Makes sense, transmigrators who take over an existing body usually are because the original host died... But how did she know that? She's only a time traveler in a world that doesn't have transmigration stories...
@wilddeath I can't say I remember anymore, cba to go back to the start to check... But isn't just her future self that dies? Why would her current timeline self had died when she traveled back in time, when her original timeline self didn't die at that point?
