In the seventh year of the Great Ming Dynasty (1627 AD), Wang Zheng wrote the book "Illustrated Records of Strange Artifacts in the Far West" and began to publish it.

The first three parts are mainly to translate the scientific knowledge and application technology of Westerners, and the last part is Wang Zheng's own invention, mainly self-grinding, bicycles, wheel pots, and ploughing, etc., if they can be manufactured, they are the most advanced civilian scientific and technological achievements in this era.

However, the publication and distribution of the book "Illustrated Records of Strange Artifacts in the Far West" did not attract the attention and attention of the Ming elite, mainly for two reasons:

One is the elite class who have the right to speak in the Ming Dynasty, who have studied the books of sages since childhood, and cannot understand these scientific books at all, so they denounce them as "strange skills" and then reject them; The second is that Wang Zheng does not have sufficient funds and manpower, so he transforms these scientific and technological achievements into tangible items, so that the people of Daming can feel that scientific and technological achievements bring convenience to daily life.

Until Zhu Youzhen came across this book by chance.

The birth of any new thing is not smooth, Copernicus was burned alive by the church in the Roman square because of the preaching of the "heliocentric theory", the Ming Dynasty has always emphasized agriculture and suppressed business, ignoring Wang Zheng's book "Illustrated Records of Strange Instruments in the Far West", which is already a good result, if you get a "literary prison" or something, Wang Zheng can't find a place to wipe his tears.

Zhu Youzhen decided to help Wang Zheng, helping him is to help himself and help Daming.

After the Ming Dynasty established the Academy of Sciences, Zhu Youzhen first made Wang Zheng a vice president, and in the Academy of Sciences, he had enough time to conduct scientific research and perfect his scientific inventions.

Subsequently, in the third year of Chongzhen, Zhu Youzhen summoned Wang Zheng in the Qianqing Palace.

"The grass people see His Majesty." Under the guidance of the eunuch, Wang Zheng gave Zhu Youzhen a big gift.

"Wang Aiqing doesn't need to be polite, give a seat, and serve tea."

"Thank you." Wang Zheng stood helplessly in front of Zhu Youzhen, he didn't dare to ≦ dǐng≦diǎn≦ small ≦ on the solemn mahogany chair and said, .£.o∷s_(); sat down, passed the eunuch pointed to diǎn, and wiped the chair three times with a wide cloth sleeve, and then half of his buttocks sat down, he couldn't understand why Zhu Youzhen summoned him, a junior official who had already resigned.

Seeing that Wang Zheng was too restrained, Zhu Youzhen asked with a smile: "Wang Aiqing, how is the Daming Academy of Sciences?" Isn't the environment here more suitable for scientific research than being an official? ”

"陛xià......"

"Wang Aiqing doesn't need to be nervous, just say anything straight." Zhu Youzhen seemed to be coaxing the child, for fear that his words would be a little careless, scaring this scientific giant, in case his brain was scared out of the problem, it would be a loss to the Ming scientific community, but not light.

"Your Majesty, the grass people like their current job very much." Wang Zheng believes that although the current work is monotonous, there is no heavy interference in civil affairs.

Zhu Youzhen estimates that Wang Zheng is also looking at Wang Zheng's appearance, not like a person who is greedy for power at all, but more like a child who has broken into the scientific labyrinth, "Wang Aiqing, "Illustrated Records of Strange Artifacts in the Far West", is there any progress now?" ”

"Your Majesty knows this book of grass people?" Wang Zheng seemed to have met a bosom friend for a while, he looked at Zhu Youzhen fixedly, his breath became short, if Zhu Youzhen was not the emperor, he was afraid that he would rush up and call him a brother.

"Of course I know, if it weren't for this book, do you think you would be able to enter the Daming Academy?" Only then did Zhu Youzhen reveal his original intention.

Wang Zheng knew that Zhu Youzhen had always attached importance to the development of science, but he didn't expect Zhu Youzhen to be paying attention to himself, and he was ashamed: "Your Majesty, the grass people are stupid, and the Western strange artifacts contained in the book have not been carried forward in the Ming Dynasty, and even the utensils designed by the grass people themselves have not been actually manufactured." ”

If you haven't made a real thing, it's still in the theoretical stage, how do you know its advantages and disadvantages? How can the people of the Ming Dynasty enjoy the convenience brought by science? Zhu Youzhen was also a little ashamed, he had been concerned about the military and political reforms of the Ming Dynasty, but he neglected the development of the most important civilian science, "Wang Aiqing, I have read your "Illustrated Records of Strange Artifacts in the Far West", let's sum it up and see if we can make your strange weapons." ”

"Your Majesty, can you really make it?" Wang Zheng's eyes widened, as if Zhu Youzhen was telling a story about the Arabian Nights.

"What's the use of this book if it can't be made in real life? Is this scientific knowledge just on paper? Zhu Youzhen also ignored Wang Zheng's surprised look, "Westerners have learned this knowledge, but they have produced corresponding physical objects, which not only benefit the people, but also earn silver." ”

"Earn silver?" What Wang Zheng lacked was silver, and if there was silver, he would have tried to make these artifacts of his, "Your Majesty, these utensils, can Da Ming really be able to make them?" ”

"You have to try it to know, but some utensils can definitely be made," Zhu Youzhen spread out the "Illustrated Description of Strange Artifacts in the Far West", "My favorite is this bicycle, if you can really build a bicycle, then ordinary people can hurry, but it is much more convenient, Daming now has many cement roads, especially suitable for bicycles." ”

"Your Majesty, the grass people have tried to make it from wood, but they can't use it." Wang Zheng was a little disappointed, but in front of science and Zhu Youzhen, he didn't dare to lie.

