Pei Xixi, the young lady of the Minister of Revenue's household, transmigrated for eighteen years only wanting to slack off and eat well, until she bound with a melon-eating system that exposes secrets at a palace banquet. She thought her complaints were all hidden in her heart, but little did she know that all the court officials, even Emperor Uncle, could hear them loud and clear! A single inner voice exposes the problematic cup of wine at the banquet; a single complaint roots out the black-hearted steamed bun stall and the deceitful tavern. She eats melons at court and opens shops after court, seeking justice for the common people. But as she keeps eating these melons, how did they end up reaching her own home?
