Male lead: Lin Fan. He seems simple-minded and only average in talent, but inside he's theatrical, scheming, and a master of the sly underhanded move (he likes to ambush people, hide his abilities, and catch others off guard). He binds himself to a [Super Sly-Goofball System].
System: The missions it issues are often incredibly ridiculous (for example, stealing a sect elder's wig and wearing it on your own head for half an hour, drawing a perfect circle with your butt in the middle of the sect's main square, or singing and dancing a love confession to the sect's sacred beast). The rewards are generous, but completing the missions is mortifying or requires top-tier sneaky skills. Its core function is to help the male lead keep a low profile and ambush people.
Female supporting character: Liu Qingxue. Lin Fan's childhood sweetheart. She looks pure and charming, but is pragmatic and self-serving inside. Believing Lin Fan has no future, she switches her allegiance to a more promising prodigy from another sect.
Male supporting character (main antagonist): Chu Feng. The sect's senior disciple and a heaven-blessed talent from the greatest sect. He appears gentle and upright, but is actually narrow-minded and profoundly hypocritical. Jealous of a small opportunity Lin Fan happened upon (which was actually just the pretext for a System mission), he joins forces with Liu Qingxue to frame him.
Why can he still hang around in the sect after he was expelled from the sect?
