Happy Community Resident Rules

When Lin Mo inherited the old apartment left by his aunt, he thought it was a windfall, but found himself entering a maze of rules that he could not escape from. The Happy Community seems ordinary, but it has a series of rules for residents that must be strictly followed: you cannot open the door to strangers at night, you can never press the elevator button on the 13th floor, and you must go home immediately when the wind chime on the balcony rings... As Lin Mo gradually investigates the truth about his aunt's death, he discovers that this community is not only a cage, but also a huge living altar, and he himself has long been one of the sacrifices.
