Dayong had been a country for more than a hundred years, and the northern border had been lost for many years. However, the court emphasized civility and suppressed military power. The army's food and salary were exploited at every level, and the generals became the most easily discarded people. The protagonist was born as a general, and both his father and brother died in a deliberately concealed defeat. He faked his death to escape. After returning to his hometown, he found that if he wanted to reverse the case, take charge of the army, and change the cannibalistic rules, it was not enough to rely on a knife, but also to enter the game through the imperial examination. But once he entered Shilin, he had to disguise himself as a humble and polite scholar, and deal with it repeatedly among the examination room, prefectures and counties, the court and the border army. The core contradiction of the story is that a man who should have established his career through military exploits, instead used his articles to knock on the door of power, and then used his power tactics to rewrite the military and political structure.
