Li Yu nodded and said, "Please continue..."

Fatty Naqu leaned over and bowed: "Let Xiaodan do the rest. We have thought about it together for a long time, and he still has to say the pros and cons, but the test load was indeed successful."

Li Yu took one look at this fat guy, and felt very fond of him. This guy was not arrogant, he knew how to advance and retreat, and he was also very worldly. It seemed that this guy was a talent that could be developed.

Xiaodan had just recovered from her fear, and waved her hands again and again and said modestly: "No, no, no, the success of this experiment is all due to this fat guy. This guy has successfully broken through many difficult problems.

.”

"You two, stop bragging and get down to business." After Li Yu finished speaking, Zhu Hongying, Yu Sisi and others were also focused on waiting for the outcome of the matter. If this lantern can really carry people into the sky, then

What a magical thing it would be.

Seeing that the young master was a little anxious, Xiaodan hurriedly explained: "Success is a success, but there are still a few problems. One is the fuel control problem. We have tried this countless times. It is really difficult to control it by one person.

It's not like two people can't carry it, so the load capacity is increased, but the amount of cargo will be reduced."

"This is not a problem. The flying lantern I asked you to make is not meant to carry one or two people, but at least five or six people. You can expand the surface of the lantern and then find an open area to increase fuel storage.

Quantity, then it won’t be a problem.”

Fatty Qu on the other side nodded and said, "Theoretically it is feasible."

"Then what else?"

Xiaodan responded: "The other thing is the direction. Once this thing flies into the sky, it has nothing to attach to. It is really a difficult problem to control the direction. We have tried several methods, but they are all very weak. To the greatest extent, it still depends on the

Control of wind direction.”

After thinking of this, Li Yu said: "You can imagine installing something similar to a rudder on the lantern to control the direction through wind resistance."

When Li Yu said this, Fatty Naqu concentrated his eyes, frowned in thought, and kept describing the problem of rudder control direction that Li Yu mentioned.

Seeing Fatty Naqu's thoughtful and studious look, Li Yu said patiently: "Just like in water, if you want to control the direction of the boat, you need to control the direction of the water by swinging it. The same principle is true on the ground.

The direction of movement depends on the friction between the wheels and the ground. But in the air, it only depends on the flow of air, that is, the flow of wind speed."

Xiaodan is also a person who studies hard. When Li Yu said this, he understood many terms, such as air, friction, rudder, etc., because Li Yu had told Xiaodan these things before, just for the better.

To create advanced things that recreate the famous era of the past as much as possible.

So after Li Yu finished speaking, Xiao Dan seemed to understand: "I understand. What Your Highness means is to install a bird-like wing or tail on the flying lantern to control it well through the resistance of the wind."

The direction of the lantern's flight is feasible."

The only problem left is the safety of the people in the lantern under defense and weightlessness. If the flying lantern is destroyed by the enemy's arrows or thrown stones, and the person falls from the top, he will be a god.

It will be smashed into seven or eight petals, but it will not be turned into meat. Even if the flying lantern is made, there will be no one to control it. Even if there is someone to control it, there must be someone who dares to sit on it.

At this time, Li Yu thought of things like parachutes, which require training before they are effective, and she was worried.

Fatty Qu saw Li Yu's thoughtful look and said, "Your Highness, do you have any ideas?"

Li Yu raised his head and smiled: "Actually, I don't have any idea. Is it possible that we can build something that can reduce the speed of descent, or something like an umbrella? That might work."

"I don't think so. What kind of umbrella has such a buffering power?" Fatty Qu obviously didn't believe it.

After all, you are not a person of the 21st century and have not been influenced by modern ideas. No matter how smart you are, you would not dare to think of such things.

Li Yu knew that it would be difficult for them to accept it for a while, so he said: "In this way, you can solve the problems such as direction control and fuel space, and I will take care of this."

After hearing what Li Yu said, Fatty Naqu and Xiaodan are also looking forward to you. They still can't accept such a magical thing, but under Li Yu's guidance, they have begun to slowly accept it, especially the flying lantern that can carry people.

, has now begun to enter the experimental stage, and has achieved a certain degree of success.

"Okay, now we act separately. Xiaodan, you and Mr. Qu are dedicated to solving these problems. You can first use the rope to control the flying lantern in the martial arts training ground, let the flying lantern rise slowly, and then test various encounters.

The problem, maybe there are many things above that we haven't considered."

I have something important to do now. You can go your own way.

After saying that, Fatty Naqu, Xiaodan, and Arnost hurried to the testing ground and started to continue working on the flying lantern.

The rest of the people looked at Li Yu, wondering what he was going to say.

"Liu Gong, take some of your people with you, along with Senior Fan and Hong'er. You can continue to explore the road and see if there are any new discoveries."

"I know Young Master." After bowing down and paying homage, Liu Kui led Zhu Hongying, Fan San and others into the underground secret room to continue exploring the route.

"Zhao Yong is injured and cannot move for the time being. Xiucai, you will take Zhao Yong's place and train the remaining newcomers. Remember, don't relax. You must train all their fierceness in me."

"Ling'er, Liu Zhen has gone to Yanyu Manor, and you will be the one to teach the remaining students."

After Wan Ling'er and Xiucai heard this, they went about their business.

"Erhan, Fan Hu, you two come with me. Let's go interrogate Hu Dayou and Pei Yuanqing together to see if we can come up with something new."

"Where are they being held?"

"Still in the same place, young master." Fan Hu said from the side.

After saying that, Fan Hu took the lead, followed closely by Li Yu and Er Han, and after a while, they came to the secret room in the back garden of the Prince's Mansion.

As soon as they entered, the two special forces members came to greet Li Yu. Li Yu signaled that there was no need to be polite, and then looked at the two men, Hu Dayou and Pei Yuanqing, who were tied like rice dumplings.

The two of them also saw Li Yu, and Pei Yuanqing was fine. There weren't many scars on his face, just some scratches, which didn't seem to be a big problem.

Li Yu knew that since Pei Yuanqing, Ma Saiyuan, Lian Shaoan, Qiu Shuchen and Hu Dayou all came to his mansion to serve as an academy and became servants, someone must have ordered them. Although the five of them have gone to the third

, but the real core figure must be Hu Dayou, because everyone seems to be controlled by this person.
