The knights of medieval Europe were almost invincible at the beginning, they were all plate armor at that time, the whole body was tightly protected, the helmet of the head was protected very closely, and there were shields, it was almost impossible for the general infantry without armor to defeat the knights, this armor was very expensive, so at that time there were hundreds of knight troops who could basically hang several times the infantry army, the infantry used spears, swords were basically useless, most of them were sent to death, until this small mace appeared, these knights were unlucky, this mace has a few edges and corners, the production is not very complicated, and it does not use any good steel, and it is okay to use a wooden pole, You don't need to practice swordsmanship, knife skills, you can make a hammer and an axe, just smash it on the knight's head, and smash it without squeaking, because the weight of this mace is almost all in the head, and the inertia is amazing, and the ordinary hammer is different, its edges and corners can gather strength and directly smash the helmet into it.

The development of weapons is the same as that of today's small drones, and cheap weapons have knocked tens of millions of tanks all over the place.
