Su Ji respected Qu Xin's thoughts, although she didn't know why, but thinking of Shang Xialiu's bad character, she could probably guess why, anyway, she didn't want Shang Xialiu to know that their relationship was advancing by leaps and bounds, and he was willing to help hide it.

Anyway, with the appearance of Shang Xialiu, Su Ji had no way to bully Qu Xin anymore.

It's too much, in fact, he didn't plan to bully Qu Xin in the first place, it's almost fine. Although Xiahou Yue instigated him to push down Qu Xin in one go, even Shang Xialiu did not let go, killing two birds with one stone. That's because she has nothing to do with herself, and it's a big deal to watch the excitement, and he can't do it to that extent.

Shang Xialiu had just asked him why he was here, and the excuse he made for him to appear here was to come and see how the video of her flight in search of various birds, bats, and insects was going.

Shang Xialiu's answer was that he had found a lot, and in order not to show anything unusual, he naturally followed Shang Xialiu to her room to watch the video.

You can't go directly, you have to wait five minutes before going.

"She's definitely going to clean up the room." Qu Xin looked at Shang Xialiu's back as he disappeared on the stairs and said affirmatively. "Otherwise, I wouldn't dare let you go to her room."

"Is her room usually messy?" Su Ji asked.

"Messy."

"Is it messier than your room?"

"It's a lot of chaos."

"That should be pretty messy...... Five minutes shouldn't be enough. ”

"I always feel like something is wrong with your words."

"You're thinking too much."

Shang Xialiu finally cleaned up the room and stood on the top of the stairs and told Su Ji to go upstairs.

Shang Xialiu's room was located on the second floor of the villa, just opposite Qu Xin's room.

Su Ji remembered that when she visited Qu Xin's villa before, the room where Shang Xialiu lived now was still an empty room, and there was nothing, but as she moved in, it suddenly became extra full, with more beds, wardrobes, dressers, bedside tables and an oversized computer desk, a printer, a desktop computer and a laptop.

Looking around, I didn't find any problems, but I smelled it, there were too many messy smells. I didn't come here today to complain about Shang Xialiu's room, so Su Ji didn't speak.

"How much does your computer chair cost?"

"I don't remember thousands, either."

"It's not the same when it's expensive."

Su Ji, who was sitting in front of the computer, was not in a hurry to watch the video, first cared about the computer chair, and then about the computer configuration, and even the computer system.

Now start watching the video.

Su Ji sat in front of the computer and watched the video intently, and the videos collected by Shang Xialiu from various channels about the flight of various birds, insects, and bats could help him master the use of wings and save a lot of time in groping for the use of wings.

Shang Xialiu stood next to him and explained.

The first thing they saw was a video of a hummingbird flying.

Shang Xialiu explained while gesturing: "When ordinary birds fly, their wings are waved up and down, and the wings of birds are not completely parallel to the ground when flying, but at an angle, so waving their wings up and down can not only make the bird fly, but also produce the force to move forward......

"The hummingbird's wings are a little different from other birds, its shoulder joint, that is, the joint that connects the wings, is the most flexible among birds, so it can change its wings at any angle according to its own flight needs......" She looked at Su Ji's shoulder, "I looked, your shoulder joint is also quite flexible......

Su Ji subconsciously twisted his neck, wanting to look at his shoulder. The dragon form has a long neck and can barely do that kind of thing, while the human form is delusional.

"When it needs to hover, the hummingbird will keep its body as perpendicular to the ground as possible, and then wave its wings back and forth instead...... There must be an angle of downward roll, otherwise there is no upward lift, at this time you only need to find the balance point of lift and gravity and the front and back forces to achieve hovering......"

"If you need to rise vertically, you just need to adjust the frequency of the wings. The same is true for flying backwards, adjust the power of the wings swinging back and forth, and increase the force of the forward swing, and you can complete the inverted flight......"

Watch a video.

Su Ji fully understood the way hummingbirds used their wings when flying, and now he had a concept of the use of wings, and he knew at a glance that he had done similar movements, looking around, if it weren't for Shang Xialiu's room being too small to support him to open his wings, he really wanted to open his wings and try.

"I remember that there are no hummingbirds in China." Su Ji asked suddenly.

If you visit hummingbirds in China, you can buy hummingbirds in the flower and bird market, and he wants to see hummingbirds flying in person.

"You remember correctly, there are no hummingbirds in the country, and hummingbirds all live in Central and South America." Shang Xialiu said, "There are only hummingbirds and eagle moths in China, which look very similar to hummingbirds, but they are a kind of moth." There are also sunbirds, which are similar in size to hummingbirds, can also hover, like nectar, but cannot fly backwards. ”

Su Ji thought for a while, retreated and asked, "Where are the sunbirds?" ”

"Lin Cheng should have it."

"Is there one in Lin Cheng, why have I never seen it."

"I don't know if you ask."

Su Ji's original purpose was to come to Qu Xin to cultivate his feelings, and he was going to watch the meaning of the video and forget it, but who knew that he would be addicted to it all of a sudden.

After all, his goal has never been to open a harem, but to become a dragon.

Anyway, this morning, Su Ji stayed in Shang Xialiu's room, and read all the videos she collected in one go—she only started looking for them this morning, and she really didn't find many videos—and learned a lot of knowledge about flying with wings.

Drum wings are the basic way for birds to fly. When birds fly, they are often accompanied by varying degrees of gliding after the drums have gained sufficient altitude and thrust. Final Soaring is a way for birds to gain energy from the air current, without muscle contractions to gain momentum, and consumes the least amount of energy.

Small birds often fly with their wings between their wings, flapping their wings rapidly, with high flapping frequency and little change in shape. When a big bird flies, also pay attention to the movement of the body and tail. Their bodies are not fixed in the process of flying, but move up and down, with the wings moving in opposite directions to their bodies, and their tails moving in the same direction as their wings.

Albatross also has a unique way of flying called dynamic gliding. This type of flight refers to the fact that they constantly change the angle and attitude of the wings during flight, so that they can get more lift and power in the wind current, and maintain their flight.

His wings are feathered wings, which are very different from insect wings, and there is really no need to refer to the way insects fly.

Next, Su Ji, who had learned a lot of theoretical knowledge in the morning, rarely took a nap in the afternoon and stayed in the factory to practice flying. His goal is to learn how to hover, and then think about vertical ascent, landing, and reversing.

After an afternoon of practice, I can barely hover, hovering and hovering.

I have to say that hovering must flap his wings frequently, it's strange and tiring, after practicing for an afternoon, Su Ji, who went home after dinner, fell down on the sofa and didn't want to move, so he lay down for half an hour first. Even if Xiahou Yue came over to see him, he just glanced at her.

"How's it going?" Xiahou Yue looked for him for nothing else, just to understand the progress of him and Qu Xin.

Su Ji replied: "It's progressing well, it's almost time to hover in the air." ”

Xiahou Yue figured out what Su Ji had done that day.

She narrowed her eyes, thinking to herself if she was too impulsive, she shouldn't just refuse Shang Xialiu like that, it should be too late to save Shang Xialiu now, and sure enough, she should still catch it with both hands.
