Lin Wan, a purifier apprentice at Eye of Ashes Outpost, was born with a light silver scar on her palms. This special mark caused her to trigger strange visions of black-robed men and twisted figures when she came into contact with fragments of ancient stone tablets. As the investigation deepens, she discovers a shocking secret from the mysterious diary and dusty files: she is actually the daughter of the last city lord of Starfall City, which was destroyed twenty years ago. She, who was registered as "dead", is actually the "key" that can open or seal the door to other worlds. The concealment of the mentor Gu Hanchuan, the hints of the archivist Granny Su, and the mass mental pollution incident in Fumarsh Town allowed Lin Wan to gradually piece together the truth: the destruction of Starfall City originated from the crack in the gate to the other world, and her mother Lin Jingyi was still alive and was leading the Twilight Society in an attempt to completely open the gate. Lin Wan was forced to embark on the path of pursuit. In the ancient ruins of the northern tundra, she faced the pursuit of deep diver believers, traitors, and her mother's crazy plan. The scar on her palm resonates with the "Heart of Silence" relic. She must make a choice between inheriting her father's sealing mission and following her mother's "evolution" path, protecting the world in her own way and deciding the final direction of the gate to the other world.
