An intelligence analyst from the National Security Agency disguised as the son of a subjugated general, faced with the chaos of Kyushu that was about to overturn, he only had an "Introduction to Intelligence" at the beginning. While the enemy is still playing undercover countermeasures, he has already started engaging in communication interception, radio silence and information asymmetry warfare. The protagonist Shen Zhou comes through time just as the city is being destroyed. He used the micro-expression observation and psychological profiling of modern intelligence science to accurately identify the moles in the army in front of the enemy commander, thereby saving his life and being recruited into the shogunate as a "monster". At this stage, you mainly rely on "mind-reading" tricks to save your life and obtain initial development resources.
