The protagonist obtains the long-lost "ancient dragonborn lord system" and can obtain the blueprint for building dragonborn buildings by devouring the magic crystals deposited in the nodes of the earth's veins, and domesticates and evolves the aberrant beast into a "dragonborn beast" with some dragon characteristics. This breaks the traditional path that mages need to meditate to understand elements and knights need to practice fighting spirit, and perfectly combines the "lord farming style" and "dragon cultivation" of the fantasy world. Every time the protagonist controls a leyline node, he can summon the remnant soul of a famous dragon-born hero in history as a heroic spirit general. These heroic spirits are both mentors and combat units, making up for the protagonist's own shortcomings of no magical talent and fighting spirit.
