Not contradicting you, just sincerely questioning. Why do you guys think that?
Do you think that being in a world abundant in Qi makes a cultivator's powers stronger?
It makes sense, but as far as I know, it would only affect cultivation speed and make Qi rechargeable without the need to kill or use Qi stones, the rest is pure speculation (without wanting to discredit various theories in the community).
And if so, would the increase in power be so great? Because, as I said, Tang Wei probably didn't have dao yet.
(As I said, just questioning. After all, I would love this to be the case, after all it would only make the MC more op.)
