Lu Ren, who originally just wanted to live a stable and peaceful life without peerless talent or understanding of scheming, keeps stumbling upon his sect's secret affairs everywhere. An opponent who fell off a cliff delivers a secret manual, an interrogation scene unearths a corruption token, and accidentally entering a forbidden area yields an ancient rusty sword and swordsmanship inheritance. Life-and-death traps that look perilous step by step in the eyes of others all turn into opportunities by sheer fluke when they fall upon him.
