After driving for most of the day during the day, tired is tired, tired and tired at the same time honed his driving skills, just tossed for a long time, after Xiahou Yue left, Su Ji, who went out alone and ate a good supper, went home casually watched the live broadcast of the game, and ran to sleep before eleven o'clock.

Eleven o'clock to bed is considered early or late, Su Ji doesn't know, anyway, he slept for almost eight hours, and woke up on time at seven o'clock the next day, got up after playing with his mobile phone for a while, and weighed himself before washing...... He's only 30 kilograms, which is hilarious.

It's not because his scale is broken, the scale is very low in addition to saying that he is not accurate, no matter what weight he weighs, the reason why he is not accurate is naturally because he can control his weight.

And this weight is the key to whether he can fly or not. Otherwise, with his real weight, at least 200 kilograms, at most 500 kilograms or more, no matter how big his wings are, he will not be able to fly.

Thinking of this, Su Ji couldn't wait to go to the factory to practice flying. Let's learn to fly first, and then wait until you can fly freely in the sky, and then consider whether innocent passers-by will be stupid when they see a big living person flapping their wings flying in the sky, and whether it will cause any big riots.

Su Ji hurriedly washed up and went out.

No matter how anxious you are, breakfast must be delicious, otherwise where you have the strength to move, you can't even lose weight without eating a full meal. Su Ji ate until eight o'clock, and rushed to the factory with a full meal and drink.

Quxin's husky is now kept in the factory, and the huge factory building is tens of thousands of square meters, no matter how much it makes trouble, it is said that it no longer wants to run outside. It woke up early, smelled Su Ji's scent from a distance, and stood behind the iron gate with its tail wagging to greet him.

"Long time no see." Su Ji was in a good mood today and raised his hand to greet the husky.

"You're still alive." The husky squealed, "You thought you were dead." ”

When Su Ji heard the husky's words, his face suddenly darkened, he shook his hands and turned into eagle claws and tiger paws, bared his teeth and grinned: "I'm not dead, but I think you're going to die." I'm here today to take your dog's life. ”

"Don't." The husky screamed and fled.

Of course Su Ji wouldn't bother with a dog, he snorted, his hands returned to normal, opened the iron door and walked into the factory, looked around, took off his coat to reveal his upper body, took a deep breath, and a pair of huge wings suddenly grew out of his shoulder blades.

I have to say that he is now in human form, and that pair of wings is far from being as big as the wings in dragon form, but it is not small anymore.

Now flap your wings.

Don't know if you can fly?

Except for the dust blown into the air by the wind brought out by his flapping wings, he himself stood firmly on the ground.

Why is this happening?

Su Ji looked at the wings on the left and right, flapped his wings, and knew why he couldn't fly.

His wings are long, he stands up straight and flapps his wings, and the wings are flapped in front of him, so that if he can fly, he will have a ghost, and if he wants to fly, he must flap his wings to the ground.

Su Ji ran to the workshop, bent down, now the wings are facing the ground, and then flap the wings hard to try...... He's already very hard, and if he doesn't move, he doesn't move, and he doesn't move.

Why don't you jump up and try it?

Just do it, Su Ji squatted on the ground, jumped up with a slight kick of his legs, and flapped his wings when he jumped to the highest place...... So, it's useless to flap your wings in front of you.

Su Ji tried again, this time remembering to bend down and flap his wings towards the ground.

The speed of the fall is even a little slow.

Until Shang Xialiu came to the factory at about ten o'clock, Su Ji still had no way to fly.

The authorities are confused, the bystanders are clear, Su Ji has never found a problem, but Shang Xialiu can easily see the problem.

"How much do you weigh now?" She asked.

"I measured it this morning, and it was 30 kilograms...... That's not a lot of weight, isn't it? ”

"That's that much in the morning, but it's not necessarily that much now."

"Then let's measure it again." Su Ji prepared to go to the laboratory building.

"Don't go to the laboratory building to measure, take it and measure it...... I'm going to get the scales. ”

"I'd better go get it." Su Ji couldn't wait to find out why he couldn't fly, he couldn't wait for Shang Xialiu to run slowly to the laboratory building to get the scale. He folded his wings, took a step several meters away, and brought the scale in three or two strokes.

Su Ji stood on the scale, looked down and said in surprise: "How did it become thirty-five kilograms?" ”

He stepped off the scale, then stood up again, and it showed thirty-five kilograms.

"Thirty-five kilograms is thirty-five kilograms...... Not much, isn't it? "The extinct Argentine eagle weighs 70 kilograms and has a wingspan of seven meters. I'm thirty-five kilograms, and the wingspan of the human form is not as good as that of the dragon form, but it's a lot, and it can definitely support me to fly. ”

He thought for a moment and said, "Why don't I try to change into dragon form?" ”

"Don't be in a hurry." Shang Xialiu said, "You can stand on the scale now and flap your wings." ”

"Okay."

Su Ji stood on the scale, bent over, looked at the weight, and was just about to flap his wings when he noticed that the number displayed on the scale under his feet increased wildly.

"What's going on?" He asked.

Shang Xialiu smiled bitterly: "I don't know if you ask." ”

Su Ji tried several times, he found a pattern, and said: "I found that as soon as I tense my body, I will gain weight, and as soon as I relax down, I will lose weight......"

"Is that why I can't fly?" He said to himself, "As long as you are ready to exert force, you will gain weight, and you will naturally not be able to fly when you gain weight...... I tried not to strain my body. ”

"You wait and try again." Shang Xialiu stopped Su Ji, "You can fan your wings again and show me." ”

"Okay." Su Ji flapped his wings, "What's the problem?" ”

Shang Xialiu put his hands in his pockets and took two steps at random: "Have you ever seen how birds fly?" ”

"Nope." Su Ji shook his head.

"The way you flapped your wings was too stiff." Shang Xialiu opened his hands as wings, "I see that when the eagle flies, its wings are spread when it flapps its wings downward, and when it flapps upwards, its wings shrink, and its feathers float up and down...... I can't tell you the specifics, just look at the video. ”

"No, that's not the point." She shook her head suddenly, "The reason why a bird can fly is because the top of the bird's wings are more curved than the bottom, and the curved wing shape can accelerate the flow of air, so that the air pressure is reduced, and finally when the air pressure above the bird's wings is less than below, it will be held up by the air." ”

"According to Bernoulli's equation, the faster the speed of the fluid, the lower the pressure, and another condition for taking off is to have speed."

"No bird can fly out of thin air. The bird needs to kick with its feet and then flap its wings and fly. Large birds must flap their wings while running before they can take off. Other birds, like swifts, have their feet so degraded that they can only cling to the façade, unable to walk or jump, so they can only stop at high places and rely on gravity to gain their initial speed......"

Shang Xialiu talked eloquently.

Su Ji was ignorant.
