When Xiao Yan rushed to Xiao Yi Xian's residence, he found that the entire area had already been sealed off from top to bottom by a layer of energy light curtain. Outside the curtain, several senior deans of the inner halls stood solemnly, gently pushing away the curious students who had gathered. A dark figure approached steadily, and in the next instant, appeared directly outside the curtain. As the senior deans prepared to intercept, they saw the visitor's face and immediately relaxed, bowing slightly to Xiao Yan and stepping aside. "The Grand Senior Dean is inside. Go in quickly—be careful of the toxic gas," one of the deans said promptly upon seeing Xiao Yan. Hearing this, Xiao Yan's anxiety deepened. He nodded, and a vibrant green flame surged from within him, then charged straight through the light curtain. As he entered, a slightly tangy gray mist rushed toward him, but upon contact with the green flame, it hissed and was instantly vaporized by the intense heat. Ignoring the swirling gray mist around him, Xiao Yan hurried through the courtyard, then paused, gazing at Su Qian, the Senior Elder, who was pacing back and forth at the entrance. He quickly spoke, "Senior Elder, what's happened?" Upon hearing Xiao Yan's voice, Su Qian turned around promptly, exhaled in relief, and gestured toward the house with a weary smile, "I have no idea what's going on. Today, a senior elder came to report that this area has been continuously emitting a toxic vapor—several students have already fallen ill and fainted. I had to seal off the area. I originally intended to enter and investigate, but the air inside is so thick with poison, with an extremely strong corrosive effect. If I force my way in, I fear..." Xiao Yan's heart suddenly tightened, a sense of unease rising within him. He took a deep breath and stepped forward, ready to push open the door. Just as he moved, Su Qian, observing his action, hesitated slightly, then also stopped his hand, which had been raised to block him, and sighed, "Be careful." Xiao Yan nodded, pushed open the door with his hand, and then a steady emerald flame rose gently, enveloping his body tightly. He then stepped slowly into the room, now shrouded in a haze of gray-purple toxic mist. As the door opened, a strand of the mist drifted out. Su Qian immediately activated his qi to enclose it, carefully refining it. With a sweep of his sleeve, the door closed once more. He shouted loudly, "Xiao Yan, if there's any issue, let me know!" "The Senior Elder need not worry. Just seal this area off and ensure no one else enters." A serious voice came from within the room. Su Qian nodded, then stepped back, gazing at the room with slight hesitation. Suddenly, his hand seal shifted, and a surge of qi erupted like a flowing ribbon, cascading down from the sky and fully enclosing the room. Still feeling uneasy, he then summoned spatial power, adding a second layer of defense beyond the qi shield. It's no surprise that Su Qian has been so cautious—regarding the toxic energy within Xiao Yixian's body, even he feels particularly wary. Should this toxic energy spread unchecked, the entire inner academy might fall victim to it, with little left but scattered bones and ashes. "Ah, I hope Xiao Yan can resolve this matter," Su Qian sighed, finally exhaling a deep breath as he gazed at the closed room, a faint smile of weariness playing on his lips. After walking approximately fifteen steps, a soft pink bed appeared clearly in Xiao Yan's line of sight. On the bed, a slender figure was gently curled within the thin blanket, the delicate contours of her form subtly outlined by the folds of the fabric. The thick toxic mist that had been filling the room continued to seep out steadily from within her body. Noticing the approaching footsteps, the figure in the blanket trembled slightly, then her eyes—gray and purple, filled with pain—glimmed out, fixed on the black-robed young man approaching the bed. With a soft voice laced with an unmistakable bitterness, she murmured, "It seems the厄难toxic constitution is about to erupt prematurely..." Though Xiao Yan had anticipated this, he could not help but visibly pale upon hearing it. Gazing at the pain and paleness on her face, he quickly sat down beside the bed, offering a gentle reassurance, "Don't worry, I'm here with you." Xiao Yan knew well that, with Xiao Yi's current abilities, she could at least contain