During the Great Yan Dynasty, there were internal and external troubles. There were barbarians in the north and vassal kings in the south. {Xiao Ce} unexpectedly awakened the "god-level military control system", but because of his low status, he chose to hide behind the scenes.
He used the refugees to form a private army, exchanged the system for "Xuan Jia Heavy Cavalry" and "Zhuge Liangnu Camp", and relied on war deductions to predict the enemy's movements; when the barbarians invaded, he secretly assisted the border troops in setting up an ambush, killing 30,000 enemies without leaving their names; when the vassal king rebelled, he sent his dead soldiers to disrupt the enemy camp, and helped the court put down the rebellion but stayed behind.
"My soldiers don't need me to charge personally." Xiao Ce lives in a shabby room, but he mobilizes thousands of troops and horses with a secret order and turns the tide of the battle with sand table deductions. When the barbarians bowed their heads and the vassal king surrendered, Emperor Dayan was shocked to realize that the man who supported half of the dynasty was actually the man behind the scenes that no one knew about!
