The bloody demon star fell to the ground for thirteen years, the sea of stars was annihilated, and the earth was barren. Every dusk, the purple mist spreads over the rusty city outline like living creatures, giving birth to fog nightmares that feed on living creatures. The orphan Ling Yan lives amidst the ruins, and the carvings on his fingertips record the desperate days when the mist shrouded the world.
When a silver leaf badge slipped from the mysterious cloaked man, the legendary "Mist Keeper" was no longer a false rumor. When Uncle Mo's cloudy eyes reflected the ominous purple mist, Ling Yan tightened his grip on the spear forged from the railroad tracks - should he huddle in the wooden house and wait for the end, or should he step into the fog to pursue the truth?
The silver leaf with the star map engraved on it was quietly guiding the path to the point where the demon star fell. And deep in the purple mist, in addition to the secrets of the catastrophe that were buried thirteen years ago, there seems to be some kind of sleeping existence, slowly opening its eyes as the star path shifts.
