Movable type printing is very simple, but it is actually a flexible use of molds.

Tieda, the three brothers of the Tie family, came with a tricycle that had been built.

Except for the difficult chain and transmission device, other parts are not difficult to make.

Tie Da smiled honestly and said, "I don't know if it's the same as the county marquis thinks."

Li Zheng looked up and down the tricycle, then rode on the pedal and started moving.

After riding for a while, I found that it was quite stable. Most of them were made of wood and I felt that the load bearing would not be very good.

However, this is also a technical breakthrough.

Li Zheng rode his bicycle into the village.

Tie Da followed along the way, and even he himself didn't realize that the things he made were so magical.

As I rode all the way into the village, I saw Li Zheng passing by on the three wheels and the villagers almost frightened.

Two or three aunts in the village who were drying clothes were dumbfounded when they saw this scene.

I didn't know what to say for a moment.

Li Zheng rode all the way to the entrance of the academy, and a large group of children followed him and watched the monster that could move by himself.

When Cheng Chumo saw the thing Li Zheng was riding, he jumped up in shock, "Yeah! What kind of monster is this!"

Li Zheng wanted to stop the tricycle, but then he realized that he had forgotten to design the brakes on the tricycle, and he hit a tree before stopping.

Cheng Chumo leaned forward and asked, "Li Zheng, what kind of monster is this?"

"I haven't seen it before." Li Zheng said from the tricycle, "This is not a monster, this is a tricycle."

"A tricycle? Isn't it just three wheels?" Cheng Chumo said with a look of surprise.

"Yes." Li Zheng nodded, "Look at it, it's just three wheels, what a vivid name. I call this Jingyang tricycle."

Cheng Chumo looked around the tricycle and circled, "How is this thing made? It can be moved by itself without pulling animals."

As a master craftsman in the court today, Yan Liben naturally cannot let go of such things when he sees them.

He didn't even attend classes and followed him in a hurry. Yan Liben and Cheng Chumo observed this tricycle that could be moved by himself.

Yan Liben said, "Li Zheng, how did this be done."

"In fact, it is a principle of transmission." Li Zheng explained to Cheng Chumo: "If I step on the pedal, the gear will rotate as the pedal moves. The gear will drive the chain, and the chain will drive the gears behind it, and at the same time drive the wheels to rotate."

"So it can move on its own?" Yan Liben asked.

“It’s that simple.”

Yan Liben grabbed the back of his head and saw that the structure of the tricycle was indeed very simple.

It's so simple that it's a bit unreasonable, but no one has created such a simple thing.

Yan Liben sighed: "I know that the craftsmen of the Mo family Gongshu were so skillful that many craftsmen in this world have been lost."

While speaking, Yan Liben's expression also began to be excited, as if he was a yearning for the Mohist school and Gongshu.

In ancient times, when industry was underdeveloped, many craftsmen would regard Gongshu and the Mohist school as their ancestors.

They are the ancestors of the craftsmanship industry, which has led to so many craftsmen who have been passed down from generation to generation.

Yan Liben asked: "Li Zheng, since it is so simple, why don't you make this thing earlier?"

“No need before.”

"need?"

Li Zheng said: "Yes, it's the demand. In the past, there weren't so many goods in the village. Now there are more and more businesses in the village, and there are only two cows in the village. Now, with this tricycle, it's easier."

After hearing what Li Zheng said, Yan Liben sighed to the sky: "It's actually for convenience."

Li Zheng said again: "Is it possible that I still have some fun for a walk?"

Yan Li asked anxiously: "I don't know when the county marquis will find it inconvenient."

Li Zheng looked at Yan Liben strangely, "Why did Master Yan say this?"

"If the county marquis can create more ingenious things, I hope the county marquis can tell you."

It can be seen that Yan Liben's desire for craftsmanship skills is in his heart.

Li Zheng sighed: "Actually, these are all knowledge. I have recorded in the academy's books. This is the principle of power transmission. When we shake trees, we can shake the trunks. When the trunks shake, the branches will also shake, and then the fruits on the trees will fall. I believe that there is no need for me to say more, Yan Dajiang must also understand this principle."

"This old man naturally understands, just..."

Yan Liben sighed again after saying that, bowed and said, "The officials have not considered so much. Over the years, I have seen many craftsmen. They are all proud of their skills, but they have never thought about creating something."

"I have known since I was a child that I always want to benefit the world, but it has become a world of fame and fortune for craftsmen to compete in craftsmanship. It is not a kind of sorrow. It is really sad to only compete in finesse but not know how to create things."

Li Zheng comforted Yan Liben and said, "This is a matter of knowledge expansion. It is true that pursuing superb craftsmanship is indeed worthy of being proud of."

Whether from the pre-Qin period to the Tang Dynasty today, craftsmen are the ancestors of all craftsmen in later generations.

The horizontal knife craftsmanship of the Tang Dynasty was already very exquisite. Until more than a thousand years later, the manufacturing and forging technology of the horizontal knife would still be talked about by later generations.

These are the crystallizations of wisdom left by our ancestors and the Tang Dynasty.

Although I know more advanced forging techniques, I cannot forget where my knowledge comes from.

Cheng Chumo said excitedly: "Li Zheng, can I give it a try?"

"Of course, Brother Chumo tried it, I would still try the quality of this tricycle, and there are still many things that need improvement."

Cheng Chumo smiled and got on the tricycle.

"Just try, Brother Chumo must not be polite."

"Okay!" Cheng Chumo took a deep breath and stepped on the pedal hard.

With Cheng Chumo's brute force, the tricycle traveled very fast. This guy completely treated the tricycle as a horse and blindly pursued speed, which was Cheng Chumo's three views. For him, there was no fine food, and what could be full was good food.

The wine that is strong is good, so that Cheng Chumo is still worried about the first bowl of wine he gave him. It seems that the alcohol content of the Cheng Family Wine House is not very satisfied.

Yan Liben almost burst into tears when he saw that he could drive the tricycle quickly without a horse.

A tricycle does not need to be pulled by animals or by people. Just step on the pedal and you can move it.
