Gazing at the young physician who now exuded an eerie aura, Bi Yan's face paled, his confident expression fading into an unmistakable sense of gravity. From the strange atmosphere emanating within her, he sensed a distinct undertone of death. "The厄难毒体—indeed, Iron Monks was right. It must be this very condition that has enabled you to achieve such remarkable progress at your age," Bi Yan said, his voice low and grave. Though he was well-traveled and familiar with the reputation of the厄难毒体, he now spoke with a somber tone. The young physician slowly lifted her gaze. Her eyes—deeply pure, one violet, the other gray—showed no trace of any other hue, conveying an air of cold, unyielding detachment. Even with the strength of Bi Yan's own resolve, the steady gaze of these unusual eyes caused a subtle tremor in his heart. The gray-purple eyes fixed upon Xie Biyan, yet Xiao Yi Xian remained silent. With a gentle grasp of her slender hands, a violent surge of fluctuation rippled through the surrounding ten zhang of space, twisting and distorting until an intangible prison took shape. As the space warped, the view from outside grew increasingly blurred. "Sky-Toxin Prison!" With a calm, detached glance at Xie Biyan, who now found himself completely sealed in with no means of retreat, Xiao Yi Xian gave a subtle flick of her fingers and issued a crisp command. Immediately, a vast expanse of gray-purple, viscous mist surged forth from within her body, spreading rapidly. Within mere moments, it fully enveloped the prison formed by the warped space, completely obscuring the view from outside. Within the spatial prison, Xie Biyan gazed gloomily at the pervasive gray-purple, viscous mist surrounding him. He could feel that this mist carried a potent toxin—one he dared not inhale freely—even as it seemed to impede his speed and agility, making his body feel increasingly heavy as the mist swelled. "Such a terrifying toxin… it's even contaminating the very ambient energy of this sealed space. In battle, I'll then have to hesitate before drawing upon external energy, risking only consumption without replenishment. If the situation drags on too long, the outcome will surely be dire. Truly a formidable tactic—Eren's Toxic Body is indeed a formidable challenge." With a cold gaze sweeping across the gray-purple mist, Xie Biyan murmured to himself, then, with a subtle mental effort, sealed every pore on his body, enveloping himself entirely in a robust aura of martial energy to effectively isolate himself from the mist. "However, every time the toxic body is fully unraveled, it brings the body closer to its complete eruption. Since you're determined to fight, then I shall join you as well!" With the cold voice落下, a mighty surge of blood-colored energy erupted suddenly from within Xie Biyan's body. Immediately, his two massive claws swung powerfully, his piercing gaze sweeping around the surroundings, ever ready for the hidden young physician to make her move! Due to the isolation created by the gray-purple toxic mist, no one could see the battle unfolding within. Even when Xiao Yan attempted to use his spiritual perception to scan the scene, he would be forcefully ejected from the distorted space. As a result, outsiders remained completely unaware of the battle's progress, able to do nothing but patiently wait for the conclusion of the two combatants' life-or-death struggle. As his gaze slowly shifted back from the gray-purple space, Xiao Yan's expression, though still serious, no longer carried the same level of anxiety as before. Observing Xiao Yishen's earlier actions, it seemed she had also employed something that significantly enhanced her strength. Moreover, her deliberate creation of a sealed, enclosed space in the sky suggested a strong sense of confidence. Given Xiao Yan's deep understanding of her, he knew she would not be foolish enough to deliberately seek her own demise during the battle. "Now I can only wait for the final outcome..." With a soft sigh, Xiao Yan's gaze suddenly grew cold, shifting steadily toward the Scorpion Mountain, his voice slow and steady. "Since the Scorpion Mountain's master has decided to fight me, if today I fail to satisfy you, then I shall indeed have failed in my own expectations." Though his words were calm, the undercurrent of murderous intent was unmistakable—clearly, this persistent obstacle had successfully stirred both his anger and his resolve. Upon hearing Xiao Yan's words, the Scorpion Mountain master's face slightly tightened, then chuckled coldly. "Arrogant youngster! To have me personally face you—this should be a true honor." "Then, by all means, let the Scorpion Mountain master present his head!" Xiao Yan's lips curled into a grim smile. With a solid stomp of his foot upon