The Sect Leader nodded. During humanity's most difficult times—the Ice Age—all families retreated to sunless sanctuaries for survival. Yet, the most powerful families still had the strength to remain active on the surface. Slaying demons remained a priority task. Despite the humans barely ensuring their own survival, they persistently eradicated the surviving Demon Race on the continent. Even though humans were extremely weakened, the Demon Race was in a more dire situation, having lost the Demon Empress. Most powerful demons went extinct in the late stages of the Immortal Demon war. The ones who survived were of inferior quality. After ages of trials, the Demon Race's frailty surpassed that of humanity.
The Ice Age was undoubtedly a mass extinction for weakened species. Humanity perished by ninety percent, let alone the Demon Race that faced harsher conditions?
