Sword Sect disciple Shen Fang has mediocre aptitude, yet awakens his family's divine skill of character-changing—turning "overturning mountains and seas" into "overturning mountains and milk," and "fierce tiger fist" into "cute tiger fist." Using clever ingenuity, he breaks through dangerous situations, protects his fellow disciples, and investigates the truth behind his father's murder, unearthing a conspiracy where the Immortal Alliance leader colludes with the Blood Demon. Joining hands with Mu Qingshuang, Shen Fang changes characters to defeat demons. The conspirators are brought to justice, and through his sense of responsibility, he grows into the new generation leader of the Immortal Alliance.
