On a snowy night at the border, the pawn Pei Zi awakens to three major systems: military deduction, insight into people's hearts, and resource plunder. On the surface, he is slick and pandering to the superiors, but in reality he is sincere and sticks to the bottom line. In order to eradicate dissidents, the powerful minister Yan Yan trapped the border troops, deducted food and wages, and even colluded with foreign enemies to cause bloodshed. Pei Zi used the system to secretly lay out the chess game: deduce and break the enemy's formation, discern the alienation plan, and plunder and replenish military supplies. The imperial court showed weakness and strategized outside the border, causing the strict party's minions to defect one after another. The victory report of the border army shocked Jiuzhong. When the irrefutable evidence was presented to the Golden Palace, the powerful officials knelt down and screamed "Who are you?", Pei Zi rolled his sleeves and chuckled: "I am an honest person, but the world forces me to act." The rhythm is full of strong and refreshing, and every chapter is reversed and slapped in the face, watching the soldiers of the border army defeat the power with wisdom, defend the country with heart, and become an immortal military god!
