Lin Xiao, a special soldier, accidentally traveled to the Zhenguan period and rewrote history with the help of modern military knowledge: he improved the crossbow to double the range, innovated the tactics of the Xuanjia Army, used the "empty box strategy" to repel 100,000 Turkic cavalry, and was granted the title of deputy commander of the Tiance Guard by Li Shimin. He introduced corn cultivation to Anxi's farms, established a cavalry industry chain, and even secretly developed black technologies such as the "Shenhuo Flying Crow". The love across time and space with the medical girl Su Tang runs throughout, and the two discover the mysterious connection between the Dunhuang star map and the code of modern drones. After sealing the wolf in Xu and pacifying Goguryeo, Lin Xiao foresaw the threat of the Arab Empire's eastward expansion and left a "Memorandum of Attack and Defense in the Western Regions" predicting the Battle of Talas. In the end, he took his wife and retired to Zhongnan Mountain. Before his death, he embedded space-time meteorite fragments into the murals, forming a closed loop of cause and effect that spanned thousands of years. The novel combines real historical events with science fiction imagination, showing the rise and fall of the Tang Dynasty and the game of time and space from the perspective of special forces.
