In the 16th year of Yongchang's reign, there was a severe drought in the north. The medical girl Song Qinghe and her young brother encountered a refugee riot while fleeing famine, and were rescued by the mysterious young man Gu Zhao who was seriously injured. One is a declining medical girl who was expelled from her family, and the other is a Jianghu guest who carries the secrets of the former dynasty. On the road of exile where people are starving and dying, the two go from being wary of each other to trusting each other in life and death. When the Bronze Wolf Sword encounters the "Green Bag Fragments", and when the secret of the strange pupils breaks through the previous edict, this escape actually leads to the shocking conspiracy of twenty years ago. Tempered by blood and fire, they used herbs and swords to carve out a paradise in troubled times.
