The war on the frontier stopped, all parts of the country were stable, and the Ming Dynasty ushered in a rare period of peace.

The various departments are operating as usual, without the complicated political affairs of the past, Zhu Cihong can rarely take a few days off, do something he likes to do, and go to Kunning Palace to accompany his wife and children.

As soon as I stepped into the Kunning Gate, there was a burst of laughter in the square inside.

As soon as Zhu Cihong came in, his face trembled in an instant, and what caught his eye was a bicycle!

I saw Princess Zhu Yujiao of Kunxing riding a bicycle, spinning in circles on the square of Kunning Palace, accompanied by the sound of a lark.

Empress Xu Chenyun and several concubines were smiling and pointing on the imperial steps, obviously surprised.

"Your Majesty has arrived!"

With a shout, the concubines immediately straightened up and saluted seriously, like lazy students, it seemed that the head teacher was coming.

"Excuse me!"

Zhu Cihong walked over and said curiously: "Kunxing, who made this thing?" ”

"Brother Huang, this is a collaboration between Wang Zheng and Bo Jue of the Royal Academy of Sciences!"

Princess Kunxing drove all the way to Zhu Cihong's side, and replied with a smile.

She is not afraid of heaven and earth, whether it is Chongzhen or Zhu Cihong, they all love her very much, except for Queen Zhou, no one can do anything about her.

"Oh, it's the two of them, no wonder!"

Zhu Cihong remembered that he once drew a drawing of a book in the Royal Academy of Sciences, which included a drawing of a bicycle, and a brief introduction.

If you want to build a bicycle, it's actually not difficult, but if you want to build a practical bicycle, in this era, there is still a lot of difficulty, and tires are a big problem!

However, with Wang Zheng and Bo Jue, two well-known mechanical experts, joining forces, Zhu Cihong was not surprised at all to make this thing.

After all, these two are in charge of the steam engine project, and there is already a spectrum.

Wang Zheng and Sun Heding's father Sun Yuanhua are lifelong people, they have also worked together, Wang Zheng loved ancient tools and machinery in his early years, and developed hydropower, wind power and load machinery before becoming an official.

Moreover, as early as more than 20 years ago, Wang Zheng independently built a kind of bicycle, which was four-wheeled, and used the principle of self-striking bells, which was recorded in his book "Illustration of the New Making of Instruments".

Not to mention Bo Jue's ability, the artillery team mirror in the Shenwu Army was developed by him.

Today's Royal Academy of Sciences has gathered a large number of talents, from eighty years old to six or seven years old, and there are even a few guys with special functions.

For example, if a person with excellent ear power puts an official document next to his ear, he can directly distinguish the content inside with his ear without opening it, which is amazing.

Zhu Cihong looked at this bicycle, especially the tires, which were actually made of rubber!

He asked, "How did the two academicians get this thing?" ”

Princess Kunxing often travels to the Royal Academy of Sciences, and she has observed the whole process of building this bicycle and learned about it carefully.

She said with a smile: "This is the material selected by Academician Wang Zheng after many experiments, and it seems to have been found from Yunnan. ”

Zhu Cihong nodded secretly, the big guy is the big guy, and you can make a real guy by giving a reminder.

The history of the development of bicycles, in fact, is the history of the development of tires, which have gone through the process of solid and hollow.

Listening to Princess Kunxing's introduction, when Wang Zheng started to build this bicycle, he also designed solid tires, but it was very bumpy in the process of driving, and after using it for a long time, the buttocks were swollen, and it could not absorb shock at all.

Later, Bo Jue suggested using rubber from Yunnan, which is very soft, and made it into a water pipe to install on the bicycle.

However, while riding, the weight of the human body caused water in the water pipe to spray everywhere, and the experiment failed again.

In the end, the two bigwigs spent several months together, and after trial and error, they finally added the inflatable water pipe to the bike, and only then did they find that the shock absorption effect was very good......

Looking at this tire, Zhu Cihong fell into deep thought, since these rubbers can be used to carry people on bicycles, is there any technology to use them on gun trucks?

If the wheels of the artillery carriage are replaced with rubber, and the Wangu Road (cement road) currently built in various parts of the Ming Dynasty, in the event of a war, the mobility of the Shenwu Army should be greatly enhanced......

