Above the horizon, after striking Han Feng and sending him plummeting, the Fallen Heart Flame unexpectedly did not pursue him further. Instead, it swiftly turned its massive head, its serpent-like eyes locking onto Xiao Yan at a distance. At the very instant the Fallen Heart Flame focused on Xiao Yan, the Qinglian Earth-Heart Fire within it seemed to sense a warning and suddenly surged forth, erupting in a surge that instantly enveloped Xiao Yan completely. "Keeee!" The formless fire serpent emitted a sharp, piercing cry, then violently whipped its massive tail. With the powerful, scorching gusts of wind rushing forward, the colossal body surged toward Xiao Yan at high speed. Observing the fire serpent, which had so decisively shifted its target, Xiao Yan quickly flapped his back wings of emerald flame. Silver light shimmered beneath his feet, and in the sound of a soft, distant thunder, he vanished like a ghost from the scene. The colossal tail swept across the spot where Xiao Yan had previously stood, and wherever the terrifying surge of energy passed, the very air erupted with deep, resonant booms. Unsatisfied with the first strike, the formless fire serpent turned its gaze and swiftly spotted the black figure materializing in the sky beyond a hundred meters. A cold, ominous glint flashed in its vast serpent eyes, and then a surge of intense, formless flame rapidly surged from within its body. Instantly, the massive figure of the formless fire serpent vanished once more into the flames—this time in a most peculiar manner. Watching the formless fire spirit vanish so strangely, Xiao Yan was momentarily stunned. Yet, thanks to the precedent set by Han Feng earlier, he could already vaguely deduce that the true form of Yunluo Xin Yan had transformed into ordinary flame, now concealed within the vast, sweeping tide of formless fire. "Be careful not to be engulfed by those flames. As a pure hetero-fire, the Falling Heart Flame can freely transform into a cluster of flame and then coalesce back into its original form upon reaching your vicinity to launch an attack." The serious voice of the Herbal Elder echoed promptly in Xiao Yan's mind. Upon hearing this, Xiao Yan stiffened, nodded slightly, and gazed at the invisible flames sweeping in from all directions. His back wings of azure fire flared once, and as the surrounding flames had not yet formed a solid network, he slipped through a gap and emerged. Immediately after stepping out of the flame enclosure, Xiao Yan sensed a strong surge behind him. A quick glance to his side revealed that an invisible flame had suddenly rippled—within it, the massive body of the fire serpent appeared and faded in and out. "Crick!" A sharp, piercing roar suddenly erupted into the heavens, and an intangible fire serpent coalesced from a pool of flames. As it fixed its gaze upon Xiao Yan, who had broken free from the encircling formation, a deeply human-like fury flared in its serpentine eyes. With its massive, grotesque jaws opening wide, a surge of invisible flame erupted directly toward Xiao Yan. Suddenly lifting his head, Xiao Yan took a deep breath of cool air. The clear sky was now occupied by waves of intangible flames, floating around the invisible fire serpent, like soldiers poised for immediate attack. "Crick!" A sharp, piercing cry rang out, followed by a surge of flames that swept across the heavens. Everyone could only stare in awe at the invisible flames plummeting down like meteor stones, their continuous, rushing sound filling the air and creating a sense of impending doom. Amidst this overwhelming assault, even with the strength of Yao Lao supporting him, Xiao Yan could not help but feel his heart race. Compared to this fire, which had accumulated over countless years, human power truly seemed frail and vulnerable. "This beast's energy appears inexhaustible. With this relentless barrage of attacks, it will eventually wear it down. Damn it—I must find a way to seriously wound it!" With his fists clenched, sweat rolled down Xiao Yan's face like a steady stream, his eyes fixed intently on the intangible fire serpent soaring in the sky. Though his strategy was sound, how could he possibly deal a serious blow to the Fallen Heart Flame? The earlier attack by Han Feng—so powerful and forceful—had not only failed to wound it significantly but had even enraged it, leaving Xiao Yan himself exhausted