So I read up a bit about the lore of the last know cultivation level (the creation realm) and to attain that realm is pretty fûcking crazy.
Spoiler!
So to attain that realm one would have to be seen as a threat to do itself and when that happens your transportes to the realm of cause filled with everyone from other worlds who's also attained that level of strength and there's only 2 ways to escape that realm either by killing a large number of beings in that realm but since that place is literally filled with the strongest beings killing them is way to challenging and if you did manage that you'd just get ganged up on by other residents the second way is for the people of your original world to remember you and want you back in that world (dao starts to wipe your existence from everyone's memories) so basically to escape the chaos realm you'd have to rely on the power of faith
I like that I can stalk people with this update
