Song Wei conquered Jinyang and regained the lost territory in one fell swoop, determined to eliminate the Liao intelligence network entrenched in the Song and Northern Han Dynasties. He ordered his intelligence organization, Wude Division, to carry out a shocking plan: to forge the long-lost strategic treasure "Map of the Sixteen Prefectures of Yanyun". The new deputy military envoy Shen Jinghong, with his courage and resourcefulness beyond ordinary people, understood the emperor's true intention. The core strategy he proposed was not simple forgery, but to create a "cognitive trap": use nine parts of true historical facts and one part of carefully designed "flaws" to guide the enemy to self-verify, so that they would accept this fake picture as the truth after paying a huge price. This plan aims to take advantage of the enemy's own expertise, suspicion, and greed to induce all of his spies and hawks to be exposed in order to seize the map, and ultimately to catch them all in one fell swoop, clearing the final obstacle to the expansion of the Song Dynasty. This is a deadly hunt that uses the entire enemy country's intelligence network as a bet and is planned with people's hearts and information gaps.
