The Transmigrator in Hogwarts

Song Ruilong was hit by a car on his way home from work and was reborn in England. His father was Chinese, but his mother was English. His father named him Song Ruilong. He grew up on Privet Drive and knew that a Dursley family lived nearby. He thought it was a coincidence, until an owl arrived when he was eleven. He looked at the letter the owl had brought, then at the Dursley family’s home nearby, and completely lost it. He had been planning to return to China and make a career for himself, but now you’re telling him this is the magical world? That would be one thing, except there’s no System either. He’ll have to transmigrate relying on himself. So, Hogwarts, here I come.
