"What is this guy riding?!"

"Who have you seen that thing?"

"The magic weapon? It's not a big deal. Besides, even a Taoist student cannot use magic weapon."

"It can't be a magic weapon, I think it's like... a two-wheeler."

Hu Yunhong stepped on the pedals of the "two-wheeled bike" with all his strength, and the speed was fast. When he was about to approach the martial arts field, he beautifully hit the dragon head, with one foot as the center of the circle, and stopped "swish".

This student Hu was also a little overly excited and forgot to take Xiao Tiejin in the back seat, whom he met halfway through. Fortunately, the latter was good at it, so he jumped out of the car in the air in a critical moment.

Because he was heading towards the east where the sun rose, he squinted his eyes and touched for a long time before he saw Li Zisheng in the crowd.

The always honest child waved to the young man excitedly and shouted: "Lei Gong, look! I've made your bicycle!"

Li Zi rose from the crowd and walked forward. He also happily patted the other party's shoulder and praised: "No, not bad. Lao Hu, I really didn't expect you to make this bicycle so quickly!"

Hu Yunhong said shyly: "If my father hadn't taken action, I wouldn't have done it alone in such a short time."

The Hu father and son are worthy of the four-word comments about skilled craftsmen. With the sketches drawn by Li Zisheng, he built the bicycle.

As an expert, don’t underestimate this bicycle, it is a veritable "high-tech" product.

By the way, I was in the Great Heavenly Kingdom and could not produce all domestically produced bicycles until 49 years later. Before that, most of the parts needed to be imported and then assembled in China.

That's because a bicycle has ball bearings, gears, chains, rubber tires, etc. These are parts that require a complete industrial system to make.

Fortunately, this is a world of fairy tales, and many of our plane technical problems are not a problem for weapon refiners like Hu Kaishan.

Hu Yizhi just lacks one idea.

In fact, a bicycle that seems to be constructed at a glance is a complex machine composed of many simple machines.

Machinery does not specifically refer to machinery and equipment. Items such as chopsticks, brooms and tweezers can also be called machinery. Of course, they are just simple machinery. Complex machinery is composed of two or more simple machinery.

Usually we call these more complex machines machines.

From machinery to machines, it is like from ape to humans. Although this step is small, it is of great significance.

The great significance of a machine is to transform the energy applied to it into its most useful form.

A wheel is a kind of machine. If the wheel is to rotate forward, it must also provide a forward force. However, when a person or a livestock directly provides tension or thrust to the wheel, it is necessary to overcome the potential energy decline and ground resistance caused by the change in the center of gravity. This is what everyone has learned in high school.

A complex machinery like a bicycle is actually composed of a number of simple machinery such as wheels. The power source composed of pedals, cranks and sprockets, a transmission part composed of a chain, a central shaft and a flywheel, and a front and rear wheels, as well as a moving device such as the front and rear wheels. Of course, there are steering control, brake devices, seat rear frames, etc.

These wheels, gears and levers combine to convert almost all the "total work" done into useful "mechanical work", which greatly reduces the "extra work" used to overcome potential energy waste and ground resistance.

Everyone present, including Li Zisheng, did not realize that at this moment, when the bicycle appeared in the world of Dajiu Continent, it meant that someone finally took the initiative to superimpose the machinery on other machinery and manufactured the machinery.

As a result, humans have another way to use the great power between heaven and earth... that is to say, the "yuanqi + Yuanshen + Yuanshi Technology" in Zhongzhou today, a strange branch has grown on such a scientific tree.

Of course, for the moment, these young children in their early teens only regard this bicycle as a very interesting toy, including the teenager himself.

"Old Hu, you can do it!" The young man looked at the bicycle and couldn't help but exclaim.

This "Zero Car" is indeed extremely gorgeous and has a beautiful feeling of "Chinese style" and mechanical combination.

The metal materials used on the car are all black steel unique to Tieshancheng. This black steel is doped with a little black iron used to prevent rust. Therefore, the color is dark and black, and it was originally used to create a good mortal weapon. Using such metal also makes the car look elegant and generous, with a kind of "low-key luxury".

The dragon head is carved from a whole piece of fine iron wood. This image is still a dragon that swallows clouds and mists. It is truly a true "dragon head".

In the middle of the handlebar is a "real dragon head" that sucks and spits clouds; the forks on both sides connecting the front wheels are four dragon claws holding beads, and the rest are dragon bodies carved with scales and decorated with cloud patterns. This piece is exquisitely carved, and it is obvious that it is from the hands of a master, adding a little bit of atmosphere to the car.

This car is more of a work of art than an industrial product.

