Struggle at Genshin Impact

Supreme Leader Nanobana Kinako is struggling right now to her hardest challenge to her Genshin Impact experience which unable her to level up her adventure rank beyond 35. Her colleague suggested to continue the archon quest she can still play while it doesn't require higher adventure rank, then unlock Inazuma, for additional sources of artifacts to level up used artifacts. Her colleague suggested to level up her characters (4 at least) to Level 70, to prevent wasted character experience, she must ascend her characters before doing the ascension quest to move on.
