Fei Weisan's hot air balloon experiment progressed the most smoothly. After all, there was the Kongming lantern that had been passed down for thousands of years and the drawings drawn by thousands of troops. The principle of the entire hot air balloon is also very simple.

After the fifth experiment was successful, Wang Lihui couldn't wait to board the hot air balloon and experience the wonderful experience of flying into the sky.

Wang Lihui looked down at a height of hundreds of meters and saw that the Yangtze River had become a green belt, and the world was empty, just like what the people who climbed the hot air balloon said a few times ago, and he was grateful in his heart.

After Fei Weisan's hot air balloon experiment was successful, he was the first person to climb into the sky. However, after climbing into the sky, he thought he would see the heaven, and he could see the bottom of the heaven, but the sky was vast and there was nothing.

The third experiment was the craziest. In order to find the bottom of the heaven, Fei Weisan flew the hot air balloon alone to a height of 1,000 meters. In the end, the fuel was insufficient and he had to fall back to the ground.

Then, Fei Weisan fell into deep thought. If there was no floor of the sky at high altitude, why would the rocket launcher always fall back to the ground after flying towards the sky?

Later, Fei Weisan came up with more questions from this and that, why did the hot air balloons fly several thousand meters high and eventually fall back to the ground?

Fei Weisan suddenly discovered that many things that he used to be used to are now in his mind, and why the stones fell to the ground when thrown out, and why the person fell to the ground when he fell.

Since Fei Weisan discussed this issue with everyone many times, Wang Lihui felt that Fei Weisan was crazy. It must have been the experiment that climbed high altitude that angered the gods.

The institute then no longer asked Fei Weisan to be responsible. After the fourth hot air balloon experiment, Wang Lihui started. In order to ensure safety, Wang Lihui limited the height of the hot air balloon to a range of 200 feet.

After Wanjun arrived in Hanyang, he left Wang Huan to rest in the government office, and ran to the Academy of Sciences without even having to rest.

When Wang Lihui learned that Wan Jun was coming, he started the sixth experiment in advance, so that Wan Jun could feel the feeling of climbing the air and ask for some help.

The huge hot air balloon is attached to the ground and slowly floats up under the influence of hot air, occupying most of the institutes in the Academy of Sciences.

Wang Lihui smiled at Wan Jun, "The Head of State has a rare trip. The hot air balloon you mentioned has been successfully tested. Please climb the hot air balloon and feel it."

Wan Jun raised his eyes and looked at it, climbed into the wooden frame. Wang Lihui and an operator followed, and then Wang Lihui shouted, "Put on the air!"

Wan Jun held the wooden frame, and Wang Lihui smiled and said to Wan Jun, "Head of the People's Republic of China!"

Sure enough, as the hot air continued to pour into the hot air balloon, the wooden frame trembled gently and slowly left the ground.

After passing everyone and flying over the house, the hot air balloon flew higher and higher. Wan Jun looked at the scene in front of him and suddenly seemed to have returned to that world. At that time, Wan Jun was a lieutenant of the Aerospace Army. Under the thrust of the rocket, he left the ground and entered space.

The hot air balloon floated slowly and hovered in the air of 400 meters.

Wan Jun came back to his senses from his memories, "Can you only fly so high?"

Wan Jun's calm reaction made Wang Lihui a little unexpected. Everyone, including himself, was extremely surprised and excited when they first took off, but Wan Jun seemed to be used to it.

Wang Lihui said, "You can fly higher, but it is not very safe."

Wan Jun said, "Higher!"

The hot air balloon climbed up again, but soon stopped again, Wan Jun said, "Is this the highest?"

Wang Lihui said, "I dare not be taller, if I grow taller, something will happen."

Wan Junqi

He said, "Is something wrong?"

Wang Lihui hesitated, "It's something wrong. Flying too high will anger the gods, and Fei Weisan will go crazy."

Wan Jun heard of this for the first time. After asking, Wang Lihui told Wan Jun about Fei Weisan's third experiment and Fei Weisan's abnormal behavior afterwards.

After saying that, Wang Lihui said, "Your Majesty, what a pity."

Wan Jun smiled and looked out from all directions. The earth was like a chess board, and the rivers and houses were scattered on the chess board. If two armies were fighting, there was a hot air balloon to observe from a high altitude, all the arrangements of the place would become one-way transparent.

Wan Jun said, "Okay, go back!"

The hot air balloon slowly landed on the ground, Wan Jun walked down the wooden frame and smiled, "Not bad, go and call Fei Weisan to see me."

Everyone in the institute looked at each other in front of Wang Lihui, and whispered, "Fei Weisan is crazy."

Wan Jun said, "Just go and call me."

Soon someone took the guard away and went to bring Fei Weisan over.

Fei Weisan looked haggard. When she saw Wan Jun kneeling on the ground excitedly, she shouted, "Head of War! I'm not crazy!"

Wan Jun pushed away Wang Lihui and the guards who were blocking their faces, walked up to help Fei Weisan up, "I know you're not crazy."

Fei Weisan looked at Wan Jun incrediblely, not knowing what to say for a moment.

Wan Jun said, "They all said you were crazy?"

Fei Weisan nodded and suddenly turned red in her eyes, "They all said I was crazy, and it was useless to explain it!"

Wan Jun said, "Just tell me, what did you think of?"

