Chapter 825

Cai Lin's slender willow waist, easily clasped in one hand, gave way below to a wild, colorful serpent tail that swayed slightly, revealing an unmistakable allure.

Cai Lin had completed her evolution, so she could freely shift among three forms—and now she was in her original, most primitive human-head, serpent-body form.

At this moment, Xiao Yan's blood surged, his heart pounding fiercely, for Cai Lin was born with a seductive charm that, for men, was the most potent elixir; with her current strength, this charm had reached a state of perfect control, usually hidden—but now, for some reason, it had been unconsciously released.

"That stone isn't a Nine-Colored Primordial Stone, is it?" After hearing Cai Lin's words, Xiao Yan knew this wasn't the time for such thoughts—he immediately activated the Burning Scripture to suppress his inner urges and asked sharply.

Hearing Xiao Yan's voice, Cai Lin pressed her red lips tightly between her pearl-like teeth, restraining the primal impulse within her, and said: "That's not a Nine-Colored Primordial Stone. Though its appearance is similar, it's definitely not one—it's a naturally formed Primordial Stone."

The Seven-Colored Primordial Stone is a mutated, special Spirit Stone with strong ties to the Seven-Colored Devouring Sky Serpent; it only appears with slight probability at the death sites of Seven-Colored Devouring Sky Serpents, and when infused with Swallowing Heaven Snake Blood, it generates an extremely unique energy—one that serves as true nourishment for the Seven-Colored Devouring Sky Serpent.

The Nine-Colored Primordial Stone is born only when over a hundred Seven-Colored Devouring Sky Serpents perish simultaneously in one place.

"Could it be a Primordial Stone formed from the blood of the Swallowing Heaven Snake's progenitor?" Xiao Yan frowned; he naturally knew the conditions for the Nine-Colored Primordial Stone's birth, but more strangely, the Dou Qi Continent only had records of three divine beasts: the Ancestral Dragon, the Phoenix, and the Snake Mother.

These corresponded to the three great monster races: the Grand Void Dragon Clan, the Ancient Heavenly Phoenix, and the Ancient Heavenly Snake—yet despite the Tun Tian Mang Zong's strength being no weaker than the Ancient Heavenly Snake's, records concerning the Swallowing Heaven Snake were exceedingly rare.

Cai Lin shook her head slightly, her beautiful eyes filled with confusion: "I don't know either, but when I saw that Primordial Stone, my bloodline surged uncontrollably—this impulse was far more intense than when I first encountered the Nine-Colored Primordial Stone."

Monster bloodlines carry genetic memory; at the Space Pai Mai Chang, even Xiao Yan couldn't tell the Seven-Colored Primordial Stone was actually a Nine-Colored one—only Cai Lin could, because after her successful evolution, her bloodline awakened, carrying fragments of genetic memory.

Just as the Grand Void Dragon Clan's bloodline isn't the ultimate limit, the Nine-Colored Swallowing Sky Python must also have an original bloodline—but the source of this original bloodline remains a mystery to this day.

"To find out what it truly is, we'll need to test it with blood," Xiao Yan sighed helplessly, for he was broke.

Since becoming an Alchemist, he hadn't felt poverty in a long time.

Just as Cai Lin was about to speak, Xiao Yan shook his head knowingly: "That might be the only one in this world—if we don't get it now, we may never get another chance."

Though Xiao Yan had considered stealing it, this was the Shang Zhi Da Lu—even a Sky Supreme wouldn't dare cause trouble here.

Once, an Elder Giant from a supreme faction coveted a Supreme Treasure but lost the auction—then he directly attacked in the Pai Mai Chang, murdering the auction house's managers and his rivals on the spot, seizing the treasure and walking away.

The incident shook the Shang Zhi Da Lu, and in response, numerous powerful factions swiftly besieged the Elder Giant's top-tier faction; within mere days, they suffered heavy casualties, the Elder Giant himself was gravely wounded, and he was ultimately forced to return the Supreme Treasure and pay an enormous compensation to quell the outrage.

The Shang Cheng Alliance includes even the Elixir God Clan and the Ancient Myriad Grasslands—who dares steal here?

