Konoha teaches, then stands in the sky

Mu Yue traveled to the world of Naruto and became an ordinary Chunin teacher at Konoha Ninja School and a member of the Root organization.
Fortunately, after awakening the teacher system, you can become stronger by teaching.
In order not to become Danzo's consumables, Mu Yue worked hard to teach and increase her strength.
"Complete the teaching rated A for the first time and receive the reward - mastery of fire attribute chakra properties change."
"Under your guidance, Uchiha Shisui has practiced hard and his overall strength has greatly improved. He has been rewarded - the Sage Body!"
Under Mu Yue's guidance, Shisui understood that the village's enemies might not necessarily be other big countries, but might also be within the village, and that those who could talk about the Will of Fire very well might not necessarily act in accordance with it.
Obito got rid of the title of the last in the ninja school, and Might Guy became a master of physical skills earlier...
