When Lu Chen, a retired special forces soldier and archaeological consultant, brought out a lifelike "female corpse" from the tomb of the Millennium Witch King, he thought it was just a serious professional mistake. It wasn't until the girl named "A Ruan" opened her eyes in the moonlight and used ancient witchcraft to block the fatal curse for him that he realized what he had released. She is neither human nor ghost. She is a living sacrifice sleeping in the tomb. She has lost all her memories, but she relies on him instinctively. From then on, Lu Chen's adventure career was turned upside down: she could read inscriptions and control insects and snakes, but she also repeatedly challenged his cognitive bottom line due to her purely "inhuman" perspective. All forces are coveting the secret of immortality, and Lu Chen's only goal has changed from exploring ancient ruins to guarding this "underworld weapon" that drifted from the dark age. He taught her what modernity is and what emotion is; but she quietly healed his deep war scars with her lonely eyes for thousands of years. Until her broken memories gradually revived, pointing to a terrible truth - her awakening was originally an ancient conspiracy designed for "arrival".
