Winter descends upon the Central Plains, and blood stains the snow. Princess Qinghe is slain by the Great Chanyu, igniting the Murong clan's thirst for vengeance. Amidst the chaos, Xiang Shu and Chen Xing make a desperate escape with the help of Tuoba Yan, while Fu Jian demands justice--accusing Feng Qianjun of the princess's murder. But just as the blade is about to fall, Feng Qianyi appears--with the stolen Yin Yang Mirror in hand--and unleashes a nightmare upon the capital. The dead rise by the thousands, the living turn against each other, drowning the city in horror. Now, Chen Xing, Xiang Shu, Feng Qianjun, and Tuoba Yan must unite against an army of the undead and the dark sorcery that controls them. Bound by fate and battling for humanity's last light, they awaken a mysterious power within Xiang Shu--one that could tip the balance between salvation and oblivion.
