In the thirty-seventh year of the Ice Age, human civilization is lingering on the permanently frozen wasteland. Carrying the last nuclear fusion fire, Yunqi traveled through the dead zone of minus 120 degrees, just to reach the legendary Aurora Ark. Lu Ye, once the youngest genetic engineer in the military, is now a wanted traitor - he personally tore up the last hope agreement of mankind. When the pursuers crush the frozen soil and the fetal movement of the baby in the cryopod stops abruptly, they have no choice: either let the fire be buried in the ice and snow, or use their flesh and blood as wages to ignite the first ray of light for mankind to return to the earth.
