"take off!"

With the emperor's order, the people on the hot air balloon opened the ropes on the iron chains that tied the hot air balloon. As the ropes were thrown down, the hot air balloon began to shake.

When the last rope was dropped, the hot air balloon began to float towards the sky, with a slow speed, but it began to fly upwards little by little by little to the naked eye.

"This really flew up!"

The emperor said to himself that since the prince said that he had traveled with the gods in the fairy world, he had been looking forward to the fairy world and wanted to go up and take a look. Now the emperor even wanted to replace the people in the bamboo basket and go up by himself, but knew that this was impossible, so he could only watch the hot air balloons flying towards the sky.

"Zhuge Lantern was invented for nearly a thousand years. Why did no one think about making a big Zhuge Lantern to bring people to fly, the first flying man in the world, what a great honor..."

The emperor said to himself and looked at the prince beside him. It seemed that the prince had changed a lot this year, and the changes in the entire Yutang Empire were also because of the prince. The emperor must have dared not easily imagine that people could fly into the air like gods.

"Father, it's just a matter of knowledge. My son has seen these things in the fairy world, broadened his horizons and provided students with ideas, and thus made these inventions!"

Yu Zhiqian said slowly, the ancients were not stupider than modern people. He even said that many times the ancients were smarter than modern people. He used the later modern people, which had been in nearly a century of breakthrough in physics, and was using the wisdom of Einstein's generation.

Although Yu Zhiqian didn’t know this and that, Yu Zhiqian pushed open a window, allowing students of this era to see a new world. Once the inspiration is opened, various inventions will emerge like mushrooms after a rain.

"Well, your students are good!"

The emperor spoke softly again, Yu Zhiqian looked at his father with eyes, waiting for his father's next sentence, the research funds he had applied for were approved, 300,000 taels were not a lot, maybe with this money, the emperor could realize his dream of flying.

But the emperor pretended not to see it and continued to stare at the hot air balloons flying higher and higher.

On the hot air balloon, Zhang San and Li Si looked at the people getting smaller and smaller below, and looked at each other: "Are we ascending?"

These two people are chores of the academy. This more dangerous flying mission will definitely not allow students to come in person, but to find these chores. Of course, they will be rewarded regardless of whether they succeed or not. For example, this time, Zhang San and Li Si can get a reward of fifty taels per person.

"I don't know, what do you think those people over there are doing?" After saying that, he pointed to a corner of Chang'an City.

Although the gunpowder explosion was heard in Chang'an City, it did not affect the lives of the people. For the people, such plain thunders will appear once or twice in summer, so the people don't feel much. When the glider experimented, the people did not see it because of the distance and the target was small.

This hot air balloon is different. The hot air balloon flew to the sky for the first time, and people in Chang'an City could see the hot air balloon flying in the sky.

"There are gods in the sky!"

This was the first reaction of ordinary people. Some people knelt on the ground and started kowtowing. One by one, ten, ten, and ten, and soon almost everyone in Chang'an City ran from the street to the street to watch the hot air balloons in the sky.

"Your Majesty, you should issue an order to appease the people quickly, so as not to cause unnecessary panic!"

Di Renjie looked at the hot air balloons in the sky and was the first to reflect it. He saw the hot air balloons take off with his own eyes and felt very shocked, let alone ordinary people. Di Renjie could imagine what ordinary people would behave after seeing the hot air balloons.

"It's still the thought of Di Xiang. Come and pass the order so that the people don't have to panic. This is a newly invented object!"

"Here!"

Soon an eunuch ran out of Tsinghua Park and began to impose an order.

In Chang'an City, the hot air balloon began to enter the area above the East City. Now we can only see the shape clearly. Many people are following the hot air balloon and want to see what is flying in the sky.

"Immortal, Immortal, take me away!"

"The gods appeared..."

Dongcheng became chaotic, but soon a team of cavalry appeared and shouted: "Don't panic, this is not a god, this is the newly invented flying artifact of our dynasty, called a hot air balloon, and it is undergoing a flight experiment. Let's disperse!"

