The Country Is Destroyed? I Am the Last Knight!

Orion said it was gone, and I, Richard, became the last knight in the kingdom! Behind them were all the barbarians from the Khanate pursuing them. With only a few remaining soldiers in hand, and no food or armor in their pockets, it was a desperate start. Fortunately, God has opened his eyes and provided a system that can make the brothers stronger as they fight! Establish a resistance base, cultivate wasteland, mine and make weapons, and slowly build up your family fortune; We will suppress the bandits when we encounter them, rob the barbarian grain depots when we see them, fight against the regular army, or fight against the magician bosses, we will never give up! What if the country is destroyed and the family is destroyed? As long as I am still standing, I will lead the brothers to drive out the barbarians and raise the flag of Orion! I, Richard, am the last knight!
