This was a mystery box nurtured by the Divine-Demon Treasure Tree.
In recent times, all kinds of divine and demon trees had been cultivated, each uniquely rare and precious. Among them, the Treasure Tree of Mystery Boxes stood out for the enigmatic nature of what it could produce—boxes filled with unknown possibilities. A seven-colored mystery box had a substantial chance of containing Innate-grade treasures. With good luck, one might find an Innate Spirit Treasure. With average luck, one could still obtain top-tier materials or miraculous objects of Heaven and Earth. Even with the worst luck, you would never walk away empty-handed.
It was only a question of how valuable the contents were.
Clearly, this seven-colored mystery box was no ordinary item—rare and precious. If it truly contained an Innate Spirit Treasure, it would be an incredible windfall.
Humans are drawn to gambling and mystery. Thus, mystery boxes, spiritual oysters, treasure stones, and similar games of chance were extremely popular throughout the Great Yi realm.
"This seven-colored mystery box is only for trade, not for sale," Yi Tianxing said with a faint smile."Anything of equal value will be considered."
"As it happens, I have something of interest—this seven-colored Spatial Spirit Oyster, which I retrieved from the deep sea. I'd originally planned to open it myself later, but since Fellow Daoist Yi is offering his treasure to spark exchanges, I can't be stingy. I'll trade this for your mystery box."
Pure Yang Sword Immortal chuckled as he revealed a seven-colored oyster, glowing with radiant hues. It looked palm-sized, but its interior space was anything but—mustard seed hiding Mount Sumeru.
These Spatial Spirit Oysters roamed the deep seas, appearing as unremarkable white shells. When they encountered treasure, they would swallow it and seal themselves after ten years, bathing in a quintessential glow that nourished the item inside with spatial energy.
The outer glow could block divine sense and spiritual vision—even advanced ocular techniques couldn't pierce the mystery.
Among the deep-sea clans, these oysters were highly prized for gambling. The longer they lived, the more colors their glow exhibited. A seven-colored one like this had matured for over seven thousand years, making it exceptionally valuable. If it contained anything, it would undoubtedly be a rare treasure.
In the Eternal World, popular gambling treasures included:
Mystery Boxes
Spatial Spirit Oysters
Exquisite Bones
Source Stones
There were others, but these were the most mainstream. All of them contained hidden treasures, and all were used for gambling-style exchanges.
"Of course," Yi Tianxing nodded.
While he didn't receive a guaranteed treasure, the Spatial Spirit Oyster was also an excellent gamble. He wasn't losing out.
The two swiftly completed the trade.
"Since you've already traded, why don't you open them together and see who has the better luck?"chuckled the Carefree Wanderer.
"Yes, that would be quite entertaining,"added Dao Lord Changsheng.
"Open them, open them!"chimed in Zhang Guolao and Han Zhongli, gleefully clapping their hands.
The surrounding cultivators also revealed curious expressions.
"Very well,"Yi Tianxing and Pure Yang shared a look and smiled.
"I'll go first,"said Lü Chunyang, brushing his hand across the box.
Click!
A crisp sound echoed as the mystery box opened. Radiant treasure light surged outward—Innate spiritual glow flickering inside.
When the brilliance faded, they saw a jade hairpin adorned with a blooming peony flower—flawless, delicate, and beautiful beyond words.
"A Peony Jade Hairpin—Fellow Daoist Lü, your luck is extraordinary.That is an Innate Spirit Treasure. Truly enviable,"said the Carefree Wanderer with a smile.
"Well earned, well deserved,"laughed Zhang Guolao and Han Zhongli.Clearly, for Lü Chunyang, this was a treasure worth more than any ordinary item—something he would not trade away.
"What a marvelous treasure,"Lü Chunyang said sincerely. This had solved an urgent need—he had been looking for a proper gift, and now the timing was perfect.
"Congratulations, fellow Daoist,"Yi Tianxing offered with a smile.To open an Innate Spirit Treasure from a mystery box was astoundingly rare. Out of hundreds, thousands, or even ten thousand boxes, one might not find even a single such treasure.
Even Yi Tianxing, who had opened many seven-colored mystery boxes before, had never drawn one himself.
Then, with no hesitation, he opened the Spatial Spirit Oyster.
A brilliant glow emerged, and from within… appeared a jade tome.
"Celestial Talisman Codex (通天符书)"
Ancient characters shimmered on its cover—it was an unparalleled manual, a divine scripture.
