He Wushan knew of He Xiu's obsession, but he never tried to offer advice, or even address it.
The style of Famous Sword Villa has always been straightforward and brutal. They don't participate in cunning schemes and conspiracies. In all matters, they let the swords in their hands do the talking.
The same goes for He Wushan's method of teaching his disciples.
In his mind, if He Xiu was unable to erase his obsession, thereby affecting his cultivation, it illustrated that his training was insufficient. What right did someone, who couldn't even control their own heart, have to be the family head of the He Family?
So, even though He Xiu was still young, if he was unable to control his emotions in the future, even if he was He Wushan's own grandson, He Wushan wouldn't hesitate to cultivate another disciple of the He Family into the family head.
