{Yun Shuran}, a girl from a medical clinic in the mortal world, is gifted with the ability to distinguish elixirs and poisons, and has saved countless lives with her medical skills. By chance, she rescued a seriously injured alchemist and was able to enter the Qingyun Sect of the Immortal Sect and specialize in alchemy. She relied on her keen sense to refine poison pills and healing pills that were both offensive and defensive. She used poison pills to defeat the geniuses of the sect in the Immortal Sect Competition and became a blockbuster. Unexpectedly, her glory was fleeting, and she was falsely accused of colluding with the devil and became a public enemy of the sect. In order to prove his innocence, Yun Shuran broke into the dangerous Valley of Poisons alone, and unexpectedly got a glimpse of the fragments of ancient alchemy, which actually involved the Qingyun Sect's poisonous conspiracy that had been hidden for hundreds of years. Using pills as blades and poisons as shields, she navigated the treacherous plot step by step, and finally purified the turbid currents of the sect, and embarked on a unique path to elixir that blended medicine and poison.
