Not only Han Li, but the other cultivators were also astonished. However, the increase in spiritual power among those at the Consolidated Stage and above was barely noticeable—equivalent to mere months of rigorous meditation and practice. In contrast, the gains for the Transcendent Stage cultivators were significantly more substantial; after a single gong strike, they seemed to have gained the equivalent of over a decade of dedicated cultivation. This brought great joy to the Transcendent Stage cultivators. Meanwhile, the Consolidated Stage elders expressed some surprise and doubt. Yet regardless of who it was, every single person’s gaze instantly fixed itself on the massive black gong, glowing with intense hunger, excitement, and fervor—so eager to seize it that they seemed ready to snatch it right off the ground. Simply hearing the sound of this object could instantly enhance one’s cultivation level—what a marvel! Although the gong appeared to carry a considerable counter-effect, causing the person who struck it to lose both vital essence and life force, it was still undoubtedly a heavenly-level treasure. Could this indeed be the legendary Xuan Tian treasure? Some of the more established figures from both clans began to quietly murmur in contemplation. Han Li gazed at the black drum with equal astonishment and growing doubt. Unfortunately, his divine awareness was severely limited within the Black Domain, preventing him from scanning the distant black drum. Otherwise, as one already possessing the Xuan Tian Fruit, he would have been better able to verify whether this treasure truly belonged to the Xuan Tian lineage than anyone else. At that moment, the strongman who had transformed into a white-haired elder on the raised platform suddenly placed his purple bronze hammer with respectful dignity upon the black stone table before him. With a flash of spiritual light from his feet, he instantly vanished from his spot. Yet, in the next instant, a new figure appeared beside the massive drum. This figure wore a silver brocade robe and bore a golden dragon-headed mask on his face, with unusually emerald-green eyes—clearly not of ordinary human origin. As soon as this figure appeared, the attention of the guests on the flying pavilion immediately turned toward him. After a brief sweep of his emerald-green gaze across the surroundings, the golden-faced figure lightly cleared his throat and spoke: "Ah, I'm sure you've all personally experienced the marvel of this 'Qitian Drum' just now." And this very gong we just struck is a small gift that Black Domain has prepared for each of you. At the same time, this 'Heavenly Unity Gong' is one of our flagship treasures presented for exchange—indeed, it is the very first treasure brought forth in this exchange assembly. We are confident that, given its value, it will surely meet and exceed your expectations! "Wait—this is actually being offered for exchange?" Though most had already suspected as much, upon hearing Jinmian's words, several people immediately exclaimed in surprise. "As long as we can present a treasure that satisfies me, what could be more difficult than exchanging this Heavenly Unity Gong?" Jinmian chuckled, his tone remarkably confident. "This does seem rather unusual. I've attended your Black Domain's assembly events countless times. While I can't say your domain has always offered ordinary treasures, such extraordinary, transcendent-tier items have been rare—especially after so many exchanges. And now, this is the very first such treasure to be presented for exchange!" Could it be that, in light of the great calamity impending, your realm is also taking proactive measures? A remarkably elderly voice suddenly resonated throughout the void, its origin indistinct—seeming to emanate from one of the stone pavilions. Han Li felt a sudden sense of alertness upon hearing this, naturally recognizing the calamity the speaker referred to as the magical disaster expected to unfold over the next thousand years. Clearly, however, the two clans attending the Black Realm's exchange gathering were already familiar with the details of this magical disaster. No one was surprised by the elderly voice's remarks at first; instead, all eyes turned to the golden-faced figure, watching closely as he responded to the question. But there is one matter that the previous guest got wrong—the Qitian锣, though remarkable, does not quite reach the level imagined by the other guests, and it also has certain inherent flaws. Thus, compared to the treasures previously presented by the Black Domain, several of them actually fall short. "Flaws!" exclaimed the guest, sounding somewhat impatient. "Can you be more specific? Is this not a treasure of the Xiantian realm?" A notably cold voice emerged from a stone pavilion, clearly tinged with disappointment. "A treasure of the Xiantian realm! Heh—hely, even though our Black Domain possesses some capabilities, how could we possibly have such a treasure? Not only us, but even the Three Emperors and Seven Kings, and even among our two clans, the two great multiphase beings—none of them could claim to hold a Xiantian treasure. Such a Xiantian treasure, if it were to fall into our hands by mere chance, would only bring about the ruin of our entire clans. Otherwise, how could the siege of Tianyuan City centuries ago have unfolded, when the foreign forces launched their assault? "The Golden-Faced Elder spoke with evident intention, though his words were somewhat vague. Many of the fully evolved elders who were well-versed in the details immediately frowned. Pausing momentarily and altering his tone, he continued: "However, since our domain has brought forth the Qitian Bell as a trade