The entire process of a Gu Master refining Gu was extremely secretive. If someone watched it, they would undoubtedly leak the secret Gu recipe or the Gu Master's unique techniques.
"Of course. This was also one of the terms of our original agreement." The Lang Ya land spirit readily agreed, taking Fang Yuan by surprise.
Fang Yuan raised his eyebrows, starting to understand.
Back then, Long Hair Ancestor had failed to refine the "Void Escape Gu", wasting all the materials that Thieving Heaven Demon Venerable had painstakingly accumulated over his entire life. Many of these Gu materials were extremely rare, and even the Demon Venerable had only managed to collect them through sheer luck.
Thieving Heaven Demon Venerable was a Rank Nine Demon Venerable. To make up for his losses and salvage his own reputation, Long Hair Ancestor promised to refine an Immortal Gu for him.
Allowing Thieving Heaven Demon Venerable to observe the entire refining process was both a way to deliberately leak the secret recipe as compensation, and a method to prove his innocence—*You saw the whole refining process. If I fail, I did not sabotage it intentionally!*
But in Fang Yuan's current situation, he had no such worries.
A land spirit was formed by the power of heaven and earth of a blessed land, combined with a Gu Immortal's obsession at the moment of death. It lacked the malicious intentions of humans and was straightforward and open.
However, the Lang Ya land spirit was transformed from the number one Refinement Path Immortal of ancient times, Long Hair Ancestor. Although he had lost most of his memories, he still retained most of Long Hair Ancestor's talent and attainments in the Refinement Path.
Observing the land spirit refine Gu was immensely beneficial for Fang Yuan.
"I've refined the Second Aperture Gu before. This time, I'll see what the Lang Ya land spirit has up his sleeve. I can learn from his experience to make up for my own shortcomings. Perhaps I might even catch a glimpse of the dazzling brilliance that Long Hair Ancestor displayed through the ages." Fang Yuan was full of anticipation for this Gu refining session.
The Lang Ya land spirit gently waved his hand and teleported him to a great hall.
This hall was incredibly vast, covering at least ten li in circumference. It was fully equipped with everything: bronze tripods, red iron furnaces, painted pottery vats, and even kilns.
Gu Masters sometimes needed vessels to aid them when refining Gu.
The vessels displayed in this hall were like a comprehensive exhibition, making even Fang Yuan feel like his horizons were being broadened.
Although he had five hundred years of experience from his past life and had undergone multiple rebirths, he had actually spent three hundred years wandering in misery. He only had about two hundred years of dominating the world and achieving greatness.
During this time, although he had extensively dabbled in other Gu paths, he had to resist earthly calamities, manage his forces, and refine Immortal Gu. With his attention divided, the foundation he had accumulated in the Refinement Path could make him proud among mortals, but among Gu Immortals, he was only at a second or third-rate level. Compared to an existence like Long Hair Ancestor, he was far inferior.
"This is my Earth-C No. 3 Refining Hall." The Lang Ya land spirit introduced it calmly. Upon hearing this, Fang Yuan's expression changed slightly.
The land spirit would not lie to him. Such a hall was merely one of the Refining Halls in the Lang Ya Blessed Land!
Earth-C... just how many places like this were there in this blessed land?
Just then, the land spirit waved his hand again.
In an instant, thousands of Mao Min appeared out of thin air in the hall.
The Mao Min were teleported over. They were stunned for a moment, then prostrated themselves on the ground and chanted in unison, "The Mao Min pays respects to the Lang Ya Old Immortal!"
Their voices were perfectly synchronized, echoing through the hall.
A trace of a loving smile appeared on the Lang Ya land spirit's face. "Children, rise."
He waved his hand again, distributing the prepared refining materials. "Today, we will refine an Immortal Gu. Follow the recipe I have given you."
It was clear that the Mao Min had experienced this more than once or twice.
Upon hearing that they were refining an Immortal Gu, the Mao Min stirred, excitement showing on their faces.
But soon, they calmed down, began to study the Gu recipes in their hands, and started refining.
Thousands of Mao Min refining Gu simultaneously—this was not the first time Fang Yuan had seen such a scene.
Among variant humans, the Mao Min were the most skilled at refining Gu, born with the talent. According to the "Legends of Ren Zu", in ancient times, the Mao Min had already begun refining Gu on a large scale. They even tied up Ren Zu's eldest son, Tai Ri Yang Mang, attempting to kill him to refine the Eternal Life Gu.
When Mao Min refined Gu, they mostly relied on their talent and inspiration, acting freely without the contrived techniques of human Gu Masters.
At the level of Gu Immortals, far surpassing mortals, they often raised some Mao Min to help refine Gu. In his past life, Fang Yuan had also raised Mao Min.
But his was the Blood Sea Blessed Land, an extreme environment. After several batches of Mao Min died, his interest in raising them waned.
After becoming a Gu Immortal, Fang Yuan had gathered the Mao Min under his command to refine a large number of Gu worms for his demonic sect forces.
Precisely because he had personal experience, looking at them now, he immediately noticed the exceptional qualities of this batch of Mao Min.
These Mao Min were excellently nurtured.
Looking at their fur, each one was glossy and clean. Their eyes were bright, their faces were rosy. It was clear that their living environment was extremely good, and they had not suffered any mistreatment from the Lang Ya land spirit.
More importantly, these Mao Min were full of intelligence, their movements were agile, and every single one of them was a seasoned veteran, a true expert at refining Gu.
During the refining process, one or two old Mao Min even offered suggestions, modifying the secret recipe!
Seeing their casual and skillful movements, even Fang Yuan's heart trembled with excitement.
If a group of Mao Min like this were put up for sale in Treasure Yellow Heaven, they would be the finest of fine slaves. They would emit a treasure light at least seven zhang high, and Gu Immortals would fiercely fight over them.
The attainments of these Mao Min were astonishingly high; most of them were Refinement Masters. A few of them, precisely the old Mao Min who had made the suggestions, were already Refinement Grandmasters!
As for Fang Yuan himself, he could barely be considered a Master at present.
With such a heavyweight lineup as his assistants, the progress of the Gu refining was naturally more than ten times faster than when Fang Yuan had done it at San Cha Mountain.
