Yang Yan brought Luoluo a cushion to sit, but it was not just for her to sit. This cushion was similar to Sun Wukong's go out to beg for alms and used a golden cudgel to draw a circle on the ground. If Luoluo sat obediently on the cushion, it would be very safe, and there was no need to worry about the harm of demons (dad's tools)!

Of course, a monk like Tang Monk, who is so honest and honest, will not sit in the golden circle safely. Every time he is coaxed out by Zhu Bajie, let alone the lively and active Luo Luo!

After sitting on the futon for a few minutes, the little girl couldn't sit still. She raised her little butt slightly and tried it.

However, Yang Yan took a little attention to his daughter's movements. Luo Luo moved for a moment, and he immediately turned his head, with a gentle smile in his eyes, and looked at Luo Luo.

"Hehe, hehe!" Luoluo was like a child who was about to do something bad and was discovered by his father. Her hands were retracted and she hid behind her body. Then she narrowed her eyes and laughed embarrassedly to her father.

"Sit down! Don't touch these tools, it's very dangerous!" Yang Yan reminded him with a funny look, then turned back and continued to remove the screws on the wheel part of the "Chuanchuan".

Luo Luo was "catched" by her father and finally she could sit steadily for a longer time. She was still staring at her father, and finally waited until her father put down the "buzzing" thing.

"Well, dad!" Luo Luo's voice was crisp and she called her father. When her father turned to look at her, she happily raised her playful little eyebrows, smiled sweetly with her father, and asked, "Jie, is Jie Shen?"

"This is an electric screwdriver!" Yang Yan looked at Luo Luo's eyes. He did not act impatient, but picked up the electric screwdriver and introduced it to the girl softly, "Dad can use this thing to unscrew the screws. Because it is electric, it is still very convenient to use and is more labor-saving!"

After receiving his father's reply, Luo Luo's restless heart calmed down a little. She sat there, tilted her little head cutely, and continued to ask in a soft voice: "Dad, what are you doing?"

"Dad is working on 'Chuanchuan'. You have to open its shell first before you can do something else." Yang Yan said with a smile.

"Jane..." Luo Luo didn't know if she understood it, but she seemed to understand it, and nodded suddenly.

Yang Yan glanced at Luo Luo and put the electronic screwdriver he picked up in his hand back into his toolbox. Although it would be useful later, there was no secret switch for this thing. If it was placed casually on the ground, Yang Yan was still worried that Luo Luo would catch it and play.

Put it in the toolbox and take it later. It’s okay to spend some effort, safety first!

In the past, the body of "Chuanchuan" was modified by toy cars. This time, Yang Yan bought more professional tires and transmission systems from the Internet - these were specially customized for those DIY enthusiasts. Yang Yan searched for a long time before finding such a special toy car modification store.

After disassembling the previous wheels and suspension system, Yang Yan took out the newly purchased wheels and its complex suspension and transmission accessories from the opened express box.

The new wheel is very interesting. It has rough patterns on it, and the gap between the textures is also very large. When you touch your fingers, you will feel like you are pricking your hands!

Of course, what's even more fun is that each wheel has a separate bearing! Needless to mention the differential, Yang Yan also deliberately changed his core code to correspond to its differential control requirements, but Yang Yan now holds the wheel in his hand, and is playing with the function of its wheels being able to twist individually!

Luo Luo was surprised to see that his father was holding a pair of wheels in his hand, and he was able to twist one of the wheels around like pressing the switch!

Luo Luo didn't understand the mystery, but the asymmetrical movement of the two wheels could still make her feel some wonderful sense of incongruity!

"Well, Sue, is Sue so serious?" He asked when he didn't understand, and Luoluo's tender screams rang again.

Yang Yan turned his head and saw the little girl's curious eyes. He still explained patiently and seriously: "This is the wheel of the car! However, our wheel is amazing. It can run off-road tires with many extreme terrain, and then it is driven by axle, which is different from ordinary all-terrain cars. It has very powerful performance!"

"Scream, shout, are you so tired?" Luo Luo looked at her father in a daze and exclaimed.

She didn't know where the awesomeness was, but her father said it was amazing, and she also thought it was amazing!

I have to say that although Luo Luo sometimes affects the progress of her modification of this toy car, Yang Yan still felt very happy when he heard her sigh and looked at her admiring little eyes.

I feel that this is more motivated to show off my skills!

Yang Yan simply assembled the new wheels of "Chuanchuan" and explained to his daughter endlessly: "Luoluo, the car that my father made today is very particular. Not only did he use this all-terrain car technology, but he also specially found someone to design this electromagnetic power assist system. It can be said to be a black technology!"

It is indeed black technology. Electromagnetic power can improve the passing of cars to complex terrain. There is no such configuration in real automobile technology. However, in the toy car and model car industry, you can use any fantasy ideas at will. Anyway, it is a toy car, which is not a human being, and it is a random abuse!

Luoluo didn't understand what her father was talking about. She opened her mouth blankly and looked at her father intently, as if she was a good student who listened carefully!

It took a lot of time to modify it. After all, Yang Yan is not a veteran in car modification. He fiddled with the concept of his computer for more than two hours before installing the four wheels of "Chuanchuan" and the new four-wheel drive, suspension and other systems. By the way, he also replaced the new lithium battery pack for "Chuanchuan" so that its battery life can keep up with the new system requirements.

After the modification, Yang Yan first packed all his tools and placed the toolbox on the table to prevent it from falling when he was not paying attention.

"Okay! We can test the drive!" Yang Yan smiled, took out the new remote control, and gestured to Luoluo.

"Is that OK?" Luo Luo raised his little head after realizing it, and looked at his father with surprise.

"Yes! But Luoluo, you have to stand on the sofa. Dad wants to test the driving. I don't know if I can control it well, for fear of hitting your feet!" Yang Yan said to Luoluo with a smile.

"Well, Luoluo, Luoluo wants to play..." The little girl became anxious. She probably mistakenly thought that her father didn't want to participate by herself. She jumped around her father in a hurry, "Dad, Luoluo plays, plays, okay?"

"Dad isn't you not letting you play!" Yang Yan was a little amused, "Let's do it like this, Dad sits on the sofa with you, let's try the car together to see how it will be after it is modified. Is it OK?"

The modified "Chuanchuan" has no significant change in the theoretical speed and will not be too fast. Yang Yan is also worried that it will damage furniture and hurt children.

But it has not been tested and does not know how the control performance is. Yang Yan is also worried that he will command it to drive forward, but it will drive backward out of control.

No matter how slow the car is, it will hurt if it hits your toes unexpectedly!
