Hot air balloons are just ordinary things when they are placed in the virtual world and the world before Zhao Hongyu.

Anything that has some conditions and skills can be done by ordinary people.

Of course, the size may not be necessary.

And ordinary people don’t have that much spare money.

But if hot air balloons are placed in this time, space and era, it is a very remarkable thing.

Although humans in this era yearn for the sky very much.

But in this era, humans have not yet mastered the technology that can rise into the air.

Even the "qinren" dare not even think about this.

However, this kind of thing has been experimented with in the Song Empire established by Zhao Hongyu in the Americas.

"Actually, it's very troublesome to get this hot air balloon. It's better to have a simple plane than to have such a leisurely mind. And it doesn't seem to be very useful to get the hot air balloon."

After looking at the hot air balloon, Professor Liu turned around and said to his son-in-law Song Hu.

Yes, Professor Liu actually felt that it was a bit inappropriate for Song Hu to get a hot air balloon.

Hot air balloons are not very useful to them, and he can't think of any place to use them.

However, because Song Hu is his son-in-law and Song Hu is very concerned about this matter, he has never opposed it since the incident began.

However, now that the hot air balloon has been made, Professor Liu can't help but complain to Song Hu.

In his opinion, this is a waste of money and time.

After hearing this, Song Hu smirked silly. He seemed to have not taken his father-in-law's complaints to heart.

"My father-in-law, you can't say that. In fact, it's not useless after you get the hot air balloon." Song Hu retorted a little about his father-in-law Professor Liu's complaints.

How can we say that hot air balloons are useless?

It wasn't a whim to think about making this thing.

It will definitely be useful if it is made.

"Oh, then tell me, where do you want to use it?"

Professor Liu rolled his eyes and asked Song Hu back.

"My father-in-law, we can't get the plane at the moment. But hot air balloons are still OK. And after the hot air balloon is made, it will be very useful for military reconnaissance and geographical observation, right?"

Song Hu's words are not aimless. If he really said this, then this hot air balloon is really of great use.

Hot air balloons are used for military reconnaissance and geographic observation, which is a really good choice.

Think about it, if there are hot air balloons in the Imperial Army, then when encountering enemies and fighting, the hot air balloons will be raised into the air. You can basically see the environment around the battle site clearly.

If the enemy wants to keep the reserve team or something, they will find out in advance.

This will be of great benefit to our side.

Although the Song Empire is very stable now, the Imperial Army on the American Continent will occasionally fight with some Indian tribes that have not defected to the empire.

It’s just that these Indian tribes don’t pose much threat, so they are not taken seriously by the empire.

But even if America has no rivals, what if it is Europe?

At present, the empire mainly focuses on development. But when the empire develops to a certain extent, it will definitely launch a war of aggression against other countries.

Therefore, hot air balloons are of many use.

This is used for some military considerations.

In addition, if you use hot air balloons, you can also conduct geographic observations.

Observing the geographical environment in the air is actually as important as observing the geographical environment on the ground.

If you want to make a sand table, it will be much more convenient to have the help of hot air balloons.

Thinking of these uses and benefits, Professor Liu nodded, acknowledging these aspects that Song Hu considered.

"Okay, what you said satisfies me. I didn't think so much, and I didn't expect you to think so carefully."

Professor Liu, who knew that he had thought wrong, pretended to be serious and praised him in order to hide his embarrassment.

Zhao Hongyu still giggled in a silly way.

"According to your opinion, I actually think if I continue to develop Ontario City in the future, I can also use hot air balloons. If I look at the changes in the current city streets and some terrain environment in the air, it will also help the city plan again in the future, I can make some more detailed considerations."

Professor Liu thought a lot, and he suddenly thought that if the hot air balloon was really successful, it would be of great benefit to considering urban planning.

The reason is very simple, Ontario Cheng's development and construction have not stopped.

Construction sites are starting almost every day.

Therefore, for Professor Liu, who is in charge of urban construction planning, this is a matter that has to be carefully considered.

Residential areas, parks, infrastructure areas, public units, and even streets all need to be confidently considered in the planning before a detailed plan can be made.

At the same time, the geography and terrain of the construction area must also be considered.

Therefore, if you sit on a hot air balloon and come into the air, Professor Liu can have an intuitive understanding of what Ontario City is now.

This is of great benefit to his future planning plan.

"You are right, my father-in-law. There are indeed such benefits with hot air balloons, so my father-in-law won't say that I'm messing around this time."

Song Hu smiled and said Professor Liu a little embarrassed.

He didn't even think of something that Song Hu could think of.

He always thought that Song Hu was so idle that he would focus his energy on it out of boredom.

Now he realized that Song Hu was not making a fool of himself.

If this hot air balloon project is really done, it will be of great benefit to both yourself and the empire.

And Song Hu said something right. That is, with their current technical level, they can only get a hot air balloon project. As for aircraft, it is simply unrealistic.

You know, the technology required to build an aircraft, even the very old-fashioned one, is quite considerable.

But hot air balloons are much simpler.

Therefore, Song Hu is now a very correct choice to get a hot air balloon.

As for the plane... I will only talk about it after a few years.

However, judging from the current development speed of the empire, it is really not difficult to have something like an airplane that transcends the times.

Who made the ruler of the Song Empire? Zhao Hongyu, who was far away in the east, possessed a cheating device that was against the will of heaven.

At this time, a guy who had been selected had jumped into the basket woven by rattan. The guy's face was full of excitement and anxiety. You can also see fear and panic in his eyes.

Yes, no one knows whether this hot air balloon will actually fly into the air and can land safely.

Hot air balloons are not without dangers and safety risks.

The one who was selected as the experimenter was an Indian male with dark skin.

The reason why he was selected was mainly because he had a lot of revenge as an experimenter.

300 imperial silver coins are the salary of ordinary people for more than two years.

The used fire-breathing device purchased from the virtual world is still spraying flames.

Even the fuel is purchased from the virtual world.

I have to say that Zhao Hongyu has opened up permissions to Song Hu, which is really convenient.

Of course, Song Hu had thought about it. He bought a cheap plane and came back.

Unfortunately, Chen Zhenbang was not concerned about this matter at all, and Zhao Hongyu and others were unable to contact other people in the virtual world except Chen Zhenbang.

Therefore, Song Hu had to come up with a hot air balloon.

Because of Chen Zhenbang's relationship, Zhao Hongyu, Song Hu, Wang Shan, Zhang Tie and others have complained in their hearts more than once.

If they can contact the Mi Empire in the virtual world, they will not have to worry about this.

You should know that the Mi Empire in the virtual world is the same as the time and space where Zhao Hongyu had not come to this era before. As long as you have money, you are the old man and you can buy anything you want.

Compared with the virtual world where Chen Zhenbang lives, it is really a paradise.

Because Chen Zhenbang is from the Chinese, Zhao Hongyu can't buy many things even if he has money.

Even those that can be bought are all the junks that Chen Zhenbang had blacked them.

Either things are about to be scrapped, or they are brought from the scrap recycling station and sold to Zhao Hongyu at a high price. Even the prices of these things are even more expensive than brand new ones.

It's really a fool.

However, without Chen Zhenbang, Zhao Hongyu would not be able to purchase goods from the virtual world.

It is precisely because of this helpless reason that Zhao Hongyu and the others can only accept Chen Zhenbang's exploitation.

It's strange that Zhao Hongyu's cheating device stipulates that he can only trade with Chen Zhenbang.

It's impossible to replace people at all!
