The Apocalyptic Fairy Mecha

The unexpected encounter between gangsters and savages, the unexpected encounter between advanced technology and traditional magic, they will be a perfect combination just like childhood sweethearts and bamboo horses! As long as your head is strong enough, no one can beat you to death; as long as your mecha is hard enough, no cannonball can defeat you; as long as your face is thick enough... Hehe, you will never lose your face!
