Since there is no chance to appear in the borehole fire cap gun, other new gun types with awesome design concepts, such as breeze fire cap guns, hand-cranked continuous shooting guns, etc., there is no need to show them out.

Zhao Shizhen planned to take Zhao Hao to the artillery workshop to see his latest design of steel cannons, but he saw a young man, aged 16 or 17, running along the cement road in a wheelchair.

As soon as this guy appeared, he became the focus of everyone's attention.

After being stunned for a second, the guards quickly stopped him outside the cordon. After checking the ID, they focused on the car.

The car was not very accurate for a wheelchair, but it was actually more like a four-wheeler that Zhuge Liang was riding on. The same wooden seat-like body has two small wheels in the front and two large wheels in the back.

The difference is that the four wheels are made of iron rims and solid rubber tires, and they can be driven by themselves without anyone pushing them.

The guards were very careful about the vehicle inspection and the young man was impatient for waiting, so they got out of the car and trotted over.

"Liangfu, why don't you prepare well? Why are you here to do it?" Zhao Shizhen glared at the young man with a beard.

"Senior brother, you are so embarrassed to say that we can't wait for the master to come. It turns out that you were abducted by you!" The young man was tall, with wide shoulders and wide waist, his eyes were circling, and his whole body was full of vitality and cleverness.

As he said that, he ran to Zhao Hao and said with a smile: "Let's go, Master, you are here to see us today!"

"First, I'm not old." Zhao Hao knocked on his head and said, "Second, are you ready?"

"I've been ready for a long time, I've been waiting all night." The young man patted his chest hard and said, "It's safe!"

"Okay, go to your place!" Zhao Hao nodded with a smile and said to Zhao Shizhen: "When the matter is over there, I will come to see you for a fuck."

"Oh." The eldest nephew nodded helplessly.

Zhao Hao couldn't bear to come and hit him, so he lowered his voice and said, "Actually, the mercury has not completely disappeared."

"Oh?" Zhao Shizhen was shocked and said happily: "Thunder Mercury?"

Zhao Hao sighed, "That can be safer."

After saying that, he walked towards the four-wheeler that had been inspected and asked the boy, "Is this your mount?"

"Yes, this place is too big and I can't raise horses, so I got a bicycle to drive it." The young man said proudly: "Master, what do you think?"

"Good guy, bike..." Zhao Hao touched his nose, but he had never mentioned these three words.

He looked at the transmission device of the four-wheeler with interest.

The young man introduced it from the side, and soon Zhao Hao understood the principle of the car - it also had a crank on the axle of the rear wheel, and used a connecting rod to connect the crank and the pedals under the seat. In this way, people sat on the chair and stepped on the pedals alternately, and the crank would rotate around the axis, causing the wheel to roll forward.

The two small wheels in front are connected to the handrail-shaped handlebars, responsible for steering.

"Not bad." Zhao Hao was very happy. He was worthy of being a disciple he valued, and it was very reliable to do whatever he wanted.

"Master, do you want to give it a try? It's so fun." The young man patted the seat covered with bamboo cushions.

"Liangfu, don't mess around!" Zhang Jian, who had been doting on his face, said furiously when he heard this: "What if he hurts his master?!"

"I understand, uncle." The young man shrank his neck and did not dare to instigate Zhao Hao any more.

"It's not hard, ride it." Zhao Hao saw Lie Xinxie, sat on and tried it. Except for the difficulty at the beginning, it was very light after kicking it up.

The four-wheeled bicycle whizzed forward, and everyone hurriedly followed behind, but was still pulled away.

"How do you brake?" Seeing that the road ahead was over, Zhao Hao suddenly remembered an important question and asked loudly behind him.

"Foot brake!" the young man hurriedly replied loudly.

Zhao Hao quickly looked down and saw two pedals, no other devices were seen.

"Where is the foot brake?"

"Just use your foot to brake!"

"What are you doing?" Zhao Hao moaned, leaned his back on the chair, and rubbed his feet on the ground, then he barely stopped the car.

But even if you can't stop, you won't hit the wall, because the guards of the security department have jumped off the wall and are ready to be a meat shield for him...

"Master, are you okay?" The young disciple followed and chased after him, his face turned pale because of fear.

"Fortunately, your brake method is quite unique." Zhao Hao rubbed Microsoft's knees and said lightly.

"The main reason is that the front wheel of this car is too small and the rear wheel is too large. Braking in this way can prevent forward leaning." The young disciple quickly rubbed his legs and said.

"It's just a waste of shoes." Zhao Hao blew his head hard, and the master and apprentice laughed loudly.

I have to say that the age difference between the master and the apprentice has finally become normal, and the picture looks much more harmonious...

~~

The young man called Zhang Jian an uncle, but he also called Zhao Hao an master with Zhang Jian. His identity was about to emerge - he was Zhang Jian's nephew, Wang Zheng, the son of Wang Yingxuan, the director of the 01st Institute!

Speaking of which, Wang Ying chose this missed scholar, and the teacher who could come from Shaanxi to Jiangnan was all thanks to his son for his blessing.

Although Wang Zheng was not born at that time, Mr. Zhao's great prophecy had already concluded that he would be a rare genius when he grew up, but he was the successor of his own robe... Of course, Zhao Hao had never told anyone about this. Others thought that he valued Wang Yingxuan's family because he loved Zhang Jian's house and Wu.

Zhang Jian has always felt that his master's great kindness has not been able to repay him.

