In 755 AD, the prosperous Tang Dynasty fell into pieces under the iron heel of the Anshi Rebellion. Li Wuwang, a young man from Chang'an, was originally a student in Taixue who only devoted himself to reading the books of sages, but his family was ruined because of the rebel army's massacre of the city. He crawled out from the sea of blood and corpses, resolutely joined the army, and grew into a unique general in the baptism of blood and fire. At the same time, he met Princess Yongning, who was living among the people, and got to know each other in troubled times, and they worked together in court intrigues and battlefield battles. This is an epic intertwined with personal destiny and feelings of family and country. It tells the heroic story of how a group of young people stick to their original aspirations and rebuild the country in the tide of the times.
