At the very instant the thunder roared, Han Feng's face turned pale. It wasn't until now that he realized—he had been so captivated by the allure of the Falling Heart Flame that he had completely forgotten about the formidable enemy watching him from afar. As his expression shifted, Xiao Yan had already materialized like a ghost behind him, his five fingers clenched tightly. Seething with vibrant blue flame, the flames danced continuously on his palms, eventually merging with a scorching gust of wind that slammed hard against Han Feng's back. Feeling the sharp, piercing wind laden with deadly intent behind him, Han Feng intended to dodge—but due to the internal suppression of his Heart Flame, his mobility and reflexes had been significantly hampered. When his evasive attempts failed, it seemed he could only wait passively for the attack to arrive. The stronger the wind drew nearer, the tighter it pressed against Han Feng's robe, pressing it firmly against his back. Yet, just as Xiao Yan had thought Han Feng was merely waiting passively, a sudden surge of fury flashed across his eyes. His shoulders shook violently, and a deep blue flame erupted violently from his shoulders. Han Feng's ability to simultaneously defend was indeed surprising to Xiao Yan, though it did not cause him to hesitate for a moment. The wind pressing against his fists grew stronger, intensifying as it surged forward, cutting straight through the deep blue flame and striking Han Feng squarely on the shoulders. The powerful force erupted at the point of contact, propelling both figures—both of whom had sustained injuries—backwards in a violent arc, tracing nearly fifteen meters through the air before gradually coming to a halt. Brushing aside the slightly torn fabric on his chest, Xiao Yan's expression remained largely unchanged. Though the attack appeared fierce, it had been a last-minute counterstrike from Han Feng, merely causing a slight discomfort in his chest. In contrast, Han Feng, who had been struck squarely and unexpectedly by Xiao Yan, looked visibly unsettled. Though he had narrowly avoided Xiao Yan's critical blows at the final moment, the fierce gust of wind emanating from his fists still left him with a numbness in half of his shoulder. In the sky, the figures enveloped in jade and sapphire flames stood face to face, each bearing a hint of unyielding, sharp hostility in their eyes. Glancing sideways at the chaotic battle unfolding in the sky, Han Feng slightly furrowed his brows. With time running short, he couldn't afford to be held up by this young man for too long—otherwise, once the strong members of Ganlan Academy were free to act, the difficulty of securing the Fallen Heart Flame would surely increase even further. Han Feng smiled warmly and said, "So, right now, this Fallen Heart Flame holds little value for you, young sir. If you're willing to give me a favor, I can trade you my sixth-rank pill recipe in return—how does that sound?" Hearing Han Feng's words, Xiao Yan's faint scorn widened into a full-blown cold smile. He gently shook his back, where the emerald flames fluttered, and coldly remarked, "Since you know that alchemists can't coexist with two distinct flames, why not give me this chance instead?" His expression slightly shifted as he listened to the tone in Xiao Yan's voice. Han Feng realized that the chances of persuading him were nearly nonexistent. With that, he gradually smoothed out his smile, raised his hand, and gazed steadily at the deep blue flame dancing playfully above him. He said calmly, "Very well. Then I shall... take your unique flame as well!" As the final syllable fell, the deep blue flame enveloping Han Feng suddenly burst forth, and a spectral figure darted like lightning toward Xiao Yan, its fierce gusts and killing intent spreading silently across the sky. "I've also always been interested in your unique flame—right now, it's still unclear who's going to claim it!" Though Xiao Yan had been fully focused on Han Feng, he sensed the sudden shift as Han Feng's form flashed past. With a cold laugh, Xiao Yan's feet resonated with thunder, and he too vanished instantly—reappearing moments later, now in direct confrontation with the spectral figure. "You're quite arrogant, young man! When I first gained fame across the continent, you were still nursing your first milk!" Observing Xiao Yan's unyielding stance, Han