The protagonist Yunmeng died due to bullying in her previous life and was reborn as the aunt in charge of heaven. Faced with the arrogant and ignorant Koi Jing Nishang and the dim-witted and partial Prince Ling Xiao, she tolerated her plans and worked step by step. From being poured hot wine, framed and humiliated, to taking advantage of others' strength and turning against the guests, Yunmeng used her wisdom and skill to drag each of her opponents into the quagmire, and was eventually promoted to the crown prince and concubine, taking charge of the power of the heaven. At the same time, Siming Xingjun quietly appeared and joined forces with his junior sister to stir up trouble in the three realms. A heavenly chess game that subverted blood and class had just begun.
