Little Princess of the Six Realms [Extras]

He was the ruler of the human realm, yet because of a demon princess, he would never enter the cycle of reincarnation. Year after year, he loved her but could never have her, suffering the agony of longing.

It is easy for a human to cultivate immortality, but hard for a ghost. To keep from forgetting her, he spent ten thousand years cultivating from a soul into an immortal, all so he could stand by her side with his head held high.
