Legend has it that, high above the endless heavens, powerful immortal spirits, gods, and demons dwell in the Celestial Kingdom.
The human realm is an accursed land of exile. Every million years, the Celestial Kingdom sends down divine punishment. Darkness blankets the earth, and most living things perish in the ensuing ruin. Those who survive fall into slumber, waiting to awaken at the next dawn!
A young man takes up his sword and pierces the darkness. Light surges forth to meet him, and with a single strike, gods and demons are felled.
A breeze stirs the duckweed, a sword cleaves the clouds. I am the sovereign, and the greatest sword under heaven!
