Who is Zhu Dayou? He is quite a character.
According to Zhu Dayou's own account, his family was once a local powerhouse over a hundred years ago. In the late Qing Dynasty, the Zhu Family even had a Martial Arts Scholar and an Imperial Physician who were renowned and enjoyed a period of great prosperity.
However, this family has gradually declined over the past several decades. By the time it came to Zhu Dayou and his son, they fell into hard times and were only left with a small clinic. Zhu Dayou once dreamed of reviving his family's glory. He studied and practiced diligently, excelling in both medical skills and Cultivation, standing out among his peers.
But in this era, Martial Arts seem to have lost their edge, unless you get involved in the underworld. Otherwise, what's the use of having great martial arts abilities? As someone who regards himself as coming from a "reputable sect," how could Zhu Dayou associate himself with ruffians?
