Sword Rules the World

[Classic xuanhuan, overpowered protagonist, fast-paced, ruthless, cunning and funny] One man, one sword: he can cut through heaven and hell! I wield a sword that can open the gates of heaven! Emerging from the untamed wilderness, I swept through the ages with the three-foot sword in my hand. I rose from the depths of despair and was reborn there. When my sword strikes, immortals and demons flee; when it falls silent, mountains and rivers mourn!