After Li Zisheng carefully read it, he was also very impressed. He felt that the car was so gorgeous that it was a little exaggerated and he couldn't help but ask, "Old Hu, how much does this car cost?"

"Money? What money? Hi, this car is yours." Hu Yunhong touched his head and smiled silly: "My father was deeply impressed by your design drawings. He said that your drawing was priceless! If it weren't for his actions, I wouldn't know how to start some parts."

"Oh, I didn't expect that I would even alarm Ling Zun."

Hu Yunhong said embarrassedly: "It's okay. My father also said that he would invite you to come and talk to me if he had the opportunity."

Li Zisheng agreed: "Okay, okay. If you have the chance, please come to your door and ask for help."

Hu Yunhong stepped out of the car with his legs, pushed the car in front of the boy, and said as if offering treasures: "Senior Brother Li, come and try it."

"Okay." The boy agreed happily and took the car.

He held the handlebar and pushed it quickly for a few steps, then flew over and sat on the saddle in the middle and began to pedal.

A practitioner like Li Zisheng who has been practicing physical skills since childhood has no problem with the balance ability. He doesn’t have to deliberately grasp his center of gravity and ride it smoothly.

Under the envious eyes of the Taoists, he rode around the martial arts field.

When the boy returned to his original place, somehow the first thing he noticed was Liu Wuxia. She was looking at the bicycle curiously with her almond eyes open.

Li Zisheng jumped out of the car casually, pushed the car and walked to her, and said sincerely: "Junior Sister Liu, do you want to try it?"

"Hmph, I don't want it!" Liu Wuxia's face turned red, she turned her head and left.

Before the boy could start chasing him, a circle of Taosheng had already surrounded him.

Xiao Jiaqi complained, "Okay, Lei Gong. You and Lao Hu are exploring such fun things, and don't tell me, are you not treating me as a friend?"

Li Zisheng now knew that this classmate was straightforward, so he said without any mind: "How can it be? I didn't expect Lao Hu to make this bicycle so quickly. Come on, let's try it for you first."

"Well, this is almost the same." Master Xiao happily took the handlebars and rode them like these two people.

Someone asked Hu Yunhong: "Student Hu, is this bicycle made from your workshop?"

Hu Yunhong said proudly: "That's right, it was made by our Hu family iron shop."

Someone next to him said, "What... Is this bicycle sold? How much does it cost?"

Youdaosheng echoed: "Classmate Hu, I want one too!"

The Taoist students in the Tian and Di class are either rich or noble. If you see this fresh and interesting toy, you should buy one for yourself immediately, which is a shame for your background.

Just as the sky was about to burst into pieces, a bell rang to declare the beginning of this morning class.

The Taoists, even the great master Xiao who was riding happily, could only return to the martial arts field obediently and began to practice under the supervision of the Taoists.

However, when the morning class ended, Hu Yunhong, who had always been unattractive, suddenly became the focus of everyone, and he couldn't even eat lunch.

Wherever he went, there were a circle of small buyers who booked bicycles, making the child three big heads.

Hu Yunhong took the opportunity to take advantage of the situation and quietly pulled Li Zisheng to the corner and asked, "Senior Brother Li, can my family sell your bicycle?"

The boy blurted out naturally: "Why can't it? Of course!"

Hu Yunhong hesitated and said, "But... this car was designed by you. Then..."

"Oh, you say this. Just give me some patent fee." Li Zisheng replied naturally.

“Patent fee?!”

The boy was not so mean and explained: "It's just to give me the profits of each car... Well, it's better to have 30% of it."

"Ah?! 30%?" Hu Yunhong said in surprise.

"Thirty percent is too high?"

The honest child said honestly, "No, it's too low. Not all your creativity, at least half!"

The boy said generously: "Hey, don't worry about this between us. Besides, I want you to build a few more cars that are not that fancy, well, that... popular version for me to those distribution specialists."

Hu Yunhong nodded and said, "Okay, no problem."

He turned around and was about to recruit business, but the boy grabbed him.

Li Zisheng asked, "Lao Hu, how much do you price?"

Hu Yunhong blinked, touched the back of his head and said, "I think it's almost done with one Yuanshi."

"Ah?!" The boy was surprised. The price was really beyond his expectations. "How much does this car cost?"

Hu Yunhong thought for a while and said, "I really haven't calculated this, but I didn't use much material before and after. And it's all iron, and it's broken and turned back into the furnace."

"It's a bit more manual use! Your car was made by my father, and the faucet was carved by a friend of his own. But that was a trial production. After thinking about it, it was assembled for the workers below."

"So, this Yuanshi must have made a profit, and there are still a lot of them."
