When Kaichi assembled the bike, it was almost evening, and he tried it, and he could ride it, so he hid it.

It was getting late, and he was about to cook, and he didn't have to show it for long, so he had to wait for the next day to find an auspicious time, when the sun was the brightest, and then take it out to blind them.

Today's weather is just right, the sun is shining on people, there is no wind, and it is suitable to go out and bask in the sun.

After eating, Jia Yi took out his bicycle, the frame of the whole car was particularly wide, and the patterns on it revealed a mysterious atmosphere, of course, for ordinary people, for mages, it would soon be discovered that these patterns were variants of the magic array. The wheels of the car looked very shiny, as Kaichi cast a light at the silhouette with magic.

Seeing Flower go out, Jia Yi hurriedly got into the car, rode up, and deliberately passed in front of him.

"Jiayi, is this the car you built?" Flor was really attracted, and the young man still saw less routines.

Jia Yi said: "Of course, how about it, haven't you ever seen it." You also say that the two wheels can't move, but I don't need a horse, I can move it myself. ”

With that, he began to circle in front of the door, round and round.

He showed Flower the wooden model car without a chain and couldn't ride it, just pedaling underground. Now with your feet off the ground and riding in circles, it's completely different.

"Jiayi, give me a try. Before Flower could say anything, Dale rushed out of the house, grabbed the front of the car, and said.

Such a car is something they have never seen before, and the whole thing is made of steel, and if it is used to make weapons, it can almost equip a small team of soldiers.

However, it would be nice to be able to add power to it and become a magic power car, it would be too tiring to ride it by yourself.

Jiayi landed on his right foot, propped up the car, and said, "You won't!"

"It's okay, you can do it, I can't. ”

Dale is very dissatisfied with Jiayi for underestimating herself, riding a bicycle does not seem to be a big deal, but almost no one can do it the first time. But I don't know why some people can ride electric cars and motorcycles directly, but they can't ride bicycles.

Although Jia Yi feels that he hasn't played enough, how many years have passed, and finally got on the bike again, he hasn't saved enough feelings. If it was Flower, he wouldn't let it, but who called Daile a cute girl.

Although many people say that they can't walk when they see a woman or something, but there is really a cute cute girl who begs you softly, you really can't refuse, especially when this request is not too much. However, Daile's tone was not soft.

The rest of the day was a flurry of chickens and dogs, and both Dale and Flower rushed to learn how to ride a bike, but they were both seeing this thing for the first time, and they both stumbled on the ride.

Flower is better, he's tall, and when he has a problem, he stabilizes himself with his feet on the ground, and he's a little more durable. But Dai'er is small, and someone must support her behind, otherwise she will fall down if she can't ride 3 or 5 meters away.

Jiayi's bicycle has no brakes, and the brakes are more troublesome to build, and for old drivers, there is no difference whether there is or not. The main reason is that he wants to build the car first, and he has time to install it after the brakes, but after the car is built, he doesn't want to brake anymore.

Because the bicycle was snatched away, Jia Yihao went to make eucommia glue and wanted to make a tire out. Tires are not only bicycles, but can also be used in horse-drawn carriages. However, as a magician, it always seems a bit unethical to do these things without magic, but who called Jiayi's strength is insufficient.

But these inventions are not useless, these have laid a solid foundation for making magic items in the future, and now Jia Yi has also begun to think about how to change these inventions, but whether he can do it or not.

He went to find the eucommia forest that Yimu said, and originally thought that eucommia was the same as a rubber tree, and it was enough to cut a wound, but he didn't expect that he cut the wound and came out, and waited for a whole day, but he didn't get any glue. Looking at the wounds of the eucommia tree, it is true that there is glue between the broken bark, but it is like a semi-solidified glue, and it does not flow at all.

Only then did he understand why Im had told him that it was the eucommia gum that was extracted from the solvent instead of being cut.

Then, he went to find the paper that Imu had said, which had a simple way to extract Eucommia gum by extracting Extract No. 7. Although Imu has read this paper, he does not have the memory of Jiayi, and he can't remember the specific operation process.

Jiayi grinds the peeled bark and puts it in a large pool, then dilutes Extract No. 7 1,500 times and fills the pool. Then let the bark soak for the whole day. When I went to see it the next day, the bark had completely decomposed, and the entire pond had turned into a cloudy liquid.

Next, he had to filter all the liquid in this pool, and it could not be too clean, according to the requirements, he had to use a thousand meads of linen folded in two layers to filter, so that the result was a light brown cloudy liquid, like iced tea mixed with milk.

Eucommia gum is dissolved in this.

Then, Jiayi took out the matching separator, diluted it with water, and slowly mixed it into the liquid that dissolved Eucommia ulmoides gum. Gradually, strands of red silk appeared in the solution, like tiny red worms.

He used a tyed thing that looked like a large whisk to stir and stir in the pool water, and then all the separated rubber wires were wrapped around the large whisk, and the eucommia gum was separated.

This efficiency is really not high, 100 kilograms of bark can extract 5 or 6 kilograms of gum, in order to obtain enough gum, Jiayi spent more than a week to extract enough eucommia gum.

After extracting the eucommia gum, Jiayi didn't go to make tires at the first time, he first made some thin hoses, which were similar to the valve cores, and then made a slingshot!

That's right, it's a slingshot!

Moreover, he suddenly had a burst of inspiration and attached a fire-based strengthening circle to the slingshot, which was just an attempt to draw a picture, but he didn't expect it to succeed at one time. Then each projectile he shot was able to burst into a small flame.

It doesn't hurt much, but it's scary enough.

This should be the first piece of magic equipment he completed independently, although it didn't have any use.

Originally, he was not going to make pneumatic tires, but the solid tires were too heavy, and more importantly, the extraction of Eucommia gum was more troublesome than imagined, and the time spent was too great, and he was reluctant to use it all to make tires.

In the outer tire, he added carbon, as well as a fine cord to increase the anti-puncture ability, originally wanted to add steel wire to the outermost layer, but then it was too troublesome, forget it.

In order to install the tires on the tires, it took a lot of effort, the grooves of the wheels he originally made and the tires could not fit well, he needed a little adjustment, if it wasn't for magic, he would need to restart the wheels and tires.

Finally, a complete bike in Jiayi's mind was ready, and everything was perfect except for the lack of brakes and bells.

I guess so...
