This is pretty good, in a comedic sort of way. I can't bring myself to think of this seriously though, there's too many ridiculous things happening just in the first chapter, enough to get an Isekai bingo.
1. MC is stupid OP, unable to comprehend own strength
2. MC's 'cheat' ability comes from nowhere, makes no logical sense
3. Everyone depends on MC for everything, MC thinks nothing of it
4. Magic status card that's only purpose is to show how OP MC is
5. Muh peaceful lifestyle
6. Princess waifu literally falls into his arms without reason/foreshadowing
7. Trusted advisor betrayal
8. Glasses guy is evil
9. Treaty w/ demonkind broken by demon subordinate, not demon king
10. etc
