The Yin Qi of Death and the Divine Qi that were at their full potentials were now in the state of…one leads, one follows.
Every spot that Xueming propelled the Yin Qi by, the accumulated Divine Qi would burst out, destroying it right after. The remaining Yin power in Xueming’s pulses then became useful for him, as it was able to remove the hidden dark Qi at once.
But to be frank, Xueming could not direct the Qi to run conveniently without obstacles, or even if he could, the Qi power that he used to lure would probably be totally destroyed before reaching the Eye of the Primordial Demon. However, the reason that Xueming was able to do it this time was because of the remaining Qi power of Ta Long that helped open a way, separating the damaged Qi pulses for Xueming.
