After working overtime for days on end, Shen Yueli suddenly drops dead and transmigrates into the body of a discarded empress awaiting execution. She is also bound to a Lie Flat System. The System stipulates that as long as she relaxes and stays out of palace intrigues, she can earn supplies while doing nothing and exchange them for skills. Her only beginner’s gift, however, is a pair of naturally bewitching peach-blossom eyes: anyone who meets her gaze falls for her, and the effect automatically reaches a hundred meters. Shen Yue plans to hole up in the Cold Palace, eat her fill, and wait to die without getting involved in any trouble, but those eyes keep causing problems out of nowhere.
At their first meeting, the cold-faced Emperor Xiao Yan is bewitched by a single glance. He storms off to depose her, only to turn back halfway. The System takes the opportunity to issue an outrageous mission, forcing her to actively draw the emperor into visiting her again and again in exchange for youth-preserving pills. Shen Yue can only go with the flow and lie flat, using her peach-blossom eyes to keep the emperor in check while fiercely guarding the peace of the Cold Palace. She has no interest in the throne or his favor.
Empress Zhao Weitang fears that Shen Yue has bewitched the emperor and repeatedly tries to poison her and send assassins after her. The Grand Tutor secretly plots a coup, hoping to use her to eliminate the emperor. With hypnosis and time-stopping skills exchanged through the Lie Flat System, Shen Yue easily defuses every crisis, and her mind-reading skill sees through everyone’s schemes. Xiao Yan goes from suspicion to complete surrender, willingly abandoning the women of the six palaces to dote on her alone. He is even willing to give up his throne to keep her company in the Cold Palace.
Yet Shen Yue never strays from her resolve to lie flat. She never fights for favor or schemes her way to power. With nothing but her peach-blossom eyes and her Lie Flat techniques, she foils every assassination plot, making the emperor willingly revolve around her and throwing both the harem and the court into turmoil. In the end, all she wants is to stay in Cuiwei Palace, lie flat and eat fruit every day, with someone by her side. No cutthroat palace competition, just an unconventional discarded empress winning through life, with lighthearted sweetness and thrilling power struggles.
