The Silent Files of Longyou

In the early years of the Chui Gong era of the Tang Dynasty, dark currents hid deadly schemes in the western frontier. A murder in a mountain valley unraveled a twelve-year-long silent spy case in Longyou! Di Renjie, the prefect of Ningzhou, newly arrived at the border, encountered Su Yan, an orphan of a frontier garrison family that had been destroyed. The young man, bearing the injustice of his family's ruin, traversed the vast Gobi alone, tracking down the mastermind behind the framing of the Su family. Witchcraft in Ningzhou, a poison camp in the desert, blood sacrifices in Qiang lands, and a grain blockade west of the Yellow River—four bizarre cases in four locations were intricately linked, each clue pointing to a secret underground chamber beneath the residence of a powerful minister in Luoyang. Su Yan, holding irrefutable evidence, rushed a thousand miles to the eastern capital, while Di Renjie, seated in the imperial court, coordinated with him on two fronts. A confrontation in the Zichen Hall, a rebellion by private guards outside the city, an army pressing at the border, and eunuchs hiding traitors within the palace—twelve years of injustice would be settled by a single secret volume. The treacherous faction was brought to justice, the border crisis subsided, Su Yan retired in success to guard the Gobi alone, and Di Gong upheld governance and stabilized the realm. With the loyal souls of the Gobi as the pen and the secret documents of the western frontier as evidence, this tale captures the espionage of the Tang border, the intrigues of the court, and a heart devoted to defending the land. — Description from novelcodex.org
