The girl was carried into the underworld as a sacrifice, but the expected cruel fate did not come. On the contrary, Wangui cried and warned, and the Ghost King himself knelt down tremblingly to her on the wedding night, revealing her forgotten, extremely powerful and cold past three hundred years ago - she was the torturer who created the sky lantern that burned the Ghost King's skin and soul for three hundred years. As she revisits her old places (Senluo Palace, Hanging Soul Beam Sky Lantern, Judge's Palace) and touches old things (Sky Lantern, Ancient Files), the protagonist gradually confirms her power and identity, but also falls into a deeper fog: Why did she leave? Why forget? What is the truth about the "Nine Nether Crack" and the "Guardian" that were deliberately erased? The story shifts from escaping fear to pursuing the truth, exploring the protagonist's dark past and unknown future.
