Wei Shuyu returned to the room, took out the robot sledgehammer from his arms, and kissed him fiercely. He found that since he found the sledgehammer, his heart had become settled and calm, as if he had something to rely on.

With a sledgehammer, the impossible will become possible.

But at this time, Wei Shuyu had a trace of sorrow on his face, he knew that if he didn't solve the energy problem of the sledgehammer for a day, his heart couldn't really fall, if the backup power supply of the sledgehammer was used up, then the sledgehammer could only be used as an ornament and placed in the room.

After Wei Shuyu locked the door, he started the sledgehammer again. After switching to voice control, Wei Shuyu called up the information of various batteries, and then studied them in detail. Keep the materials you use in mind in case you need them.

Unconsciously, there was a "crunch", and Wei Shuyu knew that it was Wei Zheng who went to the early dynasty. Time flies, but Wei Shuyu still has a lot of things to do. He asked Sledgehammer to call up the information about the generator again, and when he saw that it was similar to the information in his memory, he turned off Sledgehammer and fell asleep.

Since coming to Datang, this sleep was the deepest sleep Wei Shuyu had, and it wasn't until the fifth sister knocked on the door that he woke him up from his sleep.

After getting dressed and walking out of the door, Wei Shuyu found that the sun was already hanging overhead, and seeing the expectant eyes of the fifth sister, Wei Shuyu remembered the toy he promised to the fifth sister last night.

"Big brother, what about the toys you promised me?" The fifth sister saw that Wei Shuyu was empty-handed, and said a little eagerly.

"Well, I tossed all night last night, and my eldest brother just got up."

"Big brother, you're a liar, woo woo woo ......"

"Good sister, don't cry, big brother will do it right away!" Wei Shuyu touched the fifth sister's head, and hurriedly pulled her to the kitchen together.

I took two steamed buns in the pot and nibbled on them while looking for wood in the firewood. Wei Shuyu plans to make a scooter for the fifth sister, a walk-behind scooter.

Under the supervision of the fifth sister, Wei Shuyu was busy and sweating, and after an hour, Wei Shuyu finally finished the frame, leaving only the pulley unfinished.

At this time, Wei Shuyu fell into deep thought, should he use wood to make wheels or fine iron to make wheels? If it is made of wood, the fifth sister will not play for long, and she will definitely have to play badly, and she will still come to pester herself when the time comes. If it is made of fine iron, then it is quite difficult for him to make the bearing by hand, and it also consumes time, especially the production of the inner and outer sides of the raceway and the ball.

In this way, it can only be completed by using an industrial robot sledgehammer, but the backup power supply of the sledgehammer is used less than once, and Wei Shuyu does not know how long the backup power supply can last.

Looking up and seeing the expectant eyes of the fifth sister, Wei Shuyu turned his heart sideways and used it. I'll talk about the power supply later, who made him have only such a sister.

"Little sister, you guard the door for me, don't let anyone come in and disturb me. The next step is very crucial, and if you are disturbed, your toy will break and you will never be able to make it again. Wei Shuyu pulled the fifth sister over, and then said with a serious face.

"Don't worry, big brother. I'm going to keep the bad guys in...... Even when my father came, I stopped him so that he would not come in and disturb you. ”

In the young heart of the fifth sister, whoever let him play without toys is a bad person, and obviously his father Wei Zheng is the worst one.

Wei Shuyu entered the room, and only after locking them did he summon a sledgehammer and voice control the sledgehammer to make bearings.

The sledgehammer spun its head in a circle, scanned the frame made by Wei Shuyu, and then began its work.

I saw that the sledgehammer slowly grew to a meter high, and then picked up a piece of fine iron in his left hand, and a stream of blue flames erupted from the index finger of his right hand, and after a while, the fine iron in his left hand began to change shape.

Then the sledgehammer stopped the flames, the ten fingers of both hands changed, and the three bearings and some fixing devices were completed under Wei Shuyu's nose.

Wei Shuyu was stunned, and the sledgehammer was like magic, and he got the bearing out, which was simply ......

Wei Shuyu came back to his senses and hurriedly checked the power supply, there were still ninety percent left. After a while, five percent of the power was used, which made Wei Shuyu feel a little distressed.

In the next assembly, Wei Shuyu didn't dare to let the sledgehammer go on anymore, otherwise the power would be reduced again.

Wei Shuyu decided that when it came to manual craftsmanship in the future, it was really not up to standard, so he let the sledgehammer go out. And what can generally be done by yourself, you must do it yourself, until you know that the sledgehammer power supply problem is solved.

"Ding Dong ......" After Wei Shuyu thought that compared to the operation of the sledgehammer, Wei Shuyu finally got the first scooter out of Datang.

Wei Shuyu carried the scooter and opened the door. Outside the door, the fifth sister was like a little guard, patrolling around over and over again, with a nervous expression on her face.

"Ahem......" Wei Shuyu found that the little girl didn't even notice that she was behind her, so she couldn't help coughing a few times.

"Bad guys, don't go in...... Big brother, it's you, scare me. Is my toy ready? ”

"Alright." Wei Shuyu lifted the scooter out from behind.

The fifth sister took the scooter with both hands, "Big brother, what is this?" ”

"Slippery pulley." Wei Shuyu said. He changed the name of the scooter to a more sensual sound.

"Slippery?" The fifth sister touched the wheel with her hand and found that as soon as she used force, the wheel turned.

"Well, fifth sister. The sliding block is not played with in the hand, but ...... Come on, come on, big brother will show you how to demonstrate. ”

Wei Shuyu saw the fifth sister holding the scooter in her arms, playing with the wheels vigorously, and cold sweat flowed from her forehead.

It seems that there is also a generation gap between the times.

"Okay." The fifth sister reluctantly handed the scooter to Wei Shuyu, "Big brother, don't break it." ”

"Well, it can't be broken. Look at it......"

Wei Shuyu took the scooter, stepped on the body with his right foot, held the direction pole with both hands, and quickly lifted it up after pushing the ground with his left foot. Wait until the speed of the scooter has slowed down, then kick the ground again.

Wei Shuyu controlled the direction and spun around the courtyard.

"Big brother, I want to play, I want to play, give it to me, give it to me, it's my pulley......" The fifth sister saw Wei Shuyu controlling the scooter, shuttling back and forth in the yard like the wind, and she chased after her. When he couldn't catch up with Wei Shuyu, he used a killer move, squatted on the ground, and shouted with a crying voice.

Wei Shuyu controlled the scooter to the fifth sister and handed the scooter to the fifth sister.

The fifth sister pedaled the scooter, and according to Wei Shuyu's method, she slid the scooter out with her feet on the ground.

Before Wei Shuyu could remind the fifth sister to pay attention to safety, the fifth sister hit the wall, and Wei Shuyu hurriedly ran over to pull the fifth sister up.

"Fifth sister, where is the injury?"

"Big brother, I'm fine, you let go of me, I'm going to play ......"

"Uh." After Wei Shuyu found out that the crybaby actually hit his head on the wall, he was fine, and he couldn't help but feel that the charm of the scooter was really great.

It seems that it doesn't matter whether the children of later generations or the children of the Tang Dynasty. There is a striking consistency in the treatment of toys.

Children learn things really fast, and in Wei Shuyu's concept, the fifth sister can already flexibly control the scooter to turn around in the yard.

"Okay, fifth sister, five sisters will go to see their mother together."

"Okay, big brother, you come with me......"

......
