! Third update!

When Wanyan Zongjun heard the great King of Yan praise his father, he also smiled, and it sounded very comfortable.

After all, this is the King of Yan, and he is not an ordinary person in the Song Dynasty. Such people praise his father as a capable and capable person, which shows that his father is very powerful.

Of course, this is indeed the case in Wanyan Zongjun's own opinion.

In Wanyan Zongjun's mind, his father's emperor could defeat 100,000 enemy troops, and from this point we can tell how terrifying his father was!

It is the ability and charm of leading troops to fight.

Only the father could lead them to a wider world, defeat the Liao Kingdom, and establish a territory belonging to their Jurchen tribe.

Moreover, this magical battle was just one of them. He and his father had experienced many battles that he had to fail but could not have defeated, but in the end they all won.

Although he thought so in his heart, he still had to be humble. Wanyan Zongjun smiled: "It is also an honor for Father Wu to be praised by King Yan, and King Yan can achieve his current status, which is naturally extraordinary."

"Haha!" The two of them greeted each other for a moment.

Wu Zhi entertained him, after all, this guy made a lot of money for him. In addition to the money entering the treasury, Wu Zhi's accumulated wealth is now extremely amazing, and it has reached more than 20 million silver taels.

Now Wu Zhi has a state of complete wealth and prosperity for money.

He has the power of the Business Department, and he can make money in many things. In addition to the apparent share, Wu Zhi will only make more money if he does some tricks.

However, Wu Zhi didn't want to do too much, because he could share the money with Song Huizong, which already had extremely terrifying gains, and the other Wu Zhi didn't do anything.

If Wu Zhi had to do something, he would probably have all the money from the treasury into his hands.

Wu Zhi was quite loyal to the Song Dynasty.

After seeing Wan Yan Zongjun off.

Wu Zhi just needs to wait for news in the Song Dynasty.

If the 100,000 troops of the Liao Kingdom were defeated, there would definitely be a next move. The decisive battle between them and the Jin Kingdom would soon begin.

During this period, Wu Zhi continued to study his things.

Another half month has passed.

finally.

The first Air Force balloon has been made.

It is a black ball.

It is relatively wide and tall. Below is a round basket wrapped in wood and iron wire that can ride on people. It is connected by thick ropes. After the entire balloon begins to ignite, it will gradually rise.

In ancient times, no one would understand this.

As modern people, this is a very normal thing.

Hot air balloons originate from a very basic principle, hot air rises above cold air.

In essence, hot air is lighter than cold air because the mass of hot air per unit volume is smaller.

1 cubic decimeter of air weighs about 1 gram. If heated to 37.8 degrees Celsius, the weight of the same volume of air will be reduced by about 0.25 grams.

Therefore, 0.25 grams of objects can rise per cubic decimeter of air in a hot air balloon.

But this is far from enough.

This is also why hot air balloons look so huge.

After all, hot air balloons need to be loaded with people, and it takes hundreds of kilograms to sit for a few people. In addition, Wu Zhi must use ammunition, so a large amount of ammunition will be heavier when piled up.

To keep the balloon rising, it is also necessary to continuously heat the air and continuously spit fire.

However, the ignition device made by Wu Zhi and others is relatively rough, but as long as it can be used, anyway, the hot air balloon will fall off slowly and will not die if it breaks.

Of course, if you have bad luck, it would be a big deal.

It's just that the probability is very small.

"Can it rise up?"

Everyone at the scene was very nervous. This was the result of their research for many days!

In fact, these craftsmen did not understand the principle of hot air balloons very well, even though Wu Zhi told them a lot.

For example, how can you fly if you burn it in a balloon with fire?

If you really want to use fire, wouldn’t the balloon be burned?

Wu Zhi told them all these questions.

Because the balloon fabric is a special material, which is resistant to high temperatures and prevents combustion, this problem does not exist.

When the fire ignites, it can rise, and he also told everyone that they understand a little, but they still don't believe that this thing can fly.

The craftsman leader also stared at Wu Zhi's operation.

Since the balloon is deflated at the beginning, someone needs to lift the mouth up, then use the ignition device to blow the air first, and then the balloon expands a few times and then stands upright.

Wu Zhi wanted to teach these people how to control the direction of the balloon, so he sat on it.

And as the fire continued to spit, at this moment, the basket where Wu Zhi was located began to gradually rise.

Everyone looked shocked when they saw this scene.

"Flying up, really flying up!"

The huge black balloon was expanding and bulging. A rising force slowly rose, lifting the basket and Wu Zhi up. It was already one meter away from it.

Everyone's expressions changed repeatedly, as if they had seen a living miracle happening in front of them, impacting their views and thinking.

Then everyone cheered.

"It's so amazing, it's actually flying!"

"This is too amazing, right? King Yan actually made something flying! This is an unprecedented feat... a new invention!"

"Absolutely new invention!"

"I have never seen such a magical thing in my life. It's so amazing that I wouldn't believe it if I hadn't seen it with my own eyes!"

Fei, to ancient people, said that it was out of reach and only existed in the legendary gods.

Now the King of Yan of the Song Dynasty has actually summoned a group of craftsmen to study this kind of thing.

The rising balloon reflected deep in everyone's eyes, and exclaimed incredible sighs.

"So this thing can really fly!"

When the craftsman leader saw the magical scene, he couldn't come back to his senses for a long time. When he came back to his senses, Wu Zhi had already flew four or five meters high.

Suddenly his face changed:

"No! Why is the King of Yan getting taller and taller? How will you get down later?"

Everyone was a little anxious. What if King Yan just flew up and down so much?

If the King of Yan had a crisis, it would be a loss for the Song Dynasty. For a moment, a group of craftsmen were shouting, like ants on a hot pan. The King of Yan only told them that this thing could fly according to his method, but the specific control and whether it could come down was not told to them.

What if this thing keeps rising and drifting in the sky never comes down? Wouldn't that mean that King Yan is going to die in the sky?

I'll wipe it!

Many craftsmen looked panicked. If the King of Yan was gone, they would have the responsibility to be unable to escape.

Moreover, the King of Yan was not bad to them and would take care of them on weekdays. They had delicious food and drinks, and the monthly payment was also large, so many craftsmen were very worried.

But they could only worry, but there was nothing they could do. Who can save people from heaven?
