Suddenly, the intense cold and deadly aura pouring from the sky caused many people's faces to change. Though they didn't know exactly what had happened, it was clear from Han Feng's demeanor that he now truly harbored a decisive intent toward Xiao Yan. Su Qian swept her robe, sending the two elder masters—like wolves charging forth—reeling backward. She turned her gaze toward the young man in black robes in the distance, her eyes briefly flashing with an unusual expression: "This feeling...". "Xiao Yan, hold on for a moment. I'll take care of these two elders and come to your aid shortly," Su Qian said, her eyes flickering briefly before settling into calm confidence. Her hearty laughter echoed across the sky. "Heh, Elder Qian, just focus on handling them—Xiao Yan hasn't been that fragile, has he?" Xiao Yan bowed gracefully and smiled warmly. "Heh, it's impressive—everyone underestimated you, little one." Smiled with deep significance. A surge of qi poured forth from Su Qian, overwhelming and vast. Then, his face grew cold as he gazed at the two elders—Jin and Yin—whose expressions were grave. With a cold laugh, he moved swiftly, like a ghost, charging forward with relentless intensity. Seeing such a fierce assault, the two elders could not afford to slacken, and promptly joined forces to meet the attack. Turning his gaze from Su Qian, Xiao Yan sneered at Han Feng, who stood across from him with a determined, murderous expression. With a flick of his fingers, a streak of emerald flame danced gracefully before him, like a sprite playing about. Gazing at the flame, he chuckled lightly, "Do you really intend to kill me?" Han Feng's face tightened, struggling to hold back the urge to charge straight ahead and eliminate Xiao Yan. His voice came out dry and strained, "How—how did you acquire this technique?" Xiao Yan smiled, still without answering. At that very moment, the profound spiritual energy suddenly surged into his body. As it entered, Xiao Yan clearly felt his ability to control his power surge even further. "Master... you?" The sudden change left Xiao Yan momentarily stunned. With the old doctor channeling all his strength into him now, wouldn't the opposing Han Feng notice something amiss? "He'll eventually realize it," said the old doctor with a calm, gentle laugh in Xiao Yan's mind. "Well, then, let him have a little surprise." The tone at the end, however, carried a subtle chill. After a brief pause, Xiao Yan nodded and raised his hand seal, fully releasing his suppression of the vast spiritual energy, allowing it to fully merge within his own body. As the old doctor's spiritual energy fully flowed into Xiao Yan, the vibrant green flames surging over his body grew increasingly lively, swirling rapidly and emitting steady, rushing sounds. Xiao Yan's sudden surge of power also caused Han Feng's expression to subtly shift, his gaze fixed tightly on the former. After a moment, his body suddenly trembled, as if sensing a familiar force rising within the swirling emerald flames. His mind swiftly searched through memories, and finally settled on a vivid image of an ancient, weathered figure deep within his recollection. Instantly, a wave of shock and panic surged from the depths of Han Feng's heart, reviving the long-forgotten memory before him, causing his entire body to shake violently. The previously stern, resolute face now turned an unusual pale white. Han Feng stared in wide-eyed terror at Xiao Yan, and only after drawing upon every ounce of strength did he manage to utter a voice trembling with profound astonishment and fear: "You... you're not dead?! How is that possible?" Xiao Yan gazed at Han Feng, whose face had suddenly turned pale, with a calm expression, and said, "Thanks to you, I've met my master. Otherwise, my journey of cultivation would have lacked many thrilling moments." "Master?" Han Feng's eyes narrowed slightly, fixing his gaze on Xiao Yan without blinking. The initial pallor on his face slightly faded, and as his eyes flashed with intensity, a deeper sense of hostility emerged. The news of Yao Lao's survival had struck him like thunder. As one of Yao Lao's former disciples, he was well aware of the master's immense influence across the continent. Even today, the true peak cultivators still remembered the legendary "Master of Medicine" who once dominated the land. Han Feng had no doubt that if word spread of Yao Lao's continued life, countless peak-level cultivators would come to hear it. Moreover, most importantly, the Elder of the Medicine Sect enjoys exceptional popularity among the peak-tier strong ones. For instance, the Wind Master, who owes him a life-saving debt, has remained steadfast in his search for the Elder's traces despite his prolonged absence. On several occasions, he even investigated Han Feng, yet found no solid evidence—thus, he was ultimately powerless against Han Feng. Yet now, the Elder has not faded away as Han Feng had anticipated, but rather has survived. Han Feng cannot imagine what predicament he would face if the Elder revealed the hidden treachery he once orchestrated—how then would he be able to