From a Matriarchal World Back to Harry Potter

This is the sequel to "When V Transmigrated into a Matriarchal World"~ After living out their natural lives in a matriarchal world, V and the professor transmigrate back to the eve of the story's beginning. Will the professor, now the empress of the Xingchen Kingdom, lead Slytherin to ruin? And what choice will V, the professor's partner, make? The pairing is SSLV. The roles cannot be reversed or changed~ The dynamic is an overbearing emperor as the dominant partner VS a wife-like demon king as the submissive partner~ P.S. Although this is a sequel, you can read it without having read the first story. If you'd like to read the earlier story, just visit my author page. It's a short story of under 20,000 characters, so you can finish it quickly~ P.P.S. I chose to start this story today because it's Buddha's birthday, though I don't believe in Buddhism...
