This book uses Boyi's first-person perspective and adopts a dual narrative of "historical witnesses + later generations' reflectors". The opening chapter cuts to the high-suspense scene of "King Yu stabbed in the back". Through the interweaving of flashbacks, interludes and real-time advancement, it shows the magnificent process of the collision of Yi-Xia civilizations, the formation of state machinery, and the birth of the prototype of the Chinese community before and after the establishment of the Xia Dynasty in the 21st century BC.
