Ah Dong is indeed fine, but he is a little frightened.

Gu Nian was not interested in kites, but was interested in this cushion.

This thing feels a little inflatable!

Li Muyan is a cow!

This can be imagined, and the material used should be mixed with skin.

"Mm-hmm, let's give it a try next time it's windy!" Li Muyan was so excited that he wanted to stand up.

"Li Muyan, have you ever thought about flying without borrowing rope and human power? It's more convenient not to use a rope. Gu Nian circled around the cushion, then looked at the material of the big kite, thought about it, and said.

"No rope?" Li Muyan frowned.

"That's right! Just the material of your kite, really, you trust me. However, you'll have to wait until your leg heals and you can experiment on your own! Find a big mountain, jump down, you have light skills anyway. Gu Nian said.

"Gu Nian, I have reason to suspect that you are calling me to die!" Li Muyan glanced at her.

"Really, I don't lie to you. You make a big kite or something, don't you just want to experience the feeling of flying? I want to fly by myself, I don't need to do light work, I want to fly high, right? This material is really good, but you don't want to make it into the shape of a kite, I'll draw a shape for you, and you can figure it out yourself! Gu Nian said solemnly.

"Really?" Li Muyan still felt that Gu Nian wanted him to die.

"Really. Anyway, draw it for you, and you can figure it out for yourself. I used to hear people say that there are jugglers in the south of the Yangtze River, who can hold an umbrella and fall from a high place and land steadily. Gu Nian said again.

"Okay, come to my study and paint it for me!" Li Muyan nodded suspiciously.

Li Muyan's study is very large, equivalent to the area of several rooms of the Gu family combined.

There were a lot of gadgets inside, and Gu Xin and Gu Si couldn't look at it.

"Xinxin, Sisi, look at this puppy, if you turn it like this, it can go down to the ground by itself!" Li Han saw that Gu Xin and Gu Si's eyes were full of novelty, and took a gadget on the Bogu shelf.

Turn it around, put it on the ground, and sure enough, the puppy is gone on its own.

"Wow!" The sisters couldn't help but exclaim.

Gu Nian also looked over, yo, this kid has also learned to wind up!

The two sisters squatted together to play with the puppy.

Gu Nian sat down and drew a parachute shape for Li Muyan, and there was nothing else to say, too much, a professional talent like Li Muyan had to break the casserole and ask in the end, wouldn't she be exposed?

"Gu Nian, I used to think about a question, that is, Kong Ming Lantern can fly to the sky when it is lit, so can it be a large one, and Brother Hang's person can go to the sky?" Li Muyan looked at Gu Nianhua's parachute and suddenly asked.

Gu Nian was stunned, isn't that a hot air balloon?

This kid's brain is not usually active!

"Then do you know why Kong Ming's lantern can fly into the sky?" Gu Nian asked.

"Because there's a fire! I feel that this is related to the fact that wood can float in the water, and iron will sink in the water. The relationship between wood, iron and water should be like the air with fire and the air without fire. Li Muyan said.

Gu Nian raised his eyebrows, young man, not bad, if you continue, you can figure out the density, quality, and volume.

Moreover, Li Muyan's remarks are reasonable, Kong Ming Lantern is indeed because of the fire, which reduces the density of the air in the lamp, the gravity of the gas decreases, and the gravity is less than the buoyancy, so doesn't it soar?
