Tang Yu and Xiang Jincheng came back from Ningxianglou, and rushed to the Ministry of Industry with Feng and Cheng, the two heads of the Ministry of Industry, to visit Cui Minghan, the secretary of the Ministry of Industry, and Li Yong, the secretary of the Ministry of Industry.

Two adults were waiting in the office hall.

Lord Cui is dressed in a red robe, the crane is supplemented, and Lord Li is in a green robe, and the brocade chicken is supplemented. They all wore black yarns. The people entered the house and sat down in order. Master Cui straightened the jade belt and said: "A few days ago, you and others said that a strange chart appeared in the abandoned bell tower in the north of the city, and the Ministry of Engineering heard about it and sent someone to check it. After preliminary investigation, comparison, analysis, and calculation, a conclusion has been reached, and now Mr. Li will introduce it to you in detail......"

"After receiving the order, the Ministry of Industry immediately sent several capable personnel to the bell tower to draw graphics and record data. Li Yong took out a roll of paper, spread it on a few cases beside him, and said: "After we came back, we worked overtime for several days, working until the second half of the night almost every day, and calculated a rough prototype. It was thought that the diagram and the associated data should be used to create a large mechanical object......"

"Mechanical objects?"

Cheng Liangjia and the others listened to it, but they didn't know why.

Li Yong smiled and asked, "Have you ever heard of the 'Wooden Ox Flowing Horse'?"

Xiang Jincheng scratched his head and grinned: "I have heard storytelling, the story of the Three Kingdoms in the teahouse, transporting grain, not eating forage, running like flying, anyway, it is lively and good-looking?

Li Yong nodded, didn't refute, picked up the scroll of materials, glanced at it twice, and said, "Don't say anything else, everyone in Luban has always heard of it, the carpenter ancestor, a person from the Warring States Period." It is said that his craftsmanship is extremely superb, making a wooden bird, put it in the sky, and can fly for seven days and seven nights?"

"Isn't that a legend?" asked Feng Letai cautiously.

"No, not legend. ”

Li Yong interrupted Feng Zhutou's words and said, "Lu Ban's matter, because of its age, has no certificate to examine. But the matter of 'wooden cows and horses' is indeed well documented. It is said that the methods of its manufacture are all included in the "Book of Wuhou Qi", but unfortunately this book was later lost. ”

"Even if it is lost, how can it be documented?" Cheng Liangjia asked with a straight neck.

Li Yong shrugged his shoulders and looked a little excited: "This has to involve another strange person in the world, Guo Shoujing, a famous mathematician, astronomer, and water conservancy expert. He controlled his emotions, sighed, and said: "In the fourth year of Yuanrenzong's reign, he excavated an ancient tomb in Luzhou, Sichuan, and unearthed a large number of gold, silver, jade, and porcelain, and also dug up the Book of Wuhou Qi. The gold, silver and jewels were snatched up by the diggers, but this magnificent book was ignored and thrown aside. When Guo Shoujing was in the Three Gorges to control the water, after hearing about it, he immediately sent a flying horse to Shudi, and strictly ordered the local officials to quickly collect it, and carefully protect it and send it to Dadu. It's just that due to the age, serious weathering, and wanton destruction by tomb robbers, the "Book of Wuhou Qi" has been completely damaged when it was transported to the capital!"

"In Luo Guanzhong's "Romance of the Three Kingdoms", when it comes to wooden cows and flowing horses, why do you say it so much?" Xiang Jincheng grinned.

"The words of the novelist are not to be believed. ”

Li Yong smiled and said: "Besides, if you open "Three Kingdoms" and take a look, in the chapter of Muniu Liuma, the most detailed part written by Luo Guanzhong is the size of the production materials, what ribs are three feet five inches long, three inches wide, two inches and two minutes thick, and what front bar is one foot eight inches long, two inches wide, and one inch and five minutes thick. The front axle hole is divided into four inches and two inches in diameter. But when it comes to the specific joining and assembly, it is not clear. Only vague words can be obtained. This is exactly the part of the Book of Wuhou Qi that is missing......"

