Ling Xi lies low in the human world as a healer while gathering clues about the Star Marrow under the name “Ye Luo.” But a bizarre “shadow murder” brings her face to face with Mo Yuan, who is using the alias Xie Yunlan. From testing each other to being forced to work together, they gradually uncover the truth behind the Shadow Clan’s extermination. As clues to the Star Marrow emerge, the Celestial Realm’s schemes, the Dragon Clan’s ambitions, and the Demon Clan’s position become entangled. Ling Xi’s identity as a member of the Shadow Clan and Mo Yuan’s dragon bloodline are exposed in turn, leaving the former “enemies” struggling on the edge between love and hate.
Their friends, the quick-witted A Zhu, the perceptive Siming, the smooth-talking Feng Ci, the stubborn Elder Xuan, the reclusive Cang Yue, and the complicated Ao Xuan, each harbor their own secrets and aims. In this conflict spanning the Three Realms, some stand by their principles, some waver, and some sacrifice their lives for the cause. When the mastermind’s plot is revealed, the Celestial Regent sought power by arranging the Shadow Clan’s extermination and imprisoning the Dragon Clan princess, Ling Xi and Mo Yuan must set aside their clans’ grievances and join forces against their formidable foe. Their choice will determine the future of the Three Realms and the survival of the Shadow Clan.
