the first chapter of this fiction is unnecessary, an mc reincarnated in naruto universe as an Uchiha, he wanted to be superpowred by he ended up dying a dog death, even itachi despite how pacific did not feel sad for his death. from what I can see, you wanted your mc to have a sharingan. you was able to make him created it as hatsu ability. look, the first chapter of every story is important because its contents will make us decide if will continue reading the story or not. personally if I did not find other chapters, I was going to stop here. the first chapter must told us about the plot, a general idea of the story and especially the mc character. there is no need for the mc to be superpowred or genius, a hard working one with quiet serious personality when necessary is pretty good .
