After the bald old man heard what he said, he scolded him secretly, and said to him: "The research of the internal combustion engine stopped eight hundred years ago, although at that time the internal combustion engine was made into a racing car with ordinary materials, and the speed could barely reach the D level, but the durability and defense were not enough, and the parts had to be replaced if they couldn't run for a few kilometers, and the driver would be seriously injured or even killed in a car accident." ”

"With heavier D-class materials, you still have to maintain speed, and you can't run thousands of meters to replace parts, it's difficult! This condition is too difficult. I'm not sure about making a D car powered by an internal combustion engine, how confident do you have? It's really not good, my old face is out of the way, and I asked my former students and friends to test the pressure on the Qu family together, so that you two can cancel the gambling contract. The bald old man's words revealed the meaning of love.

Although the gambling contract under the witness of "Yuan" cannot be violated, otherwise it will be enforced.

However, if both parties agree to terminate the gambling contract, the gambling contract can be invalidated.

But Zhao Qingxiao didn't want to end like this, he hadn't forgotten how Qu Cai pitted the "Zhao Qingxiao" of this world this time, and he couldn't just forget it.

For Zhao Qingxiao, who has always been obsessed with learning in this world, this world is fair, loving and harmonious, but losing this opportunity to participate in the "Feitian" project stably collapsed his outlook on life and gave him the idea of suicide.

Perhaps it was because of this incident that he had some accidents in the room, which caused his consciousness to dissipate, so that Zhao Qingxiao, himself, came to this world, and said firmly to the bald old man: "Don't worry, mentor, I have studied internal combustion engines before, and there is still a month before gambling, I am confident." ”

"Are you really confident?" Seeing that he was so firm, the bald old man asked tentatively.

"Of course, eighty percent sure." Zhao Qingxiao said with a smile.

"Okay, sure enough, it's my student, ambitious, although I'm a little busy every day, but if you don't understand something, just leave a message and ask me, I will answer them for you one by one."

"I'll give you twenty-five days, if it's not done, I'll go to the people of the Qu family and talk to it." The bald old man said, and at this time, his personal butler prompt sounded, after all, as a rare A-level scientist in the Earth Federation, he had endless things to do every day.

"Mentor, you should be busy first, I will also prepare to build a car." Zhao Qingxiao hurriedly said.

"Alas, this child has always been obsessed with learning, and his nature is really pure and kind, and he is not willing to cause a little trouble to others." After turning off the projection communication, the bald old man let out a sigh, this disciple is good at everything, but he is dedicated to studying science and does not know the sinister nature of the human heart.

In the aisle in the middle of the workshop, Zhao Qingxiao met Zhuang Xueliu, she still didn't have a good temper with him, and said coldly: "Hmph, I got up so late, I was really a lazy, no wonder I was frozen from school." ”

"You still have the leisure to take care of me, don't you have to go to school today?" It's this stinky kid again, Zhao Qingxiao smiled, ignoring her words full of prejudice, after all, the girl in the frog pajamas wouldn't be too bad-hearted.

"Hmph, it's a holiday today." With that, she walked towards the inside of her workshop.

Ooh! Tsundere Lori,Rare variety.,If it was in his time,,This is going to be taken by the "goldfish guy" to see the "goldfish".。。

Yesterday I said that I ignored him at dinner, but today I took the initiative to talk to myself, just like the hotel where he used to work, women saw bullfrogs and said don't eat them, it's too disgusting, but after tasting a bite, it's not "really fragrant", women, ah.......

Zhao Qingxiao didn't have time to sigh, time is pressing, let's build your own car, the power system of the D-class racing car doesn't need to be taken care of by yourself, leaving built-in space, but the production of collision avoidance and appearance needs to be made by hand little by hand.

As for the attack power, forget it, what attack power do you want for the D-class car, the armor is high and then the acceleration impact, isn't this the attack power.

There are three points of racing rating: speed, defense, and attack, anyway, as long as the first two meet the standards, it is enough to select, and attack power is not a hard indicator, of course, your durability cannot be too bad.

Moreover, the cars below the A level cannot be equipped with any high-end weapons, and the low-level energy engine is not enough to provide the power of the light energy weapon, unless the speed is sacrificed and the volume is increased to load more source energy devices, but this loses speed and seems to be worth the loss.

As for loading old-fashioned gunpowder weapons, it takes up even more space, even if the speed of the super-large sniper rifle bullet is only 7200km/h, it can't keep up with the 10000km/h speed of other people's car A.

Instead, some people tried to load a few disposable small homing missiles and use them as a means of attack.

The disposable small tracking missile occupies a small space, has a tracking function, and is discarded on the spot after the launch has little impact on the speed of the car, but because this kind of missile has to be applied for by scientists above the C level, it is also rare.

The racing car can run to the extreme speed on the ground, and the precision requirements for each part are extremely high, and the appearance of a gap may cause the car to be destroyed and killed.

This requires scientists to modulate it alone, and in order to be more suitable for the "source force" of the owner, from a bump of the source force engine to the shape of the shell, plus the writing of the on-board intelligent assistance program, are all hand-built by the team of scientists.

Therefore, except for a small number of mass-produced D cars and "model cars" as models, each D car or higher has only one owner who is most suitable for him.

To make a racing car, you must first have a design drawing, Zhao Qingxiao called out the projection function of the personal butler, and began to use the projection facility to make the design of the racing car in his mind.

No one bothered him until the evening, and when he was thirsty and hungry to drink water, he ate some portable food, and all his energy was devoted to it.

Only the occasional sound of machinery starting next door, and the fading roar of racing cars on the track outside, reminded him of the passage of time.

Finally, when the personal butler reminded him that it was seven o'clock in the evening, he got the design of the car in the workshop.

"Today's goal has been achieved! Butler, project the image into the open space in front of me. Zhao Qingxiao wiped the sweat from his head and instructed his personal housekeeper.

Soon a racing car appeared in front of him, with a length, width and height of 5m, 2m, and 0.8m, and it looked about the size of a medium-sized truck except for its height.

The Earth Federation's racing cars are all made to be converted into spaceships, and there are not many restrictions on length, width and height, as long as you are not "too exaggerated", and the racing car is carried out according to the prescribed route, even if you fly in the sky, no one cares.

The exhaust system is in the middle of the rear of the car, and now it is a big hole, because there is no power system, so the inside is empty, and it looks like the previous F1 car, and it is a bit like the D car "Flame Warrior" in the QQ speed car, of course, this car has not been painted, full of metallic, and it doesn't look so good.

"Well, yes, you're called the Flame Frog. After turning around the projection, Zhao Qingxiao nodded with satisfaction.

Next tomorrow is to complete the production of the on-board intelligent program, the intelligent program of the car below the A class is very simple, just spend a lot of coins online, you can download a standard, and then add your own private settings, and the "internal combustion engine" he is going to make for the D car powered by the internal combustion engine, the intelligent program required, is even simpler.
