After returning home, Han Yun did not go directly to the Zhenbei Army Camp. Instead, he took out some wood and iron blocks in the house, and then took out the rubber tree, took an ax and chisel, and started working hard.
Qi Xiaoyu opened his eyes curiously, watching Han Yun making wood and smelting iron, wondering what he was going to do.
Qi Xiaoyu was a good boy who asked questions when he didn't understand, so he directly asked Han Yun what he was doing.
Han Yun smiled slightly and said,
"Don't worry, you will know later. This is a gift for you and Xiao Yuxin."
"Gift?"
Hearing this, Qi Xiaoyu became even happier. He didn't even ask about the affairs of the Tang Sect and concentrated on squatting aside to watch Han Yun do his work.
Under the precise control of the master craftsman Han Yun, handlebars, seats, chains, frames, wheels, screws, nuts, purlins, bearings, wheels and other items were quickly created by him.
After all the parts are manufactured, the next step is to assemble them.
In the evening, two bicycles, one large and one small, appeared in the yard.
The handlebars, seats and tires are all made of rubber by Han Yun.
"Wow, what is this? It looks so exquisite. Can it sell goods?"
Qi Xiaoyu happily ran to the big bicycle, touched it and looked at it. It was very novel.
"This is called a bicycle. It's not for pulling goods. It's for you to ride forward. It's a means of transportation."
Han Yun smiled.
In fact, this thing was only given to Qi Xiaoyu by the way. It was mainly made for Xiao Yuxin. The little girl must like this kind of thing that can be ridden and run.
As for older girls like Qi Xiaoyu, they are much less attractive.
At this time, Xiao Yuxin came back with her schoolbag on her back. The child had just returned from school. Looking at his happy face, he knew that he must have learned a lot of knowledge and read a lot of books.
"Big brother!"
When Xiao Yuxin saw Han Yun, she immediately ran over excitedly.
The little guy immediately jumped into Han Yun's arms. After acting like a baby, he turned his attention to the bicycle next to him.
"Yeah? What is it?"
The little guy opened his cute big eyes and looked at Han Yun.
"This is a gift for you. Come on, let's go outside and I'll teach you how to ride it."
“Okay~~”
Xiao Yuxin saw this kind of thing for the first time. It was small and delicate, and she loved it very much.
Two girls, one big and one small, pushed two bicycles, one big and one small, towards the large open space outside the house.
When he arrived at the door, Han Yun asked a servant to go down the mountain and call Zhao Long over, asking him to bring a group of soldiers to pull the cart over.
Then, Han Yun took off his cloak, helped Qi Xiaoyu's bicycle, and said to Xiao Yuxin,
"Come on, get on top of your bike."
"good."
Xiao Yuxin followed Han Yun's example and sat on the seat with one foot on the ground.
"Then, step on this pedal with your feet and walk forward."
As soon as Han Yun pedaled, the bicycle moved forward.
Qi Xiaoyu looked on, his eyes shining, and he exclaimed that it was magical.
Xiao Yuxin also followed his example and walked forward. Before she could take two steps, she fell to the ground with a plop.
Han Yun laughed, handed the bicycle to Qi Xiaoyu, and asked them to study together.
Both girls were smart, and they learned it quickly. The two of them rode their bicycles in the open space like they were having fun.
Han Yun smiled slightly and felt happy from the bottom of his heart when he saw this scene.
What is the purpose of a man's hard work? Isn't it just to make his wife and children happy?
Uh... A married woman is also a wife, and a sister is also a child.
As the sun gradually set, Han Yun, who was enjoying the happiness of his family, saw Zhao Long and a group of cavalry riding on desert wolves on the mountain road.
Zhao Long rode Mo Lang and walked over in a leisurely manner. He knew that it was definitely not an urgent matter for the Marquis of Zhenbei to call him.
If it was an emergency, Zhenbei Hou would fly directly to him.
So I didn’t leave in a hurry.
After arriving at this large open space, Zhao Long and the group of soldiers saw the figures of a large group of people and a small group of people riding bicycles to have fun.
This is a novelty that they have never seen before. They don't understand why a frame with two wheels can not fall over and can carry people forward.
The more they looked at it, the more novel it became, and their steps couldn't help but slow down.
It wasn't until they were very close to the Zhenbei Hou Mansion that they noticed Han Yun standing at the door.
He immediately sped up and came over.
Good fellow, the Marquis personally greeted them at the door, how could they neglect it?
After quickly arriving in front of Han Yun, Zhao Long and others turned over and got off the wolf, hugged their hands and said,
"Greetings to the Marquis."
"Um."
Zhao Long couldn't help but cast his eyes towards the figure over there, and asked curiously,
"Master Marquis, did you get that... strange thing? Where did you get it?"
"I made it myself."
Han Yun smiled.
Zhao Long's eyes lit up when he heard this and said,
"It turns out that it is the technology of the Marquis. Then this thing can be mass-produced. If it is popularized in the army, it can be used by the soldiers. It can greatly speed up the march and save physical strength.
And I think this thing shouldn't weigh much. You can carry it over difficult roads, or you can use it to pull goods.
If it is to quickly support the battlefield, it can also work wonders."
Zhao Long is an army commander who is extremely sensitive to things that can help strengthen the army. He can discover many wonderful uses just by looking at a bicycle.
However, Han Yun shook his head and said,
"Forget it, its traveling speed is not as fast as that of the cavalry. It can't walk fast when it encounters bad roads. It can't haul goods as well as a horse or donkey cart. It can't carry a heavy load either. There are many weapons on a soldier, so it's difficult for him to run.
The most important thing is that it cannot be mass-produced. Manufacturing those parts requires high-precision machine tools and the cooperation of various mature industrial chains, which we do not have.
Those machine tools and factories require our country to have a complete industrial system. Before the arrival of the industrial revolution, these were all delusions.
When we have such an industry, bicycles like this will no longer be rare. By then we can produce steam engines and motorcycles, so what else will we need for bicycles?
Moreover, it is also very fragile and easy to break. It can easily break when riding on bumpy roads or being hit by enemies, and the gain outweighs the loss."
Zhao Long was confused by a lot of unfamiliar terms in Han Yun's mouth and didn't understand them at all, but he also understood what Han Yun meant, which was that this thing couldn't be mass-produced.
Something that cannot be mass-produced is just a toy no matter how good it is.
Han Yun actually thought about developing industry, but the development of industry is inseparable from steam engines. Dachuan is still a feudal society now, which is too primitive. It will be a long, long way to get to that point.
It doesn't mean that you can create something just by taking a big step.
If you take too long a step, it's easy to pull your balls.