offering, we will certainly explain its origin in full. Indeed, from certain aspects, this treasure embodies a subtle celestial law, possessing some extraordinary capabilities that only true heavenly treasures can possess. Its true origin, however, traces back to a long-extinct ethnic civilization deep in the wilderness—our domain's people discovered it within a forgotten sacred sanctuary there. At the time, the bell was already fragmented and its power significantly diminished. According to the ancient script of that vanished people, the bell was part of a pair—its counterpart being the Zhen Tian Mallet—both together forming the complete essence of this divine treasure. Unfortunately, despite thoroughly searching that sanctuary, we have been unable to locate the Zhen Tian Mallet." It would have to wait until after returning to seek out a master of artifact crafting, and after expending great effort—drawing upon deep-sea purple gold copper mother and other rare materials—only a replica of the Thunder Hammer could finally be forged. Yet this replica was far from successful, managing only about one-tenth of the original's effectiveness. As for the repair of the Sky-Heaven Bell, due to the unique materials used, there were no sources within this realm capable of sourcing them, so it remained unchanged. Otherwise, if the complete Sky-Heaven Bell were paired with the genuine Thunder Hammer, even if it fell short of the rank of Heavenly Treasures, its wonders would surely be quite comparable. Indeed, this is a great regret! Naturally, if that were not the case, this treasure could not have been presented as the premier piece of the domain, to be exchanged with the esteemed friends gathered here. "I am not particularly concerned whether this treasure is of Heavenly Treasure rank; what I truly wish to know is its specific powers and any shortcomings." A gentle female voice echoed in the void. "Of course, I shall explain in detail. Just now, the beneficial effects of this drum's enhancement have been made clear to all of you. However, this divine ability is only effective upon beings at the Huashen stage or above. A Huashen-stage cultivator who hears it once gains the equivalent of thirty years of rigorous cultivation; a Lianxi-stage being gains ten years of saved cultivation effort; while a Heting-stage cultivator experiences only a negligible effect—merely avoiding several months of seated meditation. Nevertheless, for any individual, the drum's efficacy is limited to the first three hearings; beyond that, no matter how many times the drum sounds, it yields no further benefit. Moreover, when the drum is struck, if the number of listeners exceeds a certain threshold, the amplification of spiritual power significantly diminishes. "The Golden-Faced Man explained one by one. Upon hearing the limitation of repetitions, the fervor in the eyes of the audience at the stone pavilion faded considerably. Most of them shook their heads, their thoughts now subtly altered. "Not only that, but ordinary cultivators are generally unable to accomplish the act of striking this drum." A body-builder must be selected, specifically trained in a foreign cultivation technique obtained from the same secret location, and advanced to a certain level before the bell can be struck. However, since the Qitian Bell itself is fragmented and incomplete, the person who strikes it will not only enhance others' spiritual power but also suffer from the counteracting force of the bell's inherent laws—losing both vital essence and life force, eventually succumbing to death. Therefore, using this bell requires considerable effort to cultivate a dedicated team of body-builders, making the process quite cumbersome. Nevertheless, once properly utilized, the Qitian Bell proves quite valuable—especially for those with numerous disciples. "The golden-faced man finished his explanation with a flicker of his gaze. Nevertheless, even after hearing the Golden-faced Daoist's explanation, it was clearly evident that many people on the platform remained deeply interested in this treasure. After a moment of silence throughout the hall, someone spoke up: "Could you tell us what exactly this treasure will be exchanged for? I assume ordinary items would be of little value in your realm." "Ah, that's not certain at all," the Golden-faced Daoist replied, surprising many. "I'll first list several items. If any of you can present one of them, you may directly take this treasure. Should none of you be able to, then the treasure may be exchanged for the finest spiritual stones or a large quantity of spiritual herbs aged for over a thousand years. Of course, the amount required will surely be an unimaginable sum." "Indeed?" The unknown female cultivator, clearly genuinely enthusiastic about the Celestial Drum, perked up and asked with renewed energy. "As I stand here, I have no intention of being anything but truthful." These are the items this domain wishes to exchange for—of course, not merely the Qitian Bell mentioned here. The other precious treasures displayed below may also be exchanged for these. As the Golden-Faced Man spoke, he flipped his hand, and a white jade scroll materialized. A flash of luminous energy then caused a milky-white light column to surge forth from the scroll, spreading out into the air above the stone platform, where dense rows of silver-inked ancient characters materialized instantly. Hundreds of different items appeared! "Three kilograms or more of Earth-Yin Crystal, three zhang in length of Snow-Spirit Wood, Bai-Xue Guo with medicinal properties exceeding ten thousand years..." Han Li silently recited the names appearing on the light display, his mind growing increasingly astonished.
