"Not an Innate Realm warrior?" Yun Wen asked, puzzled. According to his experience, anyone who could kill twelve people in a Conscript Task and earn the right to choose, tended to be a strong Innate Realm warrior.
Because the Innate Realm has a vast range of power levels. Factors like magical artifacts, combat skills, principles of movement, and the level of control over the forces of nature, could all possibly give an early stage Innate Realm martial artist a strength that far surpasses his apparent level.
Post-Innate martial artists, on the other hand, don't have that kind of flexibility. Their battle power has little room for improvement, nor do they have the endurance of those in the Innate Realm.
On the battlefield, Post-Innate martial artists are at the bottom of the food chain! In such a Conscript Task, survival alone is a tough enough challenge, let alone completing a task that involves killing twelve of their peers.
