Undercover Elixir: Starting from Refining Erysipelas

Lu Qingxuan was terminally ill and traveled to the world of immortals. The accumulated toxins in his body actually awakened his ability to refine erysipelas. I originally wanted to just peel off the poison and make elixirs, so the cultivator asked. But he is still an undercover agent of the enemy country. The long night is endless, with only poison as a companion. ... Thousands of years later. When people talk about Daqian Danxian and the sage with magical hands, their tone is full of respect and admiration. Lu Qingxuan: Yes, that's me. The Saint of the Immortal Sect leaned into her arms and spoke with a resentful tone: Old Demon of Ten Thousand Poisons, Lord of Five Yun Poisons? Lu Qingxuan: Sorry, I had no choice at the time.
