[House fighting + rebirth + exchanging relatives and remarrying + becoming a man's mother + slapping a time-traveling woman in the face + ten-year age difference + doting on his wife] Bai Jinshu and his sister were reborn together. The younger sister exchanged their marriages in order to marry a poor family. On the wedding day, the groom asked the brothel girl and Bai Jinshu to become the crown prince's wife. Faced with the humiliation, she directly remarried Song Heci, the eldest son's adoptive father. From then on, everyone was betting that Bai Jinshu would not survive three days. Either he was tortured to death by the ruthless old lady of the Duke, or he died of depression as a living widow in the Duke's mansion. Later, people heard that Duke Song Heci had a humble attitude and walked out of the Duke's mansion holding Bai Jinshu with a bulging belly. Bai Jinshu not only survived, but also became the mistress of the Duke's Mansion and was canonized as the Imperial Lady by the Holy Emperor. That little life was prosperous, as majestic as you wanted.
