"Okay, Your Majesty, you can hang this button on the rope next to it." When the hot air balloon was full of air, Yang Heng hung a safety rope on Li Erwei, and an iron button on the other end of the safety rope, which directly buckled on a rope of the hot air balloon. In this way, no matter how the hot air balloon bumps, it will not fall even after it is pushed out.

Someone may ask, why not prepare a parachute? Yang Heng took Li Er to the sky and just let him take a height of five or six meters, and it will never rise again. When raising, you need to let go of the rope pulled below. It is better not to let Li Er do dangerous things, so the parachute is useless at this height.

"You guys, pull the rope and slowly let it take it air, but don't let it go too quickly." When Yang Heng took the air for the first time, he didn't let someone pull the rope. He just stood firm in the wooden box and let the balloon rise naturally. But now Li Er is on it, and he dare not let Li Er be frightened. Even Li Er's guards stood nervously below. Once something happened, they would come as a meat pad as soon as possible.

"Is this no different from standing on a bell tower?" Yes, there is no difference, it's just a little shaking. This height is really the same as the bell tower.

"Can you let go of the rope after learning literature? We climb higher?" "No, Your Majesty, this is not true. You are the lord of the world. If something happens to Your Majesty, I can't afford it."

"Haha, will you let me get something wrong?" Li Er kicked the ball to Yang Heng again, "Of course I won't let Your Majesty get something wrong." "That's all. Keep going up." "Okay, Your Majesty. Let's go down and prepare first, you guys, pull the balloon down, hurry up, be more stable."

"Yang Heng, what crime should you do? You actually bewitch Your Majesty and take risks with you. Your Majesty. Think twice. You must know that the Tang Dynasty needs Your Majesty." You know that this would happen. As soon as Li Er came out of the box of the hot air balloon, a minister rushed over and even directly accused Yang Heng. At this time, Yang Heng would definitely not interrupt.

"Your Majesty, the saint has said that a gentleman will not stand on a dangerous wall, and as a king, your Majesty, who is the common ruler of the world, should not appear in a dangerous place."

Looking at what was happening in front of him, Yang Heng felt very interesting. Yang Heng could naturally ensure safety in this hot air balloon. Even if he encountered strong convection at a high altitude, Yang Heng was not worried about anything. However, these ministers did not understand this matter well. People had to go to the sky, and there was an unknown thing sitting.

However, in the end, Li Er won, and the ministers agreed to Li Er's idea of ​​going to heaven.

"Yang Heng, I tell you that you must ensure the safety of Your Majesty, otherwise there will be no need for your Yang family to exist." This, for the sake of Li Er's safety, Yang Heng would not be angry. Yes, even if he relies on Li Er to live so comfortably, he naturally would not let Li Er have any danger.

"Your Majesty, you carry this thing on your body, and this safety rope, and this end is hung on my waist." This time, Yang Heng took out a parachute and carried it for Li Er to carry it, and even carried one by himself. Because Li Er had not been trained, if there was a danger, he had to open the umbrella for Li Er first, then leave Li Er, and then open the umbrella by himself.

"You all follow the back of this hot air balloon. If something happens, you must catch His Majesty as soon as possible. You four are waiting here. Once we throw the rope down, you immediately tie the rope to the stake in order. Then listen to my orders without orders. Don't run around."

After Yang Heng gave a round, he followed Li Er into the wooden box and closed the box door. The box was more than half a person tall. The circle of ropes around him were tied firmly with the rope pulling the box. In fact, no matter how bumped the box, the person inside would not be pushed out. In front, Yang Heng was purely a psychological problem, so he fixed Li Er to the rope with a safety belt, but this time he did not fix this thing. If it was fixed to the rope, if it was really dangerous, it would be difficult to untie it, and it might be even more dangerous for people.

"Your Majesty, give it, you can take this. After the balloon is launched, your Majesty can take a good look at the scenery of Chang'an." Yang Heng gave Li Er a telescope, which was also a way to relieve Li Er's nervousness. It would be fake to say that Li Er is not nervous, but the temptation of taking off is too great.

As a noise sounded, the steam engine started, and Yang Heng also shouted loudly above, "Unlock the rope and let go." So there were eight people below, one was pulling the rope and the other was untiing the rope. In this way, four groups of people worked together to untied the rope, then shouted one, two, and three, and at the same time released the rope in their hands. As the rope was released, the hot air balloon swayed and rose up to the sky, while Yang Heng was controlling the balloon to start flying out of the city. At this time, the hot air balloon was not flying very high, and Yang Heng did not throw down some counterweight sandbags inside. Why were they afraid of hitting the people below? Because of Li Er's request, Zia's takeoff in the city was so lively, and there were many idle people following below, cheering and praying.

"This is to the city gate, learn literature, and be at a higher level, I'm going to see the whole picture of Chang'an City." "Haha, Your Majesty, don't worry, I'll let the balloon fly high when I go outside the city. If it doesn't work now, there are too many people below, so it's not good to hurt people."

Yang Heng didn't care about looking away, but passed a small hole and paid attention to the bottom. His observation hole was directly below the balloon, which was set to adjust the position of the balloon.

"Okay, Your Majesty, the rope on your right hand side, I'll shout one or two, let's pull together, one or two, pull." These are some sandbag counterweights on the side. They were originally pulled by Yang Heng himself and needed to be pulled in balance. Once the rope was pulled open, the two sandbags would fall down. In this way, pairs of sandbags fell down, and Yang Heng also stabilized the balloon. Although it was not too stable, the fan driven by the steam engine had already fought against the wind in the air, allowing the balloon to hang in the air, and the balloon was rising steadily.

"Your Majesty, how are you doing now?" "Haha, it's great, it's great, I can see the whole picture of Chang'an City, and even the scenes in the distance. This is really a small view of all the mountains." Whose poem was actually told to Li Er to tell him in advance.

"Your Majesty, let's go back, otherwise the officials below will have to worry. I am worried about my great head." "Okay, go back," Li Er said unsatisfiedly. Originally, he wanted Yang Heng to push the balloon to run at high speed for a while, but when he saw the ministers below who had changed their faces, he changed his mind. If he went freely, the court would probably be very uneasy in the next few days, and Yang Heng would even become a public enemy in the court.

When Yang Heng heard the word "return", he felt relieved. Otherwise, if Li Er continued to let him fly for a while, he really didn't know what to do.

Yang Heng adjusted the direction of the power with one hand and the size of the flame with the other hand, so that the balloon could descend and look for the landmark to head towards the city. Slowly, the balloon came to the sky above his home. Although the positioning of the balloon was not so accurate, it was already above the yard.

"Please pay attention to the ropes below. Once they are attained, tie them up as soon as possible." When Yang Heng found that the person below had already pulled the ropes, he also stopped the steam engine, and even the stove that provided the heat was locked up.

"Your Majesty, there's nothing wrong with me. I'm not allowed to go up here again, otherwise I'll be willing to give you a desperate advice." Yang Heng suddenly realized that the ministers below were much ugly than Li Er's. They were really nervous.

"Hehe, boy, just wait for the anger of the ministers." Well, Li Er has all come down safely. It is really unreasonable that these ministers want to threaten him.
