Chang'an************

Modern forensic doctor Ling Yue traveled into Chang'an with a mysterious bone pendant, used post-mortem skills to solve the poisonous case, and helped Li Shimin survive the Xuanwumen Incident. However, he found that the pendant contained modern symbols - the poisonous eggs were suspected to be related to his grandfather's sudden death, and they also had the same origin as the fragments of Su Qinghuan's grandfather, who knew poisonology. Different from ordinary time-travel detectives, this book uses the mysterious bone pendant to connect the time-space closed loop of the Gu nest in the late Sui Dynasty, Chang'an conspiracy, and modern unsolved cases. It uses forensic medicine and southern Xinjiang toxicology to break the situation, and unravel the truth about time-travel and the destiny of the pendant at the real historical node. Every corpse hides secrets across time and space.
