In the seventh year of Qi Yuan, the Shatuo tribe in Mobei invaded the country. Shen Yanzhi, the ninth-rank commander, brought an urgent report to Beijing and unexpectedly met the upright and daring Princess Li Mingyue of Zhaoyang. From rescuing the siege in Yanmen Pass, to the undercurrents in the palace of the capital, to protecting each other in life and death on the battlefield at Taniguchi, the two are closely connected by protecting the people on the border and uncovering traitors.
The struggle for the throne between the crown prince and the second prince in the court intensifies. There is hidden collusion behind the harassment by the Shatuo people on the border. There is even a shocking conspiracy hidden in the grain and grass accounts of Daizhou Prefecture. Shen Yanzhi sticks to his original intention with sincerity, and Li Mingyue bravely takes on the mission as a princess. The two work together to break the chess game in troubled times, and write a passionate chapter to protect the Dajing River and Mountains amid the swords and intrigues.
