Yi Tianyun continued onward, voraciously absorbing everything in his path. The process was effortless. Although the Celestial Yin Fire was high-grade, it wasn't difficult to absorb, especially with the aid of the Divine Artifact, the Netherworld Treasure Pearl.
Soon, a large amount of Celestial Yin Fire had been sucked into his body. Beside him, the Great Elder and the others watched with their hearts in their throats. 'Is this really okay?'
Of course, Yi Tianyun was completely fine. He would only grow stronger, with no adverse effects.
He continued to frantically absorb the fire as he followed the passage down. The deeper he went, the denser the Celestial Yin Fire became, and his experience points skyrocketed.
At this rate, it wouldn't be too difficult to upgrade it to a higher Heaven-rank grade; he just needed to absorb for a bit longer.
