This is a kind of thermal weapon originated from China.

It's a hot weapon from China. It can make opponents burn people and give them the nickname "God Arrow".

Divine Arrow is a kind of hot weapon that originated in China and later spread to the Korean Peninsula. It is a rocket launched by gunpowder on a cart with a range of 1 to 2 kilometers. The God Arrow equipped by Sejong King of Korea and the Insect Firearms equipped by Wen Jian Emperor of Ming Dynasty. Originated in the Ming Dynasty in China, individual soldiers used it as a bee colony with firearms, with a downwind range of 100 step (5 feet in the Ming Dynasty is equivalent to 1.65 meters); The rocket is mounted on the carriage as a "fire beast flying gun", which has both offensive and defensive functions. The scattered attack range is about 2 kilometers, and the firepower is quite sharp.

There is also a heavy multistage rocket in the shape of a dragon. There are two magic arrows in Longkou and four magic arrows in the belly of the dragon. After flying continuously for 2 kilometers at a height of three or four feet above the water, the first-stage rocket falls off, and the second-stage rocket ignites, circling around Longkou, which can make the opponent and the ship burn and get out of the water for the fire dragon.

In the Ming Dynasty, firearms were collectively called "magic machine", a special firearms unit was called magic machine camp, and single-tube rockets were called solo rockets. North Korea's arrow is completely different from the solo rocket of the Ming Dynasty. North Korea's magic arrow is an efficient weapon composed of three people, a launcher, an archer and a commander, equipped by the North Korean army.

The practice of solo rocket recorded in the book Wu Beizhi is to use alum paper as a tube, fill it with gunpowder, seal it with fire block oil paper and drill a charging line. Bamboo is the pole, the arrow is dovetail-shaped, and there is no feather. Two or three arrows shoot into the big bamboo tube, which can shoot a hundred paces when the wind is downwind, but it is invalid when used against the wind. It can be used on land and in the sea.
