This world is composed of five elements: metal, wood, water, fire, and earth.
I thought it was a normal day, but when I woke up, I was already in the Five Elements Realm.
When I thought that as long as I kept fighting and getting stronger, the mystery would be solved, what greeted me was confusion.
When I was about to give up again, I heard from behind:
"Thank you hero!"
"Great hero!"
"Hero!"
The heroic dream of my youth was awakened.
(Not invincible + not cool writing + single female protagonist + humor)
