Li Xuanke, the concubine of General Dingbei's Mansion in the Great Chu Dynasty, was repeatedly suppressed by his concubine due to his humble mother and humble son. He occasionally received the golden finger of "strategic enlightenment" and emerged in crises such as ethnic debates and hunting dangers. Just when the Hu cavalry invaded the border in the north, he joined the army as a civilian. With his sudden understanding of military strategies, he made many ingenious strategies and was gradually promoted from the Huotou Army to the partial general. In the process, he not only had to resolve the frame-up of his brother and the scheme of his stepmother, but also had to deal with the contempt of the old generals in the army. In the life-and-death game with Hu Qi, he also uncovered the truth about the old "collaboration with the enemy" case of Dingbei Gong. In the end, he rectified his name with military merit, restored the glory of the general, and guarded the country with the female general Mu Qingli. Highlights: The concubine's counterattack and military strategy are intertwined, and family ethics and battlefield tactics are deeply integrated.
