Otaku Engineer in Great Tang Dynasty

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

　　 Yellow birch is meticulous 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.

　　 Yes, what Li Zexuan wanted to do for Lan Er was a skateboard, but it was a scooter with a handle in front. This kind of skateboard has a higher safety factor.

　　 Li Zexuan came to his small yard with the wood in one hand, Lan'er is still waiting for him here.

　　 Lan'er saw that his brother had brought a big piece of wood over, and ran forward and asked, "Is my brother going to make puppets for Lan'er? But what's so fun about puppets?"

　　 This little girl is still picky. Li Zexuan squeezed the small face like a Laner porcelain doll with a smile, "Of course it's not a puppet. What technical content does a puppet have?"

　　 Lan'er patted her brother's hand away, wrinkled her little nose, and said displeasedly: "Brother, your hands are dirty."

　　 Li Zexuan saw that he had just picked wood for a long time and forgot to wash his hands. Seeing Lan'er being turned into a cute little cat, Li Zexuan laughed, fearing that the little girl would get revenge, and quickly went down to the gallery to do skateboarding.

　　...

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

　　 Li Zexuan sighed secretly, this chasing sword is an artifact for carpentry work.

　　 If real person Lingxu heard his current sigh, he would not know if he would crawl out of the grave and clean the door angrily.

Li Zexuan cut the shape of the skateboard, took the market ruler, measured the size, and drew the center axis of the force and the wheel connecting rod line, took the chasing sword, aligning the position of the wheel connecting rod, carried the infuriating spirit, and saw chasing The wind sword began to spin rapidly in Li Zexuan's hands, and after a while, two through holes were drilled on the side of the skateboard.

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

　　 Lan'er, Xiao He, and Xiao Xi were stunned when they watched Li Zexuan's series of amazing operations. They haven't seen a carpenter, but such a carpenter, who else is there in Datang?

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

　　 Li Zexuan's lips twitched fiercely when he heard the words, and in his heart mourned for the master who was underground. The number one master of the world, the master of martial arts, and a fairy-like character, was even described as a carpenter by the little girl Lan'er.

　　 Li Zexuan said in a huff: "What nonsense, this carpenter's kung fu is your brother and I taught myself, don't arrange the master and the old man casually."

　　 Lan'er also realized that she had made a mistake and agreed, and she continued to watch her brother make toys for her.

　　 Li Zexuan cut two short sticks that were slightly longer than the width of the skateboard. After they were polished extremely smooth, they were inserted into the newly drilled holes and used as wheel axles. There are no ball bearings in this era, so they can only be used first.

　　Without rubber tires, Li Zexuan could only make two pairs of wooden wheels and nail them to the wheel axles, thinking that in the future, he would find a blacksmith to make an iron cast. The wood is not wear-resistant.

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

　　 Thus, Datang’s first super simplified version of the scooter was born.

　　 "Lan'er, come here, hold your hand on it, step on the skateboard with one foot and the other foot back on the ground. Come and try."

　　 After packing up the tools, Li Zexuan demonstrated the action, urging Lan'er to try.

　　 Lan'er had been eager to try it, but she didn't know how to play with this thing. When she heard her brother's words, she could not wait to **** the scooter over and started to slide forward slowly as her brother said.

　　Pure wooden scooters are indeed much jerky than modern craftsmanship. Li Zexuan can hear the jerky "squeak" when the skateboard starts.

　　 But fortunately, his wheel holes and wheel axles were polished smoothly. Lan'er tried a little bit and the skateboard started to slide.

　　 "Ah..." Lan'er just kicked her foot and the skateboard slid forward. She didn't grasp the center of gravity, and her small body couldn't help but leaned back and she couldn't help but exclaim again and again.

　　 The two little maids mentioned their throats as they watched from the side. Li Zexuan was not worried because the scooter was not fast. Once Lan'er adjusted the center of gravity, she would be completely fine. Even if there is an accident, he is sure to save the little girl.

　　 Sure enough, at the beginning, the girl was cautiously not daring to kick too fast, like a slender lady, kicking small steps there. After adapting, the little girl became courageous and started to go crazy.

"Woo~, brother, you think Lan'er will be easy, come and chase it!" Lan'er gave a light kick, and saw the scenery next to him scurrying backwards, feeling the speed of the wind, Lan'er The child's heart was extremely cheerful and could not help cheering.

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

Seeing the cheering little girl in front of him, Li Zexuan's thoughts have flown to his previous life. At that time, there were children and bears racing each other on skateboards everywhere on the street. They could always play for a whole day without getting tired of playing. .

　　Perhaps, he can give this scooter more than a thousand years in advance to the children of Datang. As for the parents of bear children, if they don't have a headache, they won't be in his charge!

　　 Until then, there are a group of bear kids on scooters everywhere in Chang'an City, which is quite interesting to think about.

　　 Lan'er felt that her brother’s west yard was not big enough, so she went to the front yard on a skateboard.

　　 Li Zexuan shook his head amusedly, and followed with Xiao He and Xi.

　　......

Li Jingmo went to the clothing store in West City this morning. A few days ago, after a few old business friends introduced him, he recruited a new shopkeeper for the clothing store. His name was Sun Huaiming, who was in his thirties. He was shrewd and capable. Honest.

　　 Today, Li Jingmo went to look at the operating status of the garment shop and found that Sun Huaiming was extremely smart. He introduced a lot of novel garment styles and was very popular. Within a few days of his arrival, the operating situation of the garment shop was obviously better than before.

　　 Li Jingmo was very happy after reading it~www.ltnovel.com~ After encouraging Sun Huaiming to live, he returned.

　　 As soon as she entered the house, she saw her 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 her new toys to Daddy immediately, so she happily cried out, "Daddy, Daddy, you think Laner will be lighthearted." She said, pedaling hard. Charged towards Li Jingmo.

　　The skateboarding speed is getting faster and faster, getting closer and closer to Li Jingmo.

　　 "Ah...!" After a while, I heard Lan'er scream. The little girl just accelerated and pedaled too fast. At this time, it was too late to slow down, and she couldn't help but feel a little frightened.

　　 Li Jingmo also discovered the danger at this moment. He was able to avoid being hit, but behind him was the gate of the mansion. If Lan'er hit the door, he would have to be bloodied and he would not bear the injury to his daughter.

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

　　 Lan'er saw that she was about to bump into her father, her small face flushed anxiously, tears rolled down, and she regretted the ecstasy she had just done. She was so kind to her that she couldn't bear to hurt her father.

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

　　 The little girl knew that she had been rescued, and her father didn’t need to be injured because she was injured. She was so excited that she hugged her brother tightly and whispered, "Thank you, brother!"
