HP: god of potions

This is the story of a soul reincarnated into the body of a first-year student attending Hogwarts, without any knowledge of the world(s) he's in. Follow his sleepless journey across the Harry Potter universe, where his single goal is to gather materials and become a god through his potion system. However, this isn't just any ordinary universe—it's an amalgamation of many. Join Gray Knight as he embarks on his quest to create the perfect potion, uncover who disrupted what should have been an easy journey, and evade the hunter chasing him. --- Warning! English isn't my first or second language, but I'll try to write something you can read and understand. This story revolves around potion-making and the search for ingredients. As a wise dwarf once said, alchemy is about gathering materials, so there will be monster fights and hunting. In fact, if you have an ingredient Gray needs, you're done for! As for romance, let me be honest—I don't know the Harry Potter universe very well. I've watched all the movies and am rewatching them while writing this fanfic, but I won't know obscure characters like Tonks. Who the hell is Tonks? I still don’t know! This makes romance tricky, but I'll try to find the most beautiful girl in this or other universes for Gray. Still, Gray’s first love will always be his gold coins. NO HAREM.
