Chapter Fourteen: The Celestial Rainbow Vessel

Old Crab had also reached the Grandmaster realm. Originally, the Xuanyi Qingshui Technique was a human clan martial art, and the demon race progressed very slowly in cultivating it. Yang Nan selected a set of aquatic clan techniques from the He Luo Tianji Chart for him. Although Old Crab benefited greatly, he never uttered a word of thanks. In his heart, his life belonged entirely to the young master; having received the cultivation method, his very existence remained under the young master's command. Even if he were to ascend to immortality or sainthood in the future, he would still be a general under the young master—so why bother expressing gratitude?

Dieyi was an insect demon, and Lianyi a flower demon. Yang Nan also chose a set of cultivation techniques for them from the He Luo Tianji Chart. This time, the techniques differed from the Xuanyi Qingshui Technique, filling them with joy. With such superior methods, once they achieved Grandmaster status, they could officially become Yang Nan’s concubines, gaining legitimate status—surely a cause for universal happiness.

Only then did Yang Nan realize that the true treasure of the thirty-six He Luo Tianji Charts in his possession was not inferior to any innate spiritual treasure. As long as one possessed this set of cultivation methods, any demon in the world aspiring to ascend to sovereign or saintly status would be envious.

He had forcibly seized this treasure from the Blue Star Sovereign and captured the Lion Saint’s son—future troubles were truly endless.

A month swiftly passed. Ni Cai had long completed forging the Celestial Rainbow Boat, including the one required by Princess Long Yao. Two thousand demon soldiers, along with the shrimp and crab troops from the Dragon Palace, were tirelessly commanded by Huang Shan and Ni Cai. Ultimately, the task was accomplished.

All the magical treasures and artifacts Yang Nan had acquired were used in forging this Celestial Rainbow Boat. The sarira was forged by Ni Cai into the ship’s bow; whenever clashing with enemy magical weapons, it could emit a Buddhist light to protect the prow. The Blue Blood Sword was forged into a ram; this extraordinary weapon, made from Blue Blood Divine Iron, housed a dragon soul within, capable of devastating enemies like a raging storm.

All the various magical weapons Yang Nan had obtained along the way were melted down by Ni Cai and integrated into the boat’s structure—truly nothing was wasted.

The Xuanming Yinsha Banner was placed by Ni Cai at the ship’s prow to serve as a protective Yin spirit, and another was embedded along the hull to activate the power source pool beneath.

The hull was made entirely from Shui Luo silk, a celestial material neither metal nor fiber. After refinement, it became extraordinarily flexible yet incredibly tough—Yang Nan’s Yin Erosion weapon required several strikes to pierce it. The hull, made purely of Shui Luo silk, was impervious to water and fire, transforming into a magical treasure capable of agile flight and impact.

The seventy-two Dragon Extinguishing Stakes Yang Nan recently acquired were also not spared from Ni Cai’s hands. After Huang Shan’s ritual forging, the seventy-two stakes encircled an unnamed divine stele to form a mana pool, continuously fueling the Celestial Rainbow Boat with magical power. Each stake contained the soul of a fire dragon; when their seven distinct flames were unleashed and triggered by Ni Cai’s formation, the boat could travel thousands of miles in an instant, its speed as swift as lightning. When necessary, the stakes could even fly outside the boat, trapping and capturing enemies for refining!

With Ni Cai’s addition, Yang Nan finally consolidated the chaotic assortment of magical treasures and artifacts in his possession. Ni Cai laid out a massive Nine-Yuan Turtle Shell Formation on the boat, providing formidable defense, though it consumed immense spiritual energy. Yang Nan even emptied all the spirit stones he carried. Yet, the frenzied cooperation between Ni Cai and Huang Shan didn’t stop there.

They had arranged thirty-six Nine-Nine Return to One Thunder Formations throughout the entire Celestial Rainbow Boat, guided by the Demon Valley Thunder Order. These formations could instantly release immensely powerful purple heavenly thunder. Provided there was sufficient spiritual energy, dozens of terrifying heavenly thunders could strike down, obliterating even Grandmasters and Sovereigns alike, eradicating their souls.

However, the spiritual energy consumption of these thirty-six formations was colossal; for now, only a single strike was feasible. Unless Yang Nan could find a treasure with boundless magical power to supply them, it would be impossible to unleash eighty-one consecutive heavenly thunder strikes.

Having obtained this treasure, Yang Nan felt a great calm in his heart. Aside from his life-bound weapon and Yong’er, he only retained a single artifact—the impractical Binding Immortal Rope. After Ni Cai’s handling, Yang Nan’s wealth was nearly depleted, yet the Celestial Rainbow Boat’s existence far surpassed any artifact he had previously owned.

In battles between Grandmasters, power depended solely on the depth of spiritual energy and the strength of magical treasures. With this boat, Yang Nan’s strength would be greatly enhanced.

Having lingered at the Dragon Palace for over a month, although Princess Long Yao’s Celestial Rainbow Boat was inferior to Yang Nan’s, it was also remarkable after concentrating the Dragon Palace’s treasures. Seeing that everything was settled, Yang Nan bowed respectfully and bid farewell to Princess Long Yao.

Princess Long Yao’s expression darkened when she saw Yang Nan preparing to leave. “Why not stay a few more days, friend? Is the underwater Dragon Palace not worth lingering in?”

Her demeanor was markedly different from before, causing Yang Nan’s heart to leap. He smiled and said, “My dear wife is eager to return home to visit her father-in-law. I shall come to visit the princess another day.”

Long Yao nodded. “Brother Yang, take this token. If you ever need the help of the aquatic clans, this token will make matters easier within the Four Seas.”

