The Great Tang: God-level Bear Child: Chapter 130 : Make a hot air balloon, Li Chengfeng is going to fly?

Li Chengfeng took out a small watercolor pen and a small notebook, and began to write and draw on it.

He was still chanting: "The hot air balloon is the lift-off force generated by the hot air burned by the flame! So I have to calculate first, what is the weight of all of us plus the weight of the bamboo basket, and then calculate the absolute heat. How big do the balloons need to be."

"If you make it too small, it may not be able to fly, or it will fall down halfway through the flight!"

"In addition, the gauze of the hot air balloon needs to be airtight and airtight! So later, I need to get some pine oil to apply on it. In this way, the weight of the hot air balloon may be increased again! So It needs to be doubled in size from its original size, so that it will be ready for any danger!"

Li Chengfeng was talking in a broken voice, while Li Lizhi and Changsun Chong couldn't understand what he was talking about at all.

Several people looked confused, Zhang Sun Chong opened his mouth, wanting to ask, but in the end he closed his mouth obediently.

Because he knew that doing so would only make him appear less knowledgeable, so he was ridiculed by Princess Changle and the Eighth Prince.

"Okay, Miss Changle, Xiao Wu, you need to use needles and threads to sew a five-meter-long hot air balloon, and this hot air balloon needs a large area and a small diameter!"

"Ah? Is this so troublesome? What is a large area? What is a small caliber?"

Li Lizhi and Wu Xu looked confused.

Unexpectedly, Li Chengfeng's flying plan turned out to be so troublesome.

But it is also true, how can it be so easy to fly to the sky!

Immediately afterwards, Li Chengfeng drew the prototype of the hot air balloon in the notebook.

He tore off the page of paper, handed it to Li Lizhi, and said, "Sister Changle, Xiao Wu, you just follow the model above and start sewing!"

"Model? Let me see. It turns out that it is a big fan, and it needs to be stitched together to look like a ball?"

"By the way, do you know how to sew?"

Li Chengfeng frowned and asked.

Li Li smiled and said: "Of course, brother Feng'er, who do you look down on? As the princess of the Tang Dynasty, I am proficient in all kinds of piano, chess, calligraphy and painting, and needlework is naturally easy. This is my mother's childhood. *Learn what I'm learning, and say, this is a job that every lady must have!"

"Xiao Wu, can you do it?" Li Chengfeng turned to look at Wu Xu.

Wu Xu nodded slightly, and said: "Yes, I have sewed winter padded clothes for my mother, Eighth Prince, don't underestimate me!"

"Haha, that's good! Well, then you can start sewing according to the samples in this book!"

"Well, good Eighth Prince!"

Xiao Wu puffed his cheeks and tightly clenched his fists, as if to cheer himself up again.

Li Lizhi also took a deep breath, then picked up the needle and thread, and began to sew the hot air balloon.

Li Chengfeng was not idle either, he was using bamboo strips to weave the huge bamboo basket for carrying people.

Only Changsun Chong stood aside looking around, not knowing what to do.

Because he can't weave bamboo baskets or sew hot air balloons.

Changsun Chong came to Li Chenfeng's side and asked: "Here, the eighth prince, what's the matter, do you need the help of the minister?"

"you?"

Li Chengfeng wiped the sweat from his forehead, and said, "Oh, I have something to do, go and find me a big jar of pine oil, is there no problem?"

"Pine oil? Eighth Prince, what do you want pine oil for?"

"Don't ask, you don't understand what I said, anyway, you just do what I say! Could it be that we are busy here and you are idle here? Hurry up and do something for me!"

"Here, okay, okay! Xiaochen, let's go find pine oil!"

So, Changsun Chong ran out of Zhenwang's mansion in a panic.

Changsun Chong used his status and contacts in the palace to get some pine oil, which was no problem.

…

By the time Chang Sun Chong returned to the Zhenwang Mansion with a large jar of pine oil, it was already very late.

Eunuch Wu went to the imperial dining room and asked his servants to bring eight dishes and one soup, which should be enough for Li Chengfeng and Li Lizhi to eat together.

After a busy day, Li Chengfeng wiped the sweat from his forehead and said, "I'm so tired, sister, Xiao Wu, let's eat! We'll stop here tonight, let's continue tomorrow!"

"Alright Eighth Prince, let's come over here!"

Xiao Wu has also been busy all day, until night, her face is still flushed.

Li Lizhi was also sweating all over, and her clothes were soaked through.

"I'm back, Eighth Prince, I brought a big can of pine oil, can you see if it's enough!"

Chang Sun Chong came to Li Chengfeng's side in high spirits.

Li Chengfeng took the pine oil from Changsun Chong's hand, and said, "Enough is enough, a big jar full should be enough!"

"Okay, we can eat!"

"OK, all right!"

…

After dinner, Eunuch Wu suddenly came to Li Chengfeng's side, faltering, as if he wanted to say something, but he didn't dare to say it.

Li Chengfeng frowned, looked at Eunuch Wu, and said, "Speak up if you have anything to say, don't hesitate!"

"This, yes, the Eighth Prince!"

Eunuch Wu said: "The eighth prince, according to the servant's response, he said that Li Yuanba, the general behind the flattery mountain, wants to see you and play with you!"

"What? He wants to see me? Play with me?"

Li Chengfeng frowned tightly.

Eunuch Wu continued: "That's right, the eighth prince, according to the report of the servants, when he went to deliver the meal, where is your uncle still losing his temper! What should we do?"

"Hey, he, let's go and see him when I have time in the future!"

Regarding the matter of Li Yuanba, Li Chengfeng actually didn't really want to have anything to do with him.

But after all, Li Yuanba was his uncle, so Li Chengfeng felt that he should visit him if he had time in the future.

…

In the early morning of the next day, Li Chengfeng called Li Lizhi, Wu Xu and Changsun Chong to continue their flying plan.

"Chong Chong Chong, in three more days, our flying plan will be successful!"

"Well, good. I also seem to fly to the sky to see what the outside world is like!"

Li Lizhi smiled happily.

So three days later, a huge hot air balloon stood upright in the backyard of Prince Zhen's Mansion.

Li Chengfeng lit the pine oil, and the hot air balloon began to inflate due to the heat.

"Quick, come up quickly, if you don't come up, the hot air balloon will fly away!"

Li Chengfeng said anxiously.

"Okay, okay, we're coming up!"

Li Lizhi and Wu Xu quickly stepped onto the hot air balloon.

Chang Sun Chong hesitated for a while, because he was afraid that Li Chengfeng would trick him, but in the end, he gritted his teeth and jumped onto the hot air balloon.

Eunuch Wu stood aside, stomping his feet anxiously, and said, "Eighth prince, what are you going to do again? Could it be that you really want to fly to the sky?"
