The War in Chang'an: Record of the Setting Sun in the Prosperous Tang Dynasty

What kind of map strategy is this? This is clearly a detailed military defense map of Anlu Mountain's lair, which is under the jurisdiction of Fan Yang Jiedushi! It was embedded in an inconspicuous old glass lamp in such a secret way and flowed into Chang'an West Market! Li Ling felt a cold air rushing from the soles of his feet to Tian Ling Gai, and the blood all over his body almost froze. The "border movements" and "wolf ambitions" mentioned implicitly in his father's letter, as well as the rumors in the court about Anlu Mountain's "must rebel", were now transformed into the cold and biting picture in front of him, with the smell of bloody rust coming to his face. During the Lantern Festival, the whole country is rejoicing. Under the bright lights, the huge shadow has quietly opened its fangs like a lurking beast. And he, an insignificant Imperial College Supervisor, became the first person to glimpse this fatal secret.
