Du Qiu seemed to have thought of something, his pupils trembled suddenly, and he whispered, "Are you talking about the Wandox Poison?"
Han Qing nodded, "Yes, aside from the Wandox Poison, I don't believe there's any antidote in the world that can counteract the poisons of Falling Frost and Soul Sever."
Du Qiu said decisively, "Impossible, the Wandox Poison is the Supreme Treasure of our Life-Seeking Sect, only the Sect Leader of the Life-Seeking Sect is entitled to consume it. Drinking it not only makes one immune to all poisons but also extends one's life."
"Moreover, our Sect Leader has been missing for decades, his life or death remains unknown. How could Xu Wendong have possibly consumed the Wandox Poison?"
Han Qing's face showed a bitter smile, "But how else do we explain Xu Wendong being poisoned without any symptoms?"
