HP: I Heard You Can Send Messages to the Dead

[HP sub-era + original heroine + golden finger] During the Easter holiday, Noran squatted on the street selling cookies he made while flipping through the golden finger he brought from his previous life - the Book of the Dead. There are many magical skills in this book, which have the ability to change the world, but she needs to collect enough points to learn them. If she learns them all, she can become the legendary undead god! It's just that the simplest skill here requires ten points, not to mention the resurrection of the dead technique which requires ten thousand points. And the only way she can get points is to be a messenger and help people deliver letters. She is a bit special as a messenger. She can not only deliver messages to the living, but also to the dead. But she was too young to believe her words. Until she met a man with a scar on his head, which started her splendid life in the magical world. ———— "Can't I really use people as puppets?" Noran asked seriously. Black magic? Orphanage? Harmful? Dumbledore's crisis radar went off like crazy. Harry nervously handed the letter to his parents into Noran's hands, but he didn't expect to receive a reply. Snape took Lily's reply to him and hid in the dark room. Harry looked at Noran who was huddled with Malfoy, and asked quietly: "Isn't your best friend me? Book of the Dead: See that soul fragment? Just conquer him and you'll get a thousand points. Noran: Braised eggs! You come out! Let me show you what real black magic is! Ps: The heroine comes from another world, has little legal awareness and weak moral values.
