Lao He has had a dream since he was a child, to one day be able to spread his wings and fly high.
When I was a child, I was beaten too many times, so I just wanted to turn into a little bird and fly to the sky, and no one would be able to control me anymore.
To put it bluntly, I just want to play tricks on God.
He Yunlong, Yunlong Yunlong, only God can call him Yunlong!
Otherwise, it can only be regarded as a worm underground.
After Zhang Bao got the gunpowder, he did have a way to let Lao He go to heaven once, but it was difficult to do it when he came down.
Moreover, Zhang Bao has also been studying a problem recently. Hezhou now belongs to him, but the area of Hezhou is too large.
The timeliness of this information is still too low, and with such a long distance, even if they continue to use this method of sending messages through smoke and smoke, it will be troublesome.
So Zhang Bao has been studying the problem of hot air balloons recently.
After all, if you ask Zhang Bao to build a plane, it is absolutely impossible.
There are too many barriers to knowledge, and it is absolutely impossible for Zhang Bao to overcome them alone.
But the structure of a hot air balloon is relatively simple.
With a hot air balloon, you can walk in a straight line in the air, and the distance can be shortened a lot.
And there are many applications of hot air balloons on the battlefield.
Just imagine, floating to the middle of the battlefield on this hot air balloon, and then throwing explosive packets down from the hot air balloon, you would be invincible.
And in this way, the city wall and so on will lose their meaning.
There is no means of air defense now, the only thing that can be used is bows and arrows, but as long as they are maintained at a certain height, these bows and arrows cannot pose any threat to the hot air balloon at all.
The first Montgolfier brothers used paper and cloth as materials, connected these materials with buttons, filled the balloon with hot air, and then flew.
Even if there is no such thing as hydrogen now, it can still be done simply by relying on hot air, just like the Kongming Lantern.
In fact, it is an enlarged version of the Kongming Lantern.
It just needs to add methods to control the flame and travel.
The only difficulty lies in the materials.
The paper is definitely not good anymore. The current paper is not only rough, but also contains impurities and does not have good ductility. For the airbag of a hot air balloon, such a large area must be sewn.
When Zhang Bao was using fabric, he found that the fabric was so breathable that it could not trap hot air at all.
Finally, Su Xiaoyue thought of a way.
Su Xiaoyue had thought about this problem before when she was making a raincoat for Zhang Bao. The reason why that kind of raincoat is rainproof is because the layers of leaves of the raincoat are closely together, so that they can be waterproof.
But it is very inconvenient to wear it like this.
Xiaoyue used some densely woven cloth and applied a layer of paint on the outside of the cloth. This paint was actually the kind used to decorate concierges.
However, when using this paint, it also caused the softness of the entire fabric to change, making it very uncomfortable to wear, so it was not used in the end.
After hearing about the difficulties Zhang Bao encountered, Su Xiaoyue expressed this idea.
Zhang Bao tried it according to Su Xiaoyue's words, and sure enough, the cloth became airtight after being painted with paint.
Zhang Bao was overjoyed.
On this day, after Lao Hecai came back from buying wine, he saw a strange thing in his yard.
On top is a piece of highly bulging cloth, with a basket tied underneath.
There is a sheep in the basket.
"What are you doing?"
"Flying Roast Lamb?"
Lao He asked with a shocked look on his face.
"Uncle He, where were your previous dreams and pursuits?"
"How come all that's left now is eating, drinking, and having fun?"
Zhang Bao looked down upon him.
"I plan to let this sheep fly into the sky, do you believe it?"
Zhang Bao smiled and said to Lao He.
"Fly into the sky?"
"What are you doing with this bullshit?"
"How can a sheep go up to the sky without wings? Let alone put it in a basket."
Lao He said very dismissively.
Isn't it normal for you to want to go to heaven when you are young? When I was young, I also wanted to pick the moon for fun. Now that I am old, I am very knowledgeable and do things very appropriately. Do you think you are the same as you young people?
Seeing Lao He's disdainful eyes, Zhang Bao grinned.
"How about another gamble?"
"Oh, let's forget it, you won't admit it even if you lose!"
"Watch it, I'm going to light it up!"
As Zhang Bao spoke, he lit a huge candle on the shelf.
An hour later...
The balloon finally inflated under the filling of hot air.
There is nothing that can be done about this. After all, the amount of heat increased by a single candle is limited. Even if Zhang Bao specially made this candle with animal fat, the flame will be under the action of the thick rope, which will be very big.
, but after all, the size of this hot air balloon is there.
It burned for a full hour before the hot air filled the entire air bag.
"Uncle He!"
"Look!"
Zhang Bao excitedly punched Lao He who was snoring next to him.
Lao He woke up in confusion.
"What's up?"
"What's wrong?"
"Is the roasted lamb ready?"
Lao He asked quickly.
As soon as he finished speaking, he saw a shocking scene in front of him.
I saw that the basket containing the sheep in front of me was lifting slightly from the ground.
Slowly, it flew higher and higher, and eventually, it was already above his head.
Lao He was dumbfounded.
"What's going on?"
"Why did the sheep fly?"
Lao He was shocked.
"Uncle He, you hold this one first, and I'll get the tree pole and put a few more sandbags on it!"
As Zhang Bao spoke, he gave the rope holding the hot air balloon to Lao He.
In fact, Zhang Bao had anticipated the rise, but the problem was the decline. How to control this decline was troublesome.
If people are on top, they can also control the rise or fall by controlling the size of the flames. But now there is only one sheep on top. If you want to control the height, you can naturally only add heavy objects to it.
But when Zhang Bao came back with sandbags and tree poles, he found that Lao He and the hot air balloon were missing.
"You little bastard, just wait for me!"
"Watch if I don't beat you to death when I get down!"
At this moment, Lao He's voice came down from the sky.
Zhang Bao looked up.
I saw Lao He clinging to the rope and being carried into the air by the hot air balloon.
