Lin Yuan, a "concept-level" strongman who was tired of fighting and killing in the multiverse, chose to retire and return to his hometown, Earth, to retire. In order to experience true ordinaryness, he disguised himself as an ordinary community security guard. But he didn't expect that there were crouching tigers, hidden dragons in this seemingly ordinary community, and a bunch of keys he bought at random turned him into the landlord of these "hidden bosses". Thus, an urban myth of pretending to be a pig, eating a tiger, and hearing thunder in a silent place began.
