HP: the Witch and Her Professor

[1V1 double heroine + Hogwarts worldview + vicious and mean Professor Iceberg x paranoid genius girl in a straight-ball age] It is not the original timeline, and the protagonist has nothing to do with the protagonist of the original book. In the wizarding world of the eighteenth century, the undercurrent never subsided. In the name of creating gods, the Wall family plundered talents, refined blood, and laid out shocking conspiracies spanning generations. As the only successor of the time bloodline, Celine Russell entered Hogwarts alone. She doesn't do it for glory or belonging, she just wants to find out the truth behind her parents' disappearance and escape from the fate of being manipulated by others. Cassandra Wall, Head of Slytherin, is a defector from the family and the master of forbidden potions. She had been dormant for many years, covered in sins and scars, just waiting for the arrival of one person. One is the core of time, and the other is the key to refining medicine. They were the two most perfect chess pieces in the plan, but under the lights of Hogwarts, they became each other's only salvation. Blue eyes meet amber, fate touches the soul. They decided to change their destiny against nature and tear the chessboard to pieces.
