Although Chu Yun has never experienced the real glider, she has seen a lot in TV movies. There are many unreasonable aspects of Lesa, a glider that relies heavily on magic. She can avoid falling to death while gliding. It can only be said that she has strong magic power.

"You! What do you mean! Don't buy anything you don't want to buy. Why do you insult the lady's work?" Ella, who had not spoken yet, could no longer help it.

Miss Lesa is noble but approachable to herself like a sister, and is also a talented magician and genius alchemist. She is used to resist her family's engagement. She is an idol in Ella's mind and cannot be desecrated by anyone.

"Wait for Ella, let me hear what he said first. If I come to cause trouble, I will teach him a lesson myself." Lesa comforted Ella's little emotion.

She knew that her works were inadequate, but no one was willing to discuss and study them with her, and there were very few such products on the market that could not be referenced.

Although the man in front of him was rude, she didn't know why she always felt that Chu Yun was trustworthy.

This is definitely not simply because Chu Yun is handsome, but perhaps it is related to the unique temperament he exudes.

"I'm very interested in this product. I can give you some advice if you can improve the existing product and satisfy me. I can provide you with the skin of the Thunderwater Ray, and of course you need to give me a finished product at that time."

"If it were just a glider of this level, to be honest, I think it was also a violent desperation." Chu Yun continued to express his thoughts, without estimating Lesha's feelings at all.

If the other party can't even accept this criticism, there is nothing to say. He doesn't need this kind of semi-finished product either.

Lesa took a deep breath and resisted the urge to release the wind blade to cut the man in front of her into flesh.

"Can you tell me where this 'fly wing' is not done well?" Lesa asked gritted her teeth, especially the tone of the word 'fly wing'.

The other party glided at once and made her very dissatisfied.

Chu Yun thought about how to explain to her that the civilization of this world is not backward, but its development direction is different from the earth, so the focus is also different. The addition of the science and technology tree is seriously biased towards science and technology.

"Your glider imitates bird wings, but how can you copy and use your flying principle completely different from it?"

Lesa's current flying wings are two pairs of wings on the left and right. In fact, Chu Yun wants to call it a parachute, but he just relies on the wind-type magic array to force the flying wings to glide.

In fact, humans on Earth had similar ideas when they first started to study flight.

"Have you seen a ship?"

"Of course I've seen it, but what does this have to do with the flying wing?" Lesa was a little puzzled.

"Have you ever studied the shape and structure of the ship?"

"The shape...it seems like the front of the ship is usually with angles?"

Chu Yun nodded: "This shape can allow the ship to break through the water flow better, and the same principle applies to the air."

As he said that, Chu Yun came to the table and found a piece of white paper. Laisha thought Chu Yun wanted to draw a picture and hand him a pen. However, Chu Yun folded the paper and soon a paper plane appeared in Chu Yun's hand.

The front of the paper plane has angles like the ship, which corresponds to what he just explained.

Then Chu Yun threw his hand gently, and the paper plane flew out the door with a graceful curve. A breeze blew, and the height of the paper plane not only did not decrease but flew higher, but flew dozens of meters away before slowly landing on the road puddle.

Lesa widened her eyes, and in Ella's puzzled gaze, she rushed out of the door as if crazy and carefully picked up the paper plane that fell on the water beach.

"What a magical thing, why can paper fly so far? Is it magic?"

"No, he used my paper just now, and there was no magic fluctuation."

Lesha tried to throw out the paper plane as Chu Yun did just now. Although it was dipped in some water, the paper plane still flew freely in the air.

Lesha came to Chu Yun thoughtfully. This time her attitude improved a lot: "Mr. Chu Yun, are you also an alchemist? What magic principle is you just using?"

Chu Yun was a little proud when he saw the other party's attitude change. After all, this was the ancestral method of folding paper airplanes, and he won the championship in the kindergarten airplane competition.

"This is not a magic principle, but a rule that takes advantage of events and all things. You can call this science 'physics'."

"Physics is really a great knowledge. If I build my flying wings in this structure, I can save a lot of magic circles!" Lesha really wanted to ask more physics knowledge, but she knew that there was such precious knowledge that the other party would not disclose too much.

"Although this model can fly farther, it is not suitable for manned people, and there are still great improvements." Chu Yun found another piece of paper and "Give me your pen."

"Okay, OK." Lesa was like an obedient and good student, obediently handing over her beloved bone pen made of immortal bird feathers.

Chu Yun found a simple ruler to draw with perspective method, presenting the flying wings on the earth in a very three-dimensional way in front of Lesha. Lesha was very interested in this method of drawing, but she focused more on the construction of the flying wings.

"This is a kind of equipment that can fly and slide from a high place even if you don't borrow magic. It consists of four parts: tower, keel, tripod, and suspenders, and each part is connected by a steel cable. As long as there is a suitable hillside, 5-6 steps against the wind, you can soar in the sky. When it moves against the air, lift and resistance are generated on the wings due to the action of the air, and therefore it can carry a man to take off for gliding and flying..."

Chu Yun didn't know if he was right or not. He was not professional. However, it was enough to explain to Lesha. She nodded in a daze, and the glitter in her eyes became brighter and brighter.

"These are just triangular gliders made of ordinary materials without magic. If you can add magic to this, you can consider providing you with the material."

Lesha is a girl who is getting more and more courageous. She is not depressed by the failure of her work. After hearing Chu Yun's patient explanation, she seemed to be the door to the new world being opened.

"I'll start improving right away! It will definitely succeed this time!"

"Thank you, thank you so much!" Lesha saw hope and won the dawn, so she was very grateful to Chu Yun.

"Don't worry, if the product is really successful, I will put your name first in the alchemy patent at that time!" Lesa said solemnly.

Chu Yun smiled slightly and left the workshop without comment.
