I Kill All Enemies with One Sword

This is a world where imperial power is supreme. This is a world where fairies and demons coexist. The high-altitude emperor reigns over the world, the real person flying in the sky and escaping from the earth looks down on the world, and the monsters as high as mountains look at him with eager eyes. Qin Yu, a modern young man, travels to this bizarre world by chance. Let's see how he rises up in adversity and kills all enemies in the world with a three-foot green blade in hand. Stir up the wind and clouds in all directions, climb to the top of the world, and explore the ethereal fairy way.
