Harry Potter: The Black from the East

Suppose the heroine has Xu Yourong's identity from Ze Tian Ji and is named heir by Empress Tianhai, while all the other Ze Tian Ji settings remain unchanged. Regulus Arcturus Black fell in love with the third daughter of the Tianhai family, Tianhai Jinhua, and they had a daughter. Before the child was born, Tianhai Jinhua returned to the East, and Regulus became an Inferius. The heroine is the same age as Harry Potter. Fourteen years later, when Tianhai Jinhua is gravely ill, she sends the heroine to the West to find Regulus. Timeline: Just as Sirius is preparing to hand over the Black family home to the Order of the Phoenix as a headquarters. Slytherin mindset, Dumbledore conspiracy theories, pro-Black. Don't read if you dislike this. Whatever you argue, you're right. The heroine's values don't represent the author's. Writing for love, with elementary-school-level prose.
