Reborn in Hogwarts and Become Invincible

In his previous life, William was an ordinary person who died in an earthquake. In this life, he thought he could only go to an ordinary school and be an ordinary nobody. Unexpectedly, I found myself in the world of Harry Potter. My ancestors were good friends with the four founders of Hogwarts. I also accidentally obtained the magic power of the four founders and a wand with all the magic power of my ancestors. So I used the system and powerful magic power to dominate the wizarding world and started my journey to be the strongest in the world. Dumbledore: "Sir James is too scary! Don't mess with him!" Grindelwald: "James! How dare you hurt my Al! Oh, forget it, don't settle the score with him, I can't beat him either." Harry Potter: "His Royal Highness James is the real savior! What use does this world have for me?!" Hermione: "His Royal Highness James knows so much knowledge! I admire him so much!" … This novel and its characters are purely fictitious.
