Fortunately, Xiaocheng recovered his mind in the face of danger and immediately realized his current situation. He hurriedly used all his strength to pull the joystick and tried to change the direction of the aircraft.

But unexpected things happened. The joystick of the aircraft didn't listen to it at all. Even if Xiaocheng used his strength to sway it, he could not shake it at all. He was about to hit the big tree not far away, so he could only squat down in fear and hand over his life to luck.

Swish! Swish! Swish!

Bang! Bang! Bang! Bang!

The fan leaves kept breaking the branches and finally hit the trunk hard. Due to the effect of inertia, the fan leaves suddenly broke and then flew out around.

"Xiaocheng, if you catch it, you must be careful."

Li Zhi saw the disciple's actions clearly below. It was not because he had improper operation that caused such consequences, but because there were quality problems in the aircraft itself, which led to such an accident.

Fortunately, the big tree was thick enough. The aircraft hit the trunk hard, which only caused the tree to vibrate violently, falling leaves all over the ground, and then the wreckage of the aircraft fell completely on the tree branches, without any movement.

"Xiaocheng, how are you? Is there anything wrong?"

Li Zhi ran quickly to the big tree, looked up at the wreckage on the tree branch, and shouted loudly. If he had known that such a problem would occur, he should have gone up to experiment himself, rather than handing it over to Xiaocheng who had no experience.

"Teacher, I'm sorry, I broke the aircraft."

God is still very kind to Xiaocheng. Such a big accident only cuts a few small holes in his little face, and the rest did not suffer any harm.

"It doesn't matter. It's fine. You're fine if you're okay. Now you can try it. Can your body move? Are you feeling uncomfortable?"

Li Zhi looked at Xiaocheng with concern below, fearing that his body would be injured. As for the aircraft, he didn't care about it at all. As long as there was nothing wrong with people, he naturally had plenty of time to redevelop the aircraft.

"Teacher, I'm fine, but why does this aircraft happen? I've obviously tried to change the direction, so why is it useless at all?"

Xiaocheng climbed down the tree, looking very upset, and blamed himself, putting all his mistakes on himself.

"It's not your business, it's because there's a problem with the transmission shaft that transmits power below. It should be because the hardness of the material is not up to standard, which causes the joystick to lose control."

After seeing that Xiaocheng was not seriously injured, Li Zhi breathed a sigh of relief, recalled the previous incident, and then made his own inference.

"Teacher, this aircraft is really not suitable for flying by relying on manpower. It's just a short time before I was about to lose my strength. If I study other powers to replace manpower, that would be great."

The thing just now seemed very dangerous, but in fact, Xiaocheng didn't have much fear in his heart. At most, he was just a little scared, so he didn't delay his enthusiasm for invention at all.

"This is also impossible. With current technology, it is simply impossible to invent such a thing. It is a good thing to have such an idea. How to practice it depends on yourself."

Li Zhi was very pleased to have such an idea. It is worth teaching him so long that the modern equipment of later generations will not be performed here in a short while, and he will still need a lot of time.

Xiaocheng nodded gently. He knew that he could not leave all the difficulties to the teacher to deal with. Although he had his own independent idea, how hard it would be to join the practice, which made him feel like he was unable to start.

With current technology, the engine on a car can serve as a power device, but it is impossible to load that big guy onto the aircraft. Before the aircraft is ready for takeoff, the power of the engine will destroy the aircraft.

"Teacher, can you change the space you ride, and two people ride at the same time, and then control the flight trajectory of the aircraft separately. If anyone is tired in the middle, he can have a rest time."

The power device cannot be developed in a short time. The previous aircraft can be said to be half successful, at least it has been successfully flying for a while.

"Okay, if two people go up together, they can at least greatly improve safety and at least ensure safe landing before losing power."

Although this is a relatively stupid method, it is still good to solve the current dilemma. Anyway, he has no good suggestions now, so it is better to try it.

"Teacher, what should I do about this thing? It seems that there is no place to continue using it."

If I had thought of this suggestion earlier, maybe the aircraft before would not have crashed. Looking at the wreckage on the tree branches, Xiaocheng felt very sad.

It was another sleepless night, and Li Zhi was still immersed in the world of drawings. After a day and night, he finally outlined the improved version of the aircraft drawings. Overall, it was no different from the previous aircraft, but the internal structure was definitely earth-shaking.

The seats of the two people have a pair of pedals, which facilitates the two of them to work together, so as to keep the aircraft stable and provide time for rest for their companions.

Most of the materials of the aircraft before were made of high-quality wood, but this time, Li Zhi changed his original intention and replaced all the vulnerable change inside with iron tools. Although the weight of the aircraft increased, it greatly reduced its risks.

In a blink of an eye, half a month passed. In the manor, the two of them gathered together every day to discuss installation issues. Even Li Zhi could find that in the past few days, Xiaocheng's steps were very big.

"Teacher, we will definitely succeed this time."

It took a lot of effort to assemble this new aircraft. Xiao Cheng gently stroked it, and his heart was filled with satisfaction.

In order to ensure flight safety, Li Zhi carefully checked it up and down several times, and after confirming that there were no missing, he signaled Xiaocheng to go up and they tested the flight together.

With previous operating experience, the aircraft quickly flew over the manor. Xiaocheng could clearly feel that this time the aircraft was much smoother than the previous one.

"It feels okay, go out and have a walk."

Although this thing is not fast, the condescending feeling is absolutely extremely comfortable. Li Zhi pointed to the distance and gave an order directly.

"Good!"

Xiaocheng agreed excitedly and pushed the joystick directly, and the aircraft flew smoothly into Linyi City. He wanted to show his face on it.
Chapter completed!
