Iron Dynasty

Hot air balloons are still floating over Qingzhou.

Lin Wentao and the others were chasing after them, and when they were tired and out of breath, the sound of horse hooves suddenly came.

Come up. Xiao Ming rode his horse to Lin Wentao.

Lin Wentao was stunned, suddenly at a loss.

What are you still doing, if the hot air balloon disappears, this king will not make another one for you. Xiao Ming glared at him and said.

Lin Wentao immediately became anxious when he heard the words, and immediately climbed onto Zhao Long's horse.

Looking at the hot air balloon, Xiao Ming and Lin Wentao chased out, followed by Zhao Long and Zhao Hu.

The hot air balloon kept flying westward, and the rope under the hot air balloon fell down, making Xiao Ming happy that at least this time Lin Wentao made the rope longer.

Maybe this guy flew the hot air balloon like a kite.

Following the hot air balloon, everyone quickly chased out of the city, and the hot air balloon flew lower and lower outside the city of Qingzhou.

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

Seeing the hot air balloon flying lower and lower, Xiao Ming immediately breathed a sigh of relief. If tung oil was added, he didn't know where the hot air balloon would fly.

And this hot air balloon can easily hurt people when it falls from the sky. Now that the farmland outside the city has landed, Xiao Ming is relieved.

Your Highness, catch it.

The hot air balloon could no longer fly. Lin Wentao jumped off his horse and ran over to grab the rope of the hot air balloon.

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

Lin Wentao nodded solemnly, This hot air balloon flies according to the direction of the wind. If we take a hot air 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 now, this is only the most basic hot air balloon. The real practical hot air balloon needs to continue to be explored. This king hopes that one day you can put the hot air balloon into into practical use.”

What Xiao Ming said was basically his approval of Lin Wentao. Now the hot air balloon is only the first step.

He continued: The ability of hot air balloons to fly is only the most basic. The next problem you have to study is how to make people ride in hot air balloons and find different wind directions in the air to control the flight of hot air balloons.

The direction of the wind is different at different altitudes in the air. The hot air balloon can only fly according to the direction of the wind, and the speed is the same as the wind speed. This knowledge is available in the textbooks 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 definitely take a hot air balloon and circle Qingzhou City.

Hahaha, this king is looking forward to such a day. As a result, this hot air balloon is a landscape of Qingzhou. Xiao Ming laughed.

For Xiao Ming, he very much hopes that the hot air balloon can function as a bomber, but unfortunately it cannot be done at the current level of the hot air balloon.

First of all, the current hot air balloon is not a hydrogen balloon, the flying height is not high, and the flexibility is too poor.

Because it is driven by the wind, it is impossible for the hot air balloon to hover in a certain place, and it can only follow the wind hard.

If you do throw things down unless there is a suitable wind direction to blow the hot air balloon into the enemy's camp.

Secondly, you have to throw it accurately. After all, once the place is over, the hot air balloon may need a long distance to find the right wind direction to return, not to mention that there are not many people on a hot air balloon.

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

Just imagine how many people's attention will be attracted if a large advertisement is hung on the hot air balloon.

Xiao Ming can already think of businessmen competing to put advertisements on hot air balloons.

The last function of the hot air balloon is to deliver news and rescue key people when the city is under siege. Of course, he does not hope that this method will be used one day.

In any case, he appreciates Lin Wentao's courage to try a hot air balloon.

Just waiting to take the flight will take a while.

Let Zhao Long and Zhao Hu cooperate with Lin Wentao to put away the hot air balloon. After a while, the students from the School of Physics also arrived.

After they saluted Xiao Ming, they stepped forward to help Lin Wentao put away the hot air balloon.

Xiao Ming looked at the busy students with satisfaction. He finally saw a change in them.

And this shift will only become more pronounced.

When the students here were busy, Qingzhou City was already in a frenzy, and the people who came and went, and the merchants who came in and out all rushed to the city gate.

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

Each with a strong curiosity on his face.

Looking at the crowd of people watching, Xiao Ming's heart moved. He might be able to use this hot air balloon time to popularize scientific knowledge among the people, which is also an enlightenment of the people's wisdom.

In the crowd, Xiao Ming also saw Cao Zhengyang, he was looking at the busy students with a look of astonishment, his mouth could not be closed.

Since ancient times, people have been in awe of the sky. Flying is an unreachable dream. It is conceivable that the hot air balloon floating through space will shock them.

For foreign businessmen, the hot air balloon made them feel that Qingzhou became more mysterious, and King Qi became more and more unpredictable. From their hearts, they gradually became full of awe in Qingzhou.

King Qi can even fly to the sky, and there is nothing else he can't do.

While the local businessmen were amazed, they looked at the faces of foreign businessmen full of pride, as if to say, Look, this is our Qingzhou, see who of you dares to say that our Qingzhou is shabby.

Seeing that there were more and more people surrounding him, the soldiers guarding the city suddenly rushed over. They sent some people to surround Xiao Ming in the middle, while the other part dispersed the people.

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

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

Speaking of which, he was also seeing a hot air balloon for the first time. Although he was very clear about the structure of the hot air balloon, it was the first time he saw the real thing, so he was full of curiosity.

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

Lin Wentao initially talked about the next step to realize the hot air balloon for people, while Xiao Ming talked about letting the hot air balloon carry out high-altitude reconnaissance, and also talked about the role of other hot air balloons.

When You Qi said that he could still use hot air balloons to make money, Lin Wentao became more and more excited, because he felt that the hot air balloons he made were at least not something to be seen and used, and the money was not in vain.

And Xiao Ming also promised him that if the hot air balloon can bring income, he will put all the money into Bowen College.