Yang Nan was momentarily taken aback, then reached out to accept the warm jade token, which bore the image of a white dragon and the name Long Yao—presumably her identification token. Holding this hot potato made Yang Nan quite embarrassed, but beside him, Fang Qingyan took it with a smile. “Since my sister is so kind, I shall accept it. I promise to return to the West Sea one day.”

Yang Nan was surprised but saw that his wife’s gaze was indifferent, as if unaware. He shook his head and did not dwell on it.

The Celestial Rainbow Boat soared into the sky, transforming into a streak of light cutting through the water, heading straight toward the horizon. The boat was magnificent, like a vessel from beyond the heavens, flying swiftly through the air. Sitting within, Yang Nan activated the Dragon Extinguishing Stakes in the mana pool, which instantly spewed seventy-two flames. Along with the formation’s activation, the boat sped forward. Ni Cai looked proudly at the treasure he had painstakingly forged, while Huang Shan wore an expression of great accomplishment.

Over the past month, they had combined the power of countless demons to forge such a powerful treasure, truly a matter of great pride.

Old Crab, Great Roc, and other demon soldiers marveled at the Celestial Rainbow Boat’s versatility. It could expand or contract, with a spacious cabin akin to a small city, easily accommodating ten thousand souls. Ni Cai’s mastery of formations was extraordinary, and Yang Nan secretly marveled at the treasure he had brought back.

The boat could fly autonomously with minimal control. At the center of the mana pool, the Dragon Extinguishing Stakes and the unnamed divine stele formed the core. This stele’s spiritual energy was peculiar—indestructible and able to contain infinite energy. When the formation was activated, it continuously absorbed the world’s spiritual energy, converting it into mana within the pool. The entire Celestial Rainbow Boat resembled a celestial mountain retreat, with spiritual energy converging and immortal clouds drifting, highly conducive to cultivation.

Old Crab, Great Roc, and the other demon soldiers, newly equipped with first-rate cultivation techniques and with such a magical treasure on hand, found a vacant spot beside the mana pool to sit and cultivate.

Ni Cai had yet to fully comprehend the divine stele and now sat before it, pondering seriously.

Yang Nan steered the divine vessel flying over the sea, feeling immense pleasure. Such a treasure could easily harm enemies or aid escape—unless a formidable expert like the Blue Star Sovereign appeared, even a Grandmaster would be hard-pressed to prevail.

Yang Da and Yang Er guided the way over the sea. Although the Southern Continent was thousands of miles from the West Sea, the Celestial Rainbow Boat’s speed meant they would arrive soon.

The West Sea stretched vast and boundless. After demonstrating the boat’s many mystical features in the air, Yang Nan descended to the sea surface, letting the demon soldiers take over navigation. Under the leadership of the Shrimp Commander, the two thousand demon soldiers enthusiastically manned the boat, thoroughly enjoying themselves.

In the boat’s enormous cabin, Fang Qingyan and two other women unpacked the gifts Princess Long Yao had given—pearls and coral ornaments filled the entire cabin. Yang Nan looked at this collection of feminine treasures and smiled wryly. Even for cultivators, a woman’s nature remained unchanged.

“Husband, these are gifts from Princess Long Yao. Look, aren’t they beautiful?” Fang Qingyan blushed shyly, carefully holding a massive handful of pearls before Yang Nan. She had been inseparable from Long Yao during their time in the Dragon Palace, somewhat neglecting her own husband.

Yang Nan chuckled, “Qingyan, you are a cultivator. There is a saying: pearls are as common as dirt, gold as abundant as iron. If you love these things so much, why not gather some yourself from the mountains and seas someday?”

Seeing her husband unperturbed, Fang Qingyan breathed a slight sigh of relief and smiled. “It’s not that I covet wealth, but after visiting my parents, I don’t know when we will meet again. So I wanted to bring plenty of gifts to comfort them.”

Yang Nan nodded and suddenly realized that as a son-in-law returning to his wife’s family, it would be inappropriate to come empty-handed.

“Thank you for your thoughtfulness, my lady. If you hadn’t mentioned it, I would have returned to meet my in-laws empty-handed. They might have thrown me out like a worthless son-in-law,” Yang Nan said with a mischievous wink.

Fang Qingyan shook her head seriously. “Husband, you are no worthless son-in-law. Your lofty ambition surpasses ordinary men.”

Yang Nan was moved by her earnest expression. He gently embraced her slender waist and kissed her tender cheek. Sent on this mission to descend the mountain, whether dealing with worldly affairs or mortal desires, he need not feign solemnity.

Dieyi and Baiyi, the two women, watched the couple’s sweet affection and giggled. Although Fang Qingyan had been married to him for several months, she was still unaccustomed to public displays of affection. She gently wriggled free from Yang Nan’s embrace. Yang Nan turned with a hearty laugh. “You two little girls, what are you laughing at?”

Baiyi laughed, “Master and madam are so loving; if you both ascend together one day, you will be the envy of all immortal couples.”

Yang Nan pinched her delicate nose. “If you don’t work hard, when I become an immortal, I’ll throw you out of the celestial realm!”

His joke made Baiyi blush with both shyness and joy. She nodded firmly. “Master, Baiyi will follow you faithfully, whether to heaven or earth, I will always be by your side!”

Yang Nan stroked her blue hair affectionately and nodded. “Very well. You all should organize these things; I shall go cultivate.”

Suddenly, Fang Qingyan looked up and quietly said, “Husband... what about that Sister Long Yao...?”

Seeing that she indeed brought up the matter, Yang Nan waved his hand with a smile. “You asked to receive that token yourself, so it’s not my concern. You’ll have to handle that on your own!”

Fang Qingyan was about to argue, but Yang Nan had already left the cabin laughing heartily...
