Yun Gui was originally a lantern holder in the fairy world, responsible for day and night in all realms. Because of his obsession that "everything not illuminated is night", he violated the rules of heaven and was expelled from the world, living in the mortal world. It's night for everyone, only the clouds return to see the traces of day, looking for light in the world of mortals. However, the embers of the fairy world are lurking quietly, trying to use Yungui's remaining lamp to rekindle the old power. Those who live in hiding in the mortal world also have a glimpse of the secret of its light, hoping to break the limit of reincarnation. Yungui wanders between the desires of sentient beings and the shackles of heaven, both as an exile and as a guide for passers-by.
In the vast world, he used the wick as a guide to pursue the "ownerless light" - the legendary fire that can ignite a new era. Every time the lamp is lit, the subtleties of the human heart and the cracks in destiny are illuminated. The story uses Yun Gui's journey of exile as a clue, intertwining the legacy of ancient immortals, the sorrows and joys of the world, and the struggle against destiny. Light and darkness are entangled with each other, revealing the true nature of all living beings in the world. This book does not ask about becoming a fairy or a demon, but only asks whether you can find a glimmer of light for all things in the eternal night.
