The Supreme Immortal Aperture.
"So, can you tell me about my father?" Gu Yue Fangxiang looked at the Hairy Man Gu Immortal before him.
Standing beside him was a female immortal.
The Hairy Man Gu Immortal, Mao Shi'er, glanced at the female immortal before turning his gaze to Gu Yue Fangxiang.
This female Gu Immortal was none other than the Merfolk, Lian Kexin.
It turned out that after Gu Yue Fangxiang had successfully passed his tribulation and become a Gu Immortal, he returned to the Hairy Man Continent to visit his mother, who had remained in a comatose state — the former City Lord of Iron Thread City.
Lian Kexin had been guarding him during his tribulation, explaining the true face of this world to him, making Gu Yue Fangxiang understand: to save his mother, he would need to make sufficient contributions to this world, to the Great Love Immortal Venerable. Only then could he use the contributions earned to post tasks, inviting those Gu Immortals skilled in healing to come and treat his mother.
Furthermore, Lian Kexin told Fangxiang: this Hairy Man Continent is overseen by a Hairy Man Gu Immortal. If you wish to find your father, perhaps you could ask him.
Thus, under Lian Kexin's guidance, Gu Yue Fangxiang met Mao Shi'er for the first time and inquired about his father.
Mao Shi'er nodded. "Your father... I do know something. But that was a very long time ago. If you want to know, then help me with something first."
Gu Yue Fangxiang felt some hesitation and did not agree immediately.
Seeing this, Lian Kexin immediately spoke up: "Immortal Friend Mao Shi'er, young friend Fangxiang has only recently ascended. If what you would entrust to him is too great a burden, perhaps you should let it go."
Gu Yue Fangxiang immediately cast a grateful look toward Lian Kexin.
Mao Shi'er laughed heartily. "Immortal Friend Fangxiang carries Hairy Man blood in his veins — would I really bully someone weaker? Don't worry, this matter is simply about placing the Wandering Refining Nest."
"Oh, I didn't expect you've already finished refining that nest?" Lian Kexin was genuinely surprised.
Mao Shi'er said, "With the methods personally created by our Master, we Hairy Man Gu Immortals only had to follow the established procedures."
Then, Mao Shi'er turned to Fangxiang. "The Wandering Refining Nest is already complete. All you need to do is place it into the Refining Sea. That's far easier than refining the nest itself. If you can accomplish this, I'll tell you the information about your father."
Gu Yue Fangxiang couldn't make up his mind and instinctively looked toward Lian Kexin.
Lian Kexin smiled at him and gave a gentle nod.
"Alright, I'll do it." Gu Yue Fangxiang made his decision.
Mao Shi'er then transferred the Wandering Refining Nest into Gu Yue Fangxiang's Immortal aperture.
The first time Gu Yue Fangxiang laid eyes on the Wandering Refining Nest, he saw a peculiar structure as large as a mountain peak, yet shaped and structured like a honeycomb, filled with spaces of varying sizes within.
The nest was narrow at the top and wide at the bottom, entirely orange-yellow in color, with an island-like base that could float upon the sea, resisting fierce winds and massive waves with great stability.
"How marvelous!" Fangxiang employed his inspection methods, took one look, and his eyes went wide, his expression filled with shock.
Mao Shi'er chuckled, speaking with a tone of pride. "This was personally created by our Master, so naturally it is extraordinary. Every Wandering Refining Nest can be considered a prototype of a Secret Realm of Heaven and Earth. The nest contains countless Refinement Path Dao Marks — refining Gu inside it not only increases the probability of success but also reduces the cost of Gu refinement."
"Each nest can accommodate tens of thousands of Refinement Path Gu Masters, and even up to ten Refinement Path Gu Immortals. With a Refinement Path Gu Immortal presiding over it, the nest can produce Immortal Gu in an endless stream! Every Wandering Refining Nest can be seen as a supreme resource hub for the Refinement Path."
"Alright. Time is running short — you should set off immediately."
Fangxiang grunted in acknowledgment and immediately set off with Lian Kexin for the Refining Sea.
The Refining Sea was located at the center of the Small Eastern Sea. Compared to other sea regions, it was not large, but its value was beyond ordinary.
"This is a genuine Secret Realm of Heaven and Earth!" Through Lian Kexin's explanation, Fangxiang came to understand the preciousness of the Refining Sea below.
"Master truly is formidable! His methods are beyond imagination, like those of an immortal deity — he can even forge a Secret Realm of Heaven and Earth!" Fangxiang exclaimed in admiration, one after another.
The Refining Sea of today had been thoroughly perfected by Fang Yuan, becoming a true Secret Realm of Heaven and Earth in every sense!
In the past, the Langya Spirit had harnessed tribulations to collect Water Path Dao Marks, painstakingly creating the prototype of the Refining Sea. But when it came to Fang Yuan's hands, his efficiency in building the Refining Sea increased countless fold.
First, Fang Yuan was a Venerable, his strength far surpassing even Ancestor Long Hair, let alone the Langya Spirit.
Second, Fang Yuan was a Supreme Grandmaster of the Refinement Path. A present-day Supreme Grandmaster would inevitably be more powerful than one from the past.
Third, Fang Yuan possessed the Supreme Immortal Body — his Dao Marks did not conflict with each other, allowing him to employ methods from any path. He could directly use Water Path methods, which was far more convenient than what the Langya Spirit had been able to do back then.
Fangxiang quickly found the target location, but setting it up required constructing an Immortal Formation, the contents of which were far more extensive and difficult than he had imagined.
This was because the Wandering Refining Nest was not the only one — many others were already distributed throughout the Refining Sea.
Placing a Wandering Refining Nest was not as simple as merely dropping it in. It needed to be temporarily stabilized in position and also form certain connections with the surrounding nests.
Once the number of nests eventually reached the required threshold, the Immortal Formation would hum to life, and all the nests would drift ceaselessly along with the waves of the Refining Sea.
They were like brushstrokes of ink, painting upon the canvas of the Refining Sea. The Refining Sea helped the nests refine Gu, and when the Refining Sea was heavily depleted, the nests in turn served to replenish it.
This was already a vast and majestic system!
Under Lian Kexin's guidance and cooperation, Fangxiang began constructing the Immortal Formation.
Three days later, they had completed only ten percent.
"This won't do — it's far too slow." Lian Kexin immediately decided to spend some contributions and post a task to recruit help.
Before long, a Gu Immortal arrived.
