Online Games: Start as an Emperor

Regarding the compass, many talents in Chinese history have researched and invented it.

For example, the great inventor-Yan Su.

Yansu's guide cart was a two-wheeled cart with a single shaft and a wooden figure standing on the cart with arms stretched out to guide the guide.

In the car, in addition to the two casters that roll along the ground, there are 7 gears of different sizes.

《"History of the Song Dynasty·Yu Fu Zhi" records the diameter or circumference of these gears as well as the pitch and number of teeth of some of them. From the number of teeth, the number of rotations, and the purpose of ensuring the wooden guide, it can be seen that the ancients mastered the mechanical knowledge about gear matching and the method of controlling gear clutch.

The wheel rotates and drives the vertical gear attached to it, which in turn rotates the small flat wheel meshed with it, and the small flat wheel drives the central large flat wheel. The vertical axis of the guide wooden figure is installed in the center of the large flat wheel.

When the car turns, you only need to operate the clutch device on the car, that is, the bamboo rope, pulley and iron weight, to control the rotation of the large flat wheel, so that the direction of the wooden figure remains unchanged. For example, when the car turns right, its front axle will move in the same direction. To the right, the rear shaft must be to the left.

At this time, as long as the rope around the rear shaft of the pulley is lifted up, the left small flat wheel will fall and separate from the big flat wheel; at the same time, the right small flat wheel will rise to mesh with the big flat wheel, and the big flat wheel will reverse with the right small flat wheel.

Since the gears are properly matched, the turning arc of the wheels is the same as the reversing arc of the large flat wheel, so the direction of the wooden man remains unchanged.

Later, Wu Deren redesigned the compass car made by Yansu in view of the major shortcoming that the compass car made by Yansu could not turn sharp turns, otherwise the pointing would fail. The basic principle of Wu Deren's compass is the same as that of Yansu, but it is more complicated in terms of attached devices. His car has two levels: upper and lower.

In addition to the wooden guide on the upper level, there are also two turtles, four cranes and four boys surrounding the wooden figure. The 13 intermeshing gears on the upper level are designed for them. The gear device and structure of the lower layer are as mentioned above. It was he who invented the sheave clutch device to ensure that the car does not affect the direction of the wooden man when turning big corners.

In Chinese history, many people have studied and invented the compass.

Some succeeded.

But most still failed.

Some skilled craftsmen even take making a guide car as a challenge.

But few people can invent the compass of the Yellow Emperor's period.

The appearance of the compass also made Luban very excited.

This was an object from ancient times, and even he was very interested in it.

He wanted to understand the principle of the compass and then make other inventions.

So when Lu Ban knew that Lu Yan had a compass in his hand, he suddenly became excited.

He entered the palace overnight and called Lu Yan out of Zhang Lihua's arms.

Zhang Lihua is so angry.

You said it was easy for me. The emperor finally came to rest in my palace, but in the end, he was ruined by you.

Zhang Lihua groaned angrily.

Lu Yan was speechless. When was this? Is it because of an emergency?

Lu Yan didn't dare to be careless.

Hurry to meet Lu Ban.

But after knowing Lu Ban's intention, Lu Yan was speechless.

It turned out that I came here for the guide car.

Think of the role of a compass.

Lu Yan refused unceremoniously.

This compass is just such a piece, and it is so important that it can break military formations. It is too precious to let you study it.

When Lu Ban found out, he was immediately unhappy.

If you don't give me a guide, I won't leave.

Lu Ban is pestering Lu Yan. If I don't leave, you can't leave either.

Just stay here with Wei Chen.

Lu Yan is so angry.

This is not a rogue thing.

Lu Ban suddenly looked like a rogue, either you give the compass to Wei Chen, or you kill Wei Chen.

Or, Wei Chen is here to pester you, not letting you sleep or leaving.

Is Lu Yan willing to kill Lu Ban?

Of course I couldn't bear it.

This is the boss among all the scholars, the famous Wood Sage.

The ancestor of carpenters.

Holding the"Book of Lu Ban" among the Four Great Chinese Books》

《"The Book of Lu Ban" is a strange book about civil engineering, said to be written by the sage Lu Ban.

The first volume is about Taoism, and the second volume is about explanations and medical spells. However, except for medical spells, there are no clear practice methods for other spells, only spells and talismans.

It is said that to learn Lu Ban Shu, you need to"miss one skill". You can choose from widowers, widowers, solitaries, alone, and disabled people. You start choosing from the time of practice. Therefore,"Lu Ban Shu" gets another name.——《Missing a door".

There is also a legend about this.

Legend has it that Luban, the founder of Lu Ban, was drafted to work in the capital not long after his wedding. Because he missed his newlywed wife so much, he made a wooden kite. As long as a person rides on it and recites a few spells, the wooden kite can carry him flying. Go back to your home thousands of miles away and reunite with your wife.

His wife was particularly curious about this. Once, after the ancestor came home, she secretly rode a wooden kite and chanted the same mantra. The wooden kite flew into the sky and soared freely. The Patriarch's wife, who has always been living deep in the boudoir, feels very uncomfortable.

However, the good times did not last long. Just as the saying goes, there are unforeseen circumstances and people have misfortunes and misfortunes. At that time, the founder's wife was already pregnant. While flying in the air, she suddenly gave birth and blood flowed out.

However, the wooden kite was originally made by the Patriarch using a secret method. Once it was defiled, the magic power disappeared immediately, and the Patriarch's wife fell from the air and died together with the child in her belly.

Master Lu Ban, who knew this, regretted it so much that he cursed everyone in the world who studied"The Book of Lu Ban".
