Douluo Continent I, Transmigration

I want a story where the protagonist transmigrates into the Seven Treasure Glazed Tile Clan as Rongrong's older sister. Her martial spirit should be a fan, a sword, or something similar, with offensive power that can also protect people. Dual martial spirits are fine. No System. She should join the main cast, not steal Tang San's opportunities, break up no canon couples, and have no male lead.
