In the sixth year of Yuanyou in Daliang, war broke out again in the northern border. The powerful enemy Dayu joined forces with Ye Qin and Beiyan to suppress the border. Changlin's army was in danger. At the same time, a mysterious annotated copy of "Xiang Di Ji" was quietly introduced into Langya Pavilion. The handwriting was exactly the same as that of the late Jiangzuo leader Mei Changsu...
In the Suzhai outside Jinling City, the fire in the small red clay stove is as bright as a bean. A thin figure wearing a moon-white scholar's shirt was playing chess with the current emperor, Jamel Xiao. He raised his eyes and smiled softly, his face was still pale, but there was no shadow in his eyes anymore, only the clarity and determination that could see through the world. "Jingyan, this time, I am not seeking power or avenging grievances, I am only here to guard the Qingming River and Mountains for the people of the world with you."
At the same time, above the rivers and lakes, an organization named "Spark" rose rapidly, specializing in punishing evil that the court could not handle; outside the border, the mysterious "Kilin Talent" became a nightmare for the enemy commander. Mei Changsu returns to the world in a triple identity, intertwined with Xiao Jingyan's imperial palace, Meng Zhi's cavalry on the battlefield, and flying heroes and heroines, and composes a great epic of love, family and country, inheritance and rebirth.
