April 18th. The weather was clear.
Li Longji held a small court meeting in Hanyuan Palace. Many people did not understand what was going on.
After the court meeting, Li Longji announced, "There is a new item called the hot air balloon. I have brought one today. The Winged Knights will demonstrate it to everyone."
Everyone was excited. They could actually see the legendary flying ball today.
Everyone waited. The Yulin Flying Cavalry led four horses here, and the horses carried the chest.
They used this to tell the officials that the hot air balloon was convenient to carry.
Then, the Winged Knights opened the boxes and took out something. They quickly assembled and tested it. The hot air balloon was inflated. Two people went up and controlled the alcohol burner.
The hot air balloon gradually rose under the gaze of the officials. When it was three hundred feet high, everyone in and out of the palace saw it.
The people on the road in front of the palace stopped to watch. They could see it clearly when they got closer.
There was a large basket under the colorful ball. The Winged Knights were in the basket.
The hot air balloon continued to rise. The hearts of the officials continued to sink.
They saw it clearly. It could indeed carry people, and it was the Winged Knights. What was the Emperor of the Tang dynasty trying to say?
When the hot air balloon used up the two hundred feet rope and moved with the wind in the sky, the cheers of the people reached Hanyuan Palace.
The officials whispered to each other.
"Good stuff. Take it out. Even if you don't use it, the other officials will send it back. They will be scared to death."
"It's best when attacking a city. It can choose the direction of the wind. If one side of the city wall is not used, the other two sides will deviate. Only one side can be used."
"If the wind is too strong, it won't work. If the rope suddenly breaks, the people on it will be blown away. If they fall, they will fall to their deaths."
"Who doesn't die in war? Falling to their deaths is a normal casualty."
"How long can the rope be? The longer the rope, the heavier it is. "
"How can there be a weapon without flaws? It's already good. With the hot air balloon, it will be helpful to the other soldiers."
"Exactly. Without the hot air balloon, are we not going to defend the city? Even if it can only reduce the pressure on one side of the city wall, the defenders on that side can go to reinforce the other walls. "
"It can also be used to see the enemy's layout from two hundred feet high."
"Yes, one can watch from above and the other can signal.
"If the soldiers at the border knew about this, they would be very happy."
"It's not expensive to make, right?"
"Even if it's expensive, we still have to build it."
The ministers expressed their opinions.
"Your Majesty, is it time-consuming to make this thing? Why don't we … "Yao Chong was the closest to Li Longji, so he asked about the time it would take to manufacture.
Without waiting for him to finish, Li Longji interrupted him, "There's no need. The Li Family Zhuangzi can build it. It won't take long."
"Faster than crafting a bow?" Yao Chong was still curious.
"A bow takes a long time, but a crossbow takes even longer. The cost of a hot air balloon is actually not as good as a crossbow."
Li Longji finally revealed the truth.
Crossbows required a lot of work and took a long time to complete. Hot air balloons were simple and had a shorter working time. Not counting the cost of the technology, they were naturally cheaper.
"Ah?" Yao Chong was surprised. He thought that a hot air balloon was not enough.
In the end, it was cheaper than a strong crossbow. It was normal for a strong crossbow to cost fifty to sixty taels.
"Then … Then …" Yao Chong did not know how to express himself.
"It's broken. The rope is broken. It broke about ten feet away." A shout suddenly sounded.
Everyone looked down. Sure enough, the rope floated down, and the other ropes flew away with the hot air balloon.
The ministers were anxious. Were two Winged Knights going to fall to their deaths today?
Li Longji frowned.
"Your Majesty, there was a sudden gust of wind just now, and the rope broke." Someone from the small yellow door ran over and explained.
Everyone who was watching the hot air balloon was stunned. The foreign envoys were excited.
It turned out that there was a disadvantage. Once the rope broke, people would fall to their deaths.
The ministers of Hanyuan Palace looked at Li Longji. Li Longji thought about it and ordered, "Serve tea and wait for the hot air balloon to fly back."
The ministers: "…"
If the rope broke and was blown away by the wind, how could it come back? Then what was the use of the rope? Did something happen to His Majesty because he was anxious?
At this moment, the two people on the hot air balloon encouraged each other.
"Old Six, don't be afraid. We said before that it can be changed. Quick, keep the rope. Let's think of a way to fly back. Don't fall into the wilderness."
An Non-commissioned Officer shouted.
"Got it, Big Lu. Quick, go higher. The wind direction is not right." Ol 'Six pulled the rope like a madman. His arms stretched out and retracted, tugging and pulling (the distance between his arms and his body).
He tied the rope into a bundle skillfully so that it would not be easy to untie.
Big Lu lit the fire and the hot air balloon rose quickly.
After rising to a certain height, the wind direction changed. However, it did not blow back. It continued to rise.
"It's a bit cold." Old Six was still there.
"The higher we go, the colder it will be. It's okay. Dongzhu said that after rising 333 feet, the temperature will drop by 6 degrees. We can persevere." Big Lu explained using science.
"If we had known, we would have worn cotton clothes. We won't be able to breathe no matter how high we go."
"Then let's go down. We can't be suffocated to death. At most, we'll fall into the wilderness."
"It's changed. Quick, this height. Let's go back. Aiya, it's not easy, but we can really do it."
"It'll be easy in the future. Bring the clothes in the basket. Bring Dongzhu's oxygen bag too."
After some manipulation, the hot air balloon was more than 3,000 meters in the air. It welcomed a new wind direction and blew back.
Fortunately, it was summer. The temperature dropped by 20 degrees. It was still bearable.
The two of them had discovered a new continent. Oh my god! They could look for the wind. Who said the hot air balloon could only fly in one direction?
This rope, what use do I have for it?
The two of them flew back. Li Longji was waiting.
Regardless of whether they flew back by themselves or sent a message back after landing, one of them would come back.
Li Longji did not believe that the Winged Knights would fall to their deaths. The hot air balloon was not going to be ignited. The altitude had to be lowered.
After waiting for about half an hour, a Gao Lishi who was looking around with binoculars suddenly shouted, "I see it. It's in the sky. It's very small. It's floating over. It's close, close. It's above our heads. Eh? It's over. "
Li Longji stood up and took the binoculars. Sure enough, he saw a small balloon flying in another direction.
Then the balloon started to descend. It flew to the left, then to the left, then to the right. After flying for a distance, it started to descend.
As the altitude decreased, people could see it without binoculars.
The hot air balloon that seemed to be getting smaller rose and fell. It seemed to be getting closer.
After waiting for another half an hour, the balloon became bigger. They could see the basket and the people inside.
The hot air balloon descended and was blown back by the wind.
The people cheered. The envoys were depressed. It could fly back and forth without a rope?
Li Longji smiled. Sure enough, the Winged Knights were the calmest. They were not afraid of unexpected situations.
The hot air balloon was flying toward Hanyuan Palace Hall.
The crowd excitedly waited for the balloon to land.
The people who saw it now were closer than when it was at its highest.
Many people's palms were sweating. It was probably because of the hot weather.
Closer, closer. Suddenly, a gust of wind blew. The hot air balloon floated away when it was about 60 to 70 feet above the ground.
The hot air balloon floated on the main road in front of the Imperial City. A shout came from above, "Tell His Majesty that we will be back soon. Aiya, this wind."
When the people below saw such a big thing flying over their heads and heard the shout, many of them said at the same time, "Oh ~ ~"
The hot air balloon quickly rose again and flew away.
"Wait a little longer." Li Longji said helplessly.
The officials: "…"
