Zhang Fan died, then was reborn. After more than thirty years of muddling through, he died again on the night his clan was wiped out. At the time, he was a Uchiha in his thirties, utterly ordinary, with mediocre strength: one tomoe and a rank of Genin. His wife had just died before his eyes, and he was terrified. The one who killed her was Uchiha Itachi. He would be next, and things were about to get bad. But in the next instant, he was killed. Dead. Then he came back to life and saw a monster in the spirit realm, a bloodthirsty monster. They touched for only a moment before he was cast out of the spirit realm, and just like that, he came back to life in spectacular fashion. His other self was a ghost! This cheat came at just the right time. He began making ghosts! Dead Uchiha, become ghosts and take your revenge!
From what I wrote before, you can probably tell that this book is not that good.
