Transmigrating into Harry Potter, he gains a system that allows him to grow stronger through learning. While young wizards are still struggling with the Levitation Charm, Rock has already mastered the entire Standard Spellbook. Hermione: "His notes are more complete than Mrs. Pince's!" The Weasley twins: "Great Rock! We call you the strongest!" Snape: "Potter! If your potions were even a tenth as good as his..." [Flicker] is maxed out to the Law level, a single [Radiant] Holy Light will crush any dissent. [Levitation] is maxed out to the Myth level, a wave of the hand [Universal Pull] will hold the stars in his palm.

Wait, is the system saying it has the talent for devouring and evolving? ...In the system's eyes, he gets more and more monstrous with age. In reality, he's only eighteen, his beast-taming career has just begun. (Elements of this book: System misalignment, text-based beast taming)
