With the help of Shang Xialiu's theory, Su Ji successfully figured out that flying is never a simple thing, and it is not something that a person can fly by suddenly growing a pair of wings and simply flapping it.

"If you say a word, it's better than reading a book for ten years."

"Okay, I kind of know how to do it."

"First of all, you have to learn to control your weight, because if you weigh too much, you will definitely not be able to fly. And then you can't flap your wings as simply and stiffly as you used to...... There is skill in flapping your wings. And you can't fly on the spot, you must accelerate to fly, you need an acceleration. ”

"Anything else you'd like to add?"

Su Ji said all his understanding.

"That's pretty much it."

"But you're wrong." Shang Xialiu paused and said, "It can only be said that most birds must fly forward, not all birds must fly forward. Hummingbirds will be able to hover in the sky and even fly backwards. ”

"I know hummingbirds, but I've never seen them." Su Ji recalled the hummingbird he learned from various sources, a small one, probably the size of an ordinary person's thumb, "I knew it could hover in the air, I really didn't know that it could fly upside down." ”

Shang Xialiu raised his hand, moved his forearms, moved his wrists, and said: "The hummingbird has a super high flight ability that ordinary birds do not have, mainly relying on its light weight, high frequency of wing swings, flexible shoulder joints, and super sense of balance. ”

Su Ji looked at his wings, the hummingbird's wings belonged to the half-moon wings, and his wings belonged to the rising wings, and said, "My wings definitely can't fly like a hummingbird." ”

"Who knows...... You are a dragon and anything is possible. Shang Xialiu said and suddenly walked to Su Ji's side and observed his wing roots.

"What are you looking at?" Su Ji asked.

"I feel that the structure of the wings is very similar to our arms, and if I had to do it, I would be able to make a lot of complicated movements."

Su Ji moved his arms and wings again, and said, "It feels a bit like." ”

"In that case, when you learn to fly, you can try the hummingbird way of flying."

"Yes."

"Hummingbirds can hover, Andean vultures can fly for five hours without flapping their wings once, and the use of wings is a great science." Shang Xialiu showed a regretful expression, "It's a pity that humans don't have wings, and there is no way to explore the use of wings in depth, so we can only rely on you." ”

Su Ji clenched his fists: "I will work hard." ”

"Speaking of flying...... It's still a dragonfly. Shang Xialiu said with emotion, "Dragonflies can fly 360 degrees, hover in the air, and fly in any direction at any time." Obviously it is so small, the flight speed is not slow at all, and it can change from a hovering state to a high-speed flight state in a very short time, and the endurance is also strong...... There is a species of thin-winged dragonfly that can cross the Pacific Ocean. ”

Shang Xialiu talked about dragonflies, Su Ji suddenly remembered an interesting thing and asked, "It is said that the aircraft in-flight refueling technology is a very powerful technology?" ”

"Sort of...... What do you want to say? ”

"What I want to say is," Su Ji said with a smile on his chest with his hands, "such a powerful technique is not worth mentioning compared to the flying skills of a dragonfly." Dragonflies can mate in the air, and even fly together at high speed to avoid attacks...... I caught dragonflies when I was a kid, but I don't dare to catch them anymore. ”

Su Ji found that Shang Xialiu was looking at him with a strange gaze, and coughed: "No matter how powerful the dragonfly is, its appearance is too good...... Okay, I'm ready to practice flying. ”

Su Ji ran away, found a place to sit, took out his phone and rummaged through the video, he wanted to see how the eagle's wings flapped when it flew.

He found the video, and when he looked at it, he felt ashamed of himself.

Compared with the eagle's action of flapping its wings when flying, the action is quite complicated, it expands when it flapps its wings downward, and shrinks when it flapps its wings upwards, and the action of flapping its wings is not straight, like a line that fluctuates up and down.

Su Ji held the mobile phone in both hands and played the video over and over again, and the pair of wings behind him kept imitating the action of the eagle flapping its wings, imitating while watching, slowly walking around the huge workshop for many laps, definitely more than an hour, and finally felt that it was okay.

Su Ji didn't flap his wings on the spot this time, he ran to the workshop and jumped up with a run......

Why can't I remember, I can't remember to bend down, it's useless to flap my wings forward, you have to flap my wings towards the ground. In particular, you can't be nervous, as if you are nervous, you will gain weight, and when you are nervous, you will forget that you have just imitated the movement of the eagle's wings.

One more time.

Su Ji didn't forget to bend over this time, and sure enough, he was still a little nervous, at least he opened his wings and flapped well, and the speed of his fall seemed to have decreased.

Come again and again.

Su Ji fell from the air this time. Although he fell from several meters in the air, let alone a fracture, there were no abrasions on his body. I have to say that his physical fitness is too strong now.

Really, can you get worse and worse with practice?

Shang Xialiu watched Su Ji practice flying the whole time, she couldn't watch it, and said, "Why do you have to jump?" Even if you don't fall and get hurt, won't it hurt to fall? You only need to accelerate and run, and it is enough to flap your wings, and you can do it without jumping. ”

Su Ji's eyes widened when he heard Shang Xialiu's words, and he asked, "Is it okay if you don't jump?" ”

"When did I say I had to jump?"

Su Ji thought for a while and said, "It seems that I haven't said it...... So why should I jump. ”

"I don't know if you ask."

"Because when I was a kid, I always had to jump to learn how to fly. Causing now to subconsciously jump. ”

Shang Xialiu didn't speak, shrugged his shoulders.

Su Ji didn't jump anymore, but spread his wings and ran on the ground, flapping his wings while speeding up, and then he didn't have to jump up and didn't have to worry about falling, and he wasn't so nervous.

After running from one end to another, and then from that end to this end, after running back and forth several times, Su Ji gradually found a little feeling, and finally retracted his legs after a flap of his wings, and the whole person did not fall to the ground, but glided four or five meters forward.

Once you have a successful experience, it is enough to learn and learn well.

Su Ji can gradually fly, the problem now is that he can't fly high, not because the height of the workshop limits the height of his flight, the main thing is that he has to fly while moving forward, and the workshop is so big, he has to stop before he flies.

Anyway, he can fly now, that's enough.
