Meanwhile, thanks to the System's rewards, Xu Cheng earns a high salary, has plenty of ration coupons, and fills the courtyard with the aroma of meat. He even marries Yu Li, the factory beauty. Watching him thrive, Qin Huairu regrets it bitterly. In this life, he'll be the toughest man in the Siheyuan and make every one of those troublemakers kneel and call him Dad!
