My Students Are My Power: Konoha's Secret Sensei

Transmigrated to the brutal Naruto world, Mu Yue is stuck as a weak chuunin teacher and, even worse, a disposable pawn in Danzo’s shadowy Root, cursed by a tongue seal. Survival depends on power, but he's starting at rock bottom. His only hope: the Teacher System! Every lesson taught, every student mentored, floods him with strength. When he cleverly recruits Uchiha Shisui, a genius with SS-potential, his power skyrockets. Shisui’s training doesn't just benefit himself—it duplicates for Mu Yue, turning a novice into a master overnight. Now, with Obito and Might Guy next on his list, Mu Yue isn’t just teaching ninjutsu. He's meticulously cultivating the future's greatest legends, all while quietly becoming Konoha’s true, hidden force, one student at a time.
