A month ago.

Xu Mu said he wanted to give her a gift.

It made her happy for a long time.

But she waited around the institute and waited for nearly a month before waiting for Xu Mu.

She thought Xu Mu would never come back.

At this time, she was very happy to see Xu Mu and ran towards Xu Mu.

Xu Mu touched her little head and then gave her a book.

"There is magical knowledge in this book. You can study it carefully. I will see how you learned it later." Xu Mu briefly explained.

In order to make Lin Qingcheng more interested, Xu Mu also asked Yan Liben to help him draw corresponding illustrations for this book "Natural Science".

For example, when he denied the theory of the world and the world, he specifically asked Yan Liben to draw a ball.

All kinds of weather and natural lightning were painted in it by Yan Liben.

Lin Qingcheng took the book, and she was simple-minded and didn't think much about it, so she started reading it directly.

Under Xu Mu's previous arrangement, the craftsman who read literacy in the institute had taught her to read.

Seeing Lin Qingcheng studying hard, Xu Mu... turned around and planned to leave the institute.

Suddenly I was called out by a craftsman.

"Lord! Another thing has been developed successfully!"

As the end of the year approaches, the institute has made another breakthrough.

Xu Mu followed him and saw a car...

bike!

That's right, it's a bicycle!

He proposed this two-wheeled bicycle that can be trampled a long time ago.

And let the craftsmen of the institute be included in the project plan.

But later, I was busy dealing with the matters in Henan and Chang'an, and I forgot it.

“Can you ride it?”

Xu Mu looked at the bicycle with a very "technological" feeling in front of him and his eyebrows moved.

The craftsman nodded: "We have experimented and can ride it!"

He paused and continued: "The above joint conveyor device is currently using a wooden structure, which may be insufficient durability, but it should be able to complete the corresponding optimization within the next year!"

The chain polishing technology is still too forced for the institute.

Moreover, there is no rubber, and the bicycle does not have tires for shock absorption and wear resistance, so its service life is generally not very long.

Xu Mu nodded.

It will be resolved within one year and replaced outside, which is only one month.

"Hurry up and develop alternatives."

Xu Mu reminded him, and then...

I took this finished product away from the institute.

He plans to show Lao Yang and the buns of local buns in the lord’s mansion what technology means to change life!

...

In front of the lord's mansion.

Xu Mu summoned Lao Yang, Er Pei, He Chou, Cui Ji, Yan Liben and others.

Everyone was looking at the "car" with two wooden wheels in front of them.

"Lord, what is this?"

Pei Yun, director of the Craftsman Department, couldn't help asking.

Xu Mu laughed, then turned over and started riding.

For him, riding a two-wheeled bicycle is not difficult.

But in front of these directors...

But it's incredible!

"Can you run in two rounds?"

"Will this not turn over?"

"Why can the key lord... run so fast?"

...

Everyone, including Yang Guang, was confused.

They have seen cars.

But I have never seen such a simple car.

In their impression, most cars are three-wheeled or two-wheeled.

It’s definitely not like Xu Mu… two rounds, one in front and one behind.

If you look like this, won’t you lose balance and turn aside?

But after seeing Xu Mu keep speeding up...

The speed is getting faster and faster, and the eyes are brighter.

They gradually discovered the awesomeness of this car.

There is no need for any cattle and horse to drag...

Can you run by yourself?

And the speed is amazing?

It is already comparable to a person's normal running speed!

After Xu Mu's "performance" ended, everyone surrounded him.

Yang Guang stood closest to the bicycle, stroked the strange car in front of him, and couldn't help asking: "Lord, what's the name of this car?"

They are all human spirits.

Xu Mu only showed it once, and they understood the great value of this thing!

As long as you lay cement, ride it and walk freely!

After Xu Mu got off the car, he explained to everyone: "This car is called a bicycle. It does not require cattle, horse and animal power and can move freely, so it is named bicycle."

When Pei Yun heard this, he was the first to suck his hands and said, "It is true that you can walk freely without external force. The name of a bicycle is worthy of its name!"

Others suddenly realized.

Then they asked if they could ride it.

Xu Mu glanced at the old men in front of him.

The oldest Pei Ju is already seventy...

If he falls a little longer, he will lose a large number of talents.

However, considering that the speed of the bicycle was not very fast, Xu Mu still agreed to them to test the bicycle.

"But you must be careful. This car has no brakes. If you want to stop, you can only slow down and then brake directly with your feet!"

This is a problem that Xu Mu discovered while riding a bicycle just now.

Because of the hasty, this first-generation bicycle has not been fully equipped in all major functions.

The brakes are not installed properly.

also……

To be honest, people with poor balance ability really can't control this car.

For example, Pei Yun, the first attempt.

As the director of the Craftsman Department, he was most curious about such ingenious artifacts.

but……

After he got on the car, he rode for only one or two meters, and he couldn't control his balance and wanted to overturn the car.

Fortunately, the young and strong Yan Liben supported him.

Afterwards, Pei Ju, Cui Ji, He Chou and others also tried one after another.

There was light in his eyes.
