Comments of chapter undefined of A Ninja In The Galaxy

This scene like scenario is in most of the system fiction like MC getting a little strong and infiltrating an enemy base see's a girl about to be r**** getting his blood boil and then massacring every bandit or pirates in the base then the girl is like I lost hope for me but then I saw him and he saved me so I am grateful to him for life then the mc literally just trains her his technique. I mean c'mon keep your techniques to yourself just tell the girl to join Jedi order if she wants to become strong.
