The art of refining medicinal pills lies in perfectly blending the various healing powers of numerous herbs. This blending must be maintained at an exquisitely refined level, and precisely because of this, spiritual energy becomes the most crucial factor determining a pharmacist's ultimate achievement. This recent development has somewhat surprised Xiao Yan, as he had previously followed each step strictly according to the prescription, with no deviation at all—yet the final outcome still went awry. Clearly, something within the sequence had slipped beyond his control. Initially, Xiao Yan himself did not know which step had gone wrong. It was only when the flames surged in his eyes that he began to grasp the issue: the problem did not lie in the medicinal powders or liquids he had extracted, but rather within that single drop of greenish-red blood. This drop of vibrant, jade-red blood was extracted from the dried remains of the beast. The intense, turbulent energy it contains far exceeds the requirements for crafting the Tianhun Rongxue Dan. The powerful, wild energy within the blood alone cannot be fully harmonized merely by the combined strength of the three herbs—Dragon Blood Mushroom and Bone Spirit Fruit—meaning the blood's energy is too potent, while the herbs' energy is relatively weak. Thus, a balance between the two remains elusive. Having identified the root of the issue, Xiao Yan's furrowed brows still remained tightly clenched. Should he fail to harmonize the blood's energy, he would have to seek out another seventh-tier beast's blood. Yet, at present, aside from this jade-red blood, he had no other refined blood at hand. Therefore, he would have to settle for this one. A thought flashed through his mind, and Xiang Yan's eyes grew slightly focused. With a wave of his hand, the numerous glowing orbs suspended in the air were drawn into the medicinal cauldron. Under the sweeping surge of the emerald flames, within just a few minutes, the herbs gradually fused under Xiang Yan's precise control into a single pale blue liquid. Xiang Yan gazed at this blue liquid, subtly infused with gentle energies. With a gentle gesture of his finger, the liquid descended slowly and settled into the increasingly turbulent seething blood of a deep green and crimson hue. Upon entering the blood, the liquid—rich with the essences of numerous herbs—immediately exerted a noticeable effect. The fine, needle-like projections rapidly contracting and expanding on the blood's surface began to gently retract back into the body. Watching this scene, Xiao Yan slightly exhaled in relief—yet just as that breath escaped his throat, it suddenly froze. He clearly sensed a subtle, ever-present pressure seeping out from the drop of pale green and crimson blood, spreading gently. As soon as this pressure manifested, Xiao Yan’s internal qi momentarily stalled. Then, the previously calm green-and-crimson blood began to surge violently, as if boiling, with a powerful, turbulent force rapidly rising within it, causing the onlookers’ faces to pale. The sudden development caused everyone present to react, even Su Qian and the others, who were momentarily stunned by the pressure emanating from the blood. "What's going on?" "Something's wrong with the drop of blood Xiao Yan brought out. What kind of beast's essence is this? Even ordinary seven-tier beasts wouldn't typically emit such a strong pressure." Above, numerous elders stared in astonishment at the stone platform, whispering to one another in hushed conversation. Su Qian and Xiao Yi exchanged glances, both conveying a sense of gravity—this overwhelming pressure indicated that the lifeblood's host had undoubtedly been an exceptionally powerful being, possibly even an eighth-stage legendary beast. Where had Xiao Yan obtained such high-tier魔兽 blood? Amidst everyone's astonishment, no one noticed that Zi Yan, standing beside Xiao Yi, had a series of unusual purple glimmers flash across her gem-like eyes at the very moment the pressure manifested. Xiao Yan’s gaze was now firmly fixed upon that drop of pale green and crimson blood—indeed, the greatest issue had finally surfaced here. “As Mo Tianxing recounted on that day, this beast’s strength during its lifetime should have reached the peak of the seventh stage, or even beyond, into the eighth stage. Yet even such a powerful creature, relying solely on a single drop of essence blood, would find it difficult to project such overwhelming pressure. It seems… this beast truly possesses extraordinary origins.” A spark of brilliance flickered in Xiao Yan’s eyes. The pressure emanating from the blood continuously resisted the neutralizing effects of the various herbs, as though a subtle sense of pride still lingered within it—a pride rooted in its very bloodline. This pride refused to allow it to be transformed into a mere pill for human consumption. “Regardless of how formidable you were in life, now you are but a single drop of blood. I still don’t believe I can truly subdue you!” Stirred by the growing resistance emanating from the blood, Xiao Yan emitted a cold sigh, curled his fingers, and launched a Dragon Blood Herb into his hand. With the flames dancing upon his palm, he swiftly swallowed the herb whole, then continuously drew out various medicinal herbs from his storage ring, which