Chen Bin, a 27-year-old small-time advertising company clerk, is handed nine nieces by several older sisters, activating the "God-Level Uncle System" where completing tasks with his nieces grants a thousand-fold rebate. Next, he slaps the faces of his high school classmate Sun Yutong and second-generation rich kid He Ziyang who mocked him. Afterwards, he reunites with Bai Bingyan, the heiress of the Bai Group, who also joins in with the identity of "aunt" to pamper the nieces together. From a monthly salary of four thousand to a net worth of tens of billions, Chen Bin wants to prove what kind of nieces an uncle can raise nine of.