Feng coldly smiled, his deep blue flame surging violently from within and swiftly gathering into his palms. The flames rose in cascading waves, layer upon layer, so vivid and real that upon closer inspection, they appeared as genuine ocean waves, leaving the onlookers utterly awestruck. "I'd like to find out—whether it's your Qinglian Earth-Heart Flame that's superior, or mine, the Sea-Heart Flame, that truly outshines!" With a sharp cry, Han Feng suddenly thrust his palms forward, and the intensely concentrated deep-blue flame at his palm erupted with the roar of a surging sea tide, crashing toward Xiao Yan with thunderous force. This was his true finishing move—clearly, in his haste to save time, Han Feng had completely abandoned any intention of conserving his strength. "Watch out! This is an unusual fire taking on form—its shape and intensity have been solidified, making it exceptionally powerful!" The elderly pharmacist's serious and urgent voice suddenly echoed in Xiao Yan's mind, causing him to slightly shift his expression. Gazing intently at the vast wave of deep-blue flame sweeping toward him, Xiao Yan felt as though he were a solitary boat adrift in an endless ocean. Drawing in a deep breath of scorching air, every drop of Qinglian Earth-Heart Flame he could summon surged forth from within him at that very moment. As the Qinglian Earth-Heart Fire surged forth continuously, the flame gathered at Xiao Yan's head grew increasingly emerald. Within a few blinks, the flame suddenly began to quiver strangely. A moment later, a complete, emerald-colored lotus, entirely formed of Qinglian Earth-Heart Fire, materialized. This emerald fire lotus shimmered with the clarity of jade, with streams of liquid resembling emerald magma flowing through it, radiating splendid beauty. A surge of vivid blue flame, intermingling and sweeping out in all directions, crashed over the battlefield with overwhelming force. Where the flames passed, even the lofty clouds above were shattered into scattered specks of pale white, scattered across the sky. The sudden, terrifying surge of energy in the heavens momentarily silenced the chaotic battlefield. As people felt the immense power contained within the waves of flame, many quietly gasped—this was indeed the destructive power of colliding hetero-flames. Truly awe-inspiring. Although Xiao Yan appeared disheveled, Han Feng far from fared any better—his robe torn, his hair wild, breathing heavily. Yet at this moment, he paid no attention to his own state, his eyes filled with shock and disbelief, fixed on Xiao Yan as if he had seen a ghost. Gazing at Han Feng's comical appearance with a steadily glowing gaze, Xiao Yan couldn't help but smile, the bright whites of his teeth sending a chill down Han Feng's spine. "Have you noticed?" he asked. With trembling fingers pointing at Xiao Yan, Han Feng gasped and wheezed, struggling to speak for a while before his voice finally rose in a sharp, hoarse cry echoing across the sky: "You—you—you've been practicing what kind of cultivation technique? Tell me! Tell me now—or I'll kill you!" The chaotic battle in the sky had momentarily halted due to the intense clash between Xiao Yan and Han Feng. Now, witnessing Han Feng suddenly going berserk, everyone present stared in quiet astonishment, utterly at a loss. Gazing at Han Feng's seemingly frenzied state, Xiao Yan merely smiled—his smile bright and warm, yet carrying a coldness that chilled the very soul. "Don't you realize?" This phrase, which sounded odd to others, struck Han Feng like a revelation. His pupils instantly shrunk to pinpoints. The unease he had long concealed within himself began to spread throughout his body. Thanks to the fierce collision they had just endured, he now sensed that Xiao Yan's cultivation technique bore a striking resemblance to his own—indeed, upon closer inspection, Xiao Yan's method was even purer and more orthodox. Yet, at the very moment he had clashed with Xiao Yan, he clearly sensed that the other's cultivation technique was purer and more authentic than his own! A technique more refined and orthodox than the fragmented "Burned Decree"—such a technique existed in the world only once. That was the complete version of the "Burned Decree!" At that instant, a surge of fierce, uncontrollable murderous intent erupted within Han Feng's heart, directed solely toward Xiao Yan.
