back to ancient times to be emperor

Chapter 117

Shen Kuo was also confused. It is clearly recorded in the classics that the Qin Dynasty stipulated that "cars on the same track" stipulated that the distance between the two wheels on the car should be changed to six feet, so that the distance between the wheels would be the same.Why did the student say that the roads he had seen were not so wide at all?Who is wrong, are the classics wrong, or is the student lying?
Su Song is also a very rigorous person. He carefully studied the historical records of the Qin Dynasty and found that the Qin carriage was very distinctive.There is a door at the back of the compartment, and three windows on the left, right and front.The front window panel is a hollow diamond pattern, and the window panel can be opened to facilitate the exchange of information between the owner and the royal hand.The windows on both sides can be pushed and pulled back and forth, and the window panels are also hollowed out with diamond patterns. From the indoors, the situation outside the car can be observed, but it is difficult for people outside to see clearly inside the car.Rising above the horse's head are the poles, which support the shaft and relieve the horse of stress during long breaks.An iron ring is added to the axle to make the iron grind against the iron, and grease is added to lubricate it, which enhances the firmness of the wheel and reduces the friction of the car bearing.Some of the wheels were made of hardwood, and some were made of iron.

Qin carriages are mostly two-wheeled vehicles, and their designs vary according to different purposes. Some are suitable for carrying heavy loads, some are good for speed, and some are light and comfortable.What I just mentioned is a carriage with an open top, which is in a convex shape, divided into front and rear rooms, and has a dome-shaped oval cover on the carriage.Some are "vertical carts", which are two-wheeled carts with a single shaft and a round umbrella on the cart.

Tang Xun didn't understand carpentry, so he could only stare aside, watching Shen Kuo and Su Song having fun.The power of ancient carpenters is beyond the imagination of ordinary people. Many epoch-making inventions almost all appeared in the form of carpentry first.Such as gears, the clever Chinese invented wooden gears very early and used them in many places.Since the Eastern Han Dynasty, gears with different shapes and purposes have been widely used in equipment such as water-turning continuous grinding, guide carts, and drum carts.There are also tangerine and potter's wheels that use the principle of leverage (both are tools used to draw water from wells, and are still used in some northern rural areas), as well as plowing carts, irrigation dumpers, and bobbins. These need not be introduced. , Some rural villages are still preserved in later generations.

In addition to these, there are also fan carts for threshing (driven by human power, mainly used to remove chaff from grain particles.); water reels for pounding rice with hydraulic power; hydraulic blowers for iron smelting, which are driven by horizontal or vertical water wheels. The mechanical device of leather bag or wooden fan blowing air is now also used by the Suburbs of Chang’an Military Supervision to supply air to the blast furnace with this hydraulic blower; there is also a wooden bellows, but it has not been invented in this different time and space, and it is still used to rotate by water. fan.These instruments are extremely ingenious, and the wisdom of ancient carpenters can be seen.What's more, it is said that Zhuge Liang invented the wooden cow and horse, and Gongshuban invented the wooden plane, which flew for three days and three nights without landing. These are all like myths in Lu Chengqi's view, and I don't know if they are true or not.It is an indisputable fact that the wisdom of the ancients is not inferior to that of later generations.Although they don't know the principles, they are already using these principles to create amazing and ingenious devices one after another.

Qin Chidao is not like this!Such ingenuity made even Lu Chengqi from later generations amazed.It's no wonder that he attaches so much importance to craftsmen, since he was awarded the subject of Chi Dao, he has been running to the Royal University from time to time.

Just when Shen Kuo and Su Song were puzzled, Lu Chengqi once again came to the Royal University to study Qin Chidao with them.Hearing Shen Kuo's confusion, Lu Chengqi thought about it for a while, and then he knew the problem.Although Shen Kuo and the others are smart, they are easy to get into a dead end, and it is easy to fail to get out.They didn't expect that there was any difference between the six feet of the Qin Dynasty and the six feet of the Dashun Dynasty.One foot in Qin Dynasty was about 23 centimeters in later generations, and one foot in Dashun Dynasty was about 32 centimeters in later generations.There is almost ten centimeters difference in the middle, how can it be the same?
After Lu Chengqi said this, Shen Kuo and the others suddenly realized, and said: "I never thought that Qin Liuchi is different from today's Liuchi. If His Majesty hadn't woken up, the ministers still couldn't figure it out. I am really ashamed."

Lu Chengqi sighed: "You are too limited to the technology of the Qin Dynasty. In the Qin Dynasty, a lot of bronze weapons were used, but now iron weapons are used a lot. Qin Chidao uses hardwood rails, why can't we use steel to cast them? Orbit? What the ancestors can think of, the future generations should be able to imagine. I just want the effect of the way, as for the form, why do you stick to the way of the Qin Dynasty?"

Lu Chengqi's words were deafening, awakening Shen Kuo and Su Song who were still immersed in the world of the ancients.They said with shame: "Your Majesty's words awakened the dreamer, I am really ashamed."

Lu Chengqi added: "Tang Qing is an expert in smelting steel. The three of you should work together and listen to the opinions of these students. What can be made behind closed doors? Although these students are not as knowledgeable as you, but Three generals are better than one Zhuge Liang ("Cobbler" is actually a homonym of "Pi Jiang", which means "deputy general" in ancient times. "Cobbler"), with so many people, there will always be an idea."

The three nodded, and Lu Chengqi continued: "If the steel is not enough, you can try to build a section first; if you don't have enough horses, you can go to the horse herding supervisor to get the horses, or even come and tell me that I will allow you to go to the horse supervisor to choose horses. "

Tang Xun suddenly asked: "Your Majesty, since the carriages are all made of steel, are the carriages also made of iron?"

Lu Chengqi thought for a long time before he said: "Easy parts such as wheels and axles can be made of iron. However, durable parts such as carriages can be made of wood. The imperial court is not very rich in money and cannot afford such consumption." .In addition, the steel produced by the blast furnace is not very much. Good steel should be used on the blade. You understand this truth better than me. Although I don’t spare you money, I can’t waste it like this.”

Tang Xun nodded, expressing his understanding.Lu Chengqi continued: "The key is to study the distance between each sleeper in the gallop, and how to make the horses work hard and move forward at a fast speed, reaching a thousand miles in a day."

Shen Kuo and Su Song said in response: "Your Majesty is indeed a scholar of heaven and man!"

Lu Chengqi waved his hand and said, "I can only give you suggestions, but you have to present the finished product, otherwise I won't 'let it go'!" After speaking, Lu Chengqi himself laughed.

With this level of "threat", the three of them were really happy. They patted their chests and said: "Since your majesty does not follow the Qin system, it will be easy to handle things over there. I have confidence that within one month, the road and the carriage will be ready." , can do well!"

Lu Chengqi nodded, and said, "Since you are all so confident, I'll just wait and see."

These three are all scientific madmen. Now that they have a direction, the three of them immediately work together and cooperate with many students from the Royal University to study together.Tang Xun is the best in smelting, leading many blacksmith students to study the width of the track, the distance between sleepers, and how to stop the horses.

Both Shen Kuo and Su Song were proficient in carpentry, and they led their students who were carpenters to study the shape of the carriage, how to reduce resistance, and how to enter the fast lane...

Under the division of labor and cooperation, unlike the carriages and carriages of the Qin Dynasty, a plan was soon finalized, and plans were made to test build a section of carriages and a carriage.