and suffering. "Stay calm," the old medicine master's low voice suddenly resonated within Xiao Yan's mind. "What you see now is merely the outward form of the Fallen Heart Flame. Its true essence lies concealed somewhere within this vast body. As long as you locate that essence and strike it directly, the Fallen Heart Flame will inevitably suffer a severe blow. If you continue to attack randomly, as that man has done, you'll only be wasting your strength!" Shaking all over, Xiao Yan nodded firmly, biting his teeth, and slowly exhaled. The previously restless heart gradually calmed down. The flames surged across the sky, as if heralding the end of the world—so terrifying was the scene that many people found their legs trembling. "Whoosh! Whoosh!" Like meteorites, the flames roared with a continuous burst of rushing air and scorching wind, plummeting from the heavens. Above, Su Qian and the others watched the massive, near-catastrophic assault unleashed by Xun Xin Yan, their faces instantly pale. Should this attack strike the inner courtyard, every building would be reduced to ashes in moments. The flames illuminated Xiao Yan's face, where sweat glistened. In his dark pupils, streaks of flame rapidly approached. Under the overwhelming wind, his black robe was pressed tightly against his skin, its once soft fabric now dry and brittle, as if drained of all moisture—so delicate that a single touch might turn it into powder. At this crucial moment, Xiao Yan's spirit was intensely focused, his eyes firmly locked onto the countless flaming meteorites crashing down around him. Suddenly, without realizing it, the various noises from outside quietly faded into the background. Within those clearly defined eyes, there seemed to remain only the trajectories of the falling flames and the immense entity at the source of the fire. The flame in his eyes rapidly faded, and Xiao Yan's gaze once again cleared. A subtle silver glow on his feet gradually intensified, and crisp thunder rolled steadily across the sky. Then, with a sudden leap, Xiao Yan's foot surged forward—leaving behind a clear afterimage. Unparalleled speed caused the world around Xiao Yan to blur, yet at the far edge of his vision, the intangible essence beneath the great fire serpent's massive maw remained brilliantly clear and distinct. "Roar!" As the distance between the two closed in, a deep, thunderous roar erupted from Xiao Yan's throat. He clenched his hands, and the jade-colored flames surged like lively spirits, swiftly solidifying into a towering lance of searing jade fire. With a single footstep into the air, lightning flashed and his afterimages lingered. Under the unwavering gaze of countless onlookers, a faint, indistinct silhouette materialized in an instant before the intangible fire serpent. In close proximity to the great serpent, its immense form evoked a profound sense of smallness. Under the weight of its vast, ancient eyes, a sense of awe and reverence filled every observer. "Creature, die!" "The scorching temperature caused searing pain throughout Xiao Yan's body, yet his hands remained firmly gripping the flame lance. A sharp cry rang out, and the massive lance surged like a lightning bolt tearing through space, swiftly and powerfully piercing the serpent scale beneath the fallen heart flame's massive maw. 'Stupid boy—just asking for it!' On the ground, Han Feng watched Xiao Yan daring to approach the fallen heart flame so closely, and couldn't help but sneer. Having faced him in direct combat, Han Feng was well aware of the creature's formidable strength—his own earlier strike, which had condensed the unique fire, had failed to make an impact, let alone Xiao Yan's. Many others shared Han Feng's thoughts, even Su Qian's expression grew slightly more serious, his inner qi flowing steadily, ready to intervene at a moment's notice." Yet, as the crowd chuckled and grew anxious over Xiao Yan's bold, impetuous move, the intangible flame serpent pierced by Xiao Yan suddenly lifted its immense head, emitting sharp sonic waves laced with unmistakable pain, resonating fiercely across the sky! As the piercing cry rang out, the serpent's form began to grow ethereal, gradually fading into a shimmering, translucent presence under a cascade of stunned gazes. "Perfect strike!" Liang's laughter suddenly echoed in Xiao Yan's mind—warm with both satisfaction and excitement.