In fact, even if Zhao Hao loves the house and the U, it is because he loves Wang Zheng... He is the most talented scientist and inventor in the Ming Dynasty!

In another time and space, Wang Zheng and Xu Guangqi were called "King of Southern Xu and Northern" together, and were the most outstanding pair of scientists in the Ming Dynasty. Both of them were extremely talented, had a wide range of knowledge, were well-versed in Chinese and Western cultures, and had extraordinary achievements.

If he had to distinguish between the two, Wang Zheng was still stronger than Xu Guangqi because he had a background in science. His father was good at mathematics, and his uncle was even more familiar with machinery and instruments. He laid a solid mathematical foundation since childhood with his elders, and liked to study machine structure, and was obsessed with inventions and creations... Since childhood, he "sleeped in thinking, and focused on the instruments that have never been seen in ancient and modern times."

Before he came into contact with Western learning, he was an excellent mathematician and inventor. Moreover, under the influence of his father, Wang Zheng specially developed various hydraulic, wind and load-loading machinery with the focus on "benefiting people's livelihood and daily use", which benefited the villagers a lot. Wang Zheng's name has also spread throughout Guanzhong.

Later, Wang Zheng came into contact with Western scientific books brought by Jesuit missionaries and realized that the mechanical technology in Europe was far beyond the Ming Dynasty at that time.

The worried Wang Zheng wanted to ask the missionary to help translate the materials into Chinese and spread them in the Ming Dynasty. But the other party told him that to make these machines, he must first learn theoretical knowledge, otherwise he would not be able to understand the principles. So under the guidance of the other party, he learned and mastered European geometry, mathematics and mechanics.

Then, based on three of Europe's latest scientific and technological masterpieces - General Theory of Mathematics, Complete Book of Mining and "On Various Craftsmanship Machinery", he compiled a book called "Archive of the Far West" based on three latest European masterpieces - "General Theory of Mathematics", "Complete Book of Mining" and "On Various Craftsmanship Machinery". The book is divided into four volumes:

The first volume is the "Introduction", which introduces the basic knowledge and principles of mechanics, and discusses gravity, the center of gravity of various geometric figures, the specific gravity of various objects, etc., and introduces the Archimedes' buoyancy principle.

The second volume is called "Archive Solution", which tells the principles of various simple machinery, such as balances, levers, pulleys, roulettes, spirals and inclines;

These two volumes are the first half and are the first step in physics work in modern China.

The lower part is the specific application.

The third volume is "Application of Mechanical Principles". There are 54 pictures drawn in total, all of which are the most advanced practical machinery in European countries. They include lifting, transportation, water withdrawal, pounding rice, and detaching wood, which are all beneficial to people's livelihood.

The fourth volume is "Newly made artifacts" and contains nine tools. It is a new type of machinery developed by Wang Zheng based on the above learnings. It is all practical inventions that conform to the principles of physics, rather than the simple whimsical thoughts of the scholars and officials.

For example, the 'siphon' is a machine that draws water from a low place to a high place; the 'Crane Induction' is used to irrigate the farmland; there are also the 'self-grinding' that drives the millstone with wind, the 'wheel pot' of the time-reporting machine, and the 'bike' used for transportation...

After the rest of his life, he continued to research various machinery, such as clocks, oil presses, printing machines, hydraulic spinning wheels, etc., basically, relying on his own efforts, he caught up with the mechanical gap between the Ming and Europe.

However, the Ming Dynasty was already terminally ill, and Wang Zheng had no chance to carry forward his own learning and inventions, and the country was at its end...

In October of the 16th year of Chongzhen, Li Zicheng captured Xi'an. Wang Zheng, who was already 73 years old, heard that Li Chuang wanted to come out to be an official, so he wrote a tombstone on his own:

"There is a Ming Jinshi Fengzheng official, a deputy chief of Shandong Censors, who was ordered to supervise the tomb of the Liaohai military service Wang Zheng, and then he failed to commit suicide, and then died on a hunger strike for seven days.

At that time, Zhao Hao was reading history here and closed the book and sighed. Another minister who was not worthy of the Ming Dynasty.

~~

It is precisely because of his appreciation of Wang Zheng's talent, ambition and personality that Zhao Hao is full of confidence in Wang Yingxuan, who gave birth to him and his uncle Zhang Jian. Without the influence of good family education, Wang Zheng would not be able to become Wang Zheng...

That's why Zhao Hao left himself to the most precious asset of the future generation - Xishan Island Research Center, and handed over it to Zhang Jianlai to take charge. He also entrusted important tasks to Wang Yingxuan.

But when Wang Yingxuan was brought to Suzhou, his wife was just pregnant... Zhao Hao was really worried for several years, fearing that Wang Zheng, who was born, would not be the one he wanted.

Fortunately, this child showed excellent talent when he was 4 years old. He could easily disassemble and assemble various exquisite toys given to him by Zhao Hao, and could recombine them to create new tricks.

When he was seven years old, he was taken under his sect by Zhao Hao. However, Zhao Hao didn't even have the time to teach his son, so of course he couldn't teach him personally, so he asked Zhang Jian to teach his master. He was not worried about misleading his children.

Wang Zheng did not disappoint Zhao Hao. Under Zhang Jian's guidance, he learned the mathematics, physics and chemistry knowledge passed down by Zhao Hao over the years at the age of twelve. He then studied with several other senior brothers for three years. He officially started his studies at the age of 15. He was directly thrown into the newly established "Tao Law Research Institute" by Zhao Hao.
