Deep in the boundless quicksand, Jin Yu, a wanderer who can sense phantoms, is pursuing a desert castle that is said to emerge on the night of a lunar eclipse. The castle is not a human relic, but a place where monsters and nightmares live. Every stone brick hides ancient oaths and curses. Jinyu's fate is closely linked to this phantom castle: she must uncover the truth about the castle within seven days, otherwise her soul will be trapped in it forever. During the journey, Jin Yu formed alliances with sand beasts of various shapes and faced the separation between illusion and reality. Her motivation is not to save the world, but to find her lost self - in the maze of the Phantom Castle, she must learn to talk to the monsters with her heart and resist temptation with her will. The novel uses quicksand as the stage and Warcraft as the language, describing a strange journey about choice and sacrifice, illusion and reality. Jin Yu's story is not only an exploration of the phantom castle, but also a challenge to the innermost loneliness and courage.
