Harry Potter: Dimensional Wizard

Edward was reincarnated into the world of Harry Potter, an act which excites him giving the fact that this was one of his favorite books. So, he embarks on the path of wizardry in the hope of discovering the way it works, the laws or theories that govern it; he wanted to find its essence. He tries to find the answer to questions like What is the soul. Why can wizards use magic, while muggles cannot? Do bloodlines truly exist? And if so, what use is it to wizards? Could it be the reason that some wizards are born with exceptional talents like Parselmouth or Metamorphmagus? When Edward finally uncovers the answers to these questions he pondered on, he suddenly thought to himself: "Since the world of Harry Potter is real, what about all the other anime, movies, games, and books that I read from my past life? And if they are indeed real, how I can I get there?" This story is an Infinite Stream novel where the mc travels through different anime and movie worlds acquiring various magical abilities and knowledge to become a supreme wizard that stands on the top of countless dimensions and universes. Warnings: The MC will spend a great deal of time in the Harry Potter World before going to other worlds. I have not decided whether the [Curse Child] is canon or not. I do not care what JK Rowling said. This is a pseudo-science explanation of magic, so take it with a grain of salt. I am an amateur writer with not-so-good grammar, so any constructive criticism is appreciated. This is a wish-fulfillment and Gary Stu-type novel so read at your convenience. If this is not your kind of thing, then move along and do not complain about it later. Although this fanfic will be a Harem, the mc will not have a thousand women. Most likely, I will write so that he has a certain relationship with some female characters, then he will leave her in her own universe. Only a few will follow him in his journey. Also, a few men will be in his group. THIS IS NOT A YAOI. Disclaimer: All the characters--except the one created by me--belong to JK Rowling.