the厄难toxic constitution for another year. However, each time she had recently unsealed the constitution's defenses, the timing of its eruption had been significantly advanced Hearing this, Xiao Yixian hesitated slightly, and her long, slender arms extended from her back. At this moment, an eerie purple glow subtly emanated from her arms, deepening the seriousness in Xiao Yan's eyes. With his fingers resting on Xiao Yixian's wrist, a delicate flame seeped into the contact point and swiftly surged into her body. As the flame penetrated deeper, Xiao Yan's own expression grew increasingly grave. Almost the entire interior of Xiao Yixian's body was now filled with toxic vapors, and these toxins were steadily rising, heading toward her brain. Xiao Yan knew that if the toxins reached her brain, Xiao Yixian's consciousness would gradually fade, and eventually, she would reach the most tragic of all endings—dying as she had been born: born in adversity, dying in adversity! Watching Xiao Yan's gradually worsening expression, the lively gleam in Xiao Yisheng's eyes slowly dimmed. She gently bit her lower lip, speaking softly, "Xiao Yan, these days having followed you, I've been very happy. You're my first friend—perhaps even my last. If I truly reach that point, please don't hold back. I really love this academy. I don't want to lose my mind in the process..." "Shut up! What are you babbling about?" Hearing Xiao Yisheng's words, which sounded like a final testament, Xiao Yan's brows furrowed and he sharply exclaimed. After a sharp reprimand from Xiao Yan, the young physician remained unfazed, instead offering a gentle, charming smile. She slightly tilted her head, leaning against the pillow, her pair of luminous, ethereal gray-purple eyes softly fixed upon Xiao Yan as his complexion shifted. This feeling of being cared for and concerned—she hadn't experienced it much before—and now, it seemed, it was truly delightful. As for the young physician's gaze, Xiao Yan was currently too absorbed to pay attention. His brows were tightly furrowed, deep in contemplation. The method for fully controlling the厄难toxic body—the so-called toxic pill technique—still lacked the magical core of the day-toxic scorpion dragon beast, which was one of its essential components. Without it, the technique would fall short; attempting to implement it forcefully would only result in squandering the painstakingly obtained Bodhi transformation saliva. Xiao Yan desperately stirred in his mind, searching through the prescriptions left by the medicine elder for a temporary method to suppress the Hard-Adversity Poisonous Body. Yet the outcome was deeply disheartening—since the Hard-Adversity Poisonous Body was already extremely rare, and the medicine elder could hardly have devised a special technique tailored specifically for it. Thus, Xiao Yan’s search yielded no results at all. "Hehe, the厄难毒体—such a renowned name, everyone from the elder generations surely knows about it," said Tian Huo Master with a gentle smile. "But it seems your friend is now at the final stage of the厄难毒体's eruption. If left unsealed, once the toxic vapor reaches the brain, the consequences would be… severe." "Sealing?" At this, Xiao Yan was momentarily startled, then took a deep breath and asked, "Master Yao, do you know the method of sealing the厄难毒体?" "It's fortunate that you've encountered me at this time. This sealing technique is now quite rare across the continent—indeed, few even know of it. Back then, I had a friend who suffered from the厄难毒体, and it was I who devised this sealing method for him. Unfortunately, however, this sealing can only be performed once, and even then, it lasts at most three years. After three years, I still haven't found a way to fully resolve the厄难毒体. Thus…" Tian Huo Master sighed softly. Hearing this, Xiao Yan was also momentarily stunned. Indeed, it seemed that no matter how unlikely, fate always found a way—after a brief moment of admiration, he exhaled in relief. Three years of sealing had been ample enough. He simply wouldn’t believe that he couldn’t obtain the mythical poison scorpion dragon’s essence within that span! Seeing this, Xiao Yan also smiled, then as if remembering something, cleared his throat and stammered, "Um... to perform this seal, I'll need to remove all my clothes..." As soon as Xiao Yan finished speaking, the young physician's cheeks instantly turned bright red.
