(No CP + female protagonist's perspective + combat power ceiling + various single arrows)
Thousands of years ago, the only god bestowed supernatural powers on humans, fought off alien beasts, and then disappeared without a trace.
Thousands of years later, she made herself a vest of a D-class superpower, changed her name to "Chi Ruyi", and went to the Orillia Empire.
The plan is simple: go to the academy to fish, experience the fireworks of the world, have fun along the way, and see what the civilization you created back then has grown into.
She even set a small goal for herself - to stay in the empire for at least a year without exposing her identity or getting into trouble... Maybe?
(This article focuses on the perspective of the heroine looking for fun. The heroine is the strongest. Some other characters have emotional lines but the heroine does not. However, there are single-arrow heroines)
