Hogwarts Nemesis

This is a magical world. Hogwarts, a magic school that nurtures young wizards. Lyon Sirius Potter is eleven years old, just in time to enter Hogwarts, and he has attracted much attention. Forty years ago, Leon's grandfather led the crowd to defeat the dark forces led by Voldemort and protected the entire Hogwarts and the entire wizarding world. His name was Harry Potter. He is an immortal legend! The legendary secret code, the book of life and death that can predict the future, and the magical wand that even Muggles can use to perform magic, are gradually eroding people's minds. Who is the initiator? Behind all of this, an undercurrent surges, pointing all fingers at the Order of the Phoenix. The Ministry of Magic continuously attacks and suppresses it. I don't know who is fueling the fire, making the wizarding world public in the world where Muggles live. Everyone is in danger. Magic is so magical, but if it is used in a bad way, it will be bad... People are selfish, and they always try to destroy the dangers of ignorance first. As a result, a war filled with smoke is about to break out between the Muggle world and the magical world... (Warm reminder: This is a story about the grandson of Harry Potter. Of course, the iron triangle of Harry, Ron, and Hermione will have a major role. In addition, I personally like Albus Dumbledore very much, so some plot adjustments will be made here. The principal of Hogwarts School of Witchcraft and Wizardry will still be Albus Dumbledore)
