Carefree Prince In Tang Dynasty

That's right, the aircraft that Li Xin is going to create to open the eyes of everyone is 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 discovered the basic principle of hot air balloons and used it to make toys, that is, Kongming Lanterns.

To put it simply, the air expands when heated, and the density decreases, and the hot air balloon will be buoyant by a gas in the air. As long as the volume of 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 didn't know how Li Xin planned to make this "tool" that could carry people to the sky, and they thought that this thing had to be imagined, so they were very anxious-what if they couldn't figure it out?

Although Situ Liang had confidence in Li Xin, at the same time he vaguely felt that Li Xin might be really confident, but he was still slightly uncertain. Hearing Li Xin explain the complete vision of the aircraft as well as its advantages and disadvantages so clearly, he felt a little silly now.

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

Li Xin scratched his head, and after confirming that he had made it clear, he said, "I have also thought about the top of the hot air balloon. The sheepskin should be quite suitable. The hanging basket below is also simple. Find two bamboo craftsmen to weave it. It can be completed in two days. As for the fuel problem, it is a little more troublesome, but the kerosene used in the military camp should be quite suitable.”

Hot air balloons need fuel that burns more efficiently. And fierce fire oil, as the name suggests, is a very strong fuel.

Although Datang is still in the era of cold weapons, and gunpowder is not even a thing at all, "molotov cocktails" have long been popular. When defending the city, fierce fire oil is often used. This thing is poured down from the city wall, and adding a torch can send away a dozen enemy soldiers climbing on the city wall. It is really a must-have item for home travel.

Situ Liang and Lu Daren listened to Li Xin's thoughts, and couldn't help but look at each other, both smiling helplessly.

The two of them originally planned to come to do a big job, to play a good role, and to impress Li Xin. Boy, it turns out there's no use for either of them. Even if they don't do anything, Li Xin will probably be able to produce high-quality flying equipment on time.

As a future member of the science department, the psychological quality must be excellent. Li Xin didn't 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 had to attend the morning court honestly, so as not to be thought to be running away.

Before going to court, Cheng Yaojin specifically asked him if he had succeeded in making the aircraft.

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

In order to completely shock the ministers of the DPRK and China, 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 jumping out and complaining to Li Xin: "Ten days ago, the King of Chu promised to open my eyes with a reliable flying machine today, and I dare to ask the King of Chu if he is ready. ?”
