In the autumn of the thirteenth year of the Apocalypse, the beacon smoke suddenly arrived in Mobei. Yunzhou was in urgent need of food and grass assistance, but the Zichen Palace in Chang'an was in a deadlock due to the empty treasury. Li Qianmiao, the daughter of Zhongcheng, the imperial censor, stepped forward in the name of "acting on behalf of her father" and pointed out the long-standing abuses of the powerful in the capital by occupying fertile land and evading taxes. She presented evidence to solve the urgent needs of the border troops, but was refuted by the Minister of Household Affairs and criticized by the court.
At the critical moment, Zhang Shuyi, the minister of the Ministry of War who came from a poor family and had no party or affiliation, came up with a plan to solve the situation. He not only solved Yunzhou's food and grass shortage, but also secretly gave Li Qianmiao a deputy to mobilize troops to help him thoroughly investigate corruption. Although Li Qianmiao is grateful, she is wary - Zhang Shuyi seems to be fair, but it is rumored to be related to the Duke of Zhen who was wrongfully demoted ten years ago; and among the powerful people she wants to investigate, there are many gang members of the second prince, and Su Wenyan, the cousin of the prince's faction, is also worried about her being retaliated against.
On the one hand, there is the urgent military situation at the border, on the other hand, there is the secret fight between the court factions, and on the other hand, there are suspicions about the old case of Zhen Guogong. Li Qianmiao takes charge of the censorship station as a woman, and Zhang Shuyi establishes himself in the Ministry of War with his talents from a humble family. From the temptation of the first confrontation to the secret understanding between the Communist Party and the powerful, in the turbulent Chang'an court, they must not only eliminate the long-standing abuses and protect the country, but also clarify their position and explore the truth in the chess game of power. When corruption cases gradually intertwine with old injustices, their choices will affect the fate of the entire Tianqi Dynasty.
