math is not my strong
I totally agree with you reader, in the first chapters, do not pay so much attention to the details, that will be fixed in the future
That's the point, the mc's strength is his martial art, he uses ninjutsu and genjutsu only as a means of support, that's why he didn't develop it, but don't worry reader, that will change in the future.
Spoiler in the next war, which is coming most of Oc will die.
maybe in the future this question will be clarified
I understand the confusion lol
you have a valid point, but you should remember the scene where Shorohige almost killed Kurohoge if he didn't have so many injuries.... and you can't compare my protagonist to Thatch, who I'm sure Kurohige attacked him by surprise
one of the commanders is the one who will receive the manual in the next chapters
