He had to change the entire path of the spiritual energy whirlpool to maintain the second revolution.
During the process of devouring, the vortex would rotate in reverse, forming a vortex inside the vortex. Then, it would rotate in the third rotation.
It was exactly the same as the spiritual strength vortex that was changing in Gu Mingzhou's body.
This meant that not only had he entered the earth realm, but he had also cultivated the third level of the Heavenly Devouring Technique!
The third level of the Heavenly Devouring Technique was a qualitative leap.
After cultivating to the third cycle, the spiritual energy whirlpool would last forever, and it would be condensed in the Dao Foundation without dissipating.
There was no need to use the Heavenly Devouring Technique to form a vortex again before devouring, so time and efficiency would be increased.
