All this need is a better MC to be better.

The story is killed by its own cheat, making it very predictable and boring. Skill progression does not matter because at the end of the day, that OP cheat saves everything. This could have been avoided if the author knew how to write "certain" restrictions to limit the cheat somehow, at least during the early chapters, but clearly the author have no plan in creating such a system.

Like the story. Don't like the MC.

Weak and boring mc. It's not ninjutsu that is mediocre, the MC is. The author tried to add many things, but it's full of crap.

I like it. Edit: Sometimes the story becomes annoying because it's too wordy and the author tries to create dramas in every game.

Ugh. The fact that he keeps getting injured that severely despite having that godly cheat is rather stupid.

Stupid mc.
