In the "Taste Harvest Era" in the near future, human taste genes are monopolized by the technology giant "Sweet Party" through "Sweet Gene Editing Fluid", causing 90% of the world's population to lose their perception of "sour, spicy, and bitter". Lin Wanxing, the documentary director of "The Journey of All Worlds", embarks on a journey to solve the mystery of taste civilization through three thousand years in order to find the genetic map of the "taste guardian pepper" left behind by his missing mother. She used Zeng Houyi's "double-tone resonance" technology as the key to unlock the golden ratio of dicarine (bitter antibody) and capsaicin (spicy antibody), ultimately awakening human taste freedom for the balance of the five flavors of "sour, spicy, bitter, sweet and salty".