"The wood is too bulky, so naturally it can't be made, and it needs to be made of steel in the future," Zhu Youzhen was not polite, "Wang Aiqing, your bicycle still needs to be improved." ”

"Improvements? Majesty, the grass people really don't know, how to improve? ”

Zhu Youzhen began to popularize scientific knowledge, "no kind of utensils is eternal, all utensils will be replaced by new utensils that continue to appear, just like bicycles, the original people travel, can only rely on carriages, even walking, once the bicycle comes out, the people will use a large number of bicycles, with the progress of science and technology, bicycles also need to be continuously improved, and will be replaced by other more advanced utensils in the future." ”

“……”

"So, I think there are a few things that need to be improved on the bike you've designed." In the face of science, Zhu Youzhen does not care about face.

"草民求陛xià refers to diǎn." Wang Zheng slightly diǎn head, he did not make a physical object that could be used, basically stayed at the point of talking on paper, naturally he did not know the excellent diǎn of the bicycle and the place that needed to be improved.

Zhu Youzhen was also not polite, "First of all, the front and rear wheels cannot be large in front and small, nor small in front and large, the former is more laborious, and the latter will reduce the speed of the bicycle." ”

"Your Majesty, should the front and rear wheels be the same size?" Wang Zheng is worthy of being engaged in mechanical research all year round, and Zhu Youzhen is thorough.

"It is precisely that the front and rear wheels are the same size, so as to maintain a balance between labor-saving and distance-saving, and the bicycle will have practical value, and when the conditions are available in the future, you can try to make some bicycles with different front and rear wheels, and then try whether they are convenient to use."

"陛xià, the grass people understand, if it weren't for the majesty xià refers to diǎn, the grass people don't know, and the majesty is really a genius." Wang Zheng saw that Zhu Youzhen was full of jargon, and had to be convinced by Zhu Youzhen.

Talented? Haha, in the era we live in, this is pediatrics, Zhu Youzhen laughed secretly, and he did not refute Wang Zheng's compliment, "Wang Aiqing, and this handlebar, you designed it in a straight line, if you use it, the cyclist has to lie on the bicycle with his arms outstretched, which is not comfortable, and he can't fully exert the strength of his waist and abdomen." ”

Wang Zheng carefully looked at the bicycle diagram he designed, and sure enough, as Zhu Youzhen said, the handlebar is too long, and the cyclist must hold both ends of the handlebar with both hands, must fully open his arms, and his upper body must lean forward. ”

"The handlebar is designed to be short, in principle, it is okay, but the bicycle has to carry the weight of a person, and sometimes the back bracket has to carry goods, so that the stability of the bicycle will not be enough, and don't forget, the bicycle only has two wheels." Zhu Youzhen felt that it was still a bit difficult to impart knowledge to this scientific giant.

Fortunately, Wang Zheng's spirit of research is good, "Then according to His Majesty, how should the handlebar be changed?" ”

Zhu Youzhen was silent, looking at Wang Zheng with a smile, hoping that he could come up with an improved method by himself.

Wang Zheng frowned, thought for a while, and finally shook his head, "Your Majesty, the grass people are stupid, and they can't think of a solution for a while, so I ask Your Majesty for advice." ”

"Haha, I have read this book many times, and every time I see the handlebars of this bicycle, I feel uncomfortable, and after many days of hard thinking, I think of a solution," Zhu Youzhen can only flicker when he can't explain the source of knowledge, "I think that the handlebar of the bicycle should not be made into a straight bar, but into an arc, and the two ends of the handlebars are bent backwards, so that the cyclist can easily get on both ends of the handlebars. ”

"Arc? Curved? Wang Zheng whispered, as if he didn't quite understand.

Zhu Youzhen couldn't do it, so he had to ask the eunuchs to take pen and paper and draw a picture of the handlebar on the paper.

"Huh? So that's the case? Only then did Wang Zheng understand, "The grass people are so confused, I can't even think of it, Your Majesty...... His Majesty is really a god and a man. ”

"Haha," Zhu Youzhen was still dumbfounded despite Wang Zheng, "and the middle of the front and back discs, there is no need to fill the copper rod, the brass texture is soft, and it will be easy to deform in the future, so you should use harder steel instead." ”

"Steel? Majesty, does Daming have such hard steel? Wang Zheng expressed his objection for the first time.

"Daming can produce this kind of steel, Wang Aiqing rest assured, isn't the barrel of the flintlock pistol hard steel? And the base of the artillery, also of this hard steel. ”

Zhu Youjian originally wanted to change the solid tires to hollow inflatables, but finally gave up, and now there is no rubber and cannot be made into inner tubes.

Of course, Wang Zheng could not produce this kind of improved bicycle, so Zhu Youzhen handed over the production task to the Firearms Bureau, and asked the craftsmen of the Firearms Bureau to produce a batch of bicycles according to the drawings, and then improve the bicycles according to the actual use.

It took more than a year for the Firearms Bureau to produce a batch of bicycles that could be used in real life.

In order to highlight the mysterious effect, Zhu Youzhen ordered the Ouchi guards to secretly learn to ride bicycles.

Bicycle riding skills are very easy to master, if the training method is appropriate, you can master the performance of the bicycle in half a day, you can test ride independently in three days, if you want to fully master the technology of cycling, you can freely exercise and load on the cement road, it is only ten days and a half months.
