[recommendation] need a manhwa surrounding zhongnan sect

I'm writing a dnd campaign based on murims and my friends have decided on the Zhongnan sect disciples to play as. I haven't read any series where the main focus is the Zhongnan sect so as to write better (*ahem* I'm lazy *ahem*) i need a manhwa surrounding the Zhongnan sect. I need a manhwa whose main character is a disciple/a major part of zhongnan sect.