he launched into the flame. The resistance of this blood far exceeded Xiao Yan's expectations, clearly indicating the immense energy it contained. Should he succeed in refining it into a Heavenly Soul-Infused Blood Pill, the resulting quality would undoubtedly reach an exceptionally high level. This Heavenly Soul-Infused Blood Pill was originally crafted by Xiao Yan for Medusa. If indeed her body harbored such a condition, it might have been intended for her son or daughter. As Xiao Yan pursued perfection in his endeavors, once he decided to refine it, he would naturally strive for the very best. With thoughts swirling within him, a droplet of blood-red liquid reappeared within the flames in his palm. "I won't believe I can't heal you!" Gazing at the deep crimson liquid, Xiao Yan gritted his teeth and with a flick of his finger, sent it swirling into the blend of green and crimson blood. The crimson liquid settled into the green-and-crimson blood, momentarily calming the latter's turbulent force. Yet soon, under the mounting pressure, it surged even stronger—seemingly intensifying each time Xiao Yan challenged it. By the time it reached its peak, the pressure radiating from the blood had grown so overwhelming that Xiao Yan's vision began to blur. In the haze, he saw a monstrous, fierce beast's head surge forth from the cauldron and crash directly into him. The phantom beast head did not appear, yet a low, dull hum escaped Xiao Yan's throat. Suddenly, he was struck with astonishment—his soul energy had noticeably weakened. Taking a deep breath, the shock in his eyes grew more intense. Amidst this shock, a quiet sense of relief stirred within him: thank goodness he hadn't rashly and indiscriminately devoured the blood. Otherwise, his body would surely have been thrown into turmoil by this very substance. At that very moment, the preparation of the pill was interrupted by the relentless pressure of the blood, which could no longer be expelled. Thus, the pill would never be successfully crafted. Gazing at the serious expression on Xiao Yan's face atop the stone platform, everyone knew that something significant had gone wrong with his current attempt at alchemy. "I have no idea where Xiao Yan brother obtained this magnificent beast's essence, yet it exudes such overwhelming pressure. As far as I know, among the powerful beast clans in the Central Region, every clan member possesses a spiritual stele inscribed with a fragment of their residual soul. As long as that soul fragment remains intact, the bloodline within their body remains unclaimed by others. This situation bears a striking resemblance to what I've just witnessed. However, this is the Black Horn Domain—how could there be beast clans here possessing such spiritual steles?" Xin Lan furrowed her brows, murmuring in quiet contemplation. Xiao Yan himself had no clue whether this troublesome beast might be a member of one of the prominent clans from the Central Region. At this moment, he was utterly overwhelmed by the sheer pressure of that single drop of jade-red blood. As Xiao Yan was experiencing a headache, Zi Yan's eyes flashed once again with a purple glow, and then she moved swiftly, darting toward the stone platform. Her slender figure seamlessly pierced through the spatial barrier and materialized on the platform. "Now, I simply don't have the time to help you prepare those pill-formations to take," Xiao Yan said, waving his hand with a sigh. "You're relying solely on medicinal herbs—this won't eliminate the pressure. That pressure originates from the bloodline. Though I'm not entirely sure which type of beast this particular creature belongs to, its lineage is undoubtedly remarkable. It might even be descended from some ancient, rare ancient beasts." Zi Yan gave Xiao Yan a withering glance, speaking with crisp clarity. Hearing this, Xiao Yan was momentarily stunned, then chuckled softly. At this point, he didn't care whether the bloodline owner was indeed an ancient beast or not—he only knew that if he didn't remove that lingering pressure within his own blood, all the rare herbs he had painstakingly gathered would be wasted. "With my blood..." Zi Yan's eyes were fixed intently on the single drop of deep green and crimson blood within the cauldron, her purple glow growing ever more intense. Before Xiang Yan could respond, she bit down on her tongue, and a drop of blood tinged slightly with purple drifted gently to land before him. With that thought flashing through his mind, Xiao Yan curled his fingers and guided the drop of blood tinged with purple to fly into the cauldron, where it settled into the drop of green-red blood. As the drop entered, the entire realm seemed to fall into an instant stillness. Then, Xiao Yan was startled to notice that the powerful pressure emanating from the green-red blood was rapidly dissipating—like snow melting into boiling water. Thanks to the soul energy permeating throughout, he could sense clearly that as the pressure faded, it carried an undercurrent of fear, as though encountering a natural enemy. Within just a few breaths, the formidable pressure that had been troubling him so greatly vanished completely. Staring in astonishment at Zi Yan, whose face beamed with pride, Xiao Yan was filled with curiosity and wonder—what exactly was her true essence?
