Hogwarts: I've acquired the Father System

Darren travels to the Harry Potter world and becomes Harry's twin brother.
Just as he was hesitating about whether to hide his identity for seven years, he obtained the Holy Father System.
By playing the role of the Holy Father, you can earn Holy Father Points, which can be used in the shop.
"Ding! Congratulations on obtaining Phoenix Carol!"
"Ding, congratulations on obtaining the Obscure."
"Ding! Congratulations on obtaining the Azure Dragon's Reverse Scale."

With the system's help, Darren, who plays the role of the Holy Father all the way, discovers that the path to godhood is surprisingly easy.
