Gu Beichen, heir to the Gu Group, refuses to be the CEO of a trillion-dollar empire, preferring instead to wear a white T-shirt, hang a ring of keys on his belt, and act as a landlord collecting rent. In a fit of rage, his father freezes all his bank accounts, little knowing that he casually flashes a balance of 3.2 billion—turns out years of collecting rent have built another commercial empire. A popular female celebrity, a female tech company CEO, and an arrogant upstart renter take the stage one after another. While collecting rent, Gu Beichen casually invests 100 million yuan, going head-to-head with his father's arch-rival Shen Wanhao. The landlord who refuses to inherit the family estate uses a bunch of keys to unlock his own trillion-dollar underworld of wealth.
