Secret Season 3 Night in an Empty City

Author: Cai Jun

Type: novel literature and art >; anxious

A tour group got lost in Thailand, strayed into an underground passage and entered Nanming City surrounded by mountains-although it is so similar to the familiar world, the whole city is empty! Unable to contact with the outside world, the only way to escape was blocked. This is a "sleeping city", and all the residents disappeared overnight. And when the light returns to the sleeping city and opens the dusty "Luo Cha State", can they read their life codes in front of the three gates of the past, the present and the future? Countless suspense continues-what happened in the "big empty city night" a year ago? Whose turn is it to make sacrifices next? Our loneliness is like living in a cemetery? They're heading for destiny!
