Modern woman Wang Jinzhu accidentally time-traveled to ancient times, becoming the new daughter-in-law of the Chen family's eldest branch in Houkou Village. Facing the biased and exploitative Old Madame Chen and the weak, bullied eldest branch, she established strict rules on her very first day of marriage, protecting her husband Chen Tianfang and her younger siblings. Relying on modern vision, she made soap, aloe vera gel, and floral water, opened workshops, set up shops, and built a courtyard, leading the whole family to prosperity and wealth. She supported her relatives in studying and growing, and also helped Chen Shujie, who had been sold, regain a new life. Ultimately, Wang Jinzhu successfully counterattacked from a farm daughter-in-law into a wealthy landowner of the region, leading the clan toward prosperity.
