In the fragile peace between dragons and humans, Ouyang Ling, who was once one of the core executors of the "God-killing" plan, shouldered the important task of killing the defecting dragon warriors. With the blood of the dragon clan, he has been carrying out orders ruthlessly, but he gradually began to question the meaning of it all. During a mission, Ouyang Ling discovered that he was not just a tool, but a pawn of fate. There was a surprising secret hidden behind the "God-killing" plan he believed in.
His target is Herman, a defected dragon warrior who has mastered the power to control dragon spirits and is ambitiously trying to reshape the world order. As the investigation deepened, Ouyang Ling discovered that Herman was not only his enemy, but also the key to uncovering the mystery of his own identity. As the past is gradually revealed, Ouyang Ling begins to face a major choice in life: continue to carry out the mission of "killing gods", or betray his former beliefs and pursue his own path?
