After leaving the Liuli area, Yan Changqing led the princes Zhu Biao, Zhu Xi, Zhu Fan, Zhu Di and other princes to continue deeper.
In the process of going deeper, the princes Zhu Biao, Zhu Di, Zhu Fan, Zhu Di and other princes also discovered that there were more and more soldiers patrolling and guarding around them.
This also shows that the further back the area is, the more important it is.
When everyone walked to the outer wall that separated the glazed area from the sea salt-drying area, Prince Zhu Biao, Zhu Di, Zhu Fan, Zhu Di and other princes looked up and saw a group of people standing on top of the high outer wall. A reflective glass mirror one foot wide, one foot long and one foot high.
The wide reflective glass mirrors reflect dazzling light under the sunlight.
Then everyone stepped onto the other side of the outer wall. As soon as they entered, there was what looked like a carriage, but there were no horses in front.
Instead, there were four strange things with two wheels fixed in front, and then a strange thing with a carriage without a roof behind it, parked at the door and waited.
In addition, five large, two small, and seven strange things with two wheels were also parked at the gate of the wall, waiting.
"Your Highnesses, please get on the bicycle carriage. Xiongying, Jixi, His Highness King Zhou, Duke Xin and I will ride bicycles."
While Yan Changqing skillfully sat on his exclusive bicycle, he turned to look at Prince Zhu Biao, Zhu Di, Zhu Fan, Zhu Di and other princes and said.
Behind Yan Changqing, Zhu Xiongying, Zhu Jixi, Zhou Wang Zhuji, Xin Guogong Tang He, imperial physician Wang Lu, and Haizhou City magistrate all sat on their own custom-made boats skillfully.
In the past year, they have been riding bicycles a lot, and none of them are said to have superb riding skills, but at least they have no problems with normal daily riding.
King Zhu Zhen of Chu looked at Yan Changqing and others sitting astride the thing with two wooden wheels, and said with a dumbfounded expression:
"What is this?!!"
Chu King Zhu Zhen suddenly discovered that in this Haizhou City, especially in this controlled area, objects that he had never seen before could be seen anytime and anywhere.
"This is a bicycle I invented, which uses its own pedals as driving force."
“Then it is transmitted through cranks, sprockets, chains, flywheels, rear axles and other components, ultimately enabling the bicycle to keep moving forward.
Yan Changqing said calmly.
The earliest bicycle was invented in 1790.
The bicycles of this period were called "wooden horses" and "wheels". Their structure was very simple, consisting of two wooden wheels at the front and back, with a crossbeam connected in the middle and a bench mounted on it.
There is neither a driving device nor a steering device, and there is no transmission chain.
The cyclist relies on his feet to push hard on the ground to move forward. When changing direction, he can only get off and move the bike.
The bicycle of this period looked like a toy.
After 1816, the bicycle evolved for the first time, and a steering device was added to it based on the "Trojan wheel". However, when riding a bicycle, you still had to push on the ground with two feet to move forward.
The bicycles of this period look like Yan Changqing's walker for three-year-old children in the previous life.
After 1840, bicycles were further improved on the basis of the former.
A crank is installed on the axle of the rear wheel, and a connecting rod is used to connect the crank to the front pedal. Both the front and rear wheels are made of iron, the front wheel is large and the rear wheel is small.
Bicycles of this period finally allowed people to truly lift their feet off the ground, and the alternate stepping of their feet drove the wheels to move forward.
It was not until 1874 that the bicycle was further improved, adding a chain and sprocket, and using the rotation of the rear wheel to propel the bicycle forward.
The bicycles of this period can be said to be truly modern bicycles.
In 1886, the bicycle was further improved, and a new bicycle style was designed from the perspective of mechanics and kinematics.
Front forks and brakes were installed, and the front and rear wheels were the same size to maintain balance. A diamond-shaped frame was made of steel pipes, and rubber wheels were used for the first time.
It can be said that the bicycles of this period are basically the same models as those modern bicycles of Yan Changqing's previous life, except for differences in appearance and performance!!!
This kind of bicycle is also known as one of the most successful human-powered machines invented by mankind. It is also a relatively good means of transportation in the era when steam power and electric power were not available.
Therefore, after Yan Changqing discovered that the four major control areas were too large and lacked faster and more convenient transportation, he ordered bicycles hundreds of years in advance.
After all, a bicycle is just a type of human-powered machine, let alone a Yan Changqing.
Even the Ming craftsmen of this period could make a bicycle by themselves as long as they got a design drawing about a bicycle.
After all, the production of cranks, sprockets, chains, gears, flywheels, rear axles and other components involved in hand-made bicycles was not difficult for the Ming craftsmen of this period.
Moreover, Ming craftsmen were more sophisticated in research on gears, chain transmission, etc. than Yan Changqing imagined.
After all, common water conservancy facilities in ancient times, such as waterwheels, barrel wheels, etc., actually involve the use of principles and technologies such as gears and chain transmission.
So after Yan Changqing drew the drawings of the bicycle, and then roughly explained the principles of the bicycle to the craftsmen.
In less than three days, the world's first bicycle appeared in front of Yan Changqing.
It's just that there is currently no rubber in Daming, so it is impossible to make rubber tires.
The bicycles made by Yan Changqing are the same as the previous bicycles in other aspects, but in terms of wheels, they are still mainly made of wooden wheels.
As a result, the bicycle's shock absorbing effect is very poor, and it can only drive on flat roads such as cement roads.
Otherwise, if you drive on other roads, your buttocks will be swollen.
This can be regarded as one of the few shortcomings of the bicycles made by Yan Changqing.
However, the current ground in the controlled area is all cement road surface paved with cement.
So if you ride a bicycle in this area, you won't feel bumpy.
As for the vehicles used to transport Prince Zhu Biao, Zhu Xi, Zhu Fan, Zhu Di and other princes, they were actually multi-person bicycles, but a four-wheel carriage without a roof was connected to the back of the multi-person bicycle through beams.
This kind of multi-person bicycle is usually used to pull goods, and it can also be used to pull people. It is the third main means of transportation within the controlled area.
Prince Zhu Biao, Zhu Xi, Zhu Fan, Zhu Di and other princes did not understand what Yan Changqing meant by bicycle.
But as long as they know that this bicycle is another new invention of Yan Changqing, that will be fine.
So Prince Zhu Biao, Zhu Di, Zhu Fan, Zhu Di and other princes did not hesitate and went straight to the open carriage carriage behind the multi-person bicycle.
After Prince Zhu Biao, Zhu Di, Zhu Fan, Zhu Di and other princes stood up and stabilized the wooden handles of the handrails around the carriage (Wang Hao).
Four attendants came out from all around and sat on the multi-person bicycle seat in front.
Then he began to step on the pedals slowly, and then the multi-person bicycle slowly drove forward with the open carriage behind it.
At the same time, Yan Changqing, Zhu Xiongying, Zhu Jixi, Zhou Wang Zhuji, Xin Guogong Tang He, imperial physician Wang Lu, and Haizhou City magistrate also followed on their respective bicycles.
After the multi-person bicycles gradually moved forward quickly, and Yan Changqing and others quickly followed up on their bicycles.
Prince Zhu Biao, Zhu Xi, Zhu Fan, Zhu Di and other princes have just understood what a bicycle is.
It turns out that this car does not need horses or other livestock to pull it, it can move forward just by stepping on it!!!
No wonder it is called a bicycle, it is indeed a bicycle worthy of its name!!!
