In ancient times, Shennong explores the forest deep in the valley to collect unknown plants with unique tastes and effects. A glamorous flower seduces Shennong and he is poisoned by tasting the petal. Shennong falls in illusion as the flower turns into a mythical beast, which torches Shennong to his last breath. In the despairing darkness, Shennong is revived by a secret friend. With the awakening superpower, he conquers the beast, breaks the illusion and acquires another valuable plant.
