Within the ancient altar, beams of light poured down from the heavens, materializing as tangible rays that settled upon the altar, bringing a warm, soothing sensation. Xiao Yan sat nestled among the interwoven beams, glancing at the young physician before him. Now, the latter no longer emitted a single trace of toxic energy; the once pale complexion, weakened by her affliction of toxic body, had regained a healthy, rosy hue. Clearly, the body that had long suffered under the relentless assault of toxins was now beginning to revive and flourish once more. Xiao Yan’s gaze swept briefly and then settled upon the smooth, even abdomen of Xiao Yi, where a vast surge of energy now surged forth. Even though he was separated by her body, he could clearly sense the immense power, and it was visibly contracting toward the center at a steady, observable pace. As this contraction unfolded, the bare elegance of Xiao Yi’s form radiated a gentle luminescence, like warm jade—distantly, she appeared as a celestial maiden, exuding a sense of sacred purity. After a brief glance, Xiao Yan lowered his eyes. Ordinary people could hardly imagine the irresistible allure of such purity, revealed so effortlessly and unguarded—much like a goddess in their hearts suddenly displaying her most graceful and captivating form, radiating an immediate, compelling charm. After a while, even with his eyes fixed on his nose and his nose focused on his heart, Xiao Yan still found it difficult to concentrate. He chuckled softly, withdrawing a large, flowing robe from his meditation vest, and gently covered the slender form of Xiao Yishen. As a normal man, he thought, such persistent allure was better kept to a minimum—too much of it, and it might drive one to psychological distress. Once these gestures were completed, Xiao Yan felt a great sense of relief. He glanced around, and the beams of light reflecting off the smooth stone walls caused his eyes to slightly blur. Seated on the altar, it felt as though he were immersed in a world bathed in sunlight—like the altar itself had become a radiant sun, and they all existed within its golden embrace. Currently, Xiao Yishen’s condition had stabilized and was progressing steadily. As long as she successfully compressed the adverse toxic energies into the magical core, the toxic elixir would fully form. During this process, Xiao Yan could offer little assistance—only her own strength and determination would matter. Though he had nothing directly to do here, Xiao Yan naturally couldn't leave now. He had to stay until the Little Doctor of Medicine completely solidified the toxic pill, only then could he feel at ease—after all, he hadn't much experience with this method of toxic pill cultivation. "The fire-energy within this ground-eye is indeed remarkably robust..." Xiao Yan stroked his chin, not entirely sure why the ground-eye wasn't now spewing out those core-earth flames. Yet he did have a certain interest in this phenomenon—particularly in the yang-fire emanating from the altar. After a moment of contemplation, Xiao Yan suddenly lightly pressed his palm against the ground-eye and issued a soft cry, causing a powerful suction to surge forth from his palm. As the suction intensified, numerous fire-energy streams were pulled out of the ground-eye and dispersed around it—but the much-anticipated core-earth flames still failed to appear. Seeing this, Xiao Yan furrowed his brows, then scoffed, truly unconvinced that no core-earth flames could be drawn at all. With renewed determination, he sharply intensified the suction, and streams of rich, vibrant fire-energy continuously rose from the ground-eye—but the core-earth flames remained absent. This intense suction force lasted nearly fifteen minutes. As Xiao Yan began to feel utterly overwhelmed, his mind suddenly stirred, and he swiftly moved his hand. With his hand shifting, a slender, delicate streak of crimson flame burst forth from within the earth's fissure. As soon as this streak of flame emerged, it immediately collided with the beams above it, causing a ripple of energy. A soft "pff" sound echoed, and suddenly, a warm, white flame materialized before Xiao Yan. Xiao Yan stared in astonishment at this flame. Though white, it was threaded with countless fine crimson veins, resembling blood vessels that branched out throughout the flame, forming an intricate network. "Is this the Yang Fire?" Xiao Yan gently extended his hand and received the ball of white flame. The energy within was remarkably calm, lacking the wild intensity of other flames. Yet, with his keen eyesight, he could see that this Yang Fire was significantly stronger than ordinary beast fires—though it lacked the raw fury, its attack power might not be overwhelming, it was exceptionally well-suited for alchemy, as it was easier to control. "I wonder if this Yang Fire can serve as nourishment for the flame seed of my Nong Yan Ju technique," Xiao Yan mused, gazing at the white flame. At present, his Hua Sheng Fire was