As the Seven Heavens of Ice and Fire cultivation technique operated, the fire spiritual energy within Lu Yu's body decreased, while his Qi blood continually increased.
Nourished by the Qi blood, the meridians burnt by the fire spiritual energy began to restore, and over time, new, more resilient meridians appeared within Lu Yu.
The final trace of the fire spiritual energy vanished completely, and the auto-cultivation stopped. Lu Yu's consciousness took back control of his body.
He never expected that he would turn misfortune into a blessing and start cultivating the Seven Heavens of Ice and Fire.
Through this event, Lu Yu understood the cultivation conditions for the Seven Heavens of Ice and Fire.
One only needs to find items or environments that can provide fire spiritual energy to cultivate the Seven Heavens of Ice and Fire. Similarly, one also needs items or environments that can provide ice spiritual energy.
