Just recommend me a novel where the MC's goal and the reason to why he wants strength is to surpass or defeat someone (it's pretty much the main plot). Something like Paradise of Demonic Gods (I dropped this) or Possessing Nothing (still no updates?).
Charm of Soul Pets- The Mc wants to surpass and prove himself for the soul per who abandons him. https://www.novelupdates.com/series/the-charm-of-soul-pets/
Coiling Dragon Stellar Transformations Emperor of The Cosmos Everyone Else is a Returnee Seoul Stations Necromancer Sovereign of Judgement Against The God's Tales of Demons and God's (shit but it fits) Main Character Hides His Strength These are quite broad and loose parameters. Alot of novels fit into this by default.

I've said it and I'll say it again. Heavenly Jewel Change 1. For his hometown, Spoiler He will defeat the invaders Also for revenge plot 2. For each of his harem, Spoiler He will defeat father in laws and love rivals 3. And to not be defeated by higher powers who is jealous of his strength and want to take control of MC. Without the main 2 reason, he'll never strive to seek strength even with his OP blessing. And for the 3rd he will simply run away but can't because 1 n 2.
Kuro no Maou MC gets transported to a dif. world becomes part of cruel Human Experiments, where he gets his Power. His main reason to get stonger is to beat the saints, powerfull OP enemys granted the power of the white god. This Novel is speecial in that regard, bec he starts weak and has no real plotarmor. There are multiple dead sidecharacters who have unergone characte developement, and this lack of plotamor for the good guys makes the story unpredictable and super interesting. Meanwhile kurono and his allys are compared to the 'normal' Mortals extremely powerfull but still has no chance against the saints. If you are looking for something more simple Sovereign of Judgement
