Lin Xuan, a college student, sacrificed his life to save others and accidentally traveled to Zhenbei to become the great general Xiaren. As soon as he defeated the Hun royal court with his illustrious military exploits, he received an imperial edict from the emperor asking him to remove his armor and go to Beijing. He knew clearly that it was a conspiracy to "hide the bow when the bird is gone", but he temporarily compromised due to the constraints of his family. Fortunately, he was bound to the summoning system and had a huge sum of eight thousand taels in his hand. When he entered the capital, he would summon heavy armored cavalry and change his destiny to conquer the world.
