Marrying 10 female from the island family was absolutely unnecessary like wtf could have married one or two if you want to keep alliance but no 10 at one point … and besides he didn’t need the family to be on good terms with him since anyway the islander are sort of slave … if he cared he wouldn’t have left but rather developed the family so Yh anyway he just become a horny dog comes out and married a twin so 12 wife for nothing …
Not to mention all this kid born to him end up Dying sooner or later cause of their low qualifications
Mc could have waited and married some girl with holy body and had kid with high talent that could accompany him and create immortal type shir anyway trash
