Do all protagonists have a protagonist aura? That's not necessarily true. At least the protagonist carries the aura of a villain; are all the protagonists hot-blooded and sexually involved in the harem? That's not necessarily true. At least the protagonist has always been single, and he is very bitter. Does the protagonist have a lot of artifacts and holy weapons wholesale? That's not necessarily true. At least the protagonist has been living a poor life, and he has no luck in encountering anything.
The miserable protagonist + the awesome time traveling crowd + the awesome reborn crowd = infinite peak
