By now, things were no longer like they were at the beginning of the Eternal Continent, when the myriad realms first fused. Back then, many people didn't even understand the value of exotic treasures. But today, anyone with even a bit of insight knew well how precious they were. To a certain extent, they represented foundation—the best items to be refined into lifebound treasures. Not only did they offer greater growth potential, but many also contained innate prohibitions bestowed by the heavens.
Among items of the same grade, the value of exotic treasures was the highest—often transcending their grade classification, to the point that they couldn't even be properly priced.
These treasures had long been scattered across the world. Yi Tianxing was certain: with the power of the General's Valley, it was impossible that they didn't possess any exotic treasures. In fact, leveraging their influence, they likely held no small collection of them.
Barter trade—exchanging treasures that held little personal value for others more suitable—was a common and wise strategy.
"If it's a barter trade, then see if this exotic treasure suits your needs,"said Hua Mulan after a brief moment of thought, pulling out a strange object from her storage pouch.
It was a peculiar building—a great hall of ancient design, whose internal towers and layout differed from any typical architecture. It seemed to have been constructed in accordance with the Fuxi Bagua, incorporating the Four Symbols and Five Elements.
At a glance, one could sense the profound heavenly truths and Daoist charm contained within it. It was clearly a naturally extraordinary treasure.
"What is this exotic treasure building?"Yi Tianxing asked, immediately intrigued.
No exotic treasure building was ever useless—each carried inconceivable powers. For Xuanhuang City, more exotic buildings meant more foundation. A properly integrated structure could enhance the entire city's strength by severalfold or even dozens of times.
"This is called the Celestial Observatory (钦天监).From what I know, it's used to monitor celestial phenomena and predict major shifts in the world,"said Hua Mulan.
She didn't fully understand its use—she'd only heard of the name "Celestial Observatory" before. In her mind, it was simply a title, and this was just a building that bore it.
But when Yi Tianxing heard the name, a tremor ran through his heart.
In every dynasty of ancient China, the Celestial Observatory was an essential institution.
In Chinese history, it held a mysterious and critical role, responsible for observing celestial signs, calculating solar terms, and formulating the calendar.
From the Qin and Han to the Southern Dynasties, positions like the Grand Historian oversaw astronomy. Later, under the Sui dynasty, it evolved, eventually becoming the Bureau of Astronomy under Tang, changing names repeatedly—Secretariat Pavilion, Armillary Sphere Supervision, etc.
But in essence, it was a department responsible for:
Celestial observation
Calendar formulation
Disaster surveillance
Guiding sacrificial rituals
In many cases, state rituals and offerings were planned under its jurisdiction. Empires would gather talented mystics and scholars under its banner. They held considerable sway over imperial decisions and public sentiment.
And now, such a legendary building had appeared as an exotic treasure.
Yi Tianxing had every reason to believe that this structure had been birthed by the concept of the Celestial Observatory itself—closely linked to its historical counterpart. Even if not, it was a treasure he could never let go.
Every exotic treasure building was a priceless artifact, its value endlessly deep and always worth exploring.
"Very well. If you're trading the Celestial Observatory, I have no objections.But since it's an exotic building, its value far exceeds ordinary treasures of the same grade.I'll add 500,000 Eternal Coins as compensation."
"Agreed. It's of no use to me. Trading it for something more practical is what I need now,"Hua Mulan responded without hesitation.
Rather than hold onto something useless, it was better to trade for something that could help defeat the Flower King. Although space-type treasures were usually one-time-use, if they could slay the Flower King, it was all worth it.
The deal went smoothly.
Yi Tianxing handed over the coins not in a storage pouch, but had them piled directly onto the ground, forming a golden mountain of shining Eternal Coins.
It was an awe-inspiring sight—even Feng Xianlin and Xue Kunlun were momentarily stunned.
Once Hua Mulan swiftly collected the coins, they snapped out of their daze.
Celestial Observatory(Exotic Treasure Building)
Function:
Reveals changes in heavenly qi, celestial bodies, and natural phenomena
Can perceive and monitor weather patterns, storms, thunder, snow, heat waves, etc.
At its peak, it can peer into the heavenly secrets, observe the river of fate
Inside this structure:
Astrologers gain a threefold boost to astrology abilities
Seers (Heavenly Secret Masters) experience a tripling in their ability to foresee weather events, floods, and droughts
Yi Tianxing received this knowledge from the Wordless Heavenly Tome, which revealed part of the treasure's nature.
Although only a Yellow-Grade exotic building, its powers were miraculous and profound. Once word got out, countless astrologers and seers would flock to it, eager to train. The ability to see heavenly mechanics and observe the shifting stars was invaluable.
"A real treasure.Even if I can't use it now, it will be vital in the future.I've made a huge profit with this trade,"Yi Tianxing thought in joy.
The gains from this celestial journey were far greater than his first trip, and their impact on Xuanhuang City's strength was immense.
However, the Celestial Observatory cannot be upgraded by ordinary means. To advance in grade, it must fuse with compatible treasures.
Yi Tianxing had already thought of two suitable artifacts:
To upgrade from Yellow to Profound Grade, insert 1 rare treasure.
To advance to Earth Grade, 2 compatible rare treasures are needed.
For Heaven Grade, it requires 4—all new and compatible with the Celestial Observatory.
Such items were exceedingly rare, far beyond the reach of ordinary cultivators.
"Also, I want a batch of military supplies.The High Priest may be terrifying, but I, Hua Mulan, do not fear him."
She sat down with a smile, fully aware of the undead army's imminent assault. As one of the Four Generals, she wouldn't miss this chance to upgrade her army.
"Alright. I'll purchase the Desert Storm Armor and Blood Crystals of the War Fiends from General's Valley.Payment will be in Eternal Coins.All other military transactions will also be done in Eternal Coins—this is Lord Yi Tianxing's rule,"Yi Tianxing said with a smile.
There was big profit to be made here. Naturally, he wouldn't refuse.
Feng Xianlin and the other generals began issuing orders. Supplies started moving.
Transaction Results:
Desert Storm Armor:
1,000,000 sets total
600 Eternal Coins per set
Total: 600 million Eternal Coins
Blood Crystals of the War Fiends:
100,000 pieces from each general = 400,000 total
1,500 Eternal Coins per piece
Total: 600 million Eternal Coins
Grand Total: 1.2 Billion Eternal Coins
This astronomical sum was staggering. Even Yi Tianxing himself carried only slightly more.
Feng Xianlin and the others were visibly shaken. A fortune of this magnitude could make someone instantly wealthy—a true test of one's willpower.
But they remained firm. Once the Eternal Coins were in their hands, they immediately began purchasing military supplies.
Among them were:
Bone Battle Bows
Bone Blades
Bone Spears
Talisman Bombs
Rune Arrows
Bone Shields
All of them came from the Tower of the Primal Emperor and were distributed by the thousands.
