Hokage, I, Iruka, Are Full of Peaches and Plums All over the World

Although the setting in Naruto is quite outrageous, it is the trouble caused by the Otsutsuki family, but looking at the development of the entire ninja world, there are almost countless people with cognitive problems. The protagonist came to the ninja world and did not know the plot of Naruto, but after seeing the pain caused by the war, he made up his mind to change everything! Setting: The protagonist is a powerful being who can travel through all the worlds. In the first world, he followed Zhang Zaixue, a great scholar from the Song Dynasty. His wish is the "Four Sentences of Hengqu", which the protagonist has been fighting for his whole life. I'm a new author, but I don't know how to write an introduction... If there are any shortcomings in the work, please give me some pointers, thank you! After all, this is my first work, and I hope it will be completed. I didn't have an outline when I first wrote it, so I'll update it as I see fit. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
