The guide car is a legendary artifact, according to legend, in the barbarian era, the Yellow Emperor and Chiyou fought, the fog was foggy, it was difficult to distinguish the direction, the Yellow Emperor ordered the craftsman to build the guide car, it was by relying on the guide car to guide the direction, the Yellow Emperor defeated Chiyou.

If it is a legend, there must be no physical objects and no drawings. Once in the court, Gao Tanglong, a regular attendant of the free horseman, openly declared that the guide car was a matter of nothingness, and it was just a myth and legend made up by the predecessors.

Ma Jun refuted it at the time, believing that the guide car was ingenious, but it was not impossible to build.

Qin Lang, the general of the cavalry, also sneered, your husband's name is Jun, the word Deheng, Jun is a model of the instrument, Heng can determine the weight of the item, if there is no certain standard for the weight of the item, can it be used as a model?

Because of this, several people argued inextricably, and they made trouble until Emperor Ming drove it. Cao Ei didn't see the real thing, so he naturally leaned towards Gao Tanglong and Cao Ei.

Ma Jundang said that he was willing to create a physical object to settle the controversy.

Later, Ma Jun devoted himself to research, studied hard, and finally used the structural principle of differential gears to manufacture a guide car. Facts speak louder than words, and Ma Jun slapped some ministers of the DPRK and China in the face with tangible results.

The guide car built by Ma Jun is exquisitely constructed, and no matter what the circumstances, the direction of the little wooden man's fingers on the car is southern, and it is always the same. The civil and military forces of the Manchu Dynasty were amazed, and since then the world has obeyed its ingenuity.

This is a difference.

The overturning car was invented as early as the end of the Eastern Han Dynasty, but its structure is bulky and the operation is complicated, so that the overturning car has not become a sharp tool for water conservancy and irrigation for a long time.

When Ma Jun was doing things in the court, he didn't have much money, so he opened a garden as a land and planted some grain and vegetables to supplement his family.

But Ma Jun's vegetable garden is a piece of high ground, although adjacent to Luoshui but can not be irrigated, so Ma Jun did the improvement of the overturn, made a keel waterwheel, according to the history books, Ma Jun's modified keel waterwheel body with three plates put together into a rectangular long groove, each end of the groove with a sprocket, with the keel leaf plate as a chain, through the long groove; The body is obliquely placed at the water's edge, the lower sprocket and part of the long groove are immersed in the water, and the sprocket on the shore is the driving wheel; The shaft of the driving wheel is longer, and there are four crutches at each end; The person leans on the shelf, steps on the crutch, drives the upper chain, scrapes the water along the trough and rises, discharges the water to the end of the trough, and then returns to the water along the top of the long trough. In this cycle, water is continuously brought to shore. Ma Jun's overturned, light and labor-saving, can let children run, "its ingenuity is a hundred times more than usual", Luoyang people compete to imitate, is widely used.

The keel waterwheel was still widely used in the countryside until the 20th century, and an invention could be applied for nearly 2,000 years, benefiting hundreds of millions of farmers.

This is a difference.

Once, someone presented a set of puppets to Emperor Ming, which was well-made and lifelike, but the only regret was that this set of puppets was dead and could not be moved.

Cao Rong then asked Ma Jun if there was a way to make this puppet move, and Ma Jun gave him a positive answer, Cao Rong was happy, and ordered Ma Jun to transform it.

Such a difficult task may be incredible, but the wooden man is originally dead, how can he move? Many ministers who were not on good terms with Ma Jun waited to see his jokes and wait for him to be condemned by the emperor.

But Ma Jun slapped everyone in the face again, and he successfully created the Water Turning Hundred Opera, he made the prime mover wheel out of wood, and pushed it by water power to rotate it through the transmission mechanism. In this way, all the furnishing wooden figures on the upper floor were moved. Some beat drums, some blew xiao, some danced, some played swords, some rode horses, some stood upside down on ropes, and there were hundreds of officials. And these wooden figures come and go freely, their movements are extremely complex, and the degree of ingenuity is incomparable to the original puppets.

Cao Rong was happy and gave Ma Jun a lot of rewards, which are three differences.

Ma Jun is far ahead of his ancestors in the field of mechanical invention, and the inventors of the same era, only Zhuge Liang, the prime minister of the Shu Han Dynasty, can be compared with him.

But what makes Cao Liang feel sad is that people in this era despise craftsmen very much, and the status of craftsmen is also extremely low.

Ma Jun has exquisite skills, but no one pays attention to him, and he is not in a position suitable for him, such as the Ministry of Industry, and all his talents have been wiped out.

Ma Jun's keel waterwheel and loom are inventions that benefit the public, while the guide car and the water transfer are ingenious, but they are just amusements to please the emperor, and they are hardly of much value for social progress.

Zhuge Liang of the same era can apply the invention and creation to the military, the wooden ox and the horse solve the problem of transporting grain in Shu, and the Zhuge crossbow is a big killer weapon that improves the combat ability of the Shu army, so that the Shu army, which is not superior in strength, has been able to maintain the momentum of the offensive.

The most famous achievement of Zhuge Repeater is the shooting of Zhang He, the general of Wei, which makes the name of Zhuge Repeater famous all over the world.

However, Ma Jun disagreed with this, the Wei army had captured the repeating crossbow, after Ma Jun saw it, he thought that although the Zhuge repeater was very exquisite, it was not perfect, and if he was allowed to improve it, it could increase the power by at least five times.

However, the rulers of Wei ignored Ma Jun's proposal, and in their eyes, these skills were nothing more than obscene skills, and it was impossible to influence the course of the war.

This cannot but be said to be a kind of sorrow for Ma Jun, who has the ability to be empty, but there is no place for it.

Therefore, Ma Jun also became disheartened, and before he had time to sixtieth birthday, he took the initiative to return to the countryside, and closed his door to thank customers, and did not interact with worldly people.

Only Fu Xuan is full of praise for Ma Jun's talent, and he has become one of the few people who can enter and leave Ma Jun Villa freely, so don't look at the age difference between Ma Jun and Fu Xuan, but they are a pair of close friends who have forgotten their years.

Although Cao Liang bowed down sincerely with an attitude, Ma Jun still had a cold face, and he looked like he was rejecting people thousands of miles away.

Fu Xuan hurriedly smiled and said to Ma Jun: "Cao Ziming is the Marquis of Gaoling Pavilion, the son of Cao Yan, the general of Xiaocai, and he has always admired Mr. ”

Ma Jun did not change his attitude because of Cao Liang's clan identity, but was even more disdainful, he ignored Cao Liang at all, but urged Fu Xuandao: "You ...... this side of the matter You don't care, just take the drawings and show them to the general, and then ...... It's the right thing. ”