"Though I have no funds now, I can still borrow," Xiao Yan smiled, for while he had no money, he could always swindle the Furious Mountain Medicine Saint—he was a Grandmaster Alchemist with immense wealth!

A soft hum—the Flame Sealing dissolved.

"Brother Xiao Yan, are you two alright?" Seeing they were unharmed, Xun Er and Xiao Yixian finally relaxed.

Xiao Yan said: "We're fine—the plan changed. That divine stone might trigger Cai Lin's bloodline transformation, so we need to bid for it."

Without Xiao Yan explaining, everyone had already guessed most of it—Cai Lin's bloodline had surged visibly just now, a clear sign of spiritual beast bloodline awakening, meaning she'd encountered a Secret Treasure perfectly suited to her evolution.

"But you probably don't have enough funds to bid now," the Furious Mountain Medicine Saint smiled, stroking his beard as he gazed at Xiao Yan.

"Uh," Xiao Yan coughed twice, stepped up to the Furious Mountain Medicine Saint, and placed a hand on the old man's shoulder, grinning: "I don't, but you do."

"Wait, you might not have heard—the auctioneer said this item contains profound secrets; its owner is a Sky Supreme who risked his life to retrieve it from an ultimate deadly zone, and after ten years of study, still couldn't decipher it—so he put it up for auction. Its value is certainly no less than the Dimensional Embryo Companion you just bid on," the Furious Mountain Medicine Saint continued. "If it were an ordinary item, fine—but this? You'd have to bankrupt yourself to win it."

Though Xiao Yan was willing to teach Yao Chen's Pill Refining Method, and owed him a favor, he couldn't possibly ask someone to go bankrupt—the Furious Mountain Medicine Saint wasn't a true Grandmaster Alchemist; even if he had the ability, acquiring a Sky Supreme-level item would demand a colossal cost.

Xiao Yan knew this was asking too much—he smiled: "I don't want your things. I just want to borrow your 'reputation.'"

"Borrow reputation?" The Furious Mountain Medicine Saint froze—could you even borrow that?

As Xiao Yan and the Furious Mountain Medicine Saint plotted, several top-tier powerhouses stepped forward on the Auction Stage to examine the divine stone up close—and Xiao Yan sent Zhu Kun to investigate as well.

He didn't let Cai Lin verify it, fearing unnecessary trouble.

Mo He Yi stared at the gem radiating colored light, sensing its unusual nature—otherwise, the Sky Supreme wouldn't have risked his life to retrieve it from a deadly zone.

"Mo He Zhao Tian Di," Mo He Yi silently chanted, then flicked his finger, conjuring yin and yang—there was a soft pop as strands of black-and-white Spiritual Force infiltrated the gem—but upon contact, they were instantly repelled.

"Even my clan's Probe Light Divine Technique can't detect anything?" Mo He Yi was startled; though he was only a Lower Earth Supreme, less gifted than Mo He Tian, he was still the Mo He Divine Clan's Holy Son—his perception was naturally sharp, yet now he saw nothing.

"Holy Son, what mystery does this gem hold?" As Mo He Yi returned to his private booth, Mo He Ming couldn't help but ask.

"I can't be certain," Mo He Yi now looked like a normal man, his expression grave as he shook his head: "But this gem is inexplicable—it hides profound secrets, far beyond what can be understood in a moment."

Hearing this, the several powerhouses beside Mo He Yi exchanged glances—Mo He Yi was only a Lower Earth Supreme, yet he was the Mo He Divine Clan's Holy Son, and his methods were far from ordinary.

If even he couldn't determine its nature, how extraordinary must this gem be?

Other powerhouses also deployed their unique techniques—Spiritual Light Illumination flooded the gem, all methods exhausted, hoping for some reaction.

But the gem was like endless Space—sealed away; all power entering it vanished like a cow sinking into mud, silent and unresponsive.

"Stop wasting your strength—no one, not even a Sky Supreme, can penetrate something like this so easily."

"This must be a Sky Supreme-level Treasure—but if we don't know its use, it's useless."

"If they knew its use, you think the Sky Supreme would sell it?"

Instantly, the silent Pai Mai Chang erupted again—many murmured over this marvel.

