In the Eternal Night Apocalypse, I Have a Little Sun

The bitter cold descends, and the eternal night begins. Global temperatures plunge to minus sixty degrees, and darkness swallows the last glimmer of light. Blizzards seal off cities, order collapses, and the spark of civilization flickers on the brink of despair. While the rest of the world kills over a moldy piece of bread and shivers over half a lump of coal, Chen Xuan unexpectedly obtains a miniature sun. Its golden light drives away all cold and hunger. Beneath this eternal night, he is the one and only god.
