A slender purple-haired figure—naturally, that was Zhi Yan. Yet, emanating from her body now was a terrifying pressure that sent Xiang Yin's heart racing and his muscles tense. This pressure seemed to originate from the long golden sword she held, which appeared liquid in form. The Southern Dragon King likewise stared blankly at his now empty arms. Having transformed his arms into dragon limbs, his body's defensive strength had reached an exceptionally formidable level—so much so that even a direct blow from a five-star Battle Saint would hardly sever his arms. Yet… "Thy Dragon-Slaying Sword?! Is it truly the Dragon-Slaying Sword? You've summoned it? How is that possible?" This state of dazedness lasted for a moment, until the intense pain radiating from the severed arm jolted him awake. Nan Long Wang sharply lifted his head, gazing at Zi Yan who had stepped forth through the void, and his gaze finally settled on the golden liquid long sword she held. His pupils instantly shrunk to pinpoints, and a sound of astonishment escaped him—shouting out in disbelief. The Tu-Long Sword is not merely a weapon, but a supreme combat technique unique to the ancient dragon lineage of Tai-Xu. This technique can only be performed by ancient dragons possessing the most refined royal bloodline—indeed, even their three Dragon Kings are unable to wield it. Yet, they never expected that Zi Yan, at present, could summon the Tu-Long Sword. After all, even the previous Dragon Emperor could only勉强 summon it after reaching the rank of Six-Star Combat Saint. Now, Zi Yan has only just reached the early stage of Four-Star Combat Saint! By name, the Tu-Long Sword is specifically designed to slay dragons—thus, it is a technique uniquely reserved for Dragon Emperors. Unless an ancient dragon possesses significantly greater strength than the one wielding the sword, any other ancient dragon will be as fragile as tofu beneath its power. "The Sword of Dragon-Slaying..." At that very moment, everyone on Dong Long Island froze, lifting their heads to gaze at the ethereal figure floating in the void, their eyes filled with deep apprehension. Even the mighty Xuan Mo could not help but tremble—this tremor stemmed from the very blood in their veins. The Sword of Dragon-Slaying was the most feared thing in the hearts of all the ancient dragons. "Has the Dragon Emperor truly summoned the Sword of Dragon-Slaying?" The many elders of Dong Long Island stood motionless, their bodies trembling, their eyes glistening with emotion—tears streaming down their faces. Only a Dragon Emperor who could summon the Sword of Dragon-Slaying was a true Dragon Emperor. From now on, Zi Yan would truly hold the authority to command the ancient dragon race. "With the Sword of Dragon-Slaying now forth, who among you still refuses to see the truth? Beware—when the Sword of Dragon-Slaying comes down upon you, your fate shall be beyond redemption!" The Grand Elder of Dong Long Island hovered in midair, holding a dragon-shaped cane, and roared with fierce intensity. Hearing him roar like this, the warriors of Sanzhi's island were visibly shaken, and even Xuanmo and the others dared not utter a single word. The pressure of the Butcher of Dragons spread out from the void, creating a sense of being watched, as though the monstrous creature—so terrifying in its scale, like slaying a chicken—might suddenly descend and strike them down at any moment. At the moment the situation on Donglong Island underwent a dramatic shift, the Western Dragon King also forcibly suppressed his growing fear, roaring in fury and retreating instantly. The Southern Dragon King, too, abandoned his broken arm, his face filled with astonishment as he hurried backward in alarm. "Rebellious ones! Sever them with the Dragon-Slaying Sword!" With cold, impassive purple eyes fixed on the two retreating figures, the voice of Zǐ Yán was as icy and clear as winter's breath. Then, he slowly raised the Dragon-Slaying Sword, and with a sweeping motion, he extended it toward the Western Dragon King. As the sword descended, an unusual ripple surged from the tip, spreading out like lightning. At the very moment the sword stroke was delivered, the Western Dragon King also became aware, his eyes growing even more filled with fear. A low roar escaped his lips, and immediately, layers of dragon scales surged across his head, body, arms, and nearly the entire upper half of his form. These scales shimmered with an unusual luster, appearing as if utterly impervious. Yet, just within a breath, this seemingly extraordinary defense collapsed entirely. The peculiar energy emanating from the Slain-Drake Sword passed through