- Protagonist: Lin Fan, a reclusive martial arts master in the city, with unfathomable strength (levels of breaking walls with one punch and walking through the air), upright character, and a strange mind. He does not understand the rules of modern society. When doing things, he only cares about "whether the result is right" and completely ignores "whether the process is good or not."
- World view: In a modern urban setting, there is a "high martial arts circle" (known to a few people), but mainstream society only recognizes law and technology, and ordinary people perceive "peerless masters" as "dangerous violent elements."
- Core meme: "Forward motivation + outrageous operation = reverse result". Every time Lin Fan "punishes evil and promotes good", he will be mistaken for a villain who "takes advantage of others" because his operation is too rough, does not explain, and leaves no evidence.
