LostWizard
Why didn't he kill Rimuru? At least MC could have become stronger with his spirit and energy. and fewer rivals for him. The author wrote an illogical plot again.
ahahah. family atmosphere hahahha. author, you really don't know the mc you are writing for. you are really good at writing illogical novels.
LostWizard:lets look at it another way. Rimuru never seeks confrontation if he can avoid it and even if zerr'on for some reason decided he wanted to kill him, it would definitely not be good for the family atmosphere if he kill one of his daughters friends
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.
