Yang Tian, a white-collar worker, was watching a short drama when he saw an innocent extra being humiliated by the brainless protagonist with a "system." He casually complained, only to be unexpectedly transported into the drama. To return to his world, he had to defeat four male leads with absurd “systems” (Immortal King, Cash-Back, Divine Doctor, and Master Chef). Using his knowledge of the plot and available resources, Yang Tian cleverly exposed the true nature of these brainless protagonists one by one. Along the way, he won the favor of the drama's female leads. In the end, he had to choose between staying in the drama world and returning to reality.
