I'm a Ghost Cultivator at Hogwarts

Zhang San, a direct disciple of Tianshi Mansion, was hit by the Avada Kedavra Curse on his first day studying at Hogwarts because he exposed Professor Quirrell's identity. The sect master rescued him all night long and taught ghost cultivating methods from a distance. Since then, Gryffindor has had a special student. When Voldemort came back, everyone in Hogwarts was prepared, but little did they know that this student from the Oriental Ghost Cultivator was already gearing up to give the Dark Lord a hard blow. Who says ghosts can't counterattack? Zhang San: Voldemort, eat my ghost claws!
