The best way to make a balloon is to make a Kong Ming lantern first.

According to the development of history, the Kong Ming lantern should be invented by Zhuge Liang to transmit military information or large-scale lighting at night.

Lü Bu ordered the cobblers to make bags out of animal skins, and then the carpenters made small lampstands that could hold oil lamps.

When the bags and wooden frames were built, Lu Bu used thin ropes to fix them securely, and then placed the oil lamps.

The leather bag was on a wooden shelf, and the flame was still some distance from the bag when the flame was lit by the flame of the oil lamp.

Everyone gathered around to see what was going to happen.

Standing beside Pang Tong, Chen Zhi asked in a low voice: "Pang Gong, what is Wen Hou going to do?" If you want to set the hides on fire, you don't need to go through the hassle. ”

Although Pang Tong is more intelligent, he does not have the same understanding of the future as Lu Bu after all.

Kong Ming lantern is also an extremely novel thing for Pang Tong.

He pouted and shook his head: "Wen Hou wants to create a novelty, how do I know what it will look like?" ”

Even Pang Tong didn't know what Lu Bu would make, and Chen Zhi certainly admired Lu Bu even more.

It's just that Kong Ming's lantern hasn't really flown yet, and Chen's admiration in his heart is only limited to Lu Bu's daring to think and dare to do.

Squatting next to Kong Ming's lantern, Lu Bu was also drumming in his heart.

The oil lamp had been lit for a while, and the leather bag had not yet bulged.

Just when he was almost in despair, the leather bag moved.

Seeing the bag move, a smile appeared on Lu Bu's face.

The crowd in the crowd also saw the bag move, but the expression on their faces was blank.

Zhao Yun even whispered to Chen Zhi: "If Wen Hou wants to blow the bag up, just blow it with his mouth, why do you want to burn it with fire?" ”

Chen Zhi pursed his lips and glanced at Zhao Yun with an expression of "how do I know".

After waiting for a few more moments, the leather bag on the flame gradually bulged.

The bag grew more and more bulging, and most of the heat from the rising flames was carried into it.

As the heat grew, the leather bag gradually became a ball.

When it was fully swollen, the wooden frame shook and rose from the ground.

Everyone watched in amazement as the bulging bag staggered off the ground with a wooden frame and an oil lamp.

As it completely lifts off the ground, it rises faster and faster.

Gradually, it rose to a height higher than everyone else, and flew up into the air in the night breeze.

Kong Ming's lantern flew higher and higher, and everyone, including Lu Bu, looked up at it as it rose into the air and floated away with the wind.

"How did Wen Hou do it?" Pang Tong swallowed his saliva and asked Lu Bu.

Lu Bu smiled: "Didn't you notice it?" Put your hand on the fire and feel the heat even if you are some distance away. Also, when we burn things, the smoke rises into the air. It is also because of this characteristic of fire that I think that the breath that is burned is lighter than that of the cold. As long as you hold the hot air with something, the balloon will definitely be able to fly. ”

Everyone suddenly admired Lu Bu like a surging river.

"We've all seen fire, we've all seen smoke, but no one ever thought that we could use fire to send things to the sky." Pang Tong asked, "How does Wen Hou plan to name the thing he just made?" ”

"It's carrying an oil lamp, and if a few are released, it can completely transmit military information." Lu Bu said: "As for naming it, I don't think it's too appropriate for me to do it. ”

He then smiled.

Pang Tong was not able to compare with ordinary people, and immediately understood what he meant.

"Since this thing was made by Wenhou, of course it should be named Wenhou Lamp?" Pang Tong said: "In the future, the army can indeed use it to transmit military information." ”

"Wen Hou Lantern ......" Lu Bu pinched his chin and thought for a moment: "I don't think it's good." ”

Pang Tong was suddenly stunned.

Wen Hou is a gift from the Han family to Lu Bu, although when it comes to this title, people think of Lu Bu, but no one knows if there will be people with the same title who will be more prominent than him in the future.

Pang Tong, who understood, immediately said: "Since Wen Hou is not satisfied with this name, then take the name Feng Xiandeng, how about it?" ”

Lu Bu nodded, and a smile appeared on the corner of his mouth: "This name is very good, one is that it corresponds to my font size, and the other is that this name is quite meaningful." ”

"By the order of heaven, take the lead." Pang Tong said: "It really makes sense to choose such a name. ”

He then asked Lu Bu: "Wen Hou said that he wanted to build a balloon that could carry people to the sky, I don't know what it looks like?" ”

"Feng Xian Lantern can go up to the sky, and of course balloons." Lü Bu said: "We can burn a brazier out of coal, and enlarge the skin on the Fengxian lamp hundreds or thousands of times. As long as there is enough heat in the skin, it is not difficult to take a few people to the sky. Then control the height of the balloon by adjusting the amount of hot air in the skin, and use the rudder to control the direction as if it were sailing in water. We will have an air force everywhere! ”

Pang Tong, who lived in the late Eastern Han Dynasty, could not have the concept of the air force after all.

The first time he heard the word "Air Force", Pang Tong looked at Lu Bu in astonishment: "Wen Hou means ......"

"Divine soldiers descended from the sky, that's probably what it means." Lu Bu said: "Shi Yuan can imagine that no matter how tightly guarded the enemy is, it is impossible for him to watch the sky at any time. Even if there were countless balloons flying in the sky, most of them would not have imagined what would be in the balloons. Our soldiers crossed the enemy's defense line in a balloon and launched a surprise attack from behind after landing, how could the enemy defend itself? What's more, if the enemy forces hold on to the danger, our army can also ignore the natural danger and seize the defensive line from them. ”

"If the soldiers can really fall from the sky, who else can stop the temperature from now on?" Pang Tong asked in astonishment.

"As long as I have enough elite soldiers, why is it difficult to dominate the world?" Lu Bu smiled slightly: "Within three years, let the whole world see how I rise and how I trample under my feet the people who once stood above me." ”

"Wen Hou has great ambitions, and we will definitely follow!" Pang Tong responded with Zhao Yun and others.

"The balloon is not a hassle to build, but there are still some technical problems to be solved in the handling." Lu Bu said: "To break through Anhui City, it seems that only flying kites can be used. ”

"A flying kite is supposed to be like a kite." Pang Tong said: "It shouldn't be very difficult to build. ”

"It's not that hard, but how to take off is a problem." Lu Bu said: "People can't drag them like kites on flying kites. ”

Pang Tong nodded.

Let him make plans to conquer the city, he really won't find it too difficult.

But if he wants to develop a flying kite that can carry people into the sky, he is really not that material.

The development of flying kites, Pang Tong, Zhao Yun, Chen Zhi and others can't help at all!