withstand the wrath of the Wind Master, a legendary master of the Du-Respect rank? Even Han Feng himself, at present, would hesitate to dare to challenge him. As his thoughts shifted, Han Feng's expression waxed and waned, eventually settling into a fierce, cold resolve—only by making Xiao Yan and Yao Lao forever silent could he ensure his own survival, and in that case, the dead would be the most trustworthy. With a surge of murderous intent, Han Feng suddenly lifted his head, like a venomous serpent coiled in the shadows, his voice hoarse: "Old man, whether you live or die, today I will have you both completely silent!" "Hehe, I never realized you were so strong—thanks to the soul power of that eternal old man. But I didn't expect the 'Burned Decree,' which I pleaded for year after year and he still wouldn't pass on to me, to end up in the hands of someone so young like you. Did he really think you'd surpass me?" Han Feng smiled calmly, his voice tinged with an unmistakable sense of envy and resentment. Xiao Yan raised a faint, quiet smile, saying nothing further. "If he had passed the Burned Decree to me back then, I would have still held him in the highest regard. But—how could he blame his own eyes? Does he not see my potential?" His cheeks flushed slightly, and his emotions seemed stirred. He had always believed that if Master Yao had granted him the Burned Decree, the scene today would have been entirely different. Had Xiao Yan not heard Han Feng's strained, forceful roar, the cold, murderous intent in his black eyes would have only grown deeper and more piercing. Suddenly, the swirling jade flames above Han Feng's head surged downward, coalescing into a massive jade sphere at the right palm of Xiao Yan. Then, slowly, Xiao Yan extended his left hand—finally, as Han Feng gasped to a sudden stop and stared in awe, he summoned a cluster of pale, crisp flames. Two distinct flames intertwined, creating an unusual temperature that spread throughout the heavens and earth. At their point of contact, filaments of flame shimmered like electric sparks, and as the two flames collided, the very space around them trembled. Temporarily setting aside his jealousy and fury, Han Feng, even with his vast experience, found himself struggling to comprehend Xiao Yan's actions—did he not know of the inherent incompatibility between these two types of flames? Though puzzled, he did not remain passive. With a firm grip, he swiftly gathered his deep blue flame, which rapidly coalesced into a solid, tangible trident of deep blue hue. Holding the flame trident, over two zhang wide, Han Feng felt his confidence grow once more. His gaze remained cold and sharp upon Xiao Yan, who was diligently attempting to control the two divergent flames: "Old man, I know you're within him. But today, I'll make sure you have no chance to escape!" As the words settled, a magnificent surge of intense emerald flame erupted suddenly from Han Feng's body, spreading out in all directions like a vast oceanic wave. The flame roared and surged, crashing down like a tidal wave, ultimately fully pouring into the flaming trident. This overwhelming influx of flame caused the trident to instantly expand several zhang in length, with vibrant deep-blue flames swirling ceaselessly upon its surface, and the thunderous sound of waves crashing against one another echoing continuously. "Younger brother, I've instructed Master to have you and Teacher buried here together!" The massive trident hovered above Han Feng's palm, and as he felt the immense power within it, he couldn't help but move his lips slightly, his voice thin and cold, carrying clearly into Xiao Yan's ears. Xiao Yan slightly raised his brow, his eyes still focused on the intertwining hetero-flames in his hands. Suddenly, his gaze sharpened, and with a firm press of both palms, the two hetero-flames that had hesitated to merge finally reached a remarkable balance. Thereupon, an brilliant, intense light erupted from between them, shining like the sun itself and drawing everyone's attention. The sudden brilliance caused many to turn their gaze toward the scene. After a moment, the light dimmed, and the vivid image within became clearly visible. Above the sky, a young man in black robes stood suspended in the air, a large, pale-green lotus flower—two feet wide—floating gently in the palm of his hand. This lotus, though unremarkable compared to the deep-purple flame lotus previously displayed by Xiao Yan, appeared more restrained and subdued, emitting barely any visible energy. Yet, those with keen eyes would notice that as the lotus slowly rotated, the space around it subtly warped and distorted. While ordinary observers might not perceive its grandeur, the three elders—Su Qian, and the two elder masters—engaged in a fierce battle somewhere in the heavens, suddenly ceased their combat movements in unison, turned sharply to face Xiao Yan, and all their eyes were fixed upon the pale-green flame lotus resting in his palm, filled with an unmistakable sense of awe and fear. The power radiating from it—was even enough to instill such profound fear in them!
