In the history of our country, there are many talented people. As we all know, Lu Ban was a great inventor in the Spring and Autumn Period in China history. He is very clever and likes to delve into some strange things. His hands-on ability is also very strong, and he can often be inspired by things in life, thus developing something. Of course, these things also have certain functions, and these inventions also facilitate people's lives. For example, our common saws can be used to saw wood, which greatly facilitates people's lives.

Luban not only invented the saw, but also invented the first unmanned aerial vehicle in the history of China. The drone invented by Luban is called pastoral. It is made of bamboo and wood. Shaped like a magpie, it is called a wooden sparrow. This wooden magpie is also quite remarkable. According to historical records, it can fly in the sky for three days and three nights without falling. This may sound exaggerated, but it does exist in history.

It is a great pity that the UAV invented by Luban has not been handed down in the end. The reason why it didn't spread was entirely because of Mozi. Mozi was also an inventor of that era. After Lu Ban invented the wooden magpie, he showed it to Mozi. After reading it, Mozi thought it could only fly in the sky and had no practical use, so he didn't care too much. As a mocking blow to Lu Ban, Lu Ban was not interested in seeing Mozi at all, and never put his mind on it again.

At that time, technology was underdeveloped, and there was no such energy as gasoline and natural gas, but it was amazing to fly. It can be seen that the UAV at that time was just a mechanical structure, allowing it to fly with the help of natural forces. This shows how amazing the structure of this drone is. Although it is not as exaggerated as three days and three nights, it is indeed a great invention.
