Careful

In such an environment, only Immortal Saints could protect themselves with some measure of success. Immortal Essence cultivators could only hope that an eruption didn't happen near them. 

"Careful." Dyon suddenly said. "An eruption is about to occur over there in just about 3 more seconds." 

After saying these words, Dyon didn't stand on ceremony and swerved Chibi's cauldron. Crystella's ears perked up and swerved as well. 

There wasn't much of a chance to doubt Dyon's words because mere few ticks later, the ground blasted apart. 

A pillar of fiery red and gold, holding out with a diameter of 50 meters shot into the skies, piercing through the smoggy blue above. In this kind of atmosphere, the clouds couldn't even last, leaving nothing but a greyish blue all around. 

Droplets of molten lava became the only rain they knew, falling from the skies to be accompanied by the screams of pain the Immortal Saints behind them left.
