Blazing eyes (Uchiha OCSI)

Being reborn in a world full of monsters, the young Uchiha realizes that he would need overwhelming skill to survive. But he doesn't have much time, as he is only older than Itachi by one year. How will Kaen Uchiha live and survive in a world where he is in constant danger? Not a gamer system, no wishes, just old plain Sharingan that is all you need. Check Fanfiction(dot)net for the rest of the chapters and other stories. It is the same name. (I am the original author, just transitioning to Webnovel too.)
