Naruto: My Ninjutsu Has a Life of Its Own

In Konoha's 51st year, during the Nine-Tails' attack, Xinye is reborn beneath a heap of rubble. The good news: he awakened a System. The bad news: failing to complete its missions costs him his life. Even worse, he only has a few days left to live. And there's more bad news: he can't use the five nature transformations. In that case, he'll just do without them. There are other options, after all. Gradually, he discovers that his ninjutsu is different: his techniques are alive. Tobirama Senju created forbidden techniques. I create ninja beasts. Madara Uchiha: A little rubble like that? One illusion of mine would be enough. Xinye: Anti-Uchiha Slime, activate.
