In the chaotic Spring and Autumn period, the feudal lords vie for supremacy. Tian Rangju, a son born outside the main line of the Qi ruling house, carries the Tian clan’s blood but is trapped in humble circumstances. His mastery of military strategy goes unrecognized until the joint forces of Jin and Yan threaten Qi and the state stands on the brink of collapse. Chancellor Yan Ying recognizes his talent and recommends him for command on the battlefield.
Newly entrusted with command, he sets up a time limit and executes the inspector Zhuang Jia when it expires, forging military discipline in blood. He beheads an envoy at the camp gate, sending tremors through the three armies. With fire oxen, he smashes the enemy camp; with a feint and a secret march, he secures the Central Plains. Wielding the Book of Sima, he dominates the warring states, rising from an obscure commoner in Dong’e to the “God of War of Qi,” feared by all.
Yet power struggles in the court are even fiercer than those on the battlefield. Framed by the Bao clan, distrusted by the Tian clan, and shunned by his ruler, the man whose achievements overshadow his lord cannot escape the fate of “when the cunning hare is dead, the hunting dog is cooked.” Even more tragic is his relationship with Zhuang Jiang, Zhuang Jia’s younger sister. They go from crossing swords to falling in love, but family feuds and national hatred turn every step into a trial. The crown prince of Yan harbors hidden feelings, while assassins from Wu and Yue wait for a chance to take his life. Love and hate intertwine as danger lurks at every turn.
As the undercurrent of the Tian clan’s rise to replace the Qi ruling house sweeps through court and country, the loyalty he has upheld all his life becomes a weapon in the hands of schemers. Will he let himself remain a pawn, or break the deadlock with the edge of his blade? See how this god of war in a chaotic age uses a book of military strategy and a long spear to write his own bloody legend amid the flames of the Spring and Autumn period.
