A fierce wind roared past his ears, carrying Xiao Yan's body continuously sliding downward along the cave entrance. As his form drew nearer to the subterranean world of molten rock, the surrounding air grew increasingly scorching. A faint emerald flame seeped out from within Xiao Yan, isolating the external heat. Gazing down at the pure, deep crimson glow below, he took a steady breath, a quiet sense of caution rising within him. This place wasn't one for leisurely exploration—there must be numerous dangers. Caution, he thought, would always be safe. The subtle sense of summoning he had felt earlier had faded into nothing after only a brief moment, and this strange occurrence made Xiao Yan question whether it had been merely his own perception. This relentless descent continued for a while, and only then did Xiao Yan's vision suddenly broaden. Before him now lay an endless world of molten rock. Massive bubbles rose from the lava, burst, and released a scorching aura accompanied by wisps of white vapor. These vapors carried a subtle fire toxin; if inhaled, they would pose a significant issue. Xiao Yan stirred his spirit, and his crystalline bone wings gradually unfolded from his back, gently flapping to stabilize his body, suspending it gracefully within the molten world. His body suspended in midair, Xiao Yan carefully scanned the surroundings. The volcanic world remained as silent and lifeless as it had been when he had left—no signs of life, only the faint, delicate sounds of bursting magma bubbles echoing through the stillness. The magma here was notably thick, rarely forming waves or ripples. Everything about this place exuded a heavy, oppressive stillness. Over time, one might even find their personality growing increasingly odd and reserved. Fortunately, Xiao Yan had been in a state of apparent death, completely unaware of the outside world. Otherwise, those years would have been quite unbearable. At this point, Xiao Yan felt a sense of relief. After a brief inspection and finding nothing amiss, he vibrated his bone wings and approached a cliff wall, drawing out the Xuanzhong Scale. Emerald flames spiraled upward, and under the intense heat of the Lirui Lotus Heart Fire, the solid cliff wall softened as if it were tofu. With rapid wrist movements, stones flew in all directions, and within moments, a spacious opening measuring a zhang in width appeared on the wall. Thanks to the high temperature of the Lirui Lotus Heart Fire, Xiao Yan effortlessly created a small mountain cave suitable for rest on the cliff wall. After completing this, he did not immediately descend into the molten lava to practice the "Liù Hé Yóu Shēn Scale." Instead, he settled cross-legged inside the cave, gradually closing his eyes and entering a state of meditation. As Xiao Yan entered his state of cultivation, the space around him surged violently, and a visible wave of crimson energy poured forth in overwhelming abundance, rushing in eagerly to fill his body. At the moment these crimson energies entered his body, Xiao Yan's slightly closed eyes suddenly snapped open, a mixture of joy and seriousness flashing across his gaze. The abundance of energy here indeed exceeded his expectations, but the fierce, turbulent nature within it was equally surprising. Should he absorb too much of such turbulent energy, it might subtly alter one's temperament—something Xiao Yan could not tolerate, even though accepting it would undoubtedly accelerate his cultivation progress beyond ordinary levels. "Good thing I was well-prepared..." After a brief pause, Xiao Yan smiled, flicked his hand, and a delicate green flame rose gently, eventually fully enveloping his palm. A flame appeared. With the other hand, Xiao Yan curled his fingers and lightly snapped them, causing several items to materialize before him, which then floated mid-air under his control. All of these items were medicinal herbs, radiating a noticeable coolness—clearly herbs infused with ice or water energy. Xiao Yan glanced at them casually, then waved his hand, and all the cold-natured herbs settled into the palm of his hand. Now, he was a genuine Sixth-Rank Alchemist, capable of mastering the art of crafting ordinary pills with the same ease as the old pharmacist had once done—his palm forming a furnace, allowing him to work with effortless precision. Under the control of Xiao Yan's spiritual power, those several cold-natured herbs were swiftly transmuted, and a viscous, white liquid of night's chill gradually emerged. This time, Xiao Yan was not preparing a pill, but rather crafting a supplementary item for cultivation—much like the small items crafted by the Elder of Medicine during his early expeditions. Thus, it did not take him much time; within