Historical mystery: During the Tiansheng period of the Northern Song Dynasty, Feng Tao, the leader of the Five Righteousnesses, was involved in the fight for the Jade Tiger Talisman, and mysteriously evaporated before the rift in time and space, leaving behind the prophecy of "the blood moon appears, the tiger talisman returns".
Modern case: Northern Song Dynasty-style arrows appeared at the explosion site of the Quantum Laboratory. The victim had cinnabar tiger stripes on his forehead, which is consistent with the "Tiger Talisman Sacrifice" ceremony recorded in ancient books.
Dark threads intertwined: The Black Star Chamber of Commerce obtained the incomplete star map through archaeological excavation and tried to use blood sacrifice to restart the Jade Tiger Talisman. Agent Li Gongfu of the Space and Time Administration intervened in the investigation through "resurrection".
Technology puzzle: Mei Aoxue discovered that her time travel was no accident. The nanochip implanted in her brain actually contained Feng Tao's DNA memory fragments, and she gradually awakened to the ability of ancient machine arts.