"That's a supreme heavenly book containing the arts of talismans and sigils!"
"Its grade rivals that of Innate Spirit Treasures—perhaps even greater in value.That such a thing would emerge from a Spatial Spirit Oyster…Unbelievable!"
"This luck is truly heaven-blessed!"
All the great cultivators present were utterly stunned.
This Celestial Talisman Codex was no ordinary book—it was a scripture comparable to the ancient supreme scriptures, perhaps even the legendary Heavenly Canons. For the right person, it could surpass those very texts.
It contained the entire spectrum of talismanic arts, from the most basic yellow talismans to the apex heavenly and immortal talismans. Even more importantly, it had the most comprehensive record of base sigils.
What were sigils?
They were the fundamental building blocks of all talismans—the very essence of law and order.
All talismans relied on sigils, and sigils represented the powers of Heaven and Earth.They were the embodiments of the Three Thousand Great Daos.
This codex contained the full set of all 3,000 base sigils.
From these, any talisman could be derived.
If Yi Tianxing could fully comprehend this book, his understanding of sigils and talismans would reach unimaginable heights.
Sigils were the core of universal law—mastering them was akin to mastering the fabric of reality itself.Any divine ability or technique would become far easier to comprehend and control.
With this codex, Great Yi's mastery of sigils would explode in potential, unlocking endless avenues of innovation and culture.
This tome's significance far exceeded that of any material treasure.
Even ten Innate Spirit Treasures could not equal it in worth.
To Great Yi, it was like divine rain falling from the heavens.
Once studied thoroughly, Great Yi's civilization would leap forward, surpassing imagination.Moreover, many of the talismans in this tome had never been recorded in Great Yi. Once drawn, they could drastically enhance the power of the Ten Thousand Talisman Banners, making them vastly more formidable.
Its value was beyond estimation.
In this world, the most precious thing was not magical artifacts or spiritual resources.
It was knowledge.
Knowledge birthed infinite possibilities.
"Fellow Daoist Yi, your luck surpasses mine by far.Congratulations on obtaining such a treasure,"Lü Chunyang said, genuinely impressed. He had thought himself lucky—but clearly, Yi Tianxing's fortune was even more astonishing.
Of course, he was merely envious, not jealous—this was the kind of fortune one couldn't force.
This was not only Yi Tianxing's personal fortune, but also the fortune of the entire Great Yi Dynasty—heaven-blessed and unstoppable.
"Fellow Daoist Yi, I heard you possess Reincarnation Holy Liquid.Would you be willing to trade some? I can offer a rare Heaven-and-Earth treasure in exchange,"spoke a dignified and noble woman named Yaochi—the true form of Queen Mother of the West, a being whose status rivaled that of a Sage.
"Certainly,"Yi Tianxing replied without hesitation.
He had long known her identity. The Reincarnation Holy Liquid was not difficult for him to obtain—it was only a matter of time.
Thus, exchanges continued.
People brought up what they needed—and often, their needs were quickly met.What one couldn't find elsewhere might be found easily here. These great cultivators came from all corners of the world, and their access to rare, high-grade treasures was far beyond imagination.
The exchange proceeded pleasantly and smoothly.
Before long, it was drawing to a close.
"Fellow Daoists, since you've come to Great Yi,if you are not in a hurry, I invite you to stay a while and explore.In a few days, we'll be holding our annual Immortal Delicacy Banquet—I hope you'll stay for a few cups of wine and sample the fruits of our realm.And early next year, Great Yi will hold the Heavenly Sacrifice and officially advance to a Sacred Court.If you have time, you are most welcome to attend the ceremony."
These words caused many cultivators to pause, a ripple of surprise crossing their faces.
They hadn't expected an invitation—nor had they imagined that Great Yi was already ready to become a Sacred Court.
This pace was beyond imagination.
Once successful, it would surely shake the Eternal World.
Attending such a ceremony would be a rare privilege.
"Emperor Yi's invitation is more than welcome.I've long heard of your Immortal Academy, where all schools of thought are preserved and allowed to flourish.I, a humble scholar, have long wished to travel Great Yi.Now, with this invitation, how could I refuse?"said an elderly Confucian scholar, gently stroking his whiskers, the glow of wisdom in his eyes.His very presence radiated peace and serenity.
"Indeed, such a grand event must not be missed.Of all the Fortune Dynasties in the Eternal World, Great Yi now stands at the forefront.There are few emperors who could compare to you,"Dao Lord Changsheng added with a warm smile.
