Fog City, a modern city shrouded in eternal fog. During the day, it is a bustling and noisy steel jungle; after nightfall, those "things" hidden in the folds of the city begin to move around.
You thought you would be greeted by ordinary college life. Until that midnight, the sound of sobbing came from the study room...
As the investigation progresses, you find yourself embroiled in a vast mystery. You form an exploration team with Chen Mo, a senior student in the history department, and Zhao Qing, a physical education student, and step by step uncover the strange things that have happened in the fog city for hundreds of years: a cursed urban village, an abandoned hospital that conducts human experiments, an online ecstasy that devours players, a haunted century-old house...
What's even more frightening is that all these events seem to point to an unfathomable source of darkness.
Can you believe your eyes?
In this city, the most dangerous thing is often not ghosts, but the living human heart.
Do you dare to step into this fog?
