I, the Devil Behind Hogwarts

Reborn through the world of Harry Potter, Tom Riddle awakens the heaven-defying [Behind the Scenes Demon King Development System]! His goal is just to study hard, but the system always releases some weird tasks, and the rewards are even more incredible! Bite! You successfully fished the legendary "Mermaid's Tears" at the bottom of the black lake, gained +500 charm points, and unlocked the hidden talent "Charming Halo"! [Ding! You "accidentally" blew up Professor Snape's cauldron in Potions class and received "Chaos Points +1000", and the reward: Transfiguration Mastery (Master Level)! [Ding! You successfully made Voldemort kneel down and beg for mercy, cry out "Boss, let go of my Horcrux!", And obtain "The Dark Lord's Deterrence +99999"! The system automatically settles: You have become the recognized "Devil Behind the Scenes" in the magic world! Tom looked confused: "I just wanted to be a good student, so how did I become the big devil behind the scenes who gave Dumbledore a headache, broke Snape's defenses, and made Voldemort tremble?!" He looked at the crazy soaring [Influence], [Fear Value], and [Loyalty] on the system panel... This world is really hopeless!
