Have you read The S Class That I Raised?

Yes all the old ones before 2025 I’ve read them all.

How about these? Not really similar but weak to strong:

Some get strong too quickly though

loser to strongest mc manwha:

-star fostered swordsmaster
-nano machine
-the lazy prince becomes a genius
-reaper of the drifting moon

isekai/regression manwha:

-revenge of the iron blooded sword hound
-pick me up
-magic academy's genius blinker
-return to player
-regressor instruction

you wont really be able to find manwha similar to orv but these are all rly good :)
