If fate sent you plunging toward an earth-shattering fall, would you still dare to rebuild your soul among thorns for the sake of a promise?
Zhou Shengchen, the God of War of Northern Chen, is framed, branded a traitor to the emperor, stripped of his martial arts, and imprisoned in the imperial mausoleum. On her wedding day, his disciple Cui Shiyi leaps from the city wall, and everyone believes she has died. Three years later, she awakens in a border town under the name Wenjun, with no memories, only an all-consuming sorrow that follows her like a shadow.
She teaches, draws maps, and tries to find traces of her past in a peaceful life. Though imprisoned, he makes plans in the snowy imperial mausoleum, secretly protecting the crumbling realm and her one remaining chance at survival.
As the Southern Xiao prince's probing and the pursuit by powerful figures from her homeland converge, Shiyi's memories gradually return. She resolutely infiltrates the heart of Southern Xiao's power, making herself a chess piece and coordinating from afar with the man in the imperial mausoleum to lay a plan that will overturn the world.
This is a bond between master and disciple that transcends life and death, and a battle to clear a name stained by slander. When the injustice is finally righted and peace returns to the land, they reunite in the place where it all began. Every sacrifice and every moment of waiting was for the sake of fulfilling that most heartfelt promise: “We'll go home.”
