"After Rebates of 100 Billions, I Spoiled My Stepson into the Top" tells the story of Lin Wan who married into the Qin family for joy but was expelled by her husband's family after her husband passed away. In a desperate situation, she was bound to a ten-fold rebate system and the task target was her stepson Qin Mo, who was hostile to her. She tried the water system with 18 yuan of beef, and started a life of spending money for Qin Mo and relying on rebates to counterattack. From renting a house of 2,000 yuan and getting back 20,000 yuan, to donating 50,000 yuan to send Qin Mo to a top private middle school, to hiring famous teachers to protect Qin Mo from bullying at school, every investment made by Lin Wan was rewarded tenfold, which made Qin Mo take off his guard and go from calling "Aunt Lin" to calling him "Mom" sincerely. Faced with Qin Jianye's embezzlement of inheritance and Su Manni's malicious obstruction, the mother and son fought back together, not only regaining Qin's assets, but also relying on the rebate system to establish a technology company and develop intelligent educational equipment. With the support of Lin Wan, Qin Mo won the gold medal in the physics competition and was recommended to Tsinghua University. The mother and son expanded their business territory internationally and devoted themselves to charity to support rural education. The fetters that started with interests eventually settled into the most sincere family affection and the glory of growing together.
