Honkai Impact: Feather of Space and Time

(Single heroine Kiana + a little system + a little knife + slow heat) Have you ever thought about people from previous civilizations entering modern civilization? New plot, new relationship, new map, new knife(?) —— Endless ocean, towering giant trees. [Creation] and [Destruction] [Change] and [Redemption] [Feather] is born from giant trees and oceans, and falls from them. The world has already changed! In short, a new world has begun. So, Maple Feather. Can you change the course of your destiny? (It contains a lot of private settings and may not have much to do with the plot of the original work. This is the author's first book. The writing is not good in the early stage, but it should improve in the later stage.)
