I Extract Everything at Hogwarts

[HP Fanfiction + Single or Multiple Female Protagonists + System + Snake Court + Behind the Scenes + Slow Heat]

[ps: Don’t join Ron’s party, I don’t like this character]

My name is Leggett Black.

After crossing over, I obtained a system....

It was also from this day that the world began to emit shrill screams.

Tang: Damn it, who stole my true energy!!!

Yu: "Ahhhhhhhhhhh!!! Oh my god!!!"

Jia Zhang: "Old Jia, please come back and take this thief away!!!"

In short, this is a story about exchanging everything in the Harry Potter world...
