Comprehensive Comic: the System Takes Me to Rescue, and It's Hard to Calm Down

(Part of the plot is OOC+privately designed) Lin Qiqi watched Ace being punched through the heart by Akainu Demon Slayer: Demon Slayer becomes Hashira Slayer: Kimetsu no Yaiba The sacrifices of Sirius, Regulus, Severus and the Weasley twins Lin Qiqi thought: It would be great if she could go to their world to save them. A white light flashed, and Lin Qiqi's wish came true. Ps: Comprehensive story, the heroine may have CP, the main world includes One Piece, Kimetsu no Yaiba, and Harry Potter, the heroine has a golden finger (system), and all skills are obtained by completing tasks (special episode of Ming Ke's rescue of the police academy team) This is my first time writing an article. My writing style is not very good. Please forgive me.
