He Yuzhu is reborn in the Siheyuan, where a game in his mind lets him kill monsters and earn real cash! Kill a chicken and it drops coins; slaughter a pig and it drops a wad of cash. He escapes his bloodsucking neighbors, marries a beautiful wife, and finds bargains at the pigeon market. How did this game suddenly become a money-making cheat code?!
