Modern history scholar Li Congxin died suddenly while explaining "The Limits of Humanity in the Five Dynasties and Ten Kingdoms" and was reborn as a 5-year-old orphan in the troubled times of the late Tang Dynasty. He was adopted by Shatuo hero Li Keyong and named Li Chengying, becoming one of his many adopted sons.
This book centers on the tearing of the protagonist's dual identity - a modern soul and an ancient assassin - and deeply explores how violence is rationalized by the system and individuals' struggles and choices in the torrent of history.

The plot is closely linked and fascinating
