I am just an ordinary college student. If not wanting to fall in love is a special case, then I am only different in this way. I just wanted to hide for a while, so I actually joined the time-traveling army! ! ! Forget it, survive first is the most important thing. But could I really endure life without sanitary napkins and flush toilets? Can I forget my modern friends and classmates and those joys? It's so imaginative and thoughtful, I want to give you a real feeling.
