In the troubled times of the late Tang Dynasty, the Huangchao Uprising swept the Central Plains, the Tang Dynasty fell apart, and the eleven prefectures in Hexi Province that Zhang Yichao ordered to recover were in turmoil.
Shen Yan, a refugee who was rescued from the dead by Zhang Yichao, was involved in a shocking conspiracy for protecting the refugees on the day when he had been guarding the tomb for three years. Massacres and frame-ups, power struggles, and alien races surrounding him, he entered the situation with his own body, tearing apart the truth of the troubled times in the blood and fire.
He did not ask for the title of prince or prime minister, nor did he seek power in Hexi. In the troubled times where the sky was full of yellow sand, he served as the night watchman of the people of Hexi, guarding the orthodoxy of the Tang Dynasty and protecting the lights of thousands of families.
