By chance, Li Yan, a college student who was lying flat, traveled back to the body of a person with the same name who was born in the Li family in Longxi during the Tang Dynasty. He originally thought that he could enjoy the glory and wealth by traveling to the prosperous age of the Tang Dynasty. "What? An Lushan rebelled?" "What? Tubo actually captured Chang'an!" What's even more tragic is that he was serving in the Anxi Protectorate at this time. Because Tubo captured the Hexi Corridor, this vast land in the Western Regions completely lost contact with the imperial court. At this time, the Western Region was isolated and helpless. Externally, the Uighurs and Tubo were eyeing them. Internally, elite soldiers and generals had been transferred to the Central Plains to suppress the rebellion. The troops were empty and people were panicked. If nothing unexpected happens, after Hexi, Beiting and Anxi will also fall into the hands of foreigners. Li Yan was about to cry but had no tears. "Hey, I am not a master of the Tang Dynasty. I am a royal man. I just want to continue to be a mess!" "The organization has already decided that it is up to you to help the Tang Dynasty." In this way, Li Yan had no choice but to embark on a legendary life of restoring the Western Regions, supporting the Tang Dynasty, marrying women of five genders, and serving as a copycat.
