Quests after NAADAM are beyond my level

[Risvertasashi]

I just completed the NAADAM at 66 and the next quest giver in House of Fierce says I need to be level 67 to accept that quest. Never ever been below the main quest line next quest level so this is new to me. I need 4 million points to get to 67. Where do I get those points? Non main line quests only give 100k so do I have to run approx 40 of those?

I would start with your daily roulettes. They give exp proportionate to your level. Which at your level, should be millions of exp.

You can also do sidequests if you prefer solo play.
