Accidental time travel. Ruan Yuqing, a 30-year-old urban woman, encountered a landslide while traveling in Guizhou. She accidentally traveled to an ancient Miao settlement and was rescued by the mysterious Miao boy Asa. A mysterious boy, Asa is as handsome as a monster in appearance, but has a gloomy and paranoid demeanor. He shows unusual persistence and possessiveness towards Yuqing, and binds her to him with a silver bracelet. Yuqing tried to adapt to Miao life and learn the language and customs, but Asa's abnormal behavior and control over her made her confused and faintly moved. Asa's brother Aru is hostile to Yuqing and warns her to stay away from Asa, implying that Asa has some unknown secret. Yuqing discovered that Asa was performing a mysterious ritual late at night. When she was peeping, she was discovered. Asa showed supernatural abilities and trapped her in a silver barrier.
