The blood moon shines on broken blades, and the seven great cursed weapons have reappeared in the world. Lin Qingxue, the orphan of the previous dynasty, returns across a mountain of corpses and a sea of blood. She awakens the Seal of Heaven and Earth with a blood sacrifice, and tens of thousands of her former soldiers cast off their disguises and kneel in allegiance. Deep in the underground palace of the Jade Pivot Pavilion, the Ziwei Emperor's soul burns at her heart, and with it, a secret that transcends time and space.
Su Yi, Prince of Zhenbei, bears both a frigid poison and the burden of the realm. Yet after one fleeting glimpse of her in a corner tower, he is willing to point his sword at imperial authority for her. When the Empress Dowager's phoenix crown falls to the ground, the true face of the master of the Dark Nether Pavilion is chilling: an obsession from twenty years ago drove two women onto different paths and stained the land with blood.
When vengeance is over and the snow falls, the jade pendant sends a summons from another world. She leaves behind the word "missing" and vanishes into the altar's white light. He is left alone atop the palace, gazing sleeplessly through the night in the direction where she disappeared. The most painful thing in this world is not loving someone you cannot have, but seeing the land remain unchanged while the person you love is nowhere to be found.
