk in the village, so the bowstring accounts for half of the total cost.

The length of the straight bow and arrow is 80-90 cm, and the shaft of the arrow is thicker. Light arrows are made of balsa woods such as poplar, birch, and willow for projectiles; Heavy arrows are made of heavy woods such as ash and hornwood and are used for direct fire.

The materials used for the arrows are also common in the Xunyang Mountains, and the chicken, duck and goose feathers directly used for feathers are the same as cold-proof clothing and down jackets, which are mainly purchased from Xunyang Mansion.

Zhang Qingping set three kinds of arrows for the straight bow, namely diamond-shaped barbed arrows, long cone-piercing arrows and three-edged armor-piercing arrows.

The main feature of the diamond barbed arrow is that it is easy to manufacture and works well against unarmored or lightly armored targets. 60 grams in weight and 90 cm in length. The smaller cross-section with barbs is both penetrating and lethal.

Long cone-piercing arrows, armor-piercing are good and cheap. 60 grams in weight and 90 cm in length. The wound is small, the damage is small, and the penetration is good.

Three-edged armor-piercing arrows, which are more expensive. It weighs 85 grams and is 80 centimeters long. The drag is balanced, the flight is stable, and there are barbed blood grooves.

The straight bow should not be fully aimed for a long time, otherwise it will cause great damage to the bow tire. Hearing Zhang Qingping and Carpenter say this, Li Xiang was very helpless. But since the straight bow has such a hard wound, it can only be made up for from the tactics. After all, it is a cheap bow that requires mass production, and there are several shortcomings that are understandable.

The straight bow developed by Li Xiang and Jianghuying does not require high materials, and only needs two kinds of wood with outstanding toughness and good storage strength, and special bamboo pieces are laminated and baked. Then apply tung oil and fix five places with hemp rope.

When the straight bow is stored for a long time, the bowstring needs to be removed to relieve the stress. Then place in a cool, dry place and brush regularly, wind and open the bow. Of course, this is only an estimate, and the specific discrepancies depend on long-term experience.

Zhang Qingping's ancestor has been making bows for a long time, and proposed that the energy efficiency of straight bows is not as good as that of horn bows. In other words, with the same 40 kg of pulling force, the arrows shot by the horn bow are much more powerful than the straight bow.

Li Xiang expected the problem of energy efficiency, but as long as the pull force went up, after all, it was only a temporary main battle weapon. If the efficiency is low, increase the pulling force, strengthen the training if you can't pull, and fight more people if you can't shoot accurately!

If conditions permit, Li Xianghate can't immediately pull up an army of firearms. Having said that, the main function of the bow and arrow is to suppress firepower, and Li Xiang intends to work the tactics of war, relying more on the strength of the collective rather than the skill of each soldier.

All in all, the straight bow borrows a lot from the design of the bamboo-wood composite bow, such as bamboo-wood fitting bow tires, baking modulation, etc. It also combines the essence of the English longbow and the ancient Chinese monolithic bow, which is suitable for large-scale manufacturing and low cost. However, the energy efficiency is low, it is not suitable for long-term aiming, and the current life is relatively limited.

Li Xiang asked He Mingjiang to put the 3 mm thick iron plate at the foot of the mountain in the distance, and then made a "lady first" gesture to Liu Susu. Liu Susu gave him a blank look, then stepped forward generously, took a 40-kilogram straight bow and began to test, of course, the straight bow used for the test was one out of ten.

The first is a 60-gram and 90-centimeter-long cone armor-piercing arrow, which is mainly used for medium and long-distance armor-piercing, and Liu Susu found that at a distance of 90 meters, the arrow just passed through the iron plate.

This is followed by a 60-gram 90-centimeter-long diamond-shaped barbed arrow, which is mainly used for mid-to-close kills, with the arrow piercing at a distance of 70 meters.

Finally, there is a three-edged heavy arrow weighing 80 centimeters in 85 grams, which completely penetrates the iron plate at a distance of 50 meters.

Li Xiang was basically satisfied with the test results, and ordered 50 straight bows of 30 kg and 40 kg on the spot, plus 1,500 arrows, and settled them with grain, dried fish and other materials. At present, the interior of Mingyue Village is mainly bartered, and the precious copper coins are only available in the public middle school, which are mainly used to purchase salt cloth and other materials from the outside.

"By the way, how much tension does a bow made of fine single cedar have? 50 kg? Li Xiang suddenly remembered that the best bow material does not need to separate the epidermis from the inner accumulation layer, and can be directly made into a straight bow, which is very similar to the British longbow.

This straight bow made of monolithic wood has a long life and is simple to use. To make it, you only need to simply bake* and then add bamboo slices, which is of course a rare material.

"It's 50 kilograms, little master, please wait a moment." Zhang Qingping asked his teenage son, who was very clever, to come into the house to get it, and soon after he took out a large bow 1.7 meters long.

The bow body is pale yellow, and the single fir and old bamboo pieces fit tightly together, and they are beautifully tied. The bow body is very heavy, almost eight catties.

"It's rare to have a good bow, and now only one is made, and the rest of the materials can be made into another 10." Zhang Qingping pulled the bow out, and Liu Susu was inadvertently teasing Zhang Zhanjun. But when he heard the voice, he immediately turned his head and watched Zhang Qingping's action of pulling the bow, and his eyes froze.

Zhang Qingping saw the suspicion in Liu Susu's eyes, and he was a little out of shape, and his eyes flickered. The honest carpenter didn't find it boring, and was ashamed that he didn't complete Li Xiang's entrustment.

"It is not difficult to find more than three years old bamboo, as long as the bowstring is good, the tension can be at least ten more kilograms, but the good fir is too difficult to find. The old man is incompetent, and he has not found a good way to combine the tendon and horn pieces with the bamboo and wood bow tire, which is really a shame for the little master. ”

Li Xiang didn't mean to blame the carpenter, after all, he was one of the most loyal craftsmen to himself. "Make all the remaining good materials into bows, hand them over to the village owner, and put them in the account of the youth camp." Li Xiang heard that the village soldiers would take action soon, so he decided to be bold and not let his father-in-law look down on him.

Li Xiang decided to give it a try and use the benefits to stimulate the craftsmen and let them take the initiative to solve technical problems. "Since it is so difficult to fit the tendon horn piece and the bamboo and wood bow tire, then notify the entire craftsman camp. As long as anyone can increase the pulling force of an ordinary straight bow to more than 50 kilograms, I will transfer my shares in the bow and crossbow workshop to him. "Unleashed a blockbuster*, leaving a few craftsmen stuck in place, Li Xiang and Liu Susu Shi Ran left.

On the way to the youth camp, Liu Susu came over with a mysterious face, completely forgetting that he was slighted by Li Xiang not long ago. "That Zhang Qingping is very extraordinary, he should be a sharpshooter." Liu Susu was very excited, as if she had discovered something amazing.

"Hehe, it's not strange that the archers make bows and arrows, right?"

"No, he must have killed quite a few people with his bow and arrows. This is an intuition, anyway, this Zhang Qingping has a story on him, and his martial arts may be outstanding. "Liu Susu's girl's nature is fully released, and the fire of gossip is burning.

"Everyone has a story, and since people don't want to tell it, don't force it. As long as he doesn't do anything unfavorable to Mingyue Village, he will ......"
