In 2068 AD, after the heavy snowfall that lasted for forty-nine days, the northern hemisphere entered an ice age. The survivors hid in the underground city for twenty years.
When Gu Shanhe walked out of Underground City No. 2078, He was twenty years old and his identity was a "cuboid solid engineer" - a brick mover. He didn't know what kind of world this truck bound for the north would send him into: the provisional government fell apart and warlords divided the country; the Japanese archipelago was submerged, the Korean west coast was lost, and foreign enemies were sharpening their knives; the United States annexed neighboring countries, established the "First Special Zone", and looked across the Pacific.
Amid internal and external troubles, some people knelt down to beg for mercy, while others took advantage of the situation to rob them. Gu Shanhe and several companions who climbed out from the bottom chose the third path.
From the construction site in Yanbei, to the warlord's team, to the anti-Japanese front line in the mountains of blood and corpses - it took them twenty years to grow from immigrants with nothing to the founders of the Eighth Special Zone.
After that war, Tokyo sank into the Pacific Ocean and China reshuffled its cards. Their next generation will take over the banner of the 9th District.
