During the Northern Song Dynasty, a young man named Shen Kuo embarked on the path to pursue the truth due to a bizarre "Black Eye Disaster".
This erudite man, who was hailed as "the coordinate in the history of Chinese science" by later generations, experienced a legend far more bizarre than "Mengxi Bi Tan" in his life.
From his days as a scholar in Qiantang, Hangzhou, to the ups and downs of the officialdom in Bianjing; from the smoke of war in the northwest border, to his writings in seclusion in the water towns of the south of the Yangtze River - every stage of Shen Kuo's life is accompanied by an unexplained case.
Multiple cases, layer by layer, connect together a shocking secret that spans decades. And at the core of all mysteries, there is always the shadowy existence - Hei Yi.
Is this mysterious entity recorded in ancient books as a "demon and evil thing" a natural phenomenon, or does it have another hidden agenda? When Shen Kuo used the method of studying things he had learned throughout his life to peel off the layers of cocoons, the truth he discovered might subvert the understanding of the entire era...
