Lin Yuexin transmigrated into a Mary Sue harem novel.
The heroine came from a poor background, had poor aptitude, was reckless, and looked ordinary, yet a crowd of heaven's favored sons went crazy for her.
Unfortunately, Lin Yuexin had transmigrated as a supporting character. Her younger brother, her fiance, and her teacher would all become part of the heroine's harem in the future.
None of that was a big deal. The biggest problem was that the end-of-term competition was just around the corner. The original Lin Lexin was a genius zither cultivator from a family of musicians, but Lin Yuexin was a pureblood... tone-deaf.
She knew nothing about musical instruments and couldn't carry a tune.
Looking at the "Academy Standard Weapon Registration Form" in front of her, Lin Yuexin decisively filled in: Stringless zither. Please make the body out of the hardest material available. Thank you!
During the end-of-term competition, the audience stared in shock as the campus goddess Lin Lexin spun around the arena like a whirligig, swinging a stringless ancient zither and knocking every opponent flying, all the way into the finals.
Audience: Is... is this what a music cultivator does?
Lin Yuexin: Who says music cultivators can only play support? I'm the damage dealer!
Notes:
1. A future-set cultivation world.
2. There is a System, but it only takes up a very small part of the story.
Message: Who says a support character can't become a powerhouse damage dealer?
