Zhou Muwang, a Yanshi man, went hunting in the west and met a strange Yanshi man in a distant foreign land. Yanshi is the most magical mechanical engineer in ancient legends. He once gave Zhou Muwang a puppet better than modern robots. The puppets created by Yan are very cool, just like ordinary people. At first, Zhou Muwang thought it was just Yanshi's entourage. After Yan's explanation, this famous gentleman with strong divinity was also surprised. Puppets move forward, backward, forward and backward, all of which are similar to real people. He can sing as soon as he breaks his chin, and swing and dance when he moves his arm, which surprises the onlookers. Zhou Muwang looked interesting and enjoyable, and let his favorite watch it. At the end of the performance, the puppet winked at Zhou Muwang's favorite person, which made Zhou Muwang fly into a rage. He decided that this flexible guy was a real person and would execute Yan on the spot. Yan immediately opened the puppet and found that it was just a dead object composed of leather, wood, glue pigments and black, white, red and blue pigments. Zhou Muwang looked forward and found that the internal organs of the puppet were all there, while the bones and muscles, joints, fur, teeth and hair were all outside, but they were all fakes. Once combined, they are living puppets. If the servant's heart is removed, the puppet will not be able to speak. When the liver is removed, the eyes will be blind, and when the kidney is removed, you can't walk. Finally, Zhou Muwang was impressed by Yan's superb skills. The original text is recorded in Liezi Tang Wen: Zhou Muwang visited the hunting road in the western regions, and there was a worker named Yan. The advocators created by Yan's family are full of interest, singing harmony, hands and dancing, which are ever-changing, but they are to their liking. The king thought he was a real man, so he observed St. Gine. The word will end, and the initiator will blink to recruit the king's left and right concubines. Wang was furious and wanted to kill Yan. The Yan family is in awe, and the Lord will show the king separately, all of which are done by Fu Huige ... The invention of Yanshi, Jia Mu mentioned "organ art", and everyone will think of defeat and Mohism. In fact, as early as 600 years ago, in the ancient historical document Liezi, there was a "wooden armor technique" far more exquisite than "organ technique", which was recorded in detail. Zhou Muwang went hunting in Kunlun Mountain. On his way back, he met a mysterious craftsman-Yan. Yanshi side stood a corpse, all strange characters of wood color, Zhou Muwang asked who it was? Yan calmly replied: "This is not a real person, this is my grandmother Yiling." Zhou Muwang couldn't help being surprised. Looking closely, he found that this wooden armor man was so lifelike! No matter whether he enters, retreats, lifts and lowers his head, it seems that he is really a living person! Zhou Muwang asked him to sing, which is in full compliance with the law; Asking him to dance is also ever-changing Zhou Muwang was surprised and immediately called his concubines to watch his performance. At the end of the performance, the Jia artist blinked and seduced Zhou Muwang's beautiful mistress. Zhou Muwang was furious and scolded Yan: "I thought I was really a Woodenhead! It turns out that I'm just looking for a real person to put a wooden skin on, trying to cheat me with strange skills? " In order to dispel doubts, Yanshi dismantled the real people on the spot and let Zhou Muwang observe them carefully. Zhou Muwang found that it turned out that he was really made of wood, leather armor, latex paint and other materials, whether it was liver, gallbladder, heart, lung, spleen, kidney, intestine, stomach, bones and muscles, joints, fur, teeth, hair and so on. All of them are man-made. Yanshi put these parts together again, and Mujia people can really come back to life! Zhou Muwang couldn't help but admire and sigh at this moment: "It's incredible that artificial skills can reach the level of the creator of heaven and earth!" However, this vein of Yan's "wooden armor" was later lost to the world. With the passage of time, in the Warring States Period 600 years later, the contemporary "God of Craftsmen" was like a disaster. It had invented a "robot" that could walk and move and was controlled by a pivot, as well as various highly lethal mechanical weapons. Mozi, the father of Mohism, also invented a mechanism kite that could fly for three days and a mechanism house that could move freely. At that time, both of them thought that their technology had reached the highest level in the world. However, Bird Slip, the great disciple of Mohism, told two old gentlemen what he had heard about Yan's skill. They are ashamed and never dare to talk about the skills of "organ art" again ... Jia Mu art and organ art "Jia Mu art" are driven by magnetism and controlled by magnetic tenons, pursuing flexibility, lightness and vividness; "Organ art" is driven by animals and controlled by fulcrums. As a military tool of war, it pursues rigidity and ruthlessness. From the beginning, their temperament and ideas were very different.
