Divination Through the Underworld

On the seventh day after Shen Fu's death, he heard no sobs from his wife. All he heard was a scream. When he opened his eyes, gray mist filled the underworld. Before him stood a stone tablet: Find an exit through the mist within one hour. One dead. Ninety-nine remain. In life, he had been a diviner at the Grand Astronomical Bureau. He had studied fragments of the Three Changes and calculated the outcomes of ten thousand hexagrams. He crouched and cast a hexagram with the skills he'd honed over seventeen years as a diviner. Mountain above, water below: Meng, Youthful Folly. The exit couldn't be found. It could only be "sought." The Meng hexagram trial, the Song hexagram trial, the Shi hexagram trial... After clearing seven trials, he obtained the Guicang Seal and opened the Guicang Terrace. Then he discovered something. The Heavenly Dao had died long ago. It hadn't died a natural death. Someone had altered it. And the Guicang Seal on the back of his hand was the Heavenly Dao's true name, as well as his own. A wandering soul who owed his wife an explanation. A diviner at the Grand Astronomical Bureau, murdered by his superior. A man whose fate had been arranged since the day he was born. He would use the sixty-four hexagrams to uncover who had altered the Heavenly Dao. Then he'd go back. Infinite-flow survival + solving crises through the I Ching + underworld intrigue. Each trial corresponds to a hexagram, and every breakthrough is an act of divination.
