A week after blue spore fog blankets the globe, humanity thinks the nightmare is over.
But true hell has only just begun.
After waking from a fourteen-day fever-induced coma, veteran Lin Feng discovers that the world has become a breeding ground for fungi. Vein-like networks spread across the land like nerves, reaching deep underground to some unknown mother organism.
The blue lights flickering in the darkness are their signal to hunt.
His younger sister mysteriously disappeared before the blue fog arrived, and the antibodies in Lin Feng's body seem to conceal the secret behind this disaster.
As the cities are consumed by fungi, we are hunters by day, and prey by night.
And those beautiful blue spores, like fireflies, may be the beginning of an even greater conspiracy!