In his thoughts, he only heard Princess Kunxing say: "Brother Huang, if you like it, this car will be given to you!" ”

Zhu Cihong took the handlebar of the bicycle and said with a smile: "That feeling is good!" Let me try! ”

"Your Majesty, no!"

The concubines all spoke in unison.

Empress Xu Chenyun explained: "Your Majesty, this thing is like riding a horse, you need more practice to master it!" ”

Princess Kunxing also giggled: "Brother Huang, let's take the time to practice secretly, don't make the royal sisters-in-law laugh in public!" ”

"Who do you look down on?"

Zhu Cihong smiled, tucked his robe behind him, pushed the weak-looking bicycle and trotted a few steps, and then got on the bike in a backward position.

After pedaling a few times, the speed of the car took off suddenly, Zhu Cihong accelerated the drag racing car, turned corners, drifted, and showed off his driving skills to his heart's content......

The concubines had already opened their mouths in shock, feeling amazing.

Yang Guifei held her stomach and watched with a nymphomaniac on the side, why is her man so good!

Princess Kunxing muttered: "Why is the imperial brother so powerful, has he secretly learned?" ”

Zhu Cihong stopped after three laps on the Kunning Palace Square, not because he didn't want to continue pretending, but because he felt that the quality of this bicycle was not up to par, far less than that of later generations, and it would be a shame if it fell apart halfway.

It's better to accept it when you see it!

Pretending to be forced together, the most particular thing is to be steady!

If you pretend to be good, it's called bullshit! If you don't pretend well, you're stupid!

Princess Kunxing surrounded her and said, "Brother Huang, give this car a name!" ”

"Give a name......

Zhu Cihong thought for a moment, and suddenly had a flash of inspiration, and said, "It's called a Phoenix brand bicycle!" ”

"Why is it called Phoenix?" Princess Kunxing was puzzled.

Zhu Cihong explained casually: "The one who was named in the queen's Kunning Palace was ridden by me personally, what is it called if it is not called a phoenix?" ”

Phoenix Bicycle .......

Princess Kunxing muttered a few words, and the more she looked at it, the more she liked it.

Empress Xu Chenyun pulled Zhu Cihong aside and said softly: "Your Majesty, there is something going on with Kun Xing coming today." ”

"Oh? What's the matter? ”

"Because of the matter of the horse...... Xu Chenyun said a few words with a smile.

Zhu Cihong smiled, it was clear that this girl had something to ask for, no wonder so many imperial sisters-in-law were called to offer their courtesies today, and they also gave me bicycles.

It turned out that Princess Kunxing often ran to the Royal Academy of Sciences, and after a long time, she actually fell in love with a young man named Sun Yunqiu.

According to Zhu Cihong's understanding, this Sun Yunqiu is only one year older than himself, is an optical instrument manufacturer, in history he wrote a monograph "Mirror History", manufacturing more than 70 kinds of optical instruments, known as the "Ming Dynasty Science Giant".

Sun Yunqiu mastered the technology of "grinding pieces to light" at a young age, creatively grinding lenses with crystal materials, and according to the age and different diseases of patients with eye diseases, he can match glasses with his eyes, so that patients can be equipped with lenses suitable for their eyes, which is more awesome than the optometrists who used machines in later generations!

I heard that last year, I also created a pair of reading glasses for the emperor, and the effect is very good......

Glasses were available in the Yuan Dynasty, but they were very expensive and civilians could not afford them.

In the Ming Dynasty, glasses were still rare, but in the Tianqi and Chongzhen dynasties, Hangzhou, Zhejiang became the center of glasses making, and Sun Yunqiu's technology was learned there, and then continued to study.

Because Sun Yunqiu's "History of Mirrors" made the manufacture of glasses simple, the market was made according to law, and glasses became popular in the world, and the price of the original precious glasses fell sharply, each pair of silver was worth only five or six yuan, and ordinary people could afford to consume it.

On the basis of grinding convex lenses and concave lenses, Sun Yunqiu also used crystal stones to grind into various optical products such as storage eyepieces, kaleidoscopes, mandarin duck mirrors, magnifying glasses, illusion mirrors, night mirrors, and telescopes (telescopes).

When Zhu Cihong first knew about Sun Yunqiu, he thought about whether this kid could make a camera or something under his own prompting, so that his handsome self could have photos that would be passed down through the ages......
