I Have a Thousand Victories in My Mind

Cross von Royce, a midshipman in the Iron Crown Imperial Border Guard. He has in his mind a whole series of battles that have not yet been fought in this era. He didn't recognize the blueprints and couldn't memorize the parameters. He only knew one thing: which way would work and which way would be a pitfall. So when the retreat order was sent to the position, he said no retreat was allowed. Everyone thought he was crazy. Four hours later, the retreating team was cut off on the road. From then on, the empire had a young man who didn't look at the map, but could always figure out where the enemy was going. He calls it common sense.
