Y'all I just noticed something, so Mori's emptiness kick purified the universe, right? And malice and everything was sucked in. Then how come the fairies did not die still? Xuanzang mentions that the fairies still exist, do they not have any malice in them? And why did he even need to leave earth if he can purify the Universe?
Also, these statements:
I don't think they should be taken literally, it's like me saying sleep and awake. There is no evidence he purified these dualities, at most it shows he governs over these dualities, which is more provable.
My explanation for why he didn't purify and fix the crack is that he wasn't aiming for the whole dimension, only what's inside the universe, and he left out space-time, which has the crack. It's a 3D feat.
But for the rest idk what to say.
If it cannot be explained and even my explanation cannot be applied to why he didn't fix the crack then it could be a possible downgrade on his hax for him.
