The more frantic thing is that while Lu Yu was operating his Qi Blood with full force to resist the erosion of the Yinming Cold Qi, he simultaneously ran the Ice and Fire Seven Layers Cultivation Technique to actively absorb the Yinming Cold Qi into his body.
Lu Yu's Qi Blood was simultaneously resisting the internal and external erosion of the Yinming Cold Qi, causing the consumption rate of Qi Blood to accelerate by three or four times, forcing Lu Yu to activate the Celestial Falling Bright Flame within his body to resist the erosion of the Yinming Cold Qi together.
The Celestial Falling Bright Flame guarded the exterior, preventing a large amount of Yinming Cold Qi from invading the body, but in the cold pool, the power of the Celestial Falling Bright Flame was severely suppressed and could extinguish at any moment.
