Chapter 338

Hot air balloons are still floating over Qingzhou.

Lin Wentao and others are chasing after each other. Just when they are tired and panting, suddenly the sound of horse's hooves comes.

"Come up." Xiao Ming rode to Lin Wentao.

Lin Wentao was stunned, and suddenly he was at a loss.

"What are you doing? If the balloon disappears, I won't give you another one." Xiao Ming stares at him and says.

Lin Wentao immediately became impatient and climbed onto Zhao Long's horse.

Looking at the balloon, Xiao Ming and Lin Wentao chase out, followed by Zhao long and Zhao Hu.

The balloon kept flying westward, and the rope under the balloon fell down. Xiao Ming was glad that Lin Wentao had made the rope longer this time.

Maybe this guy flew the balloon like a kite.

Following the balloon, people soon chased out of the city, and the balloon flew lower and lower outside Qingzhou City.

Immediately Lin Wentao and Xiao Ming said that there was only a small amount of tung oil on the balloon. They just heated it below, and the balloon flew away without thinking about it.

Seeing the balloon flying lower and lower, Xiao Ming was relieved. If tung oil was added to it, he didn't know where the balloon would fly.

Besides, it's easy to hurt people when the balloon falls from the sky. Now that the cultivated land outside the city falls, it's a relief for Xiao Ming.

"Yes, your highness."

The balloon can't fly any more. Lin Wentao jumps off his horse and runs past. A man grabs the balloon's rope.

Xiao Ming nodded, "now you know how hot air balloons fly."

Lin Wentao nodded solemnly, "this balloon flies according to the direction of the wind. If we take the balloon, we can only follow the direction of the wind."

"Well, it's good to understand this. Although you have made a hot-air balloon, it's still the most basic one. The real practical hot-air balloon still needs to be explored. I hope you can put it into practical use one day."

Xiao Ming basically agreed with Lin Wentao by saying that. Now hot air balloon is only the first step.

He continued: "now that the balloon can fly is only the most basic, the next problem you need to study is how to let people ride in the balloon, and look for different wind directions in the air, so as to control the balloon flight."

In the air, the direction of the wind is different at different altitudes. Hot air balloons can only fly according to the direction of the wind, and the speed and wind speed are the same. This knowledge is found in the textbook written by Xiao Ming.

Lin Wentao nodded. He also knew that he had only achieved the first step. He said, "Your Highness, after a while, I will take a hot air balloon to go up to the sky and circle Qingzhou City."

"Hahaha, I'm looking forward to such a day. In this way, the balloon will be a scenery in Qingzhou." Xiao Ming laughed.

For Xiao Ming, he very much hopes that the hot air balloon can serve as a bomber. Unfortunately, it can't do so with the current level of hot air balloon.

First of all, today's hot-air balloons are not hydrogen balloons. Their flying altitude is not high and their flexibility is poor.

Because it's driven by the wind, the balloon can't hover in a certain place, it can only follow the wind.

If you really throw things down, unless there is a suitable wind direction to blow the balloon to the enemy's camp.

After all, it may take a long distance to find the right wind direction for a hot-air balloon to come back after a place has passed, and there are not many people on a hot-air balloon.

Therefore, compared with the extremely inefficient sneak attack on the enemy, Xiao Ming still focused on high-altitude investigation, tourism in Qingzhou City, and another is advertising.

Just imagine how many people would be attracted by a large advertisement hanging on a hot-air balloon.

Xiao Ming has been able to think of businessmen competing to put advertisements on hot air balloons.

The last function of hot air balloon is to deliver information and rescue key people when the city is under siege. Of course, he does not want to use this method one day.

In any case, he appreciated Lin Wentao's courage to try hot air balloons.

It's just that it's going to take a while to wait for the flight.

Let Zhao long and Zhao Hu cooperate with Lin Wentao to put away the hot-air balloon. Soon, the students from the school of physics arrived.

After saluting Xiao Ming, they came forward one after another to help Lin Wentao put away the balloon.

Xiao Ming looks at the busy students with satisfaction. He finally sees a change in them.

And this shift will only become more apparent.

When the students here are busy, Qingzhou City has already been fried. The people coming and going and the merchants coming and going are all pouring to the gate.

There were more and more people around the balloon, and soon the area where the balloon landed was surrounded.

With a strong curiosity on their faces.

Looking at the crowd, Xiao Ming felt that he might be able to popularize scientific knowledge among the people in this hot-air balloon time, which is also an enlightenment to the people's wisdom.In the crowd, Xiao Ming also saw Cao Zhengyang. He was looking at the busy students with a look of amazement. His mouth was wide open.

Since ancient times, people are full of awe of the sky, flying is a distant dream, you can imagine the shock of hot air balloon flying from space.

For businessmen from other places, the hot-air balloon makes them feel more mysterious in Qingzhou, while the king of Qi is more and more unpredictable. From their hearts, they are gradually full of awe for Qingzhou.

The king of Qi could even fly to heaven. What else could he not do.

At the same time, the local merchants were surprised and looked at the foreign merchants. Their faces were full of pride, as if they said, look, this is our Qingzhou. Who dares to say that our Qingzhou is poor.

Seeing that more and more people were gathered around, the soldiers who were guarding the city suddenly came. They sent some people to surround Xiao Ming in the middle, while others scattered the people.

Now the situation in Qingzhou is complicated, and Xiao Ming's safety is the most sensitive string in everyone's mind.

After Lin Wentao sorted out the balloon and let the carriage pull it back, Xiao Ming returned to the city.

It is also the first time that he has seen a hot-air balloon. Although he is very clear about the structure of the balloon, it is the first time that he has seen the real object, so he is also full of curiosity.

On the way back, Xiao Ming and Lin Wentao kept talking.

Lin Wentao initially talked about the next step to realize the use of hot air balloons, while Xiao Ming talked about the use of hot air balloons for high-altitude investigation and the role of other hot air balloons.

Especially when he said that he could still make money from hot air balloons, Lin Wentao became more and more excited, because he felt that the hot air balloon he made was at least not something he could not see and use, and the money was not wasted.

Xiao Ming also promised him that if the balloon could bring income, he would invest all the money in Bowen college.
