Lin Sanlang, a son of a peasant family in Guanzhong, grew up as a soldier who was forced to join the army against the backdrop of the Tang Dynasty's transition from prosperity to decline. He experienced the border guard career in the Anxi Governor's Palace and the baptism of fire of the Anshi Rebellion. In the struggle between loyalty and betrayal, survival and ideals, he grew into a veteran who saw the truth of the times, and wrote his personal destiny in the rise and fall of the Tang Dynasty.
