Recommendations Novel where the protagonist is consistently low-key

I'd love to see some low-key MCs who only show their powers if the situations demand and don't hide their abilities/identities just for the first few arcs in the beginning.

Demon’s Diary, Martial King’s Retired Life, Tempered Immortal, My Senior Brother is Too Steady and A Record of a Mortal’s Journey to Immortality are really fun.

Thanks!

 

Hero? I’ve Long Stopped Being One (Hero's Return)

 

Main Character Hides His Strength is good I think.

 

1. Rebirth of The Heavenly Demon (Jang Young Hun)
2. Tempered Immortal
3. Assassin’s Chronicle

 

I really want to re-pickup this one but the reviews seem harsh towards the series' ending. Are the final arcs that bad?

 

Dungeon Defense

 

Sign In Buddha Palm

 

It's eh. I can't really describe it.
