Sorry, looks like I've been really inattentive with reading. *Sigh*

Suggestion: Wouldn't it be a good idea for the protagonist and his companions to train under the influence of Gravity? Also using Heal Pulse, so they could cycle: train to exhaustion under Gravity, use Heal Pulse, and go back to training again.

Just one question: Is there any reason why the protagonist is not using Teleport as a means of locomotion?

Maybe I'm just stupid, never mind. It's been over 220 chapters and I haven't learned, so I've given up. 😂😂

So it's only relevant to have everything in S (or SS or SSS) when going to the next stage ((High) Silver to (Low) Gold, for example) or not?
