Sorry if you think the title is confusing, I just don't know how to title this better. I'm looking for novels or mangas where the MC is OP, or has a system that makes them OP, but the catch is, it's their own power, not something god given or something that existed before they were born. Kinda like: - Tensei Shitara Slime Datta Ken (MC develops the skills himself) - Solo Leveling (MC steals the system from its creator and later even deletes it to gain more power) - The Gamer (It's his own power, it could be anything, but it's a system cause of his gaming addiction) - Arifureta Shokugyou de Sekai Saikyou (MC devours hundreds of monsters for their power and uses a super healing item to keep himself alive while doing so) - Mondaiji-tachi ga Isekai kara Kuru Sou Desu yo? (One doesn't exactly fit here, but of the other two, one is born with a cheat, the other is born OP) - Kumo Desu ga, Nani ka? (MC transcends the system) If a god can give you any kind of cheat, they can just as easily take it away, but it's a different story if it's your own power and not a gift from someone else. Please no xianxia and thank you in advance.
Maybe: Re:Monster (MC gains skill by eating, including cannibalism) The New Gate, Overlord, Skeleton Knight in Another World & Pupil of the Wiseman (they got/uses the skills they've gained from their in-game characters) Death March (+/- similar to Tensura & Kumo-chan) Hachinan tte, Sore wa Nai Deshou! & Magi's Grandson (trained by others, but the rest are depends on their own knowledge) Goshujin-sama to Yuku Isekai Survival! (OK, it's isekai, but MC didn't met any God(s) & just got a system similar to minecraft, except he could add something if he thought about it) Tsukimichi (the only skill he got is language, the rest are his own work/power) Isekai de Cheat Skill wo Te ni Shita Ore wa, Genjitsu Sekai wo mo Musou Suru ~Level Up wa Jinsei wo Kaeta~ (inherited his grandpa's house which somehow connected to otherworld)
