The lights in Chang'an City were as bright as day, and at the farewell banquet for Chao Heng, the Japanese envoy to the Tang Dynasty, the song "The Music of King Qin Breaking the Formation" came to an abrupt end - the chief musician of the envoy died in the banquet, leaving only a wisp of fragrance and an extinguished bronze candlestick beside him. This is the first ignition of the "strange fire".
Within three days, the royal horse mysteriously disappeared, and the mother-of-pearl and rosewood five-string pipa given by the imperial concubine disappeared amid heavy guards. At the scene of every mysterious crime, the candles and incense must be extinguished. Rumors in the world are rampant, and the target is implicitly pointing at Fan Yang and Shen Gong.
......... What was stolen was not a simple national gift. In the belly of the pipa, there is a volume of "Kaiyuan Prosperity Illustrated Book" written in the code of music, dance scores and craftsmanship - a "living" treasure that carries the soul of the civilization of the prosperous Tang Dynasty. The mastermind behind the scenes is trying to bury it forever in the yellow sands of the Western Regions and cut off this spark of civilization that will illuminate the future.
Qi Guan Jingxuan and Liu Mingsha left Yangguan in the west, and under the gaze of the Thousand Buddhas of Mogao Grottoes, they raced against time and various forces. When the flying sky on the mural seems to tremble with the ancient music, when Anlu Mountain's cavalry has beaten the Yuyang war drum, they must solve the final puzzle: How to make a "living" civilization pass through conspiracy and war to reach the other side where it should go?
This is an extreme pursuit under the gorgeous curtain of the end of the empire. The strange fire illuminates not only strange cases, but also the glimmer of trust, the weight of civilization, and the eternal moments that humans choose to guard before the cliff of history.
