Signing in Konoha for Eighteen Years

The author's writing and plot are good, and the butterfly effect of the plot is also handled very well, but there is one thing that needs to be reminded The level of Ninjutsu from D to S is the difficulty of learning. The higher the difficulty of learning Ninjutsu, the more powerful it will be. The power of Ninjutsu is determined by the amount of chakra input and proficiency. It's settled (except for some ninjutsu with fixed power, ranging from three-skin jutsu to flying thunder god). For example, in the Fourth Ninja World War, Madara's Hao Huo Mie was a B-level ninjutsu. The increased power of Ninjutsu may be achieved by Madara himself doing this). As a reader, I request the author to take a good look at the opinions and suggestions expressed by everyone in the comment area.

What the hell is this? There are a bunch of ads when you come in.

Come on, the book is okay, but it's a little less refreshing.
