James Anderson, the adopted son of Family Anderson, sacrificed everything for the clan. He dedicated himself to his elder sisters, doing everything in his power to assist them. Unable to practice cultivation, he nourished medicinal herbs with his own blood to aid their progress, willingly devoting himself to the family. However, his sisters were deceived by traitors, misunderstood James, wounded him, and banished him from Family Anderson. Shortly after leaving, James was accidentally hit by Grace Miller, a beautiful young woman from Family Miller, and nearly became paralyzed. In this desperate situation, he awakened The Power-Up System. After accidentally killing ants and flies, he discovered he could level up— not only repairing his injuries but also enhancing his physique and obtaining resources to aid his cultivation. Using the system, James successfully entered the realm of immortal cultivation, grew stronger step by step, helped his sisters unmask the villains, mended their sibling bond, and eventually formed a lasting bond with Grace, leading a happy life together.
