The Seven Kingdoms are in chaos. Beneath the setting sun over the wasteland, young Murong Jin watches his father, Marshal Murong Yuntai, die beneath the Northern Liang cavalry while protecting the Manual of the Endgame. The words written in blood on the silk, “The Seven Kingdoms are a game of chess, and all living beings are its pieces,” become his obsession: to break the game.
After three years on the road, he meets Su Ningshuang, a witch doctor from Southern Chu. Together, they take the manual to the Snow Mountain's Lingxu Pavilion, a mysterious tower that conceals the power of three divisions: the Shadow Guards, the Mechanists, and the Deathsworn. Murong Jin solves the unfinished chess puzzle at the pavilion's gates with a gambit, refuses to be anyone's pawn, and challenges the pavilion master, Xie Xuanyi. In the end, he claims the position for himself and commands Lingxu's many hidden forces.
He reunites with his father's old Northern Guard troops at Yanling Pass, using intelligence from the Tianshu Division to devise strategy, the Dixuan Division's mechanisms to defeat the enemy, and the Renji Division's elite fighters to protect the people. He and Su Ningshuang also remain bound together by a soul-sharing Gu. Amid a blood-red chessboard, he avenges his father without surrendering to slaughter. At last, he overturns the old game and makes the Manual of the Endgame, a strategy for bringing peace to the land, public knowledge. With Lingxu's power, he protects the people, ensuring the Seven Kingdoms are no longer pieces on a board and that everyone can make their own move. This is his path to the throne: protecting the people while holding fast to the woman he loves.
