The fuel for the hot air balloon is a kind of fluorescent coal, which is a rare ore unique to Ortuno - long burning stone. It is a highly efficient fuel, often used by the royal family for lighting, and is rare even in the imperial capital. If it weren't for Nolan's business dealings with Ortuno, Wayne doesn't know how long it would be before he could see the ore.

As soon as the Northwest nobles were blockaded this time, the dwarven merchants of Nolan were a little difficult. Consumption is high, and it is difficult to go back. I had to buy the long burning stone in my hand. As for who to buy it for, there is no better fit for all of Nolan than Wayne.

When Wayne found that two long flint stones could be lit overnight, he hurriedly called Reynolds, and the core part of the hot air balloon, the fuel was solved.

After a day of urgent processing, the balloon's airbag was built.

Now Reynolds is using a series of tedious processes to raise the airbags.

Audrey, who is a good thing, will not let go of this opportunity, and pulls Yelena and runs over.

"Wood, you say this big bag made of coarse cloth can go up to the sky?"

Wayne just has nothing to say, can God change the adjective, it sounds so unlucky.

"If nothing else, it should be able to go to heaven. ”

"Hehe, if you can't fly, you've lost face in the whole Nolan. ”

"Go, Crow's Beak. Besides, failure is normal, scientific exploration is prone to failure, and this can be regarded as paving the way for the entire human race. ”

Audrey gave Wayne a blank look.

"Flim Flam. ”

Yelena couldn't stop sneering a few times when she saw this.

"Sister Elena, don't you say? ”

Elena whispered.

"What Master Wayne said is right. Even the young birds that have not grown up have to flutter a few times before they can reach the sky, let alone us humans who do not have wings. It's normal to fail the first time, just try a few more times. ”

Audrey curled her lips down and closed her eyes slightly.

"Sister Elena, you don't like me anymore, and you actually help that wood to speak. ”

Yelena had no choice but to let Audrey hold her arm and make a fuss.

Scholar Muhanxing is also looking forward to the flight of this airbag, as Rune's top intellectuals will look at the problem from the perspective of the entire human race. If it succeeds this time, it will be indelible for humanity as a whole.

"I hope I can succeed this time, otherwise it will really hurt the confidence of the researchers. ”

Wayne didn't care.

"If you don't succeed, you can silently be patient and not tight. Say, do you want to go up and have a look? The scenery is spectacular. ”

When Mu Hanxing thought about his body, it was difficult to ride in a carriage. I can't stand the toss.

"I thank Master Wayne for his kindness, but I can't stand the toss. I won't go up. ”

Audrey was a little angry when she saw that there was another person supporting Wayne. At first glance, it was an honest Muhammad.

Straighten your back and walk up to Muhanxing.

"What nonsense is the bearded man, if this big bag goes to the sky today, you will go up and explore the path for this princess to see if Ann is safe. ”

Muhan was sweating profusely when he heard this.

"Princess, this is really difficult for me. ”

Audrey finally let out a bad breath, and her mood was inexplicably better. Look at this beard, it's much better.

Unexpectedly, Wayne slapped Audrey's head with one big hand, and dragged Audrey's chin with the other. It shook up.

"You see that Mu Hanxing is honest, and he is a bully, right? ”

"Don't, this princess has finally put on a disguise, and her hair has been messed up by you. ”

Of course, in addition to Audrey, who doesn't want the hot air balloon to fly, there is also Merris, who is praying silently on the side.

"Lord forbid, don't let the devil fly like a brown bulb of tumors. May the Light purify everything..."

Today the square is bustling with activity.

Finally, with Reynolds' efforts, the airbag slowly left the inside and was erected.

Fortunately, there was a sandbag pressed against it, otherwise it flew away.

Reynolds shouted excitedly.

"Teacher, teacher, the hot air balloon is up. It's going to fly, it's going to fly!"

Wayne waved his hand and was ready to take off.

Reynolds herded the prepared pigs into the hanging basket, much to Reynolds' slight upset.

I even gave up the first chance to fly to a pig! I didn't want to go up myself, but I could give it to someone else. But what is a pig?

But the teacher said that for the sake of safety, he couldn't go to people for the first time, and Reynolds had to do that.

Reynolds threw the sandbags in the basket one by one, and the diagonal teams pulling the hot air balloon gradually struggled.

Under the command of Reynolds, the hot air balloon slowly ascended.

In the surprised eyes of everyone, the hot air balloon rose to a height of more than ten meters above the ground and hovered for more than ten minutes. When the fuel was almost burned, it was slowly pulled down.

Everyone was better for a while, and even Audrey couldn't help but cheer.

It's just that Merris's prayer is more urgent.

When it was finally time for the Venerable Master, Reynolds couldn't hold back his mood. Hurry down the fat pig. Can't wait to close the hanging basket, add long burning stones, and throw sandbags.

The strong man who commanded the rope slowly let go, seeing that his ground was getting farther and farther away from him.

Mu Hanxing couldn't help but admire.

A painter with a brush and paint ready to paint quickly on a blank piece of paper. Due to the strong influence of daylight, and the time is tight.

The painter can only draw a rough outline, and as for the details, he can only go back and fill in the imagination.

This day is two important days, one is the first time that humans touch the sky. The other is the birth of Impressionism in the art world (a way of painting outdoors, because the scenery is not static, and can only draw a rough outline quickly, thus producing a special hazy beauty).

As the altitude got higher and higher, Reynolds was already more than 20 meters above the ground. Reynolds took out the prepared binoculars and looked into the distance, the endless grasslands around Nolan, the busy workshops, the bustling citizens, and the birds hovering low in the sky.

The thought of being the first person to take to the skies made Reynolds feel so excited that he couldn't wait to see everything he saw.

Some citizens of Nolan noticed a large airbag in the sky and looked up.

"They all said that there was something in the square that could make people fly today, I thought it was the one-eyed lame man joking, but I didn't expect it to be true. ”

"Look, look, there's someone in that basket. ”

"Teacher, teacher, there's something flying, flying. ”

"This is what I usually tell you about thermal expansion and contraction, when the air in that air bag is heated, it expands, and then the density is lower than the surrounding air, so it floats up. ”

"Wow, I'm going to sit on it one day. ”

"Yes, when I grow up, I'm going to see what Nolan looks like from above. ”

I don't get angry when I see every child listening to themselves. Children at this age are playful, so how can they quietly stop and listen to those boring knowledge told by themselves.

However, this hot air balloon flight will still inspire many people to study physics and mathematics.
