HP: I Analyzed Magic Circuits at Hogwarts

Aiden always thought that he was just an ordinary kid with an extraordinary memory. Until he was eleven years old, he encountered an out-of-control magical toy in Diagon Alley and saw something that others could not see. Every spell, every magic item, and every broken barrier is not a result in his eyes, but a structure. He could see how magic worked, and he could see where they were broken. So here comes the problem. When the stairs in Hogwarts would suddenly become misaligned, armor would run wild for no reason at night, and cracks began to appear in the defensive circle behind the restricted area on the fourth floor, others thought it was an accident, but Aiden knew that there was a magic system buried in this castle that was far older and more dangerous than the textbooks. Starting from repairing a broken rune, to improving spells, dismantling alchemical structures, and rebuilding ancient circuits. While Harry was still facing the shadow left by Voldemort, Aiden was already standing on another dark line in Hogwarts. Some people want to use ancient magic to restore order. Someone wants to turn Hogwarts into a weapon of war. And he just wanted to figure out one thing first: What did the four founders hide in this castle back then?
