An ancient imperial court judge was poisoned during a palace struggle, but his soul accidentally traveled to modern times and possessed a college student also named Kang Mowen. Not only does he have to adapt to this bizarre new world, he also has to face the deadly toxins remaining in his body. By chance, he hatched a mythical beast named Pixiu that could swallow poison and feed it back to him. One person and one beast, complementing each other, embarked on a legendary path to practice poison, and eventually became a poison doctor.
