Gao Xuan also went through thousands of experiments to find this most efficient way of fighting.
The Eternal Celestial Dragon Claw can absorb the Ultimate Yin Filthy Qi, but the Qi in the Cave of Ten Thousand Demons is too turbid and chaotic. Transforming it with the Eternal Hell Seal is very troublesome and inefficient.
Thus, using the World-Ending True Flame to refine the demon's leftover Essence Blood can obtain pure Essence of Demon Power. The Eternal Hell Seal hardly needs transformation and can be directly absorbed.
In this way, the Eternal Hell Seal can quickly accumulate power. The powerful Eternal Hell Seal, in turn, can enhance the might of the Great Mighty Celestial Dragon Seal and boost the power of the Eternal Celestial Dragon Claw.
At this point, it entered a virtuous cycle. The more demons killed, the stronger the Eternal Celestial Dragon Claw becomes. The stronger the Claw, the more demons can be killed.
