Naruto : Ninja school teacher, I can become stronger by teaching

Mu Yue transmigrated to the world of Naruto, becoming an ordinary Chunin teacher at the Konoha Ninja Academy and a member of the Root organization.



Luckily, he awakened the Teacher System, allowing him to grow stronger by teaching.



To avoid becoming Danzo's expendable asset, Mu Yue diligently taught to increase his strength.



"First time completing an A-rated teaching session. Reward: Mastery of Fire Release Chakra Nature Transformation."



"Under your guidance, Uchiha Shisui has diligently trained, significantly improving his overall strength. Reward: Sage Body!"



Under Mu Yue's tutelage, Shisui realized that the village's enemies weren't necessarily other great nations; they could also be within the village itself. Those who spoke eloquently of the Will of Fire didn't always act according to it.



Obito shed his "dead last" title early on at the Ninja Academy, and Might Guy became a taijutsu master even sooner...
