Jiang Wujiu, an orphan in the mortal world, was sacrificed to the Realm Gate but survived the catastrophe, and thus stepped into the bizarre "Nine Realms Overlapping Domain". Here, spiritual roots are the reward for clearing the dungeon, and the increase in power comes at the expense of emotional loss. When she struggled all the way to the top of the world and faced the ultimate choice between becoming an eternal god and returning to mortal love, she resolutely chose the latter. This is an anti-conventional story about loss, resistance, and holding on to the glimmer of humanity in the face of a grand destiny.
Concept: The world is composed of nine layers of overlapping domains. Each layer is an independent "realm". The higher you go, the denser the spiritual energy and the more cruel the rules.
