@bruh The attack on Glory City was a plan of the dark guild (and Demon Lord), but since Demon Lord went to the Draconic Ruins alongside MC, the dark guild doesn't have any real reason to attack Glory City anymore. MC also managed to convince several other people from the Nether Realm to keep tabs on both the Dark Guild and the Wugui family (who's also aware of Glory City) and neither of them could possibly deal with those experts. Power of Law is a completely different power that can be used alongside cultivation to make stronger attacks, but in the Draconic Ruins (where MC is) is a kinda insignificant power. Useful, helps, but it's not particularly relevant.
and yes, MC has understood 3 laws, Darkness, Light and Death
