If you're looking to casually find a breakthrough and then use it to eradicate the other party completely, then you shouldn't delude yourself into thinking that this tactic would work against a family's inheritance clan.
Because it simply won't be effective.
Just like the time when Wang Chao was fighting a life-death struggle with the Heroes Association, rumors had already circulated in the rivers and lakes that the big hand behind the Heroes Association might just be the Kojima Clan, a family's inheritance clan.
And later, when Wang Chao was battling wits and bravery with the Heroes Association, he didn't hold back at all and fought with deadly intent.
At first, he thought that if he pushed too hard, the Kojima Clan might not be able to restrain themselves and would come out to confront Wang Chao on behalf of the Heroes Association, but in the end, what happened? Nothing at all.
