In an era when the civilization of cultivating immortals was at its peak, a seemingly crazy young man unveiled an existential crisis that subverted cognition. Mo Chen, an abandoned disciple of the Qingyun Sect, was despised by the world because he could see the terrifying truth behind the world. The world of immortality in his eyes is not a fairyland surrounded by auspicious clouds, but a terrifying realm filled with unspeakable things - the wriggling tentacles in the spiritual energy, the twisted shadows in the Taoist law, and the peeping eyes from behind the sky. After being abolished and expelled from his master's school, Mo Chen met Su Miaoyin, the saint of the Pure Land of Glazed Glass, on his way into exile. This Buddhist cultivator, whose mission is to purify evil spirits, originally wanted to bring this "crazy" young man to justice, but discovered the shocking truth in crisis after crisis: Mo Chen's "crazy words" were actually insights into the nature of the world, and the "hallucinations" in his eyes were the true face of the world. When the martial arts and Taoism that the world of immortality is proud of are vulnerable to external evil spirits, and when the respected leaders of the immortal sect are transformed into terrifying monsters one after another, Mo Chen's "eyes of truth" that are feared by the world have become mankind's last hope. He must learn to walk the tightrope between sanity and madness, harnessing the chilling power of taboo on the edge of cognitive contamination.
