Deliveryman Qin Yang accidentally rescues Jiang Muxue, the daughter of the Jiang Group, who suffered a car accident. In order to preserve the inheritance rights, the other party's parents invited Qin Yang to marry him with a reward of 100 million. At the wedding scene, Qin Yang activated the "surprise lottery system" and needed to obtain points to redeem props by stimulating Jiang Muxue's brain waves. After the marriage, Qin Yang used the Dahuan Dan and other gifts given by the system to not only improve Jiang Muxue's physical condition, but also repeatedly repel the killers sent by Jiang Anfei. Qin Yang relied on his system skills and his own wisdom to see through the killer disguised as a nanny and thwarted Jiang Anfei's assassination plan. During this period, his bond with Jiang Muxue gradually deepened.
