Naruto: Start with Devouring

Anti-routine + Darkening Kakashi + Decisive Killing + Harem ((Those who mind, please enter with caution)) Lin Xiaochong was originally a power training anchor of the Naruto mobile game. He accidentally traveled to the Naruto world and awakened the Devouring System! As long as you swallow it, you can obtain all the ninjutsu and chakra that the ninja learned during his lifetime! You can also obtain heaven-defying talents by solving emergencies. Lin Xiaochong stopped Obito who was rescuing Kakashi and killed the old Madara who was surviving on a heretic demon. Lin Xiaochong thought that he was perfect, but he never thought that Madara would activate Izanagi again before he died, and Kakashi did not die. Instead, he was rescued by Madara and underwent deep brainwashing. Completely despairing of Konoha. This time the Hokage turned around and was more dramatic than before, but for Lin Xiaochong, it was just a stumbling block on his way to dominate the ninja world! !
