The World-Corrupting Poison

"Hmm!?" Bai Yueyin's expression changed as well when she saw this scene. Her condition was extremely poor, and she desperately needed the Divine Nectar Stone Marrow in this pool to heal her injuries. These Demon Servants could not do anything to her, but they had contaminated her Stone Marrow Divine Pool. This move was tantamount to cutting off the firewood beneath the cauldron.

"The World-Corrupting Poison!?"

Yi Yun drew in a sharp breath. When Bai Yueyin heard Yi Yun's words, she looked at him in surprise. Clearly, she had not expected that although Yi Yun was young, his knowledge would be so extensive that he could even recognize the World-Corrupting Poison.

In this world, poison was also a law. Ordinary poisons found it difficult to harm extraordinary experts, but there were always people who researched the Poison Law to its extreme.

The World-Corrupting Poison came from the decay of a great world. Nothing under Heaven and Earth could exist forever—not even a great world. For example, the Great World of Green Wood that Yi Yun had once visited was facing collapse, with World-Ending Smoke erupting everywhere. The World-Corrupting Poison had been refined from all the decayed matter of great worlds, including the World-Ending Smoke. It could even corrode a great world, so its toxicity to humans was self-evident.

Moreover, Yi Yun could sense that the person who had extracted the World-Corrupting Poison was extremely powerful. Otherwise, he could not have injured Bai Yueyin, much less forcefully opened a spatial passage in this cavern of the Ancient Battlefield.

Naturally, the poison's power grew even more terrifying as a result. The current situation was clearly because the person who had extracted the World-Corrupting Poison had bound the poison within the Demon Servants. Once a Demon Servant died, the World-Corrupting Poison would erupt
