In the world of cultivation, he was reduced to a bed slave of a saint and a drug tester. Lin Qingya took the Qi Refining Pill for half a year and still had no cultivation. He suffered from the pain of the poison every day and the humiliation of pleasure every night. In a desperate situation, a piece of yellow paper that spontaneously ignites after being burned and tortured turns out to be the fragment of the "Heart Sutra of Ten Thousand Poisons" that has been lost for thousands of years. He awakened to the heaven-defying ability to perceive spirituality and taste a hundred medicines to survive. It coincided with the Alchemist's restriction that he must enter Qi refining before August 15th, otherwise he would be expelled from the mountain gate. What was once a plaything, now uses poison to enter the Tao, knows all kinds of poisons, and transforms into elixirs. What this Dannu wants to refine is not only a magical elixir, but also a destiny-defying legend that overturns the world of cultivation!
