Huangquan Town, a dead place shrouded in strange rules and rumors. As midnight falls, strange things run rampant, and those who violate the rules will surely die.
In the small town tavern, there is always a night watchman in black. He looked coldly at the travelers who followed the rules but still died miserably, and revealed the hidden truth in one sentence - on the seventh day of the leap month, the moon has no soul. From the beginning, it was not the shadowless things that died, but themselves.
He is the last night watchman in Huangquan Town, guarding the old clock that always stops at midnight, guarding the endless rules, and guarding a bloody past that no one knows about. He doesn't save people, he doesn't avoid evil, he just waits for someone who can kill him.
As strange rules and stories are cracked, his fragmented memories are gradually pieced together: Who is he? Why are you trapped here? And why do you want to die?
From being in awe of his mystery to feeling sorry for his loneliness. This time, you will see clearly that the night watchman never watches the night, but his own sins and fate that will never be freed.
