One Piece Fanfiction: The Straw Hat Crew's Healing Days

I just love the Straw Hat crew's vibe so much that I wanted to try writing about them. Please be kind, please be kind. I'm new to writing.

GB pairing, with Luffy as the love interest, though the romance probably won't be very prominent. My writing is terrible. The characters are very out of character, so please bear with me.

The heroine, Qiu Ming, had just finished her college entrance exams in her first life and hadn't even had a chance to enjoy her vacation when she was transported into an infinite-flow dungeon. Later, she and the System destroyed each other, but just before she died, she was sold to another world's consciousness: the Heavenly Dao. Qiu Ming began cultivating immortality, but just as she was about to break through, the Heavenly Dao threatened her into using her soul to suppress a world-destroying demon. She was imprisoned for three thousand years before finally dying, only to be reincarnated in the world of One Piece, like a nesting doll. But there, she found salvation.

Don't worry, don't worry. The heroine's first two lives will only be briefly mentioned. The focus is on One Piece.
