Naruto: The Darkness Within, You Call That Justice?

Transmigrated into the world of Hokage, with no System, no harem, and the ability to use ninjutsu without limit. He refuses to grovel before Konoha, and the story is logical, not brainless. Jiang Ling has been in the world of Hokage for over twenty years. Born during the Third Great Ninja War, he became an orphan at a young age. Talk about bad luck! He thought he would get a System that would let him punch Hashirama and kick Madara, but he never even heard a mechanical voice. Fortunately, when Heaven closes one door, it opens a window. This body can use ninjutsu without consuming chakra, but Jiang Ling can only use the techniques this body would normally be capable of. He cannot unleash a sea of flames like Lord Madara and is limited to low-level ninjutsu. Still, his mastery of those basic techniques eventually earned him a reputation as a genius, though he was overshadowed by all the overpowered characters in the village. That was a good thing, too. His only advantage here was knowing the story and having received nine years of compulsory education. He could not let his actions change the future, so Jiang Ling kept a low profile until he finally lived to see the arrival of the two chosen ones.
