When Lin Fu, a top student at a modern military academy, accidentally traveled through the ancient battlefield of the late Tang Dynasty in the 14th year of Xiantong during a simulation exercise.
When he first came to another world, he mistook the battlefield for a film set and escaped death by relying on the fighting skills learned in the military academy. However, during the confrontation with the Shatuo cavalry, he gradually understood the era he was in. From carefully pretending to be an "Orion" to avoid trouble, to being appreciated by Li Keyong with his strategic vision, Lin Fu's journey in troubled times began. He has assisted the brave but suspicious General Shatuo, dealt with the hidden ambition Zhu Wen, met brothers who share life and death in the shadow of swords, and also met his unforgettable lover in the ups and downs of troubled times.
The whole book takes Lin Fu's growth as the main line and connects the major historical nodes from the late Tang Dynasty to the early Song Dynasty. There are not only the battlefield battles between the warriors and the iron horses, the step-by-step power game, but also the delicate and touching emotional entanglements. From surviving alone to helping to stabilize the country, from duckweed in troubled times to a generation of counselors, Lin Fu spent his life explaining: No matter what era he is in, his chivalrous heart will never die, and his feelings for his family and country will last forever.
