why bother? This is skeleton wizard we're talking about. Dude can't write an original plot to save his limp dixk.
Super talented MC in either science, math, engineering. Combat talent is a must. To offset this, the guy's EQ must be retarded to the point where you wonder if his complete lack of common sense is contagious. This can come in two flavours, either he is so out of touch because he never grew up around people or he's a dimensional migrant.
There will be some sort of dumb ass online game or pvp matches where the originally shit MC will go in with a secret identity. There will be hype.
There will be so much hype.
Even though you realize how childish and silly this game actually is if you take a step back and look at it objectively.
The identity reveal will be dragged out as much as humanly possible, vbest if it's more than 900 chapters in, meanwhile the MC gets "underestimated" and treated like "trash" the whole time.
Outside of the game, which should make up the majority, about 80%, for the first half Of the novel, the MC will have another goal. Usually something that's not directly relevant to his main skill set. For example, tempest of stellar war, MC is super science and math genius, but his goal is mechanics warrior. Obviously his talent for both is sky high.
The only good things I can say about his novel is that at least there are little to no idiot young masters or unreasonably retarded clans with Titanic level egos who flip out and try to commit murder just because you said no to them. That and the romance, generally not harem. But the women around him are developed to some extent, plus the MCs are usually straight arrow typeS who devote their hearts to only one girl. With battle frenzy being the only exception so far I think.
