It is a long-cherished wish of mankind to continuously expand the scope of activities.

When gathering food for a living, expanding the range of activities means more food sources, and having more food can develop one's own population and increase the chances of one's own race to reproduce.

Therefore, for this purpose, human beings have been constantly researching in order to run faster, to walk faster, and to be able to travel the farthest distance in the shortest time.

Due to the limitations of the human race itself, they were given the attention of animals, so they had mounts and animal carts, and all kinds of docile bipedal or quadruped dinosaurs, quadrupeds, land birds, etc., were tamed.

On rivers and oceans, people no longer swim and cross, and invent paddle boats, sailboats, etc., which can also go very far.

Even with the increasing "force value" of human beings, as well as the invention of high-altitude escape equipment, the target has begun to turn to large flying creatures.

But birds, due to their peculiarities, are not so easy to tame.

But no matter what, the range of activities is getting bigger and bigger.

For two thousand years, ships were very convenient, but they could only advance along the coast at sea, so in the main range of human activities, animal carts on land were absolutely dominant.

It's just that beasts are actually living organisms like humans, and they also face a variety of problems, such as food needs, physical limitations, illness and death, easy to be frightened, etc., so the cost of its use is quite high, ordinary civilians cannot afford it, and it is not particularly convenient.

It is the beast carts that I see in the city now, there are basically no civilians, they are not the private cars of large families, or they are owned by various chambers of commerce, and those who drive are just hired by them to work.

It wasn't until the invention of the steam engine, and immediately after the advent of the steam train, that it was much easier to travel between towns and cities along the railway.

Even the train has just appeared, and the cost of infrastructure is also a bit large, so the cost of using the train is not very low, but with the upgrading of technology, it will soon be close to the affordable range of civilians.

It's just that the train also has a problem, its activity is affected by the rails, and it can only be used for long distances between cities with rails, and it is still not usable in the city, and there is not much convenience in places far from the railway.

And the train is not a personal tool, there are only a few railways in total, and you can't use them anytime and anywhere you want, you can go wherever you want.

Because these people in the meeting knew these reasons, the head of the branch explained the technology of the bicycle and they immediately understood the benefits of such a bike.

"I just don't know if it's good to learn, if it's easy to learn, then this kind of car is simply born for convenient personal transportation in the city."

"That's right, most people still rely on walking now, which is very efficient, and if you have a bicycle, it's very different."

"This bicycle is good, not only can be used in the city, but also between towns and villages, as long as it is not too far away from the village, it can basically be done for a few hours round trip, which will greatly accelerate the communication between people, and the development of civilization is inseparable from the communication between people."

"That's right, you can go anywhere you can walk before, you can spend half or even a third of your time, and you can even expand your previous range of activities, which is very useful for a lot of people."

"I think this tricycle is also good, it can carry goods and pull people, and it is very suitable for some civilians to make money and support their families, and it is very versatile."

"The main thing is freedom, as long as it's not too far, you can go wherever you want."

"It's very suitable for personal use, which happens to be an important missing part of our current transportation structure, we have trains, airships and ships at a distance, and even animal carts, but at close range, there is really no suitable one, I just don't know if it's expensive or not, and whether civilians can afford it?"

After the branch minister finished speaking, he kept watching them discuss technology and usefulness, and now that he heard them talk about popularization, he said, "Don't worry about this, the technology submitted by this reserve is very comprehensive, and there are many patents for related manufacturing equipment, with the ability of our Black Rock City, there is no problem in mass production." ”

"The manufacturing technology of the bicycle is not very demanding, the materials are steel and rubber, there is no need for expensive materials, and if it is mass-produced, the price will not be very expensive."

"And it's light, small, ride-and-go, it's okay to carry people and cargo in general, and you don't need to worry about taking care of beasts, as long as you are careful not to treat it too roughly, it's no problem, I think it's still very attractive to ordinary people."

Hearing what the branch minister said, everyone present was relieved that steel and rubber were common.

In the west, there are not only coal mines, but also some iron mines, so there is no shortage of steel in the city, and there are large rubber forests around the mirror lake in the south, where there are now many villages that live on rubber.

The monthly journal of new inventions, whether it was headquarters or local, was something they had to keep an eye on, and from the recollection, they really didn't find any other place with similar inventions.

The only thing that is relevant is the wooden thing with pedals, and it is classified into miscellaneous things, patents are basically equal to none, invention points are also symbolically given one point, and each researcher can only apply for "miscellaneous" ten times in his life, so the impact can be ignored.

General inventions and creations are traceable, and it is impossible to appear suddenly, and it should be unlikely that something similar to Dong Chen's bicycle will be invented within a month.

But it is not excluded that like Dong Chen, he has been studying in private, and there has been a major breakthrough recently, which cannot be stopped.

Whether Dong Chen can get this project and whether he can put this project into the branch still depends on the final query results.

Looking at the people who were talking below, Tian Gengze knocked on the table and said, "In this way, the normal process must be followed, but in order to understand the relevant information as soon as possible, you can use the fastest airship to send letters to ask your friends in various places after you go back, and the cost will be paid by the branch." ”

"Although this will trouble you a little, as long as the level of the branch is raised and the points are ranked high, it will also be good for you, so try to have a snack."

"Understood, Chief." Everyone agreed.

"Then the meeting will be dismissed and we will get busy."

Tian Gengze announced the adjournment of the meeting, but stopped Andorf who was sitting next to him, "Andorf, that Dong Chen is your student and works in your school, isn't he?" ”

"It's a bit of an exaggeration to say that the student is a student, and I didn't teach him anything, I was only entrusted to take care of him, but I did work in the school library." Andorf replied briefly.

"Okay, tell him when you go back, I'll send someone to see the real thing he made in the afternoon, so that he doesn't run around."

"That's no problem, he usually stays in the school library, he knows my assistant very well, I'll let you know, and I just want to see how his stuff is."

Andolph shook his head and smiled, "I seemed to be a little self-righteous, as if I was a little wrong to blame this little guy, maybe I will have to apologize to him." ”

"Oh, and that kind of thing?" As soon as he heard this, Tian Gengze became interested, picked up Andorf and walked to his office.

"Let's go, I have the latest "Flower Tea After the Rain" there, go and taste it, the aroma is very good. ”

"You old fellow, you're still so gossipy......"
