Basically the main characters original world got turned back in time (killing the whole planet besides our mc ) by the empress using a the second version of the Arium which our Mc has now the mc had to go to the current world she’s at now in order to put a stop to the empress(which she did) and fully learn the powers of the arium ( her immortal abilities and past manifesting abilities ) which she’s learning how to do now there’s a lot more stuff I just summed it up to her main mission of the story but if u want and in depth explanation I can try to do that
I’m not gonna pretend I know or ever knew anything about the plot of this manhwa
