In ancient times, a mysterious ethnic group known as the "Xuhai Civilization" suddenly disappeared. It is said that they mastered the secret method of communicating between heaven and earth, and recorded all their wisdom in nine volumes of Qingming Slips. Modern archaeologist Shen Yan accidentally salvaged the first volume of Qingming Slips during a deep-sea archaeological expedition, and has since been involved in a puzzle that spans thousands of years of civilization. He formed an expedition team with Ye Hongxiao, a descendant of a family of tomb robbers, Lei Zhan, a former Marine Corps elite, and Mo Wentian, a master of mysterious metaphysics, to track down the Qingming Slips scattered across the land of China. From the ancient underwater city in the East China Sea to the Kunlun Ruins ruins, from the secret chamber of Dunhuang Mogao Grottoes to the primeval forest of Shennongjia, they not only have to crack the ancient institutions and supernatural curses, but also fight against the "Shadow Alliance", a transnational cultural relic smuggling group, and the ancient organization that guards the secrets of the Ruins. As the Qingming Slips gradually gathered together, they discovered that these bamboo slips were not only carriers of knowledge, but also the key to unlocking the resonance of human consciousness and the universe, and were related to the evolutionary direction of the entire civilization.
