The earth has 365 days a year, and this world has 30 days a month, and there are only 360 days in a year.

"On February 30, 72 years of the Great Yao Calendar, the world's first hot air balloon is about to take the Hulk full of anger to the sky. A deep voice rang out from the sidelines.

"My lord, what is the Hulk?" the official who was recording looked up with a question mark.

"You don't care what it is, just write what I say. ”

In addition to the angry Hulk, this balloon also carries the dream of human beings who have wanted to fly into the sky for thousands of years, and it also opened the beginning of human exploration of the sky. Ren Baqian continued.

"What the hell is the Hulk?" asked the empress this time as she leaned behind Ren Baqian.

"Hulk represents power!" Ren Yachidao. It's a metaphor. ”

The empress glanced at Ren Baqian suspiciously, she always felt that he was lying again.

"Say, how much of what you said to me back then was true and how much was false?" the empress asked suddenly.

"With Your Majesty's wisdom and skill, can you hide your Majesty's lies?" Ren Baqian said with a smile.

The empress snorted lightly, and then lifted the sudden thought.

At this time, the position of everyone is the square in front of the palace.

In addition to the empress, there are also ministers of the court, students of Zizhu Academy, and many children of officials' families watching the excitement from a distance.

In the middle of the field is a hot air balloon being prepared.

There was no thermal control, no protective equipment, just a hot air balloon and a bamboo basket underneath, and a large stove above the basket.

As the coal and firewood in the furnace burned, the hot air balloon gradually inflated and began to lift off the ground with the bamboo basket underneath.

"One world, one dream......" Tu Wan read word by word as he looked at the font that was fully revealed as the balloon inflated.

Immediately, someone ran to the side to see what was written in the other directions.

"If the heart is in a dream, it will be in ......"

"I'm going to fly into the sky and stand shoulder to shoulder with the sun...... These words have momentum and are deeply understood by the old man. Qin Chuan laughed.

Although some time ago, Ren Baqian and the empress jointly suppressed it with volume and force, but these people didn't have much grudge.

Most of the ancient people are straight! Unless they are ruthlessly offended, for example, Ren Baqian offended that harrier ruthlessly in the first place, and ordinary small disputes are not in their eyes.

"Can this thing fly?" Qin Chuan asked as he leaned over to Ren Baqian's side.

"Naturally, you can see it soon. ”

"If this thing can fly, then can it bring soldiers into the enemy city?" Qin Chuan asked.

"Then someone shot down with an arrow, and they all fell down and died......" It was useless for Ren Baqian to open his mouth, and Tong Zhenye said it, and by the way, he looked at Qin Chuan with a mocking expression.

"It's all quiet!" the empress said coldly.

Both of them immediately stopped the words in their mouths, glared at each other, and then stood on either side.

"Senior, it's almost ready. Remember, if it falls, be sure to open the cloth as soon as possible to increase the resistance and slow down the speed. Ren Baqian stepped forward and patted Li Fudao.

Actually, you don't need to use ifs, you should use affirmations.

"You know, this thing can't go all the way to the sky as you said, but it's good to be close to the sky, and I'm going to see it with my own eyes. Li Fu was not as crazy as a few days ago at this time, and he completely calmed down.

"Well, the materials are not up to par yet, and we can make better ones in the future. Ren Baqian nodded.

However, Ren Baqian knew in his heart that even if he made a modern level of hot air balloons, it was useless, the rise of hot air balloons completely depended on the buoyancy of the air, and after reaching a certain height, the air was thin, and even the high technology could not make the hot air balloon reach the level of a rocket.

"That's okay, the old man will go up and have a look first!" Li Fu said as he stared at the hot air balloon and began to float up little by little.

"Use the coal first, and then use the molten wood when you reach a certain height, because the molten wood has a bigger flame and allows you to fly higher. Ren Baqian repeated the reminder again.

"Yes. Okay, the old man is going up. Li Fu waved his hand, and then jumped into the bamboo basket on the hot air balloon.

As Li Fu pulled the rope on the hot air balloon, the hot air balloon began to slowly take off.

Immediately there was a burst of exclamations around the field.

Being able to fly is a huge surprise for most people.

However, the students of Zizhu Academy are all proud, and they all know the principle and production method of this thing. Looking at the shocked expressions of the others made their hearts extremely happy.

Many craftsmen of the Zhang family also watched this scene dumbfounded, completely unaware of how this was done.

As the hot air balloon flies higher and higher, you can see this flying behemoth all over the city.

"Look, there's something flying!" someone shouted pointing to the sky.

In just a few moments, a group of people stood beside him, looking up at the sky one by one.

"What's that?

"It's still written on it!"

"What is written?"

"I'm going to fly into the sky and stand shoulder to shoulder with the sun!" said someone with good eyesight, word by word.

"This thing is going to fly to the sun!" everyone suddenly let out a burst of exclamations when they heard this.

Soon, the hot air balloon flew higher and higher in everyone's eyes, until it became a small dot, and then a strong wind blew......

The hot air balloon was blown away in full view......

Everyone looked at the hot air balloon that quickly disappeared in the sky, and looked at Ren Baqian in unison.

"The sky, like the sea, is an area rarely set foot by humans, full of opportunities and dangers!" Ren Baqian touched his chin and said with a deep expression.

"Will he ever come back?"

"The fuel is only enough to burn for less than an hour, so it shouldn't fly too far, right?" Ren Baqian said as he put his hand above his head to block the sunlight and looked into the distance.

"Your Majesty, let's go back. Ren Baqian turned to the empress and said.

Then the two returned to the palace, and the others dispersed. It is time to go back to deal with official business, it is time to go back to make clocks and watches, and it is time to go back to make locomotives.

However, for the children of those officials and ordinary people, such a big thing flying into the sky is still something that they can discuss for a long time.

No matter what world you live in, people are extremely enthusiastic about the dream of flying in the air.

"I heard that something flew into the sky in front of the palace today?" Qinglian was asked by Ning Caichen as soon as she returned home.

"Yes!" Qinglian nodded.

By now, she thinks it's awesome and funny. If she had the chance, she would like to sit on that thing and go up to the sky to see what it looks like.

"What's that? How?"

"I did see how it was called a hot air balloon, but it was a bit troublesome to get the materials together. Qinglian said.

"If only I could go up to heaven and see it. Ning Caichen said with some yearning.

"I heard that thing is going to fly to the sun, the sun is so hot, will it catch fire?" Ning Caichen asked again.

"Uh......" Qinglian was stunned, she really hadn't thought about this question.

There are many such discussions in the city.

This hot air balloon does not have much technical content in Ren Baqian's eyes, but it makes many people feel very powerful.

Being able to take people into the sky is simply amazing!

The reputation of Zizhu Academy also took this opportunity to greatly promote it in Lancheng.

In the next few days, the most lively topic discussed in Arashiki was whether flying into the sun would catch fire......
