In the city of ruins covered by black rain, ashes float silently in the night wind. Xuan Jin, a nameless exile, is burdened with an unspeakable curse - his memory will be burned out every lunar eclipse, leaving only a fragmented ancient legend. Rumor has it in the city that there is a "Heart of Night Ember" buried deep in the ruins, which can reshape one's destiny, but requires the sacrifice of one's soul. Xuan Jin wandered alone among the ruins, searching for fragments of himself, and uncovering the true secrets of the ruins: those forgotten shadow spirits were quietly weaving a new night. His conflict is not life and death, but fighting against his own forgetfulness and dancing with the embers of fate. Every burning memory is a trial of rebirth - Xuan Jin must find his name in the depths of the dark night, or turn it into a new mysterious legend in the embers. The story uses incompleteness and pursuit as clues to highlight the profound resonance between the human heart and ancient ruins, making every wisp of ashes lurk a glimmer of hope.
