As though it sensed the auras of the thousands of Grotto-heavens outside, there seemed to be a mysterious power flowing on the surface of the Netherworld Treasure Mirror, gradually forming a gray vortex.
Immediately after, a powerful devouring power burst forth from the Netherworld Treasure Mirror!
The Grotto-heaven powers that the Essence Martial Grotto-heaven could not digest immediately were devoured by the Netherworld Treasure Mirror and the pressure on the Martial Dao Prime Body decreased.
That change happened in the Essence Martial Grotto-heaven.
The spirit consciousnesses of Ming Feng and the other Nether King and Hell King experts could not enter the Essence Martial Grotto-heaven that was deep and dark, so they naturally did not know what happened.
Initially, the Essence Martial Grotto-heaven of the Martial Dao Prime Body had already gradually stopped spinning.
