This story is not a time travel story about one person, but about ten friends traveling through time together. Moreover, the ten protagonists are all real-life friends of the author, and all have character prototypes.
So, if you took a group of friends and traveled to ancient times, under what circumstances would you recognize each other? How will you fight monsters together to level up and turn the world upside down?
Maybe a person traveling through the past is lonely, but we are never lonely. No matter you are a beautiful princess or a cold killer, whether you are a famous actress or a handsome scholar, it is a different life.
