Delivery worker Su Mu was ruthlessly abandoned by her girlfriend Bai Qianqian on the lie of "taking the public exam". When he was frustrated, he accidentally activated the "tenant rebate" system. Not only did he obtain a top-notch apartment in Shanghai worth tens of billions, which he could only rent but not sell, he also unlocked a wealth code that allowed tenants to get a hundred times rebate on their spending. Su Mu dealt with the tenants and used the magical power of the system to start a completely different cheating life.
