Instead of trying to do it you can just continue after chapter 40 on another account and when you are fit and time you can slowly copy chapters 1-40.

plot

sasuke went to the academy at 6 years old (this is in peacetime), the massacre takes place a year after that where he is 7 years old. In other words, the mc should have started the gym at least a year ago. You clearly didn't research it correctly.

talia's betrayal happens in canon, that i remember she must be pregnant with batman... and that this son in the future would become the 5th robin.

calm down man... the author has his own life, at least he's warning you.
