From Rented Room to Villa King

At thirty-five, Lin Feng faces bankruptcy and his lowest point when flight attendant Gu Wanqing, along with her quadruplet daughters, suddenly appears and demands marriage. Struggling to support them alone, Lin Feng unexpectedly binds to the Super Dad System, which offers tenfold cashback for every expense made for the children. Leveraging this, he counters snobbish people and the villain Wang Xiaoren, transforming his agreement marriage with Gu Wanqing into true love. When the powerful Lin family in Jiangcheng pressures him due to old grudges, Lin Feng uses his trillion-dollar wealth accumulated from the system to crush his opponents, reclaim his ancestral property, and finally holds a grand wedding with Gu Wanqing, bringing complete happiness to his family.