Fei Weisan said, "I climbed a thousand meters high, and there was nothing there. There was no difference between clouds and morning mist. I could not see the gods and the heavens."

After saying that, Fei Weisan looked at Wan Jun, and Wan Jun smiled and said, "It's okay, you said yours."

Fei Weisan said, "If there was no Heavenly Court blocking it, why would the rocket launcher fly so high and fall down? Then I felt that many things were abnormal."

Wan Jun said, "How is it wrong?"

Fei Weisan said, "Why does the rain fall on the ground? Why does the thrown stone fall on the ground? People will also fall on the ground when they jump."

Wang Lihui said, "Be careful, the head of state, look at him being crazy again, rain and snow fall, people jump up and land. Isn't this the world like this? What a normal thing."

Wan Jun looked at Wang Lihui and said, "Since it's normal, then tell me, why does the rain fall on the ground and why doesn't he fall into the sky?"

Wang Lihui looked at Wan Jun in surprise and said, "Head of the People's Republic of China, why do you say these words like Fei Weisan?"

Wan Jun said, "This is not crazy, it is called studying things to gain knowledge. Since it is about research, you must have the spirit of breaking the casserole to ask the end. The more you are used to things, the more you hide the principles you don't know."

Fei Weisan knelt on the ground and cried, "Thank you, the Head of State."

Wan Jun reached out and grabbed Fei Weisan and said, "You are very good. You should know that the person who was hit by an apple in history is still a toddler. Now you are the first person to be hit by an apple."

Fei Weisan said, "Head of the People's Republic of China, I have never been smashed by an apple."

Wan Jun said, "I'm just giving an example. Why does a ripe apple fall on the ground, and why doesn't the moon in the sky fall on the ground?"

Fei Weisan said, "I haven't figured it out yet."

Wan Jun really wanted to pat his head and tell him what gravity is, but think about it, since this timeline has reached this point, why not let them explore and discover it on their own?

Wan Jun said, "You can be good at the research institute

Think about it, do experiments, it can take three or five years, and then tell me if you think it clearly.”

Fei Weisan said excitedly, "Head of the People's Republic of China, you are really my new parent."

Wan Jun said, "You go and wash and clean up. If you have any new discoveries, you can also write to me."

Fei Weisan bowed and left in tears. Wan Jun didn't expect that in this era, someone would explore the gravity of the world. When he remembered the steam engine, he asked, "How is the steam engine I want?"

Gong Bisheng, the one who studied the steam engine, was waiting aside for a long time, and then he heard this and walked forward, "Go back to the head of state, the steam engine is progressing very smoothly."

Wan Jun said, "Lead the way, let's go and have a look."

In a room away from the yard, the steam engine was a half-person-high iron lump with various pipes connected to it, but it can be seen that the steam was spitting out at the connection of the pipes.

A transmission rod is connected to the crankshaft, the curved arm drives a gear, the gear is connected to a wheel fan, and the fan blades are constantly rotating, blowing cold wind towards everyone.

Wan Jun said happily, "Have you reached this level?"

Gong Bisheng hurriedly said, "But it's a bit of a weakness. The iron material cannot keep up. If the things in the curved arm belt are too heavy, it will easily explode the pipe."

Wan Jun said, "I'll ask someone to do the iron material, so you can continue to study it and let this thing be put into use as soon as possible."

In the research institute, Wan Jun stopped a few too ridiculous research, and then in the office building of the institute, Wan Jun said to Cui Ziyi, "Other than the steam engine and gravity, your people are all bullshit!"

Wang Lihui said, "What are the gravity, head of state?"

Wan Jun stopped his impatient mood and said, "Except Gong Bisheng and Fei Weisan in your research institute, the rest of them are wasting money. Those who study black dog blood and donkey hoofs will drive them away."

Wang Lihui nodded repeatedly, and Wan Jun thought for a while and said, "You can't blame you for this. Research is aimless to find a way, so you will inevitably take some detours."

Wan Jun said, "You go and pick some people for me, be smarter, loyal and reliable. What I want to do is important and must be absolutely confidential."

Wang Lihui nodded and retreated. After a while, he led a few people in.

Wan Jun said, "There was someone named Wang Amao in the research institute before. Do you know this?"

Everyone was stunned for a moment, nodded hesitantly, and Wan Jun said, "It's good to know. I want you to keep it absolutely confidential. Once there is any news, I will end up like Wang Amao. If you are willing, sign a life-and-death case. If you don't want it, I won't force you. You can go back and continue what you have done."

Several people looked at each other and stood there. Wan Jun smiled and said, "Very good, you will all be heroes of the empire!"

Wanjun asked the guards to guard the house, and no one should approach within 30 meters. After everything was ready, Wanjun said, "Each of you will receive a 200 taels of family settlement fee. There will be a dedicated person to send it to your relatives according to your requirements. You can write letters to your relatives, but you must also go through inspection. Do you understand?"

Several people said, "I understand!"

Wan Jun said, "Lihui, you are responsible for the confidentiality agreement, and you must explain it to everyone!"

Wang Lihui nodded. What he was even more curious about now was what was so mysterious and mysterious.

Wan Jun said, "By the way, I remembered it. I seemed to have talked to Gong Bisheng last time, so I would also count him."

After saying that, Wan Jun picked up his pen and drew circles on the paper. A square object was built with a long tube in front and a strip object with long wings stretched out on both sides.
