The farmers in Dafengtai quickly found four cows.

The plane had to be pulled by oxen to the proving ground.

And every plane is relatively heavy, and it is definitely not possible to pull it with a steam car, the torque of the steam car is too small, and the vulgar force is not great.

The entire Kyushu Academy of Sciences was in a sensation, and everyone came out to watch these two big guys.

Many people followed along, and at the same time discussed:

"It's so big...... Can you fly? ”

"It's not like an airship. Hydrogen is added to the airship, and the bigger it is, the more lift it has. These two guys turned out to be made of wood and steel pipes, why do I look so unreliable? ”

"yes, look at that...... It's still broken with a steel wire, and it doesn't look strong. ”

"Can this thing fly? What are you kidding, it's not like you can fly with wings. ”

"I think I can definitely fly."

"What basis do you have?"

"Because it has wings, and this wing is still big."

"Hahaha, I don't think it can fly."

"Why?"

"Because the dead weight is too big. Its principle is definitely correct, according to this principle, theoretically there is no problem with flying. But it's too heavy, this self-weight ...... It takes tons of thrust to get it off, right? ”

“……”

Some people in the Kyushu Academy of Sciences recognize it, and some don't.

But in any case, they are all intellectuals who are engaged in science, and the opinions they say are also well-founded.

But when the four cows pulled the two big guys out of the Kyushu Academy of Sciences, Dafengtai and Laoshan County exploded.

Countless residents, foreign tourists, foreign scientists, foreign scientists, foreign tourists flocked to it. The roads were blocked tightly, and they all stared at it with wide eyes.

Their comments, however, don't have so many scientific opinions.

"They say it's a flying machine? Can this fly? Isn't that right...... It's made of wood, where does it get the hydrogen from? ”

"You don't need hydrogen to fly. You see hot air balloons, isn't it. But...... Is there a blowtorch in it, is it necessary to set up a fire? ”

"This shape...... It looks like it can't fly. ”

"It's something that looks like wings, but I think it's too unreliable. Look at that, it's even more bizarre, and there are two layers of wings, hahaha. ”

"This is supposed to be an imitation of the bird. But I've never seen a bird with two layers of wings. ”

"Could it be...... Can a bird fly higher with two layers of wings? ”

"I see. I finally got it. It can definitely fly. 、”

"Why are you so sure?"

"You see there's a seat there, you see there's a gap in the wings, which means the wings can move. I suspect it's an imitation of a bird, and when a person gets into it, he flaps his wings and flies into the sky. ：”

"Makes sense."

"Tsk, how hard does it take to flap these two wings."

“……”

Liu Jinghong looked at the people around him with some concern, and said, "Master Li, do you want to cover them with a canvas?" And then go to a secret experiment where no one is? After all, this is also a secret of our Kyushu Academy of Sciences. ”

Li Zhen shook his head and said with a smile: "No." If they want to see it, let them see it, and everyone will develop together, which is the right way. ”

"But...... There are a lot of foreign scientists among them. They may be able to see the doorway. ”

Li Zhen couldn't help laughing, looking at the foreigners around him, with a thick look of disdain in his eyes: "I want to reach our current level." Let's start with an industrialized society. Flying machines are not something that you can build by looking at a shape, the structure and materials of the wings alone are enough for them to study for a long time. By the time they have figured these things out, we may have successfully entered the blue sky, or even developed the second or third generation. ”

After speaking, Li Zhen said earnestly:

"Shocking. Don't always try to grab it. Don't always think about taking all the benefits, you eat meat, you have to leave a soup for others, this is the right way. One step ahead of the world, two steps, can, and great. But if you are too far ahead of the world, then everyone will see you as an enemy, because by then you have already stood out from the crowd. ”

Liu Jinghong glanced at Li Zhen a little strangely, and it was difficult to understand the meaning of Li Zhen's words for the time being.

Li Zhen and the others walked forward in a steam car, and the villagers behind drove cattle and dragged two planes to follow.

And then there are a dense crowd of residents, foreigners, tourists, and scientists who come to see the excitement of the neighborhood.

They all want to see if this weird guy can really fly into the sky.

Before the advent of hot air balloons, everyone thought that if humans wanted to fly into the sky, they needed to make wings like birds and flapp.

But after the hot air balloon came out, the concept was subverted, and everyone felt it. Oh, it turns out that if you want to fly into the sky, you need heat. You don't need wings, but you have to use a blowtorch.

After the paraglider comes out. Everyone suddenly realized that if they wanted to fly into the sky, they could do it without a blowtorch. But you need to jump down from a high altitude and can only glide.

But after the advent of two-stroke powered paragliding, everyone saw a flat take-off. Everyone felt that if they wanted to fly into the sky, they needed to have a flying machine overhead and hang people.

After the appearance of the airship, everyone thought that hydrogen must be available to fly into the sky.

As the Kyushu Academy of Sciences continues to refresh everyone's concept, no one thinks that wings can fly anymore.

At this time, people feel that wings are not needed to fly. Flying machines also don't need to have wings.

Now, after the appearance of the most traditional flying machine, the architecture of the glider. On the contrary, no one believed that it could fly.

Because before that, everyone already thought: you don't need wings to fly. It is impossible for human beings to flap their wings to the sky.

And airplanes have wings. has wings, and everyone takes it for granted that it must be flapped and flying.

I know what it is, but I don't know why. Blind obedience, superstition.

This is the most popular and normal concept in the world.

They are not scientists, and Li Zhen does not find their ideas pedantic. But in fact, many intellectuals and scientists in New Kyushu who followed the crowd to see the excitement were even more suspicious.

A said, "Is a man standing in it flapping his two great wings?" How does this fan move, who has so much strength. ”

B said, "It should be the principle of levers used inside, and it doesn't take much effort to be able to flap those two wings." The mechanics of the Kyushu Academy of Sciences are well developed. ”

A said again, "You see, the wings are not solid, but as if they were covered with a canvas over a frame." ”

Yi Yi patted his head: "Ah, I see." It's the two wings filled with hydrogen, haha, it must be like this. Actually, the principle is still the airship, but it has changed shape. They poured hydrogen into these two wings. ”

"You're a genius!" ”
