Wu Sicheng, the young master of the Wu family, placed an order with "Bai Shi Tong Da" to find someone to protect him and help him take back the Wu family's property from his brothers-in-law. Hua Shengtang, the daughter of the Hua family who had an engagement with him, was unwilling to accept her family's arrangement, so she also placed an order with the platform to find a substitute to marry into the Wu family. As a gold medal employee of "Bai Shi Tong Da", Song Zhizhi enabled the group order function, spent one effort and earned twice the money, and thus Song Zhizhi was involved in the struggle of the Wu family. By outsmarting the second brother-in-law and the third brother-in-law, he took back the property that originally belonged to Wu Sicheng, and Wu Sicheng also slowly fell in love with Song Zhizhi as they spent time together.
