At This Moment, All Mankind Thinks That I Am The Eternal!

The two points Ji Han said are exactly the two most crucial points!

Why did Kongming lanterns have long existed on the land of Kyushu, but it was not until the seventeenth and eighteenth centuries that hot air balloons were officially invented by foreigners and then introduced to Kyushu?

Because these two problems are not easy to overcome!

"First of all, there is the problem of the airbag. If you want hot air to take people to high school, the airbag must have enough airtightness, at least not leak!"

"Secondly, it has to be light enough. If it is too heavy, it will be difficult to fly!"

"In ancient times, if you wanted to make this kind of airbag, it had to be specially made of high-quality cowhide and sheepskin, and the cost was extremely high. Of course, it would be better if you had shark skin!"

After saying that, Ji Han took out two sketches drawn by himself, on which there was a design drawing of a hot air balloon "two three three" paper.

"Nowadays, Daqin is sitting on a large grassland with countless cattle and sheep, and it is best to make this hot air balloon with the best cowhide!

"The cowhide is kneaded and cut, and the craftsmen sew it carefully, and then hang a rattan hanging basket with ropes below! 39

"Finally, the fuel problem has to be solved. You can see that I have designed a burning rack in the middle of this gondola!"

"If you want a hot air balloon to fly, and it is a stable flight, you must have a stable source of fuel, which was very difficult in the Daqin and Daming eras! 99

"The only fuel alternatives that come to my mind are whale oil and oil!

Ying Zheng became interested as soon as he heard it!

He understands whale oil. This thing is said to be extracted from whales stranded in the sea, and it is also called mermaid cream!

A small piece of this thing can burn for a long time, and the heat is high and the flame is large. Many royal tombs will be illuminated by whale oil lamps.

But what is oil?

"Petroleum was called fierce fire oil in ancient times!" Ji Han said: "It is a kind of strange fuel bred in nature. At present, none of you have the ability to extract it, but you can collect it on the surface of many places!

"For example, in Chaoshui, Yumenguan, and a valley near Jiuquan in Gaonu County, Shangjun, you can find this black flammable thing!

Chongzhen nodded immediately upon hearing this!

"What you said is very true!" Chongzhen said: "It's really not difficult to find this thing. In the Song Dynasty, a special weapons supervisor was established to manage the fierce oil!"

"It's not hard to find whale oil, I have a lot of it in the Qin Palace." Ying Zheng said again and again.

Now the fuel problem is completely solved!

Before gas, natural gas and other fuels were developed, whale oil and oil were the best fuels that could be found.

"The last problem to be solved is how to control the size of the flame when the fuel burns, which can be related to the rise and fall of the hot air balloon!

"So I specially designed this burner, which is made of stainless steel, and it can fit an oil storage tank in it, and there is a burner on the top!

"This burner is surrounded by a high fireplace, which is both windproof and allows the flames to be concentrated and sprayed towards the hot air balloon!

"And then, there is also a cover design at the burning port. Covering it will block most of the oxygen from entering, the flame will become smaller, and the hot air balloon can slowly land!"

"After landing, you only need to completely seal the cover and cut off the oxygen, and the fuel flame will be completely extinguished!"

"At the same time, I also designed a blower on the side of the burner, which is similar to a blacksmith's bellows. If you want to accelerate the hot air balloon, you can pull the bellows, and a large amount of oxygen will enter, and the flame will burst into flames. !

Ji Han talked eloquently and explained his exquisite design earnestly. Everyone was fascinated and admired.

This design is really wonderful!

It not only has an unconstrained thinking, but also conforms to the industrial foundation of the Ming Dynasty and the Qin Dynasty, so that craftsmen can rely on existing materials to make it.

"Sir is really a genius!"

"This thing is absolutely feasible, I will let people make it as soon as I go back!"

Ying Zheng Chongzhen trembled with excitement!

They couldn't help but feel excited when they thought that they could create this great killer that dominates the sky.

Whether it is Daqin or Daming, the sky is an unattainable existence, and now they have the opportunity to conquer the sky, they are naturally looking forward to it.

"I just don't know, how much weight can this thing carry?" Wang Ben asked curiously.

"The hot air balloon I designed is about 500 jin, which is 800 jin in Daqin's jin liang. It is absolutely no problem to seat three or four people, and of course there is no need to seat so many people.

"When fighting, there is a manipulator and a thrower on the gondola, and then some food, water, two cans of spare fuel, and two or three boxes of wooden handle grenades!

"Oh, yes, you have to be equipped with binoculars to observe the enemy's situation, and then equipped with a map and compass to prevent getting lost. I will buy you thousands of compasses when I have time!"

"Also! Be careful in case the hot air balloon fails and crashes, you can let the craftsman sew a kind of clothes similar to bat wings! 99

"In the event of a crash, immediately let the soldiers jump off the hot air balloon, spread out their limbs, and then glide and land like a bat.

Ji Han talked eloquently, wrote and drew on paper from time to time, and shared his thoughts and details, which made everyone stunned.

Is this all possible?

If you follow this series of operations, it seems that there is really no difficulty.

All the difficulties have been resolved, go back to the craftsman to build this thing, and the fool can fly into the sky.

"Awesome, the thoughts and thoughts of the first 4.3 students are really convincing!

"Yeah, such a fetish, only a gentleman can think of it!"

"With the help of this hot air balloon, it is easy to destroy Baiyue!

The crowd praised and sighed again and again!

The splendor in Wang Mushi and Yang Zi's beautiful eyes is also getting stronger and stronger.

The kung fu of a meal adds another great weapon to Daqin, which not only increases the strength of Daqin's army, but also promotes the development of the times.

Who else can do this but a sage?

"Sir, after giving pointers to the first emperor, you have to point me this time, right? Chongzhen said sourly: "You can't be partial.
