Lin Mo, a freshman, was randomly assigned to dormitory 307 of the old dormitory building.
On the day I moved in, there was a yellowed piece of paper taped to the back of the door, which contained ten cold rules for survival in the dormitory.
Turn off the lights and don't get out of bed, don't look up at midnight, don't trust your roommates, you must go to bed after dark...
There are true and false rules. You may not live if you follow them, but you will definitely die if you violate them.
Inexplicable footsteps in the corridor, repeated knocks on the door, whispers of empty beds, roommates behaving strangely...
Four boys were trapped in the weird dormitory 307. Some were reckless and seeking death, some were silent and hiding secrets, and some were panic-stricken.
There are no yin and yang eyes, no metaphysical plug-ins,
Only the thoughtful Lin Mo, relying on calm observation and logical deduction,
Little by little, you can dismantle false rules, see through strange traps, and distinguish between human hearts and ghosts.
In this campus dormitory shrouded in ghost stories, he is trying to survive every step of the way.
