The making of a bow and arrow is actually very simple, and it is composed of three parts: the bow arm, the bowstring, and the arrow. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 info bow arm is the most complex. The production of the bow arm is also very simple, even if there is no retinal system, Yao Ran can study it himself. But with the retina system, of course, it is necessary to make use of it, which is simple, powerful, practical and easy to operate, and the retina system is given at the request of Yao Ran, a set of simple recurve bow production process.

The material is made of tough, straight-grained wood, or directly made of bamboo. Yao Ran chose bamboo, which was available nearby. Because there are other woods that can be made, but it takes too long. Yao Ran began to explain to the villagers around him while doing it: "The materials of the bow arm have to deal with a total of five parts, two bow arms, and one handle. The two bow arms use external forces such as fire roasting hand breaks to bend the joint, and the larger the arc, the better. Cut the trunking and wrap it tightly with hemp rope to fix it. The handle is also fixed at the junction of the two bow arms at the same time. Then bend the two bows in the same way, and wrap them with hemp rope. The bow arm of such a recurve bow was made. Yao Ran muttered as he did it. The work in my hands didn't stop.,I love to think that I also tried to open a live broadcast at the beginning.,What a game?,Handmade.,It's all broadcast but no one watches it.,I didn't expect there to be some feeling of live broadcast in this primitive meeting.。

The bow arm was roughly made around the campfire at night, and it took nearly three hours to make it. This is still not the case of the bowstring, the recurve bow, as the name suggests, reverse bending, the bending angle of each bow arm is about 45 degrees, according to the bowstring length given by the retinal system, the bending angle of each bow arm after the bowstring is put on should be about 30 degrees. That is, 45 degrees plus 30 degrees. This recurve foot can bend at an angle of 75 degrees. Yao Ran saw that the time was not early, so as not to affect everyone's only entertainment activity at night, it would affect the growth of the population. Yao Ran dispersed the crowd and began to make his own bowstring according to the production method given by the system. Hands-on little masters. Took a few tendons from unknown animals. Holding a very thin stone shard, scratching and drawing into a row. Each strip is controlled at three millimeters in thickness and more than one meter in length. In the end, the beast tendons with the thickness of the index finger were only cut out of three tendon threads to meet Yao Ran's needs. I cut four or five tendons to get nearly two dozen tendons. In a group of five threads, Yao Ran began to tightly wrap the torn animal tendon line with a braided thin rope, and the two ends of the tendon line were tied to two pieces of wood. One end was in Yao Ran's hands, and the other was under his feet. After being entangled all night, after dawn, Yao Ran held a recurve bow with a good bowstring in his arms, and there were a few straight bamboo sticks in front of him. Red and swollen eyes, called by teeth, to eat breakfast. After breakfast, Yao Ran went from house to house looking for someone to ask for feathers, and finally found more than a dozen feathers, during which he cried a few primitive beauties who loved beauty, so I won't talk much about it.

The production of arrows is simple, take a bamboo pole and split it into strips. To put it simply, just take a stone and smash the whole bamboo flat, and then take out the one that has not been broken, and grind out the cracks at both ends. At one end, two feathers are inserted symmetrically. Lock the back head with a thin rope and polish the tail, the front end is stuck in front with a selected, sharp and flat small stone, fixed on the crack with a rope, and after all are done, Yao Ran tried the bow several times in front of the tree by the river, and the poor big tree was pierced with a few holes. Yao Ran excitedly ran to the villagers who were logging wood. He called a few tree cutters and told them to go hunting with them. The insect also followed behind him with curiosity in his eyes, not knowing what the bow and arrow in Yao Ran's mouth was for, what the thin bamboo piece could be used for, and hunting? He didn't even take a wooden spear.

