When did the earliest muskets appear?

The earliest musket was first invented in the Song Dynasty. 1 132, nomads go south. De 'an Prefecture (now Anlu County) adhered to the old rules and created the world's earliest tubular shooting firearm, named "musket". It uses a thick and long bamboo tube as a barrel, which contains gunpowder. In the face of confrontation, the line of fire was ignited, and gunpowder ejected from the gun barrel to burn the enemy soldiers. This musket must be carried by two people. In the defense of De 'an, more than 20 muskets with long bamboo poles were used to shoot the enemy soldiers who attacked the city from the bridge, forming a fire wall that the enemy soldiers could not break through.

At 1259, the earliest musket capable of firing "Zi Zhen" in China appeared again. This gun is improved on the basis of musket. It also uses giant bamboo as a barrel, which contains gunpowder and a "sub-nest". When detonated, it spewed out a "sub-nest" at the same time as the flame. The so-called "sub-nest" is a bullet nest filled with porcelain pieces, broken iron pieces and stones, which is the predecessor of the projectile fired by tubular firearms later. At present, there is an earlier metal musket in China, which is a copper spear made by 135 1 This bronze spear is 3 cm in diameter, 44 cm in length and weighs 4.25 kg. There is an inscription on the spear that says "Shoot through a hundred holes and vibrate for nine days". It was a firearm used by the cavalry at that time.