the void, silver light surged, and his figure surged forward with astonishing speed, leaving several fleeting silhouettes in the sky. In an instant, he materialized atop the Scorpion Mountain, gripping his heavy staff tightly and then delivering a straightforward, unadorned blow to the enemy's head. The massive staff roared with a powerful gust of wind, pressing against the Scorpion Mountain with such force that the latter's robes were tightly pressed against his body. "Hmph!" The Scorpion Mountain snorted, lifting his blue staff with force and meeting the heavy staff head-on without retreating. "Clang!" A sharp, resonant sound of metal on metal echoed as sparks burst forth, and a wave of powerful energy radiated outward from the point of impact, causing both figures to recoil sharply. Xiao Yan rolled through the air, his fiery wings flaring to steady his position. In contrast, the Scorpion Mountain staggered back several steps before finally halting, his hands gripping the staff now trembling slightly. As for physical strength, Xiao Yan was naturally far superior to Xie Shan. Moreover, with the heavy Xuanzhong Chi-Staff and his body refined and strengthened through countless celestial and immortal treasures, Xie Shan's decision to engage him in direct confrontation was undoubtedly the most foolish. Standing steady in the sky, Xiao Yan observed Xie Shan retreating a few steps yet growing increasingly fierce in demeanor. A cold gleam flashed in his eyes, and a surge of vibrant, emerald-hot combat energy erupted from within him, flooding outward toward the heavy staff in his hands. Within just a brief moment, the once-black staff transformed into a lush emerald hue, with slender streaks of emerald flame weaving gently through its length. Feeling the vast energy gradually coalescing upon the profound and heavy measuring rod, Xie Shan's face also tightened. Immediately, he spun his blue staff, sending out waves of rhythmic staff movements, and swiftly circulated his robust battle qi, channeling it rapidly through his meridians into the staff. As the qi flowed in, the blue staff swelled significantly, now appearing more like a towering blue pillar. With this display, it seemed both combatants were employing powerful techniques. The surrounding elite warriors, witnessing this, quickly stepped back, fearing they might be drawn into the action. As the resonant cry echoed within, a vast surge of emerald flame—stretching over a dozen zhang—burst forth from the tip of the staff. The flame swept across, causing the space to tremble, and its intense heat made the surrounding space appear subtly warped. "Thunder Staff!" Seeing the staff's beam surge forward, rich with powerful energy and blazing thermal fury, the Scorpion Mountain warrior gritted his teeth fiercely, then swiftly spun his blue staff. Amidst a brilliant blue glow, the staff moved with an unusual, trembling rhythm, and he drove it squarely into the emerald flame beam. "Boom!" Under the gaze of countless onlookers, the two beams instantly intertwined, and then a thunderous explosion erupted, shaking the heavens. Intense energy surges, mingled with scorching waves of flame, erupted violently from the point of explosion, while the Scorpion Mountain itself trembled, emitting a deep groan under the impact. The palms gripping the blue staff released a hissing trail of white steam, yet Scorpion Mountain clenched his teeth, refusing to let go. With a sudden movement, he hurried to retreat—this time, the strange flame embedded within the beam of his staff had dealt him a significant setback. Within the Scorpion Mountain, the persistent scorching qi is being urgently expelled and refined. Feeling the gust of wind, the ground beneath his feet unexpectedly slips, allowing him to narrowly evade it. After dodging, he steps back again, retreating with a glance toward Xiao Xian, who remains in place and has not pursued. At that moment, he intends to sneer, yet as the sneer forms in his throat, a sudden, petite figure appears behind him. Immediately, a clear, crisp voice resonates. "Clap! I'll give you a punch!" As the youthful, bright voice finishes, a fresh, pale fist bursts forth, glowing with vibrant purple light, a formidable force concentrated within it. Feeling the sudden surge of terrifying power behind him, a shock of astonishment appears in the Scorpion Mountain's eyes. He forcefully turns around, raising his blue staff to shield his chest. "Boom!" The small fist struck squarely against the blue staff, yet before Scorpion Mountain could even exhale a breath, a sharp crack resonated, leaving him chilled to the core. There, the staff—no weaker than refined iron—had suddenly snapped in two, while the small fist merely skimmed past, finally landing upon its chest.
