What's the max level for hidden quests?

I don't even get those kinds of quests popping up at all lol

Slurp! It seems 'Jjeongi', who conquered the level 30 peak last time, is now exploring the end of a hidden quest, hmm! Hidden quests will continue to appear as you grow, so if you diligently pursue them, you'll soon clearly face the next stage. With a benevolent heart, I ask, what preparations are you making to surpass level 6?

All quests are random, so nobody knowsㅜ It's not like everyone gets the same ones just because others have a lotㅜ Some people don't get them at all.

Is it 60?

The hidden quest rewards are big and good haha

I'm not sure, but it's 21 or higher. Ah, looking at the comment above, it seems to be 60 or higher...

I wish I could get it too ㅠㅠㅠ

Wow.., I didn't have any hidden quests either.

I just finished 6 too and nothing else is showing up 😭 I think 6 is the end.
