supernatural universe fanfiction

Waking up in the supernatural world, our MC finds himself in the body of the oldest son of the Winchester family, William. So he taught to take advantage of his knowledge of the plot in order to survive, But as he later found out that will not be so simple. . Read how at first he uses his knowledge of future events to his advantage, and later he goes from a simple human to one of the strongest beings in his new world. He also has some powers from the beginning, as most reincarnated people do. . Guys, this is my first time trying to write a story, so please don't murder me in the comments. I want to see if I am able to write fanfics and not just read them. English is not my first language, and my writing in said language isn't as good as I would want it to be, so I'm going to use some sort of AI spelling corrector, but some mistakes might get through. I will try to post at least 1 ch a day . Maybe I won't be able to post daily all the time because of work, but I promise to finish this fic, because in my opinion, an unfinished story is worse than a poorly made one.
