you can make MC go to han jue's multiverse, top tier providence.Characters of that verse has BS power lvl, a dao creator can solo tensuraverse easily(in my opinion even a strong sage can) also at the end MC become omnipotent, omniscient, omnipresent... He created outside of blank meaning he created someting in nothingless outside of his verse... this achievement puts him near azathoth level according to your fic.
