Su Qinghuan, a modern-day migrant worker, suddenly transforms into the legitimate daughter of the Prime Minister's Palace, but she doesn't know that she has a hidden setting that "the whole capital can hear her voice". She is also entangled in the "Royal Melon-eating System", and her mission is to uncover the secrets of the court and uncover the spies behind the scenes.
She usually relies on her inner complaints to eat, but accidentally helps the emperor clear away internal troubles; her five brothers and one sister dote on her, and the prince and Prince Jing are attracted by her "candid voice" and secretly fight to protect her. The built-in murderous intention rebound mechanism makes the villain suffer the consequences, but she is completely unaware of it. She only focuses on unlocking new functions of the system and watching ancient gossip.
From the fate of cannon fodder to the "invisible assistance" of the court, Su Qinghuan's ancient life is a joyful drama of being loved while eating, and counterattacking at the same time.
