Luochen traveled across time, came to the world of Harry Potter, and got the wizard supreme system. Although the system is relatively doggy, it is called a ruthless system if it is turned on and hung up. Leveling up is like drinking water, destroying Horcruxes in a few days, crushing Snape in half a year, and rivaling Dumbledore in a year.

When everyone found out that Voldemort had become a woman, and Lockhart had become a big devil, Hogsmeade was not the only one, and the Chinese language was popular all over the world...

Luo Chen has become a god, overlooking all living beings!

Smile lightly: All life in the world is in my palm. Who is more powerful than me in the world?

[Single female protagonist Hermione + mainly based on the movie plot, later plot changes + system]

Kevin traveled to the world of Harry Potter and grew up in an orphanage without ever coming into contact with magic. It was not until he was 11 years old that he finally received the admission letter to Hogwarts.

Reborn, he just wants to enjoy this magical journey, but as time goes by, he can't help but get caught up in it...

Snape: Kevin? Humph! Just a cocky brat with a bit of talent.

Dumbledore: Kevin is such a good boy who would go to great lengths to help his friends.

Voldemort: Kevin, this unethical and despicable villain! He has attacked me with a crowbar every time I die!
