Carefree Prince In Tang Dynasty

That's right, Li Xin is going to get out an eye-opening aircraft for the big guys, but it's actually a hot air balloon. Although in the original time and space, the world's first manned hot air balloon was born in France, in fact, smart Chinese people have long discovered the basic principles of hot air balloons and used it to make toys, which are known as Kongming lanterns.

To put it simply, the air expands due to heat, and its density decreases. The hot air balloon will experience the buoyancy of a gas in the air. As long as the hot air balloon is large enough, it can carry heavy objects into the sky.

After Li Xin explained, both Situ Liang and Lu Daren were stunned.

The two of them never knew how Li Xin planned to make this "tool" that could carry people to the sky. They thought that this thing had to be thought of, so they were very anxious-what if they couldn't figure it out?

Although Situ Liang had confidence in Li Xin, and at the same time vaguely felt that Li Xin might be truly confident, there was always a slight lack of confidence. Now that Li Xin has said so clearly about the complete vision of the aircraft, its advantages and disadvantages, others are a bit silly.

What does it mean to be confident? This is called being confident.

Li Xin scratched his head. After confirming that he had made it clear, he said: "The top of the hot air balloon, I have also thought about it. Sheepskin should be suitable. The hanging basket below is also simple. Find two bamboo craftsmen to make it. One It can be completed in two days. As for the fuel problem, it is a little troublesome, but the fierce fire oil used in the barracks should be quite suitable..."

Hot air balloons require fuel with relatively high combustion efficiency. And fierce oil, as the name suggests, is a very fierce fuel.

Although Datang is still in the era of cold weapons, and gunpowder is nothing more than a shadow, the "Molotov cocktail" has long been popular. Fire oil is often used when defending the city. This thing was splashed down the city wall, and a torch could send away a dozen or so enemy soldiers who were climbing on the city wall. It was really a must-have for home travel.

Situ Liang and Lu Daren could not help but look at each other as they listened to Li Xin's broken thoughts, and they both laughed helplessly.

The two of them were planning to come and have a big fight, so that they could play their role, which made Li Xin admire them with admiration. Good guy, it turns out that I can't use them at all. Even if they didn't do anything, Li Xin could probably produce high-quality flying equipment on time.

As a future member of the Ministry of Science, the psychological quality must be excellent. Li Xin did not pay too much attention to the emotions of Situ Liang and Lu Daren, and quickly arranged things one by one.

A few days later, the ten-day period arrived.

Since he made a bet with Gui Zhehan in public, when the time came, Li Xin naturally had to come to participate in the early dynasty honestly, so as not to be thought of as fleeing.

Before going to court, Cheng Yaojin asked him whether he had succeeded in making a flying machine.

Li Xin naturally smiled and said, "You wait and see, Uncle Cheng."

In order to give the Minister of Korea and China a complete shock, Li Xin deliberately went to the remote suburbs of Beijing during the test flight a few days ago. It is estimated that even Baiqisi may not know the exact condition of the aircraft.

Li Shimin stepped up the jade steps and slowly sat on the throne. As soon as the ministers finished their salutes, Gui Zhehan couldn’t help but jump out to send out to Li Xin: "Ten days ago, King Chu promised to bring out a reliable aircraft today to open my eyes. I dare to ask Lord Chu if he is ready. ?"
