Beneath the neon lights of bustling Jiangcheng lie strange, little-known rules.
The urban legends passed around the streets are never just rumors: the stairwell where you mustn’t look back at midnight, the last bus that’s always empty, the extra figure in the mirror, the unfamiliar calls you mustn’t answer at three in the morning…
Lu Chen, an ordinary office worker, unexpectedly rents a century-old house in the old district and is swept into a vortex of urban legends.
He discovers that every urban legend follows hidden rules, and breaking one means certain death.
He can see eerie traces invisible to ordinary people and uncover ways to survive the legends, but an unseen darkness has its eye on him too.
As one urban legend after another becomes real and disappearances and bizarre murders multiply, Lu Chen finally understands:
The city we live in has long since been infiltrated by the bizarre. Staying alive is nothing more than a gamble in which you must follow the rules with utmost care.
