The one with long purple hair was naturally Zi Yan, but at this moment, a terrifying pressure that made Xiao Yan's heart tremble emanated from her body. This pressure seemed to originate from the liquid-like golden longsword in her hand...
The South Dragon King also stared blankly at his empty arm. After transforming it into a dragon arm, his body's defense had reached an extremely terrifying level. Even if a Five-Star Dou Sheng struck it head-on, his arm would not have been severed so easily. Yet... "Dragon Slaying Sword? It's the Dragon Slaying Sword? You can actually summon the Dragon Slaying Sword?"
His daze lasted only an instant before the excruciating pain from his severed arm jolted him awake. The South Dragon King abruptly raised his head and looked at Zi Yan as she stepped through the air. His gaze finally stopped on the golden liquid longsword in her hand, and his pupils instantly shrank to pinpoints. A shrill cry of disbelief burst from his mouth.
At the side, the West Dragon King's heart also shook violently. His originally crimson eyes filled with utter horror. His entire body trembled as he stared at the golden liquid longsword in Zi Yan's grasp, fear finally surfacing on his face.
The Dragon Slaying Sword was not a weapon, but an ultimate Dou Technique of the Ancient Void Dragon clan. Only Ancient Void Dragons possessing the purest royal bloodline could unleash it. Even the Three Dragon Kings could not perform it. Yet they had never expected Zi Yan to be able to summon it now. One had to know that even the previous Dragon Emperor had only barely managed to summon the Dragon Slaying Sword after reaching the Six-Star Dou Sheng level, while Zi Yan was merely at the early Four-Star Dou Sheng level!
