The Hokage Teaches, the Time Is Wrong, Right?

Drop! It is detected that the host is over six years old, successfully enrolled in school, and meets the training standards, and the strongest Hokage training system is activated. But why did the system determine that I was only six years old? Some of the tasks posted are also weird. I am a teacher at a ninja school. Is it really appropriate to do these tasks? Even if I jump from here, I won't do it! When I traveled to the world of Naruto, I thought I was a three-dimensional time traveler, but at the end of the day I was just an ordinary chuunin. In order to survive until the end, I chose to teach at the Konoha Ninja School until the training system for the strongest Hokage was opened, and the gears of fate began to turn, becoming the most powerful person in the world of ninjas.
