Li Xiao, a modern special soldier, traveled to Anxi of the Tang Dynasty and merged into the Flying Eagle Scout with a broken knife in his hand. In the Shule Oasis, he dealt with the Tibetan and Uighur forces. He used modern tactics to improve crossbows, devised ingenious schemes, set fire to the company, saw through traps, and counterattacked to break the situation. He led the remaining soldiers to rise from despair, and wrote a passionate legend of the Flying Eagle Scout on the battlefields of the Western Regions.
