Li Zexuan ran to the back kitchen and found a very thick piece of wood after searching for a long time. After careful identification, it turned out to be a yellow birch tree. Good luck!

Yellow birch is fine and strong, easy to polish, and has good nail holding power and is not easy to deform. It is a good material for making skateboards.

That's right, what Li Zexuan wanted to do for Laner was a skateboard, but it was a scooter with a handle on the front. This kind of skateboard has a higher safety factor.

Li Zexuan carried the wood with one hand and came to his small yard, where Laner was still waiting for him.

Laner saw that her brother had brought a big piece of wood over, and ran up to ask, "Is my brother going to make a puppet for Laner? But what's so fun about puppets?"

This little girl is still picky, Li Zexuan pinched Laner's porcelain doll-like face in a funny way, and said with a smile, "Of course it's not a puppet. What technical content does a puppet have?"

Laner patted her brother's hand away, wrinkled her little nose, and said displeased, "Brother, your hands are dirty."

When Li Zexuan saw it, he had just picked wood for a long time and forgot to wash his hands. Seeing that Laner was turned into a cute little cat, Li Zexuan laughed dryly, fearing that his little sister would retaliate, and hurriedly went down to the porch to go skateboarding.

......

Li Zexuan first used the wind chasing sword to cut a piece of wood that was about forty centimeters long, ten centimeters wide and five centimeters thick. The wind-chasing sword cuts iron like mud, and cutting wood is as easy as cutting tofu, and the end surface of the cut wood is as smooth as a mirror, and no additional grinding is required at all.

Li Zexuan sighed, this Wind Chasing Sword is an artifact for woodworking.

If Master Lingxu heard his current sigh, he would not know if he would climb out of the tomb in anger and clear the door.

Li Zexuan cut the shape of the skateboard, took the market ruler, measured the size, drew the force axis and the wheel connecting rod line, picked up the wind chasing sword, aligning the position of the wheel connecting rod, and used the infuriating energy, only to see the chase The wind sword began to spin rapidly in Li Zexuan's hand, and soon two through holes were drilled on the side end of the skateboard.

Li Zexuan looked at the Wind Chasing Sword in front of him, and the more he looked at it, the more he liked it. It can be used as a saw, as a chisel, and as an electric drill. It's really an artifact, hehe.

Laner, Xiaohe, and Xiaoxi watched Li Zexuan's series of magical operations, and they were all stunned.

Lan'er couldn't help but asked in a low voice, "Brother, was your master also a carpenter before?"

Li Zexuan's mouth twitched violently when he heard the words, and he mourned for the master who was underground. The first master of the world, the great master of martial arts, and a fairy-like figure was actually called a carpenter by the little girl Laner.

Li Zexuan said angrily: "What nonsense, this carpenter's kung fu is taught by your brother and I, don't arbitrarily arrange master and his old man."

Laner also realized that she had made a blunder, agreed, and continued watching her brother make toys for her.

Li Zexuan cut two short sticks that were slightly longer than the width of the skateboard. After polishing them very smoothly, they inserted them into the holes just drilled and used them as wheel axles. There were no ball bearings in this era, so they could only be used in this way.

Without rubber tires, Li Zexuan could only make two pairs of wooden wheels, which were nailed to the axles.

Finally, I got a T-shaped wooden pole and fixed it in front of the skateboard as a handlebar.

In this way, Datang's first super simplified scooter was born.

"Laner, come here, put your hands on it, step on the skateboard with one foot, and put the other foot on the ground. Come and try."

After packing up the tools, Li Zexuan demonstrated the movement and urged Laner to try it.

Laner was eager to try it, but she didn't know how to play with this thing. When she heard what her brother said, she immediately grabbed the scooter and started to slide forward slowly according to what her brother said.

Pure wooden scooters are indeed much jerky than those made with modern craftsmanship. Li Zexuan could hear the jerky "squeak" when the scooter was started.

Fortunately, his wheel holes and axles were polished relatively smoothly, Laner exerted a little force, and the skateboard began to slide.

"Ah..." Laner just kicked her foot, and the skateboard slid forward. She didn't have a good grasp of her center of gravity.

The two little maids watched their hearts in their throats, but Li Zexuan was not worried. The speed of the scooter was not fast. Once Laner adjusted her focus, it would be completely fine. Even if there is an accident, he is confident that he can save the little sister.

Sure enough, at the beginning, the girl was careful not to pedal too fast, just like a slender lady, pedaling small steps there. After getting used to it, the little girl became daring and started to go crazy.

"Wu~, brother, you see Lan'er will be able to do it lightly, come and chase!" Laner gently kicked, and saw the scene beside her rushing back, feeling the wind-like speed, Lan'er stomped gently. The child was extremely happy and couldn't help cheering.

Sure enough, no matter what era, this scooter has a fatal attraction to children.

Looking at the cheering little girl in front of him, Li Zexuan's thoughts flew back to his previous life. At that time, there were bear children riding skateboards racing against each other everywhere on the street. .

Perhaps, he can give this scooter to the children of Datang more than a thousand years in advance. As for the parents of the bear children, it is not up to him if they have a headache or not!

By that time, Chang'an City will be full of people stepping on it.

The bear child of the scooter is also very interesting to think about.

While playing, Laner felt that her brother's west yard was not big enough, so she stepped on a skateboard and went to the front yard.

Li Zexuan shook his head amusingly, and followed Xiaohe and Xiaoxi.

......

Li Jingmo went to a clothing store in West City this morning. A few days ago, after the introduction of several old business friends, he recruited a new shopkeeper for the clothing store. His name is Sun Huaiming. He is in his thirties. Honest.

Today, Li Jingmo went to see the operation of the ready-to-wear shop, and found that Sun Huaiming was very smart. He introduced a lot of novel ready-to-wear styles, which were very popular. Just a few days ago, the operation of the ready-to-wear shop was obviously much better than before.

Li Jingmo was in a very happy mood after reading it, and he came back after encouraging Sun Huaiming.

As soon as I entered the house, I saw my daughter stepping on a strange wooden board and rushing over here.

Laner was overjoyed when she saw Daddy at the door. She wanted to show Daddy her new toy immediately, so she shouted happily, "Daddy, Daddy, you think Laner will be easy to work on."

While talking, he kicked his skateboard vigorously and rushed towards Li Jingmo.

The speed of the skateboard is getting faster and faster, and it is getting closer and closer to Li Jingmo.

"what…!"

After a while, I heard Lan'er scream. The little girl just accelerated and kicked too fast. It was too late to slow down, and she couldn't help but panic.

Li Jingmo also discovered the danger at this moment. He could let the door open to avoid being hit, but behind him was the door of the house. If Laner hit it, he would have to break his head and bleed, and he would be reluctant to let his daughter get hurt.

Li Jingmo made a decision in an instant and stood there waiting for his daughter to bump into him, but with his old arms and legs, it is estimated that after such a bump, he won't be able to get out of bed for two months! I just don't know where Lan'er stepped on this thing from. When I look back, I must punish the servants in the lower house. How can I let Laner play with such a dangerous thing.

Laner saw that she was about to bump into her father, her face flushed with anxiety, tears rolled down her cheeks, and she regretted her complacence just now. She was so kind to her, she was reluctant to let her be hurt.

Seeing that she was about to meet her father, Lan'er suddenly felt a flash in front of her eyes, and then she was hugged and flew into the sky. She turned her head and saw that it was her brother who picked up her even with the car.

The little girl understood that she was rescued, and her father didn't need to be injured because she was injured. She immediately became very excited, hugged her brother tightly, and whispered, "Thank you, brother!"
