A ten-kilometer-diameter meteorite crashes into Earth, and humanity's desperate interception may determine their fate. The dust from the impact blocks out the sun, plunging the world into a centuries-long, freezing dark night. The sunless surface is plunged into sub-zero temperatures due to the lack of sunlight. In this apocalyptic world, with only a self-dug shelter and a salvaged upgrade system, how will Chen Xin survive the end of the world? Can human civilization continue, and can the flame of hope illuminate this cold night and bring warmth to humanity? Fate has presented the test; can humanity deliver a different answer than the dinosaurs who were once extinct?
