Now that Mo Xi has uncovered the truth after eight long years, he and Gu Mang finally have a chance to clear away the lies of the past. Both know the moments they share are destined to be fleeting. Despite his efforts to remain lucid, Gu Mang's memories from the Time Mirror continue to slip away, and dark magic eats at his mind.

Yet peace at home is short-lived as new threats gather at the frontier. When the Liao Kingdom attacks once again, Gu Mang will join his former master, Murong Lian, as well as Mo Xi to confront their nation's darkest enemy. Their mission: to neutralize an ancient danger inextricably tied to Chonghua's most secret history.
