Within the stone tower, Xiao Yan gazed at the elderly figure with closed eyes, enveloped in flames, and though he had not sensed any immediate change, a subtle sense of relief settled in his heart. Now that the body had been successfully forged, the subsequent steps no longer depended on him—provided the old doctor could seamlessly integrate with this body, Xiao Yan would truly be reborn. Wiping the cold sweat from his forehead, the continuous process of body refinement over these days had placed a significant strain on him. Fortunately, his storage seal contained ample medicinal pills, offering strong endurance, which allowed him to persevere. "Master, now it truly rests with you..." Xiao Yan murmured softly, then settled onto the stone platform beside him, closing his eyes gently and entering a meditative state, beginning to recover from the extensive depletion accumulated during this period. As Xiao Yan entered his state of cultivation, the stone tower once again fell into quiet, save for the steady, rhythmic sound of flames burning. With his eyes closed, Xiao Yan's half-day of meditation passed swiftly. Only when his body's qi had been fully restored did he slowly open his eyes, a subtle gleam passing through his dark gaze before settling into stillness. After restoring his state, Xiao Yan first turned his gaze to the pedestal, where the elderly physician remained motionless, eyes closed, showing no signs of movement. Seeing this, Xiao Yan furrowed his brows slightly, yet remained calm—this was entirely normal. The various components used by this body were no ordinary things, and complete integration with the physician would not be as straightforward as one might imagine. "My current strength still hovers around the peak of a One-Star Domain Sovereign, though these recent battles have been highly beneficial. If I calculate carefully, I'd say I've now reached the pinnacle of a One-Star Domain Sovereign." Gathering his thoughts, Xiao Yan found himself pondering. After consuming the three thousand Fiery Flames, although his strength had surged significantly, his recovery speed had returned to normal. With this steady, consistent cultivation, Xiao Yan believed it would take at least another half year to reach the level of a Two-Star Domain Sovereign. Yet, as his relations with the Spirit Palace grew increasingly strained, and they had clashed on multiple occasions, though he had remained unharmed thus far, he knew that the true powerhouses of the Spirit Palace had not yet appeared. When those formidable warriors finally stepped onto the stage, it might just be his turn to face adversity. Under the growing pressure of the Spirit Palace's might, he had to accelerate his own development. For Xiao Yan, the fastest way to enhance his strength was undoubtedly to absorb the hetero-flames. However, now that he had secured the Three Thousand Yan Flames, he had no news at all about the others. The Hainxin Flame, which the elderly Mu Gu elder had long coveted, remained elusive—since Xiao Yan had ascended to the level of Battle Sovereign, the elder had vanished without a trace, no longer appearing before him. As a result, Xiao Yan had abandoned any ambition to forcibly seize the Hainxin Flame. "Hetero-flames..." Xiao Yan gently stroked his fingers, then suddenly paused. With a flick of his finger, he summoned his storage ring, and several ancient scrolls materialized in his hands. These three ancient, fragmented maps were the mysterious charts he had obtained over the past several years, detailing the information about the third-ranked hetero-flame on the Hetero-Flame Ranking—the Jinglian Spirit Flame. With his growing strength, Xiao Yan now fully understands the exceptional nature and rarity of the top-ranked hetero-flames on the Hetero-Flame Ranking List. The Jinglian Spirit Flame, in particular, is renowned for its mystery—even the Ye Lao has never witnessed it. Over the years, Xiao Yan has studied numerous records, yet has found no trace of information concerning the Jinglian Spirit Flame. Without the ancient maps in his hands, he might even doubt whether such a flame truly exists in the world at all. "Three ancient maps... still no clear reason emerges." Xiao Yan carefully arranged the three fragmented maps before him and studied them thoroughly, yet remained helpless, shaking his head in frustration. The vast continent of the Battle Spirit Realm presented such a broad terrain that the geographical features depicted on the maps were entirely indistinct. The winding, tangled routes left Xiao Yan deeply puzzled. "Oh well, it seems we'll have to find that last ancient map. Otherwise, no one will ever know where the Pure Lotus Demon Fire is located." After struggling fruitlessly, Xiao Yan couldn't help but give up, looking deeply discouraged. He had already been blessed with these three ancient maps—receiving them was a stroke of luck. As for the final one, however, he had absolutely no clue. Despite years of searching, he had gathered not a single piece of information related to it, and even doubted whether that final map still existed at all. "All we can do now is hope for continued good fortune," Xiao Yan sighed softly, carefully placing the three maps aside. No matter how slim the chances of obtaining them, as long as they were tied to the Pure Lotus Demon Fire, he would never let them go. Preserved the ancient diagrams, Xiao Yan hesitated slightly, then clenched his hands, and several fragments of pale jade-like bones appeared in his grasp. These bones, naturally, were fragments of the remains of a Dao Saint from an ancient sanctuary. What truly stirred Xiao Yan's interest, however, was not the bones themselves, but the traces of Dao Saint marrow hidden within them. Xiao Yan gently rubbed his palm against several fragments of pale white bone, and after a moment, opened his mouth to release a surge of purple-brown flame that instantly enveloped the bone fragments. The intense heat quickly spread throughout the area. These bone fragments were exceptionally hard to break; without the powerful hetero-flame of the Three-Thousand-Lotus-Heart Fire, which Xiao Yan possessed, even if he knew that the bone fragments contained the marrow of a Battle Saint, he would have had to watch helplessly. Of course, even with the aid of the Heterogeneous Fire, extracting the Dou Sheng marrow from within the bones proved no easy task. Fortunately, Xiao Yan had anticipated such challenges, so when he saw the bones burning fiercely yet remaining as solid as a rock, unmoving in the slightest, he remained calm and composed. He steadily increased the temperature, slowly and patiently refining the bones through calcination. The tip of his finger pressed against the gray skeletal remains, and with a soft *p* sound, the bones softened and settled, dissolving into a gentle stream of gray ash that drifted down. As the ash fully settled, three translucent, jelly-like substances—each about the size of a thumb—appeared before Xiao Yan's gaze. These small gel-like formations had a thin, gelatinous layer on their surface; through this layer, the liquid within seemed to flow subtly, releasing a remarkable and unusual energy that gradually warmed Xiao Yan's eyes. From his storage amulet, he carefully extracted a jade vial, placing two of the Saint-Level bone marrow gel particles into it. Then, holding the last one with his fingers, he hesitated before gently pressing it into his mouth. The gelatinous droplets dissolved almost instantly upon reaching his mouth, and before Xuanyin could even recover, a vast, pure surge of energy poured in like a flood, rushing down his throat and then surging forth with a roaring force, sweeping through his entire body. Suddenly overwhelmed by such an intense influx, Xuanyin's body temperature rapidly rose, and wisps of white vapor even began to rise from his head. Sensing these internal transformations, Xuanyin promptly settled into a meditative posture, quickly entering his cultivation state to refine and integrate this sudden, overwhelming power. This refinement process lasted for three full days, and only then did Xuanyin's closed eyes slowly open. Feeling the unprecedented abundance within him, he involuntarily took a deep, refreshing breath. According to his own sense, he had now not only surpassed the one-star level but had truly reached the two-star stage! A single marrow globule, its efficacy surpasses even ordinary seventh- or eighth-rank elixirs—elixirs capable of elevating a Duke-tier powerhouse by one rank are rare indeed. A resounding roar echoed, and Xiao Yan's face instantly paled. His body shot upright, his gaze sternly directed toward beyond the stone platform. "The Spirit Palace... has finally arrived!"
