Lin Xiu transmigrates into the world of courtyard houses, becoming a lowly apprentice whose parents are both dead. The moment he arrives, he is caught in a moral blackmail scheme organized by Yi Zhonghai to “raise money for the Jia family.” Just as everyone pressures the poorest man there to cough up cash, the “Great Philanthropist System” activates and tells him: Want to stay alive? Do charity. How you do it is up to you.
Lin Xiu smiles and immediately turns the tables, piling praise on Yi Zhonghai: “The First Master really is the kindest man in our courtyard. With the salary of an eighth-grade worker, you'll surely lead the way by donating half your wealth, right?” His words take effect. Yi Zhonghai, unable to control himself, goes home for his bankbook and stuffs money into the donation box through his tears.
From then on, the courtyard has a new “great philanthropist.” He forces Yi Zhonghai to donate all his savings, makes Liu Haizhong sell his house, makes Jia Zhangshi send Banggeng out to sell his blood, and forces Xu Damao to hand over his entire salary... Everyone who once used moral blackmail against others is ruined by his “charity.”
Meanwhile, in the name of charity, Lin Xiu protects Lou Xiao'e from Xu Damao's domestic abuse. His charitable work expands from the courtyard to the factory, then to the neighborhood and the entire district. He racks up “good karma points,” rises through the ranks, and wins the hearts of beautiful women along the way.