This recurve bow is much more powerful than the single wooden bow made by the earliest primitive people, and the windless recurve bow made by Yao Ran has a theoretical range of more than 200 meters, of course, this is not an effective range. As far as the accuracy of the current arrow feather is concerned, the effective range is only forty or fifty meters, the arrow is not straight enough to increase the resistance of flying in the air, and the stone of the arrow is not sharp enough, etc. In such a composite tool, every part is not an ornament, even the broken hemp rope hanging on the bow head is also an auxiliary tool to see the direction of the wind. The accuracy of the components plays a decisive role in the performance of long-range weapons.

Yao Ran and the others shuttled through the jungle, with five freshly made arrow feathers inserted in their backpacks. Hand-held recurve bow. After running for almost half an hour, Hua Tuo, who was sharp-eyed, squatted down and pointed not far in the direction of two o'clock in front of him. Yao Ran looked and saw a big bird like a peacock standing in the middle of a tree, Yao Ran took an arrow and bent a bow, this single dog in his previous life for many years, not a unicorn arm in vain. According to the anti-bending angle of the bow arm and the toughness of the bamboo, the strength of this bow is about 70 kilograms, and if it is replaced by a few stone bows in history, this bow and arrow is enough to have the power of two stones. The forest was quiet and windless, and the big bird must have seen Yao Ran, because there was an empty flat land all around. Hua Tuo, Worm and the others were still preparing to bend down and walk over slowly, using stones to hit the birds, when they heard the "bow and arrow" in Yao Ran's hand bang and shoot out with a bamboo pole. Yao Ran then pulled out an arrow feather from the backpack behind his back, and shot it out with a bang, the animal's instinct for danger is cultivated little by little, they know what range is dangerous, and in this ancient era, no animal knew that something could immediately threaten their life from dozens of meters away, so even if they saw Yao Ran and others, the big bird did not move, and when it heard a sound, it looked over and saw a branch inserted into the big tree under him, which frightened him, and hurriedly flapped his wings and prepared to fly away, but Yao Ran's second arrow feather, followed by the third arrow feather. Accurately shot the big bird, one of the arrow feathers because the arrow was not sharp enough or the angle was not right did not pierce the flesh, but the strong impact still gave the big bird a sad roar, followed by the third arrow feather into the body, the big bird stared at the eyes and didn't know how he was hit and fell under the tree, what flew so fast, died under the first bow and arrow, this big bird needs everyone to commemorate it.

Yao Ran staggered to the bottom of the tree and picked up the arrow feathers and prey. A group of primitives with a surprised face were left behind, standing in place dumbfounded. This distance can stick a small stone spear into a tree, and it can also stick a bird in a tree. That's amazing. Hua Tuo thought to himself that his "teacher" was a little too powerful. If he is so powerful, he must have many wives. And the worm did not hide the greed in his eyes, and he wanted to turn the bow and arrow into his own now.

Yao Ran walked back with the big bird on his shoulder. I saw the eagerness in the worm's eyes. One pushed the recurve into the worm's arms. Lost the big bird to Hua Tuo. He said, "Let's go, go back first, you find a tree to practice your head." This bow and arrow is not easy to come by, and it should not be easily discarded and damaged. "After biting the worm. Yao Ran strode in the direction of the village. Yao Ran no longer has to be like the first time he entered the primeval forest, he is afraid of petting beasts, afraid of getting lost, and has a retinal system, although there is no manual and system introduction, but Yao Ran himself feels that this thing is for the aliens who kidnapped him to use for emergency survival. It's a pity that what kind of target positioning system, global eye function, satellite guidance, etc., are all gray on the system page because they can't be realized without the assistance of the satellite. Yao Ran also used to be obscene in his heart, if all functions were fully open. It won't take 10 years to lead these primitive people into the industrial age. The wreckage of the ship is still embedded in the mountain. When your strength grows, you must dig that thing out. Whether it is for returning home or for technological progress, it should play a vital role.

