your thinking of a different type of familial situation this is how it was back in the days for royalty you had many kids and you did not care about them unless they proved themselves in a way you approve of theyd marry you off against your will
@Ronald Westbeal Nah, he only has 3 children lol, and MC was his first male child. As far as I see Murim world are monogamous and has a quiet a degree of gender equality. This guy knows his wife wants to kill his son but he's like "I won't interfere", says a lot about the person.