The cavalry shouted and continued to move forward and passed the message out. After hearing the news, many people got up from the ground, patted the soil on their bodies, looked at each other, and then smiled awkwardly.

"Is this my newly invented flying artifact?"

"It seems that what the sergeant said just now. My dynasty can already fly to the sky?"

"Fuss, we are the country of the Heavenly Kingdom. What's so great about flying in the sky? I've known that some of us can fly and escape. Do you know the old immortal in Huashan? I heard that the old immortal can fly directly without these external forces!"

"Really, fake, can I still lie to you!"

A soldier specifically explained the hot air balloons in the sky. Chang'an City has returned to peace, but the people are still discussing the hot air balloons in the sky. In their words, they can hear pride. Especially in the western city, the people who had originally looked down on the Hu people, but now they look down on them even more, just look at the Hu people not far away with their noses.

I heard that you Hu people are very good at fighting? Sorry, you can't beat us, we can still fly in the sky now! The Hu people also saw the hot air balloons in the sky, and their attitude became more respectful, fearing that they would anger the Han people beside them.

After flying around, the hot air balloon finally flew towards Tsinghua Park and slowly lowered its height. This time, it still flew over the people in Chang'an City. However, this time the people were not kneeling down, but pointed at the hot air balloon and discussed how the hot air balloon flew. Some people even had better eyes and could see the people sitting on the hot air balloon.

In the end, the hot air balloon fell back to Tsinghua Park without any danger, but fell into Weiyang Lake. There was no way. The current technology had not yet reached the point where it could be accurately landed, so it finally landed in the lake. Soon, it rushed over with the guards with good water properties to salvage Zhang San and Li Si and others from the lake.

The other students in Tsinghua Park were rowing boats and began to pack up hot air balloons. They had rich recycling experience and often all kinds of things fell into the lake, and they were able to accurately find the things.

"The Caomin has seen Your Majesty!"

After the two were caught, they were taken to the emperor. The emperor looked at them with a smile: "What is in heaven?"

"In the sky?"

The two of them thought for a moment: "When you go back to your highness, there is nothing, and it is not much different from what you see on the ground!"

After hearing this, the emperor frowned and looked at Yu Zhigan. Yu Zhi smiled dryly: "Father, there is really nothing in the sky. The clouds we see are a bit like water vapor, which is the fog that appears after we boil water. This is roughly the clouds in the sky, and it is the same as the ones going up!"

"Where did the gods you saw take you to?"

The emperor was a little disappointed, thinking that he could go to the fairy world to take a look after it, but the result made him very disappointed.

"Father, this is a bit troublesome to explain. How can I describe it? That is to say, the immortal world is not in the same space or in the same dimension as us, and only the gods can take us through time!"

"Where is that god!"

The ears of the people around him were erect. Not only the emperor cared about the gods and immortals, but now everyone cared about the gods and listened with their ears, hoping to get some news about the gods and immortals from Yu Zhigan's mouth.

"The Father and God are not on the planet where we live. If we want to find Gods, we still have a long way to go, at least we must fly out of the earth!"

The emperor also heard Yu Zhigan say the so-called theory that the earth is a ball. When he heard Yu Zhigan's words, he shook his head in disappointment and looked at Zhang San and Li Si: "Reward a hundred golds!"

After saying that, I saw that part of the hot air balloon had been salvaged, so I walked over quickly and looked at the hot air balloon: "When can I take this hot air balloon to the sky and take a look?"

When Lu Su saw the emperor, he thought for a moment: "Your Majesty, there is a certain danger in flying this hot air balloon, Your Majesty..."

The emperor frowned again and looked at Yu Zhigan. Yu Zhi smiled dryly: "Father, this hot air balloon is not safe yet. After you research the inert gas in the future, you can fly. You don't have to worry!"

"Um!"

After the emperor finished speaking, he waved his hand: "This Tsinghua Park is doing well, go to the Whampoa Military Academy to take a look!" After that, he took the lead and walked out. Yu Zhigan immediately followed behind him, constantly thinking in his mind how to remind his father of the matter of asking for money, which cannot be delayed.

