Naruto: My Jutsu Have Gone Dark

When Mu Feng wakes up, he discovers that he has transmigrated to the Naruto world and become a member of the Uchiha Clan. He's in the same class as Obito and Kakashi, and Mu Feng feels enormous pressure. Fortunately, he has bound himself to a corruption System. The ninjutsu, taijutsu, and Kekkei Genkai he learns can suddenly become corrupted and grow stronger. [Ding! Your Clone Technique thinks you're too weak, so it has become corrupted. You have obtained Perfect Clone Technique!] [Ding! Your chakra feels insulted and is turning into 'chakra tons'!] [Ding! Your bloodline feels looked down upon, so it has become corrupted. You have awakened the Three-Tomoe Sharingan.] ... Shinra Tensei, Chibaku Tensei, Limbo... Once Mu Feng learns these techniques, the Shinobi World gains a supreme powerhouse.
