In the last years of Jiaqing, the five branches of the Guan family in Jianglin Town were engaged in business separately. The eldest son Guan Yuance was the least prominent and lived in a deserted medicine shop. His son Guanze watched his uncle encroaching on him step by step, but his father gave in and secretly vowed to take back everything that belonged to the eldest son. He didn't expect that this seemingly peaceful town was already turbulent in the dark.