"Father, what do you think of these research results today?"

"Eye-opening! Especially gunpowder and hot air balloons!"

The emperor walked and thought about it, then slowly spoke, "How much weight can the hot air balloon bear?"

"We can bring five adults for the time being. The specific number has not been tested yet, but depending on the size of the sphere, the weight can be carried differently!"

"If the hot air balloon and gunpowder are combined!" The emperor's words lit up the eyes of the generals around him. Yes, why didn't you expect it? However, Cheng Chumo's glider seemed to have no effect in this way.

"What the father said is that the sons were negligent!"

Yu Zhigan did not expect this, mainly because he did not expect that the Yu Tang Empire would have an air force so soon. However, it was a bit early to establish the air force, and the hot air balloons were still a bit unstable.

"Well, hurry up and make hot air balloons and gunpowder jars, I'm very useful!"

As soon as the emperor finished speaking, Cheng Yaojin immediately became excited. The emperor said that it would be of great use and he must be preparing to conquer Goguryeo. Fighting Goguryeo is not a small country. It is impossible to only mobilize those young generals. The older generation also had to mobilize. Cheng Yaojin's bones were a little sore in Chang'an City. Finally, he could fight well!

"Father, this, this..."

Yu Zhi looked at his father in a scrupulous manner, thinking that he could make hot air balloons or something, but he had to pay. The emperor never mentioned money until now, so Yu Zhi was a little anxious, after all, he couldn't do anything without money.

"What? Is it difficult?"

Yu Zhigan immediately nodded like a chicken pecking at the rice: "Yes, Father, Father, I don't know anything. The hot air balloon and gunpowder pot are all made, and they all require money, but Tsinghua Park is no longer rich. The last time I asked you for money, you said that I'll talk about it after seeing it. You can see this money..."

This time, the emperor looked at Yu Zhigan as if he had a sudden realization and patted his head: "This is my negligence. I forgot about this matter, Fan Jian!"

"I'm here!"

"The Ministry of Revenue allocates 200,000 taels of silver to the prince!"

Fan Jian nodded and wrote down the matter, but Yu Zhigan shook his head: "Father, it's 30,000 taels!"

The emperor looked at Yu Zhigan with dissatisfaction. Yu Zhigan could only shrink his head back. Two hundred thousand taels were about 200,000 taels. With this money, it all alleviated the urgent need. After all, you can't use your own money to subsidize it. But soon Yu Zhi turned his eyes and looked at Cheng Yaojin.

"Shangshu Cheng!"

Cheng Yaojin is a Duke of the Kingdom and is also one of the Ministers of the Ministry of War. The Ministry of War is different from other departments. There are many Ministers, and Cheng Yaojin is one of them.

"Your Highness the Crown Prince!"

Cheng Yaojin was in a good mood today and had a smile on his face all the way. Although this guy smiled even worse than not, at least he didn't have to worry about this guy slap him down. Yu Zhi fucked this little body, but he couldn't stand this guy.

"Shangshu Cheng, His Majesty said that the Ministry of War would purchase some gunpowder jars and hot air balloons. These things are expensive and need to discuss with Shangshu Cheng!"

After hearing this, the emperor turned his head to look at Yu Zhigan: "This Ministry of War needs hot air balloons and gunpowder jars and still needs money? Didn't I give you 200,000 taels just now?"

"Father, you just allocated research funds, which means that the cost of studying these hot air balloons and gunpowder tanks is required. The subsequent improvement of hot air balloons and gunpowder requires this money. At the same time, the remaining research in the academy also requires the use of this money, but the procurement costs of the Ministry of War need to be calculated separately and cannot be confused!"

Yu Zhigan began to explain the so-called procurement to the emperor again. Although the court often went to purchase some things, it was the first time to purchase things from the place where he allocated money.

The emperor had only a little understanding of why the Ministry of War had to pay the money, but in the end he accepted Yu Zhigan's proposal.

Yu Zhi's eyes began to turn again. What should the price of hot air balloons and gunpowder jars be sold? After all, it is cheap and does not meet the identity of these things.
