The door swung open, and at once, a strong, soft red light surged forth, causing Xiao Yan to instinctively close his eyes. After a while, he slowly opened them again, gazing at the scene within the room, his expression growing increasingly awed. A look of astonishment flashed across Xiao Yan's eyes. He took a deep breath of the cold air, and only after a moment did he speak softly. The energy here was ten times stronger than that of the advanced training rooms on the fifth floor! Training here, he had no doubt he would truly feel that exhilarating, flying sensation. "Hmph. Otherwise, those people wouldn't be so envious of this place," said Zi Yan, proudly straightening her small chest. Xiao Yan nodded with satisfaction and stepped steadily into the room. As his figure passed through the faint crimson mist, he soon spotted a dark stone platform at the center of the training room—identical in appearance to those in other training rooms—complete with a small recess in front of it, suggesting that fire energy would still need to be drawn here as well. "This is where training takes place. Do you have your fire crystal card?" By the way, I almost forgot to mention—though this training room is better than the others, the amount of fire energy deducted is quite substantial. It seems like training here for just one day would cost the equivalent of thirty days' worth of fire energy." Zǐ Yán shook her light purple ponytail and smiled at Xiāo Yīn, showing two small tiger teeth. "Thirty days' worth of fire energy..." Such a high cost for training, even with Xiāo Yīn's current financial strength, made him feel a subtle chill at the edges of his teeth. That would mean nearly a thousand fire energy units just for a month of training here—what a burden! Honestly, if it weren't for his income from selling pills, he'd never be able to afford it. This level of fire energy consumption would even exceed what ordinary students could manage over an entire year. "Don't tell me you don't have any fire energy, or I'll have no choice but to give up." "Looking at Xiao Yan's expression, Zi Yan quickly said. She didn't understand how to generate fire energy, so she could only maintain her cultivation by drawing the monthly fire energy allocated to her from the inner academy. Although the top-ranked position granted her a considerable amount of fire energy each month, it was barely enough to sustain her cultivation here. As for contributing that fire energy to support others, she simply had no way of doing so. "No need for you to worry about that," Xiao Yan shook his head with a sigh, stepped onto the stone platform, and slowly settled into a meditative posture, then turned to Zi Yan. "I'm about to begin my cultivation now. During this period, please don't disturb me. If you need me to prepare pills, just wait by until I awaken. Absolutely don't interrupt my meditation—otherwise, you'll have to continue taking those herbs as they are." Xiao Yan's warning proved highly effective for Zi Yan, who immediately nodded so vigorously it looked as though she were tapping her head like a chicken pecking at grain—only a few steps away from making a verbal vow. Seeing Xu Yan in this state, Xiao Yan finally smiled and felt at ease. He withdrew the Fire Crystal Card from his storage ring, gently inserted it into the slot, then slowly formed healing hand seals with both hands, his eyes gradually closing... Upon seeing Xiao Yan enter his meditative state, Xu Yan pouted, gave him a sly look, and then marched out of the meditation room with a clear sense of dissatisfaction, closing the door behind her. Although the fire energy drawn from Room No. 1 was indeed exorbitant, it was no surprise that its effectiveness matched such a premium price—this was precisely what Xiao Yan thought when he first saw the dense, vibrant core of heart-fire emerging from within his body. While the heart-fire that appeared during earlier stages of cultivation had been thin and scattered, in Room No. 1, the heart-fire now formed solid, concentrated clusters, and was significantly hotter than before. Under this intense, powerful flame, the refinement of his battle energy progressed so swiftly that even Xiao Yan found himself quietly impressed. Within his body, a vast, formless flame of inner vitality rose gently and steadily near his heart, flowing through the meridians with steady, powerful qi, then being infused throughout his system. When this qi reappeared, it had transformed from thick, like the width of his thumb, into a slender, translucent strand—crystalline and clear, resembling a jade-like crystal rod. Of course, although under the intense refining power of this robust, intangible inner flame, the qi was now refined at a speed more than ten times faster, the scorching heat still caused periodic sharp pains along the meridians. Even this was thanks to the enhancement of his body’s meridians through the "Earth-Core Qi-Infusing Milk." Should this have occurred before the enhancement, with such a fierce inner flame, merely at his current level of strength, the qi would have immediately caused violent surges throughout his body, as though the internal fluids were being violently stirred and overturned. The sharp sensation, though somewhat uncomfortable for Xiao Yan, did not cause any delay at all. His mind remained focused, continuously channeling ki out from the sea urchin-type battle crystal, which now had only seven long, sharp spines. Initially possessing nine spines, the sea urchin crystal had gradually reduced to seven. After gaining familiarity with the battle spirit level over time, Xiao Yan began to grasp the underlying principles—seeming to indicate that each time his strength advanced, one of the energy spines would contract inward. Based on this observation, he speculated that once all seven remaining energy spines were fully absorbed, he would truly attain the battle king level. The unique method of assessing battle spirit strength intrigued him greatly. Compared to the vague understanding of the battle master level, this approach offered a much clearer and more precise insight into his own capabilities. Under the powerful heart-fire of the first training chamber, Xiao Yan could slightly perceive that the seventh energy spire on the sea urchin battle crystal was gradually shortening at a rather slow pace. Perhaps, when it fully retreated into the crystal, it would signify that Xiao Yan had reached the level of Three-Star Battle Spirit. Over five days, the benefits to Xiao Yan were obvious—not only had his aura grown more solid, but his internal qi had also become significantly purer. The seventh energy spike on the sea urchin crystal had shortened by nearly half, clearly demonstrating the effectiveness of his five-day cultivation. Had this been ordinary, even a full month of consistent training might not have yielded such results. On the seventh day, after finally stepping out of his cultivation state, Xiao Yan encountered Zi Yan, who had been waiting for him for half an hour. Seeing the girl's visibly unhappy expression, Xiao Yan offered a slightly embarrassed smile, quickly took over the herbs she was holding, and immediately began preparing a batch of pills for her, which helped ease her expression somewhat. After seven days of cultivation, he had surpassed nearly a month's worth of training from the past. The powerful qi surged through his body like a flood, filling every part of him with strength—this cultivation chamber truly stood far above ordinary ones. After completing the refinement of the small spheres for Zǐ Yán, Xiao Yan simply ate a light meal, stretched his limbs, and then remained inside without intending to leave. After resting for over an hour, he returned to the stone platform, once again settling into meditation under Zǐ Yán's gaze, which she regarded as that of a madman. "This madman really doesn't cultivate like this," Zǐ Yán murmured, shaking her head in resignation, and then stepped out of the chamber. … As for Xiao Yan's intention to enter the Tian Fen Qi Tower and remain in seclusion until the start of the "Strong Ranking" competition, the urgency of time naturally compelled him to remain vigilant and diligent. Should everything proceed as expected, he would be able to achieve his goal and reach the desired level by then. However, just as he had been in seclusion and practicing for nearly fifteen days, unusual occurrences began to unfold within the otherwise tranquil Tian Fen Qi Tower... Such commotion, Xiao Yan could not possibly maintain his meditation state. He abruptly opened his eyes, gazing in astonishment at the unfolding events within the training room. After a moment, his face suddenly paled, and he gasped in shock, "Why has the energy within the tower become so turbulent?" "All students within the tower must immediately evacuate the Tianfen Qi Tower!" A deep, resonant voice, elderly and commanding, suddenly echoed throughout the entire tower, lingering in every ear, fading only slowly. "Something has gone wrong within the tower..." A thought flashed swiftly through Xiao Yan's mind.
