The dragon princess Ao Xuewei knelt in the Northern Wilderness, begging Yang Ce, a powerful hidden man, to help resist the invasion of the monster empire. Yang Ce sneered: "I was the one who destroyed your entire clan back then." However, she did not get up. Instead, she held up a dragon clan's most precious treasure - the ancestral dragon scale. Yang Ce saw that the scales were deceptive, but he had to accept the deal due to an old injury. And Ao Xuewei secretly joined forces with Chi Yan, the elder of the dragon clan, and Liu Rushi, the saint of Tianji Pavilion, to plan a series of killings. When the army of monsters and beasts presses against the border, a chess game about the truth about dragon slaying, blood revenge and ancient secret treasures slowly unfolds in the blood and fire.