the void, gently slicing across his body. "Shhh-lee!" The ripple swept over him, and the Western Dragon King's face instantly paled. He gasped, spitting out a thick stream of blood, then lowered his head in shock to see a massive, jagged wound slanting from his shoulder down to his waist. There, the once-hard, resilient dragon scales—like soft tofu—cracked cleanly in two, the fracture surface remarkably smooth. Beneath, blood flowed like a river, and faintly, the pulsing organs within his body could be discerned. One sword strike, and the Western Dragon King was severely wounded. The power of the Dragon-Slaying Sword truly proved terrifying even against the ancient, immovable Dragon of the Void. "Ah!!" A piercing, heart-wrenching cry erupted from the Western Dragon King's mouth, resonating through the heavens. The deep, bone-shattering pain caused his body to tremble violently, waves of dizziness continuously overwhelming his consciousness. The Southern Dragon King, standing not far away, felt his hands and feet grow cold. He swallowed hard, his mind now completely focused on one thing—getting away from there. The overwhelming pressure of the Dragon-Slaying Sword threatened to shatter him. "Gurrr..." Xiao Yan also swallowed a lump in his throat, his heart filled with awe. He had personally experienced just how formidable these three were in defense—his strongest, the Devastating Fire Lotus, had only caused them minor injuries. Yet, with just a light stroke from Zi Yan's sword, the West Dragon King had been on the brink of death. "Flee!" South Dragon King roared, retreating swiftly. Realizing that staying meant certain death, the West Dragon King pressed his hand tightly against the jagged wound on his chest, channeling his inner qi and retreating with desperate speed. At the sight of this, Xiao Yan's heart was instantly thrown into shock. "You want to eliminate me completely? Then I'll fight you to the very end!" As Zi Yan drew another sword stroke, a sense of imminent death surged in the hearts of the Western and Southern Dragon Kings. Already severely wounded, they now faced certain doom with this single blow—experience had taught them that beneath the Dragon Slayer Sword, escape was impossible. Both kings were forced to fight desperately, and suddenly, large amounts of pale golden blood erupted from their mouths. "Dragon Emperor Bell!" The golden blood swiftly dispersed in front of them, forming a colossal golden bell several dozen zhang high, which enveloped the two kings. "Clang!" As the golden bell took shape, an unusual surge of energy shot forth and struck it with tremendous force. "Boom!" A tremendous roar echoed, and the golden great bell suddenly rippled with intense waves of disturbance, then exploded in a spectacular burst—right before the stunned eyes of the two Western Dragon Kings. "Shhh!" The shockwaves from the explosion reached the two Western Dragon Kings, instantly severing one leg each. Within just a few minutes, the two mighty dragon kings had become disabled. "Rebellious mere mortals? You dare wield the power of the Dragon Emperor?" Gazing at the devastating sight, Zi Yan's face curled into a cold smile. With no mercy, she drew her dragon-slaying sword once more. "Pls!" The stroke faltered—just as she raised the sword halfway—her slender frame trembled, and a dark golden stream of blood erupted from her mouth. Her face paled. Yet though the sword had not fully severed the connection, a ripple of energy swiftly surged toward the two southern dragon kings, who, even in their severely wounded condition, could only be left stunned and terrified by the rapidly approaching force. "Whoosh!" Just as the two were about to be engulfed by that surge, a figure appeared like a flash of lightning—none other than the northern dragon king, who had remained unseen until now. He seized both of their shoulders and instantly expelled a gush of golden blood, accelerating dramatically. With a few swift movements, he vanished into the void. "Ah!" Not long after the figure disappeared, a sharp, piercing cry echoed from the direction they had fled—clearly, they had not escaped unscathed by that peculiar ripple of energy. "The Three Dragon Kings have been defeated..." Seeing the three figures fleeing in disarray, the temperature in the eastern dragon island instantly dropped as Xu Mo and the others suddenly leapt into the air, joining several of the elder lords in rushing toward every direction. To stay here now would mean certain death. "...What a terrifying blade..." Xiang Yan gazed at the long sword in Zi Yan's hands, which seemed to flow like liquid, and quietly drew a deep breath in awe.
