Doomsday is sweeping across the earth, order is collapsing, the fire of civilization is crumbling, and human history is being swallowed up by the wave of forgetfulness. {Mo Shu}, a doomsday historian with a special mission, holds a rusty pen and a heavy historical book, wandering between the desolate land and scattered survivor bases. He recorded the story of blood and tears of struggling to survive, and witnessed the glory and despicability of human nature. However, in the mottled diary and dusty archives, he glimpsed a cruel truth - the end of the world is never a natural disaster, but the evil consequences planted by human hands. When the survivors are addicted to survival, {Mo Shu} resolutely embarks on a thorny road. He wants to engrave the buried truth into the annals of history and pass it on to the next generation, leaving the last hope of awakening for the sinking world.
