They Cultivate Their Immortality

This world is being forgotten. Gu Chen, the Ninth Grade Recorder of the Hanlin Academy, discovered a terrifying fact: the handwriting in ancient books would disappear out of thin air, the village household registration would become blank paper, and after his colleague disappeared, no one would remember that he ever existed. The world of immortality calls it "spiritual energy flushing" - history is impurities and needs to be purified. But Gu Chen is an anomaly. He can remember everything that has been erased, and there are countless memories that "should not exist" hidden in his mind: disappeared folk customs, tampered heroes, and completely annihilated cities. He is the last "black box" of civilization, a walking history keeper. When Xie Wuwu, the head of the Jingshi Department - a terrifying being who turned himself into a "hollow saint" - launched a comprehensive purge, Gu Chen was forced to flee with the blind harpist Jiang Li. She is his only spiritual anchor, and the sound of the piano can soothe the historical torrent that is about to burst his head. They travel through the gray wilderness, collect scattered fragments of history, and fight against a machine that rules the world with "nothingness". The memories of mortals should not be the fuel for cultivating immortality. They cultivate their immortality, and I guard my human world.
