Veteran gamer Su An unexpectedly transmigrates into the game 'Eternal Night', returning to its prehistoric version. At this time, the winter deity of the Northern Frostlands has not yet fallen, and the Abyss in the center of the Sea of Ashes is still guarded by black knights. Without the interference of players, the path before Su An leads to two different destinies—the dark, rolling smoke of war shrouds every human city, bringing pain and despair; or, blood-stained banners, carrying human hope, step by step towards Su An's divine throne. There are no players descending, and no Fourth Calamity. This is a pure game-to-another-world story.