Tang Yu was itchy when he heard it, and couldn't help asking: "Master Li, what did Guo Shoujing do after he got the "Book of Wuhou Qi"?"

"Guo Shoujing is an extremely smart person with a lot of talent. Li Yong straightened up and said slowly: "He got this book, and he wanted to restore the 'wooden cow and flowing horse' and benefit the society." You think, if the Ministry of Industry has so many behemoths and walks on the ground with heavy loads, then the construction of river embankments, mountain roads, and mine digging can not only save manpower and material resources, but also reduce danger and avoid unnecessary casualties. He sighed twice, and then said: "However, when he got the Book of Wuhou Qi, he was already eighty-one years old, and his physical strength was not as good as before, and he studied day and night to make up for the shortcomings, which seriously damaged his health and eyesight. Only five years later, in the third year of Yuan Yingzong's reign, this famous figure who had served as the water supervisor of the capital, the Taishi Ling, and the director of the Tonghui River Caoyun, and the academician of the Zhaobunkan University Shizhi Taishi passed away. ”

"It's a shame. ”

Less than 40 years after Guo Shoujing's death, a riot of the Red Turban Army led by Han Shantong and Liu Futong broke out in Yingzhou, Anhui. The world has been in turmoil ever since. Zhang Shicheng occupied Gaoyou, Chen Youliang was in Hubei and Jiangxi, Fang Guozhen was entrenched in the southeast coastal area, and the former emperor Wu Wang obeyed the order and guarded the heavens, and the Great Yuan was divided. In such a chaotic era where smoke is everywhere, it is natural that there is no infrastructure to be built? So the descendants of the Guo family dragged the men and women out of the Yuan capital and returned to their hometown......

Feng Letai heard this, glanced at Li Yong seriously, and asked, "Where is the origin of this Guo family?"

"Xingtai, Hebei. ”

"Even if this person hiding in the bell tower to study the 'Wooden Ox Flowing Horse' is indeed a descendant of Guo Shoujing, he doesn't have to hide his head and tail. When Feng Letai heard this, he said: "He should apply to the Ministry of Industry, establish a project, be supported by the state financial allocation, and engage in scientific research in the name of righteousness, isn't it better to be sneaky?"

"Maybe there's something hidden here. ”

Cheng Liangjia was anxious, and after listening to it for a long time, he was impatient. He stood up, took out the leopard tendons from the "Huayu Xiaozhu" and Ning Xianglou from his sleeves, and presented them with both hands: "Two adults, what is the use of this?"

Li Yong received it, looked at it a few times, and then handed it to Master Cui: "This is a leopard tendon that has been anti-corrosive and specially processed, which is extremely tough, and can be attached to the wheels inside the mechanical body, and is used to drive the occlusion between two or more gears when rotating, so as to cause a chain reaction of the entire machinery." ”

"Master Li, we don't understand. ”

"The principle of machinery is actually the same as that of people. Li Yong was not bored and patiently explained: "For example, if a person wants to walk, he has to lift his hands and legs, to hold something, his arms have to be stretched out, and his five fingers have to be opened. It's just that controlling people's actions is people's autonomous consciousness, and machines rely on a series of drivers. In the Song Dynasty, the craftsmen in the workshop once made a wooden beauty, dressed in clothes, greased and powdered, and the interior was controlled by a large number of wheels and rubber bands......

"It's a pity. ”

Feng Letai sighed: "A person can develop such a strange play, it is simply a genius." Incredible. Did the descendants of the Guo family crack the incomplete "Book of Wuhou Qi"? Or did someone steal or use these techniques by force, and Li Dai was stiff and engaged in some illegal deeds behind the scenes?"

Cui Minghan glanced at everyone, then turned to look at Feng Zhutou, and said in a gentle tone: "Calculation drawings are our business, we should not let it go, and the judgment of chasing the murderer will belong to you Ying Tianfu - we are not good at this." ”
