Sent to the Far North, I Create an Invincible Divine Army with My Own Hands

At the beginning, I was framed and exiled to the extreme northern ice field of death, without food or clothing, and all the civil and military officials in the court were waiting to eat me? Sorry, I am an all-around survival master and a master of the art of war! No system plug-ins? The wisdom of the ancients is the most powerful weapon! At minus 40 degrees, I searched for geothermal hot springs, built underground heating cities, and planted polar cold-resistant snow wheat. Barbarians are attacking? I set up the Qimen Bagua Array, a series of traps to trap and kill thousands of people! Ten years later, the Daqian frontier army suffered a series of defeats and was forced to flee north, but was shocked to discover—— In that legendary barren land, there is actually a huge stone fortress that is more majestic than the imperial capital! On the city wall, there are strong bows and crossbows like a forest, and grain and grass are piled up like a mountain! The barbarian Khan collapsed: "It was promised that there will only be savages in the far north? Who taught this invincible divine army?!"
