Four hours later, Yi Yun was already greatly enervated from the continuous powering of the Heretical God Fire Seed. As for Poison Demon, not only was it still feeling energetic, it was becoming stronger as it absorbed large amounts of World Decay Poison. Its body had expanded greatly in size and its eyes turned deeply profound as though it was connected to another world.
Yi Yun could sense that its strength had increased by more than ten times, with plenty of room to grow further.
Thankfully, Yi Yun had planted a slave mark in Poison Demon, guaranteeing its loyalty. If not, he would have cause to worry if any thoughts of betrayal surfaced in it.
Poison Demon was absorbing the World Decay Poison at a speed far greater than Yi Yun was burning it away, so Yi Yun took some time to stop powering the Heretical God Fire, consume a pill, and began meditating.