This bow and arrow should be made in batches, and more people should be taught to make it together. The material is made locally, and bamboo can be used. Thin wire rope tendons are also in some stock. The finest work of cutting animal tendons is done by Yao Ran himself, and the other baking bends are fixed, and other work can be arranged for others to do it. The worm asked his wife, who had just given birth a few days ago, to help Yao Ran make bows and arrows. After arranging.

Yao Ran took Hua Tuo to the logging place to collect medicine.

What is the treatment of diarrhea, anti-inflammatory and swelling, and hemostasis. Anesthetic for pain relief. Looking at the mountains all over the field, Yao Ran took the trouble to dictate the explanation of what he saw in the system to Hua Tuo. After walking for nearly an afternoon, the three baskets prepared by Yao Ran were already filled with all kinds of herbs. It is mainly based on hemostatic herbs and anti-inflammatory herbs. There are also adjuvants that can be used together to enhance the efficacy of the drug.

After returning to the village, he took out the herbs and began to test Hua Tuo's understanding and memory in the same way. Hua Tuo really likes and loves to treat diseases and save people. So I basically remembered what Yao Ran said in the afternoon, and almost didn't make any mistakes. But Yao Ran still reprimanded Hua Tuo. and told Hua Tuo, "Treating diseases and saving people is related to life and death, and there must be no carelessness." Otherwise, they will harm others and themselves. Seeing Hua Tuo's well-behaved and obedient appearance, Yao Ran was very satisfied. Thinking that in the future, not only should Hua Tuo treat diseases and save people, but also open a hospital, teach a medical system, and improve the life expectancy of primitive people, and at the same time increase the number of people in disguise.

All kinds of preparations for long-distance migration are being carried out in an orderly manner. More and more stockpiled supplies were piled up behind Yao Ran's tent. The wisdom of the working people is infinite, the hat by the branch, the lid of the pot, the lid of the basket. It was also made by ingenious people without Yao Ran's guidance. Yao Ran looked at the basket full of cured meat, pickled fish, bacon, and smoked fish in front of him with relief. There are also some fruits, and Yao Ran pointed out that there are several kinds of greens that can be eaten.

When the block was daytime today, Lang Mao took someone to make another one. The block made by Lang Mao is larger than yesterday's, but the gap space between the chassis wood is large, Yao Ran tried it himself, and there is no problem with using it, and it can be used completely. The ropes that the women kneaded also had a lot of bundles rubbed. After weaving straw shoes and frames to make a pulley, there are nearly 300 meters of rope left. There is also a thin rope that Yao Ran wants is more than 100 meters. More than 100 pairs of straw sandals were braided. Almost everyone had shoes to wear, but only about 50 baskets were braided, because the suitable branches in the vicinity had been broken, and it was not safe and convenient to transport them further away. Everything that could be put in the basket, and finally added the herbs picked by Yao Ran, and the thirty or so baskets basically packed all the scattered materials. As for living in the wild, there are many things you need to easily set up a tent. The cloth and animal skins on the outside of the tent are definitely not enough, and it is necessary to weave mats from hay leaves. A tent needs four mats, two large sides on both sides need about 4 to 6 meters, the left and right two small sides also need about 2 meters, and a tent in the Yangtze River Delta also needs at least 6 fine logs. In order to reduce the weight and look neat, they were all skinned, which was a large number of materials that needed to be pulled by a heavy vehicle such as a pulley. There are 24 families in the whole team, including Yao Ran and Ya, there are 25 families, and there are as many as 25 tents, each of which needs 6 pieces of wood, each of which is nearly three meters long. A minimum of 150 pieces of wood is required. These 150 logs basically filled a pulley, and there was nothing else to put on the pulley, and the wood was still very heavy. It takes at least four people to pull away stably, and two can barely pull but it is more laborious and not suitable for long-distance travel. There is no way to carry these necessities, but they must be carried. A team of more than 100 people can't go and live in a cave every day. It seems that there is still a need to continue to prepare supplies......