still in its infancy and far from sufficient to support the full manifestation of his Sheng Huo Lian. If this Yang Fire could also serve as a nourishing element for his Hua Sheng Fire—just as beast fires did—then it would indeed be a fortunate gain. With this thought forming, Xiao Yan hesitated not at all. He simply grasped his palm, drawing the ball of yang fire directly into his body. Then, the ruyi lotus fire surged forth, effortlessly refining and integrating the yang fire into the delicate seed of his innate fire within. "Indeed effective..." As the yang fire merged with the fire seed, Xiao Yan clearly sensed the seed expanding significantly—far more than when absorbing ordinary beast fires. Observing the remarkable effect of the yang fire, a gleam of satisfaction passed through his eyes. Unlike beast fire, which was often difficult to tame, this yang fire proved easy to refine and cultivate. Should sufficient quantities be gathered, it would surely nurture and strengthen the innate fire seed. Thinking of the future, when the innate fire seed would grow robust, and thus his destruction fire lotus would have ample medicinal support, Xiao Yan felt a warmth spread through his heart. His gaze suddenly sharpened toward the ground eye before him. With a chuckle, he extended his hand once more, and the suction force surged powerfully! This suction lasted over twenty minutes, and only gradually did a slender streak of blood-red flame emerge from the earth's eye, merging slowly with the yang fire before being entirely swallowed by Xiao Yan in one breath. Enriched by this delightful experience, Xiao Yan grew increasingly enthusiastic, repeatedly drawing out the earth-core flames from the earth's eye. However, this method was clearly not sustainable—the earth-core flames within the earth's eye had already dwindled to near exhaustion. After several strong withdrawals, they finally ceased to appear, leaving Xiao Yan drenched in sweat, yet with no further flame spilling forth. "Could it be that they've truly been completely drawn out?" Wiping the sweat from his forehead, Xiao Yan furrowed his brows, gazing at the motionless earth's eye, and murmured with growing frustration. After pondering for a while, Xiao Yan suddenly closed his eyes slightly, allowing his vast spiritual power to gradually radiate out from his brow, then thinning into a single thread that shot swiftly toward the earth's eyes. As Xiao Yan's spiritual energy entered the earth's eyes, he immediately felt a sense of warmth. Fortunately, his spiritual essence was protected by the Strange Fire, so this warmth had not yet caused any harm. As Xiao Yan's spiritual essence delved deeper, the warmth grew stronger and stronger. Eventually, even with the protection of the Strange Fire, he began to feel a subtle dizziness. Noticing this dizziness, Xiao Yan felt a sudden surge of alertness. Deep within the earth eye, there was an exceptionally potent fire toxin—so potent that even his soul was being eroded by it. Upon realizing this, Xiao Yan hesitated, for the earth eye was too deep to penetrate fully. Should he be unable to return, though he wouldn't face immediate mortal danger, his soul would surely suffer damage. As he deliberated whether to withdraw his soul energy, a sudden flash of red light emerged from the deepest part of the black earth eye. "Hm?" The red glow caught Xiao Yan's attention, and he was momentarily surprised. After a brief pause, he decided to send his soul energy toward the point of light. His soul energy moved swiftly, and within moments, the red glow appeared clearly within his soul vision. The crimson glow emanated from a thick, viscous blood-red liquid of unknown origin, forming circular shapes that precisely sealed off the earth's fissure. "Such astonishing fire-based energy…" As his eyes first fell upon the viscous, almost solid liquid, Xiao Yan drew in a sharp breath. This liquid, seemingly solid, was composed entirely of coalesced pure fire energy. "It makes sense that the earth's core flames can no longer surge forth—they've all been completely blocked here…" Xiao Yan had a moment of realization upon seeing the liquid, yet he didn't immediately plan to clear it. The energy contained within was so turbulent that even a slight disturbance could trigger a cascade effect; should anything go wrong, the soul energy might never escape the fissure. After a moment of contemplation, Xiao Yan decided to set the matter aside and simply proceed to leave. Yet, as he turned to depart, he suddenly noticed a flicker of red light emerging within the crimson liquid. "What is this?" Xiao Yan's soul gaze followed the crimson light, and suddenly, he saw a round, blood-red orb floating within the thick, crimson liquid—about the size of a thumb. Though not large, the orb appeared remarkably magical, glowing like a flame burning steadily. Xiao Yan's soul gaze remained fixed on it, stunned, for a long while, before finally taking a deep breath. "The Heart-of-the-Earth Pearl?"
