Fine

you're killing the characters in the novel you created
build 1 MC too op, making the characters have no place in the story.
All I see is a repeating story:mc goes to another place, solves problems and increases his strength horribly while there is no motivation for mc to grow + a certain girl in position falls in love and mc with the spirit of the old man going to teach people about the way of life
The stories that unfold are excruciatingly boring: a 12-year-old boy solves the problems of countries while out of the house for less than a year.
There are many ways to develop the character but maybe you run out of ideas and the work is a mess
I pause at chapter 244
