Ring Gear

The nine-ring world is like a giant wheel with teeth, biting layer by layer, crushing ants. Six-year-old Lin Xuan climbed out of the pile of corpses in Rotten Rat Alley and learned his first lesson in the arena: either be crushed by gears, or become sharper teeth. He used his body blade to pierce this bloody machine that devoured all living beings, vowing to make it break apart inch by inch starting from his own tooth.