Some believed it was an ultimate treasure, beyond even a Sky Supreme's comprehension; others thought an item with unknown use was just a stone—no matter how precious, still just a stone.

Soon after, Zhu Kun returned, shaking his head helplessly: "I used Void Manipulation to probe what's inside, but still couldn't discern anything."

"This Auction Item is a Registered Item," the auctioneer said after all the powerhouses had left in frustration: "Its owner doesn't want Spirit Liquid—he only accepts Exchange Offers. The seller is present—dear guests, if you have what he needs, make your offer; if it's what he wants, the gem is yours."

"I have the Kun Peng Bone of a Quasi-Superior Beast," the Northern Sky Dragon Emperor stood again, offering the same bone.

"I don't need resources from Spiritual Beasts," a voice came from the center of the Sky Tower—the tower had remained mysterious, never bidding, and now it was revealed: the seller was inside!

Hearing this, the Northern Sky Dragon Emperor sat back down, embarrassed—he'd bid twice today, both times failed. His Kun Peng Bone was priceless; ordinary feathered divine beasts would bankrupt themselves to buy it.

Subsequent bids mostly mirrored the last round—many had already offered their best treasures during the bidding for the Saint Pupil, so offerings were largely similar.

But all were rejected—clearly, the seller found them unworthy.

After the seller's words, a Alchemist seated in the general seats spoke: "My family possesses a White Jade Silver Immortal Pill, from the Elixir God Clan—would you accept it?"

"Damn! The Elixir God Clan's White Jade Silver Immortal Pill—that's their supreme elixir, a high-grade Divine Pill! Legend says it can restore a being even after Body Destruction and shattered soul—effective even for Sky Supremes!" A Alchemist, hearing the pill's name, was stunned.

The White Jade Silver Immortal Pill was renowned throughout the Great Thousand World—the highest-quality Healing Pill the Elixir God Clan sold publicly; ordinary people couldn't even obtain it. Clearly, this Alchemist's family had ties to the Elixir God Clan.

"White Jade Silver Immortal Pill," the booth occupants fell silent, then said: "Elixir God Clan pills are excellent—but this one won't do. If you have a White Jade Gold Immortal Pill, we'll trade."

Hearing this, everyone in the hall drew a sharp breath. Both were Healing Pills—but the White Jade Gold Immortal Pill was a Holy Pill, meant for Spirit-level Sky Supremes!

Hearing this, the Alchemist slumped back in defeat—he couldn't possibly have a Sky Supreme Holy Pill; even the Elixir God Clan's high-ups might not possess a pill of that caliber.

Brewing such a pill requires immense time and energy, and the failure rate is extremely high.

For a moment, several powerful figures with astonishing backgrounds named their offerings, but all were rejected by the seller.

Even someone who offered a Supreme-level Medicinal Material was turned down.

Suddenly, the entire scene fell silent, for all who could bid had already bid; those who had not bid yet but were qualified to do so were now few and far between.

Subconsciously, many people raised their heads toward the Sky, where Mo He Yi of the Mo He Clan resided in his divine pavilion. Though Mo He Yi was not Mo He Tian, he still represented the supreme authority of the Mo He Clan, and his worth was undoubtedly immense.

For a moment, everyone held their breath, all waiting for Mo He Yi to bid.

For in this auction, aside from his rivalry with Xiao Yan over the Saint Pupil, Mo He Yi had never bid before.

Amid the silence of all present, finally, a voice came from within the divine pavilion: "A Supreme's Promise."

No sooner had Mo He Yi's voice fallen than a young man's silhouette projected from countless light-years away. Though the figure was blurred and his features indistinct, one could faintly make out his handsomeness, his broad frame, and an aura of natural authority.

The projected hand swept once, and a Contract appeared. A Supreme's projection—Spiritual Energy Contract. This was the Promise Contract; if the seller accepted, the Contract would be eternally valid.

"Sssss! A Supreme's Promise!"

Upon hearing this, everyone present was shaken, for such a vow was irrevocable—it amounted to having a Supreme do one thing for you.

Imagine the potential power of a Supreme, especially a Supreme of the Mo He Clan—even destroying a lineage was possible; seizing or occupying a lineage was entirely within his capability.

And more importantly, this Promise was from Mo He Tian!
