The heroine Jiang Suisui is the daughter of the late "criminal general" and is forced to marry Huo Wujiu, the god of war general of the Yan Kingdom. After three years of marriage, Huo Wu Jiu was extremely indifferent to her and regarded her as a useless dodder flower. The first thing he did when he returned from triumph was to hand over a letter of divorce. Jiang Suisui was crying on the surface, but in fact he was ecstatic inside. He took a huge amount of alimony and ran away decisively. He used fake death to escape, changed his name to "Jiang Sui", and defected to Da Chu, the old enemy of Dayan who had been at war with him for many years.
Relying on her father's military books that she had read since she was a child and her extraordinary military talent, she started as a soldier in the Huotou camp, won people's hearts with delicious food, trained with strange tactics, repeatedly performed extraordinary feats, and counterattacked all the way to become the feared "white-robed military advisor" of the Great Chu Kingdom.
When Huo Wujiu led the Yan cavalry to the city again, he discovered that the enemy commander on the opposite side who was strategizing and fooling him around was actually his ex-wife who had been abandoned by his own hands! The former ruthless "overlord" general has since begun the endless journey of "chasing his wife in the crematorium" in front of the tens of thousands of troops. The whole book focuses on the battle of wits and courage, love and death between the two on the battlefield, interspersed with the funny daily life in the military camp and the suspenseful line of rehabilitating the father. In the end, the couple join forces to reveal the huge conspiracy behind the war between the two countries, and jointly protect the peace of the world.
