Unknown: Dark Age

As an interstellar explorer, Lake encountered an accident during a mission and entered a planet he had never known before. All kinds of abnormal pollution sources are embedded in every living thing on this planet. The wailing and struggling sentient beings are doing their best to survive, and the small and fragile human beings are digging their bones and understanding their hearts in order to survive. Lake has seen all these things, but he doesn't know whether he will successfully escape or become a dead soul here.
