My Little Pony: I Control Time and Space

[My Little Pony fanfic + some original characters + original CP + single female protagonist and single male protagonist + time travel + system + time and space] (If you don't like many original characters, you can skip it~) By accident, a girl named Yeyue traveled to the world of My Little Pony and activated a system. By some mistake, she became Twilight's younger sister and attended school. So Yeyue took things as they came and started to get involved in the plot, but tried hard not to let the plot deviate. Yeyue gradually discovered that she was extremely skilled in the magic of time and space. As the plot progressed, Yeyue slowly discovered that some characters who shouldn't have suddenly appeared around her. First, a divine messenger, Yu Nian, appeared in the Eternal Free Forest, and then a unicorn, Ling Xin, followed by several unfamiliar names. Perhaps, this is not the original My Little Pony world, but its parallel world. And among them, Yeyue's original status seems to be not low. Yeyue, at this moment, embarked on the path of finding her original life... —— "Everything in the world has a meaning for its existence. Since it already exists, it means it should exist and find the meaning of its existence in the world." "Time and space are like this, abstract and fuzzy, invisible and elusive; but it is also very magical and is the first law of all worlds." ———— There is absolutely no knife in this book!
