This is precisely why the Beast Soul Valley is so crucial to the Soul Charm Sect, and this is one of the reasons. Without the demon beasts within the Beast Soul Valley, the disciples of the Soul Charm Sect would lose a place for training. The rules for each inner sect examination are actually quite simple, which is to hunt ten demon beasts equivalent to the Jindan level.
As for how to slay them, there are no specific regulations. As long as you have the ability to have someone deliver the killed demon core to you, you can thereby become an inner sect disciple.
This rule is actually quite interesting because, in this way, it is truly unfair to those disciples who lack influence. Like the tribal disciples of Floating Army, at that time, they only need to let the tribal people act, and the demon core is almost guaranteed. But if there is no power, they have to do it themselves.
