Zheng Guan, the only scholar in Chinese history who was the first scholar in both civil and military subjects - became the first scholar in the third year of Changqing, and became the first scholar in the martial arts examination in the second year of Yamato. He was supposed to disappear in the chaos of the late Tang Dynasty, but his soul traveled back to Tianbao for thirteen years and possessed the body of Zheng Guan, a young man of the same name. Chang'an seems peaceful, but Qujiang Spring Banquet, Fangshi Wine Flags, and Orchid Tower are extremely prosperous. But the northern feudal towns are watching with eager eyes, the undercurrent of Anlu Mountain is surging, and the three towns of Tongguan, Hebei, and Fanyang are in danger. The gears of history have not yet turned to the moment of disaster. Zheng Guan must use his literary talent and military strategy in his previous life to defend the foundation of the Tang Dynasty and rewrite the fate of a prosperous age that is about to collapse before An Lushan raises his flag. This is a heaven-defying road for both civil and military champions, and it is also a legend of salvation in the cruelest history of the late Tang Dynasty. This time, he wanted to save Datang's life before Fan Yang raised his flag.
