Crossing Wu Dalang starts from selling cakes

Chapter 309 The hot air balloon really flew!Three more!

Hearing the majestic King Yan of Song Dynasty praise his father, Wanyan Zongjun also smiled, which sounded very comfortable.

After all, this is King Yan, and he was not an ordinary person in Song Dynasty. Such people all praised 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 several thousand people can defeat the enemy's 10 troops, and from this point he knows how terrifying his father is!

That is the ability and charisma to lead troops into battle.

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

And this miraculous battle was just one of them. He followed his father and went through countless battles that were supposed to fail and were impossible to win, but in the end he won them all.

Even though he thought so in his heart, he still had to be humble. Wanyan Zongjun smiled and said, "It's an honor for Emperor Wu to be praised so much by King Yan, and it's a great honor for King Yan to achieve his current status. .”

"Hehe!" The two exchanged pleasantries together for a moment.

Wu Zhi entertained him for a while. After all, this product made him a lot of money. Apart from the money that went into the national treasury, Wu Zhi's accumulated wealth is extremely astonishing, reaching more than 2000 million taels of silver.

Now Wu Zhi can be said to be in a state of no shortage of wealth when it comes to money.

He holds the power of the Commerce Department under his hands, and he can earn money from many things, except for the superficial share, if Wu Zhi does something, he will only earn more.

However, Wu Zhi didn't want to do too much, because he could already have extremely terrifying benefits if he could share with Song Huizong, and the other Wu Zhi didn't play tricks.

If Wu Zhi had to do something wrong, he might be able to get all the money from the treasury into his hands.

Wu Zhi is still relatively loyal to Da Song.

After sending off Yan Zongjun.

Wu Zhi only needs to wait for news on Da Song's side.

The [-] troops of the Liao Kingdom were defeated, and there must be another move. At that time, the decisive battle between them and the Kingdom of Jin will begin soon.

During this time, Wu Zhi continued to study his stuff.

Another half month passed.

at last.

The first Air Force balloon has been built.

It's a black ball.

It is relatively wide and tall, and below it is a round basket wrapped with wood and iron wires that can take people. It is connected by thick ropes. After the whole balloon starts to ignite, it will gradually rise.

In ancient times, no one would understand this.

For modern people, this is a very normal thing.

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

Essentially, hot air is lighter than cold air because hot air has less mass per unit volume.

1 cubic decimeter of air weighs about 1 gram, and if heated to 37.8 degrees Celsius, the weight of the same volume of air will decrease by about 0.25 grams.

Therefore, each cubic decimeter of air in a hot air balloon can lift 0.25 grams of objects.

But this is far from enough.

This is also why hot air balloons look so huge.

After all, a hot air balloon is supposed to hold people, and it would weigh several hundred catties if it sat a few people. In addition, Wu Zhi would definitely use ammunition, and a large amount of ammunition would be even heavier when piled up.

To keep the balloon rising, it also needs to continuously heat the air and continuously spray fire.

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

Of course, if you are unlucky and fall into the enemy's camp, that's a fart.

It's just that the odds are small.

"Can it rise up?"

Everyone at the scene was very nervous, this is the result of their many days of research!

In fact, these craftsmen don't really understand the principle of hot air balloons, even though Wu Zhi told them a lot.

For example, if a balloon is burned with fire, how can it fly?
If you really want to use fire, the balloon will be burned or something.

Wu Zhi told them all these questions.

Because the balloon cloth is a special material, which can withstand high temperature and prevent burning, so this problem does not exist.

And the fire can rise when lit, he also told everyone this.They understand a little bit, but they still don't believe that this thing can fly.

The man who was the leader of the craftsman also stared at Wu Zhi's operation.

Since the balloon is deflated at the beginning, someone needs to lift the mouth, and then use the ignition device to spray fire and blow air first. After a few times, the balloon inflates 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, at this moment, the basket where Wu Zhi was in began to rise gradually.

Everyone was shocked when they saw this scene.

"Flying, really flying!"

The huge black balloon was inflated and bulging, and a rising force rose slowly, lifting the basket and Wu Zhi up.It is already a meter high from inside.

The expressions on everyone's faces changed again and again, as if they saw a living miracle happening before their eyes, impacting their three views and thinking.

Then, everyone cheered.

"It's amazing, it actually flew!"

"Isn't this amazing? King Yan actually made something that flies! This is an unprecedented feat... a new invention!"

"Absolutely new invention!"

"I've never seen such a miraculous thing in my life. A large piece of cloth can be circled, and it can fly when it is ignited underneath. It's really amazing. If I didn't see it with my own eyes, I wouldn't believe it!"

Flying, for the ancients, it was out of reach, and it only existed in the legendary gods.

But now King Yan of the Song Dynasty actually summoned a group of craftsmen to research this kind of thing.

The rising balloon was reflected in the depths of everyone's eyes, and they sighed inconceivably.

"It turns out that this thing can really fly!"

The man who was the leader of the craftsman saw the miraculous scene, but he couldn't recover for a long time. When he recovered, Wu Zhi had already flown four or five meters high.

Suddenly his expression changed:
"Not good! Why is King 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 like this?
If there is a crisis in King Yan, it will be the loss of Song Dynasty. For a while, a group of craftsmen shouted like ants on a hot pot. King Yan only told them that this thing can fly according to his method, but how exactly? Manipulation, whether it can come down, this point was not told to them.

What if this thing keeps rising, drifting in the sky and never coming down?Doesn't that mean that King Yan will die in the sky?

I rub!

Many craftsmen were flustered. If the King of Yan was gone, they would not be able to escape the responsibility.

Moreover, King Yan treated them well, and he would take care of them on weekdays. They had delicious food and drink, and the monthly money they handed out was quite a lot, so many craftsmen were very worried.

But they can only be anxious, but there is nothing they can do. Who can save people in the sky?
