Within the Seven-Colored Warships, the blue warship was armed with a Sea God Trident. In water, it could move like a sovereign, rampaging without opposition and overwhelming all in its path.
The power of these Seven-Colored Warships was indisputable. They could soar through the skies and dive into the earth, and each possessed formidable combat strength. The only obstacle lay in the material required for their forging: Essence of Clouds. This essence contained spiritual properties and could not be condensed through ordinary means. That single requirement plunged the crafting of these warships into a deadlock, forcing a shift toward producing Giant Whale Warships instead.
It was a reluctant compromise.
However, that bottleneck was completely resolved upon acquiring the Cloudswallow Beast.
The Cloudswallow Beast (Tun Yun Beast) was a unique creature of heaven and earth, nesting in clouds and feeding on them. It could exhale mist and cloud, naturally condensing cloud qi. Wherever it resided, layers of clouds would gather, creating illusions within the cloud realm. Within a sea of clouds, the Cloudswallow Beast was a dominant force, capable of generating Cloud Essence.
This ability—to produce Cloud Essence—was what Yi Tianxing valued most.
Over the years, the Cloudswallow Beast had been placed inside the Heavenly Emperor Tower of Primal Chaos, specifically in the level where the Time Stopwatch resided. There, it rapidly grew and condensed Cloud Essence at an accelerated rate.
Cloud Essence, in truth, was the refined product formed inside the beast after it devoured cloud qi. While this essence was useless to the beast—making it feel uncomfortable—it would be expelled as waste. Visually, it resembled crystal gemstones. However, they were not easily produced; the Cloudswallow Beast could only condense one such gem every ten days.
But each piece was sizable—about as large as a human head—and imbued with spiritual properties. It was the ideal material for refining Seven-Colored Warships.
Thanks to the Cloudswallow Beast, Yi Tianxing had accumulated a significant stockpile of Cloud Essence over time. The previously abandoned warship forging project could now resume.
The ship before him had been forged using Cloud Essence as the main material.
In truth, Seven-Colored Warships did not require massive amounts of Cloud Essence. As the vessels could change size at will, just a few head-sized pieces of Cloud Essence were sufficient to forge one. Due to the unique nature of Cloud Essence, the ships could absorb surrounding cloud qi or even rare materials to rapidly grow.
They could shrink down to palm size or expand into colossal vessels capable of carrying over ten thousand soldiers. With further upgrades, they could become even more extraordinary.
Currently, this blue warship appeared compact, only about a meter long, resembling a child's toy. But it could expand tenfold—or even a hundredfold—at will.
"With Cloud Essence, all required components are forged according to blueprints. Each part is inscribed with runes and assembled in a precise formation. The most difficult part is engraving the runes and forming the formation arrays. We've experienced many failures during the crafting process," said Gongshu Lin, who stood nearby. As a master of mechanical arts, he was the obvious choice for this task.
Crafting a Seven-Colored Warship was no trivial matter—it was not a common vessel but a true Heavenly Vessel, akin to a celestial treasure. It could float through the skies thanks to the Cloud Essence, which made it lighter than a feather and gave it extraordinary speed.
While it could be powered by one's internal energy, this was inefficient. Thus, forming a core energy pool was essential.
The energy core of a Seven-Colored Warship was known as the Seven-Colored Celestial Pool. Depending on the ship's color, the corresponding Celestial Pool would differ. For the blue vessel, the pool was called the Azure Celestial Pool.
Its construction required special runic arrays and rare materials—not just Cloud Essence but also top-tier water-attributed treasures. The key ingredient here was the Watercloud Dragon Vein Stone, a treasure found only in the deep sea and acquired through a trade with the Dragon Palace. On land, it was exceptionally rare.
Using both Cloud Essence and the Watercloud Dragon Vein Stone, the Azure Celestial Pool was formed. Any error during the process would lead to energy instability and the destruction of the entire ship.
A warship equipped with the Azure Celestial Pool could absorb cloud and water energies from the heavens and earth, converting them into a continual power supply for the vessel.
"Excellent. But I need to test it myself to be sure," Yi Tianxing said with a nod.
No matter how difficult the process had been, as long as the result was successful, it was worth it.
"Your Majesty, please inspect it!"Gongshu Lin and Master Lu spoke with confidence. They had already conducted thorough tests—the current vessel was indistinguishable from the legendary version.
"Rise!"
Yi Tianxing pointed toward the blue ship. It instantly expanded to over ten meters in length. With a single step, he stood on the deck.
Immediately, he could feel the Azure Celestial Pool operating, continuously absorbing the world's water essence and converting it into energy, fueling the vessel's array system: the Seven-Colored Rainbow Cloudlight Seal.
The more energy it absorbed, the faster its speed.
Whoosh!
In a flash of blue light, the ship—with Master Lu and Gongshu Lin onboard—vanished from sight and appeared before a coastal port of Great Yi via the Rainbow Bridge. On the sea, the ship floated effortlessly.
Under Yi Tianxing's control, it continued to expand, drawing infinite water energy from the ocean through the Azure Celestial Pool. In moments, it had grown into a behemoth, its deck large enough to hold ten thousand soldiers.
"Truly miraculous," Yi Tianxing mused. "A Heavenly Vessel made of Cloud Essence really can grow without compromising structure. Incredible."
The blue vessel now shimmered with divine radiance, gliding across the sea with zero resistance—as if it were one with the water. It moved like a blue streak of light, slicing through waves with astonishing speed.
"This speed rivals light travel, perhaps even faster. With unlimited water energy in the sea, the power supply is endless. Even over long distances, it'll remain stable."
Yi Tianxing was impressed—no ordinary cultivator's light-flight could match this ship.
"But now it's time to test its attack power."
Heavenly Vessels weren't just fast—they had to pack a punch. The blue ship's weapon was the Sea God Trident.
On the main sail, an ethereal image emerged: a vast ocean with a mighty Sea God looming above it, exuding an oppressive, divine aura. One glance would invoke fear and reverence.
The Sea God's face was obscured, but in his hand was a giant blue trident, around which countless mystical visions swirled, as though the power of the entire ocean had gathered there.
This was the ship's divine combat technique.
Naturally, manifesting it wasn't easy—it had taken many failed attempts before succeeding.
With a thought, Yi Tianxing activated the technique. Massive energy surged from the Azure Celestial Pool into the sail. The image of the Sea God came to life, his eyes blazing with cold fury. Waves roared around him.
Crack!
The Sea God hurled the trident.
A gargantuan, illusory trident appeared over the ocean and struck down. The sea was split in two, waves surging high into the sky, forming a heaven-covering tsunami. Within it surged chaotic water forces—any being struck by them would be shredded to pieces, no matter how strong.
Water, though soft, could also be the hardest.
When unleashed, it was more terrifying than most powers.
In the blink of an eye, the giant tsunami took shape.
Wherever it passed, sea beasts wailed in terror. Upon contact, their bodies exploded into clouds of blood mist.