just ten minutes, all impurities within the cold liquid were thoroughly expelled. The translucent, clear liquid swirled gently within the flames. Xiao Yan flipped his hand, and a small jade bottle appeared in his grasp. Tilting the bottle's mouth, a stream of crimson blood, tinged with cold, flowed out and dripped into the flames, where it merged seamlessly with the cold liquid. As the two elements blended, the color subtly shifted. Subsequently, under the gradual heating of the crystal lotus heart flame, the mixture solidified into a smooth, pale, viscous liquid, from which delicate strands of chill radiated outward, effectively countering the surrounding intense heat. Upon witnessing the successful refinement, the jade-green flames on Xiao Yan's palm gradually faded. With a simple finger motion, the pale, viscous liquid settled into a jade vial. After completing this, Xiao Yan swiftly removed his garments and laid the entire body of the cold liquid upon his skin, ensuring every inch of his body was fully covered. As the cold liquid touched his skin, an immediate sense of coolness enveloped him, swiftly transforming his previously warm skin into a refreshing chill. Even Xiao Yan could not help but shiver under this intense cold. Seizing the moment when the chill was at its peak, he once again settled into a meditative posture, entering his state of cultivation. As Xiao Yan had just entered his cultivation state, the surrounding intense fire-energy immediately surged toward him once again, as though drawn by an unseen force. This time, when the tangible, crimson energy struck his body, it collided with the layer of cold liquid coating him. The intense heat and the icy cold clashed, and the medicinal potency embedded within the cold liquid swiftly neutralized the turbulent energy of the heat, then fully infused the purified energy into Xiao Yan's body. Xiao Yan gazed intently at the surging waves of scorching energy, sensing the fading, almost imperceptible surge of wild turbulence within it, and then nodded contentedly. He guided these vast amounts of fire-based energy through the Burned Technique, gradually transforming them into strong, refined ki, which then flowed into and merged with the body vessel—expanded somewhat from the previous day. The richness of the fire energy in the molten world had greatly surprised Xiao Yan, and now, with the turbulent energy tempered and stabilized by his cold liquid, absorption became effortless. At this pace, he was confident of reaching the six-star Emperor level within three months. Xiao Yan's first training session in the molten world lasted only about an hour, after which his tightly closed eyes slowly opened. Fire glimmers danced across his dark pupils, and a warm breath escaped through his throat, gradually dissipating. Gently clenched his fists, feeling the fullness within his body, Xiao Yan couldn't help but smile faintly. Indeed, this place was exceptionally suited for him. Having only practiced for under an hour, he could already sense a subtle refinement in his ki. The progress would undoubtedly be remarkable if he continued like this. The only drawback, however, was the overwhelmingly still and oppressive atmosphere—long-term cultivation would require a great deal of patience and resilience against Duolu's quietness. Training itself was inherently monotonous; to achieve strength beyond ordinary reach, one had to exert efforts far beyond the ordinary. No strength ever came effortlessly—this truth, which Xiao Yan had learned through countless experiences, had long since become second nature. Even knowing that training here would be particularly taxing, he had still chosen it without hesitation. After becoming familiar with the molten world for nearly a full day, Xiao Yan finally began practicing the "Six-Heaven Flowing Body Technique." The environment here was simply perfect for cultivation. The initial cultivation journey naturally proved the most arduous. The Liu He You Shen Chi technique was already quite advanced, and its cultivation demanded significant effort. Fortunately, Xiao Yan possessed a strong innate talent for cultivation, and with the soul imprint guidance from the scroll, he had navigated several detours. After enduring several days of grueling practice within the molten rock, and surviving numerous critical encounters as the molten rock surrounded him, he gradually began to grasp the essentials and could now perform the technique with a semblance of form. Though this still fell short of full mastery, achieving such progress within just a few days was already an exceptional accomplishment. With sufficient time, it was certainly feasible for Xiao Yan to fully master the "Liu He You Shen Chi" technique.
