[Cheerful Nine-Tailed Fox Top × Gentle, Frail, White-Haired Bottom]
Two thousand years ago, during the cataclysmic war between immortals and demons, the Immortal Venerable was defeated after exhausting his strength. As he was about to fall into the cycle of reincarnation, he burned up all his immortal power to forge five spirit pearls, each governing one of the following: life, plants, mountains and rivers, seas and rivers, and the long winds. Together, they reflected the origin of all things in the world. To keep the Three Realms from collapsing, he sealed the pearls within the dragon veins of the five mortal kingdoms, using the mortal world as their prison and its people as their shield, and waited for the fated reunion a thousand years later...
“If there is another life, I ask neither about cause and effect nor what lies ahead. I only hope to meet you again.”
Theme: The sorrow of parting
"The immortal energy of the nine heavens is gradually extinguishing, and the three realms are in mourning..." This is a big bug for the author ~ very good [][][]
