Qiao Nian time-traveled from the apocalypse and, the moment she opened her eyes, faced the desperate crisis of her mother-in-law trying to sell her twin children. She decisively rescued her son and daughter, went to town to look for her scholar husband Li Yongnian who had been away for five years without returning, only to find that he was living and having children with his widowed sister-in-law under the pretext of a dual-line marriage. Qiao Nian made a prompt decision, beat up the scoundrel couple, and used his scholarly reputation as leverage to force him to sign a divorce agreement and a kinship severance letter, making him pay sixty-nine taels of silver in compensation. Afterwards, Qiao Nian emptied the Li family's assets, returned to the Qiao family with her children, established an independent household and did business relying on modern medical skills and space supplies, led the whole family to wealth, and formed an unbreakable bond with the mysterious male lead Zhan Baihan through mutual probing.
