Over the next several days, Fang Yuan's footsteps covered virtually every corner of the Black Fan grotto-heaven.
His divine sense enveloped the surroundings at all times, constantly observing and carefully studying everything.
Sometimes, Fang Yuan felt as though Black Fan were guiding him from across the long river of time.
The Black Fan true inheritance contained meticulous explanations, and the grotto-heaven before him was a living example—tangible, something he could touch, excavate, and examine. Whenever he found signs of changes, Fang Yuan would perform soul searches on the captive Gu Immortals. This gave him even deeper understanding of the rise and fall of countless species and their secrets across the vast stretch of time.
Black Fan's talent filled Fang Yuan with both emotion and admiration, and he benefited enormously from it. When it came to constructing the supreme blessed land, Fang Yuan now had a wealth of new ideas.
Once Fang Yuan was confident that he had thoroughly familiarized himself with the Black Fan grotto-heaven, he set about relocating everything.
First came the sky crystals.
The first restricted area of the grotto-heaven was the sky crystal breeding pool.
This pool was built high in the sky, spanning a hundred li in area, surrounded by layers upon layers of Gu formations. But the sky crystals themselves occupied only a small patch right in the very center.
The sky crystals produced naturally by the grotto-heaven had a faint cyan-green hue.
The appearance and color of sky crystals varied depending on the region of origin.
Fang Yuan relocated this breeding pool into his own small azure sky.
"It's a pity this pool can only produce sky crystals within a grotto-heaven. My supreme blessed land is still only a blessed land—if I place it there, it won't function. Still, the pale cyan sky crystals in the pool, combined with most of that sky crystal eagle nest, should last five or six years."
Fang Yuan did a quick calculation. With this income, feeding the high-tier Sky Eagles wouldn't be a problem.
Sky crystals were still rather hard to purchase in the Treasure Yellow Heaven.
The second restricted area was underground.
It was an enormous cavern.
Inside grew a massive number of stone stalactites, the most valuable among them being the lotus-stone stalactites—rare even in the outside world, yet here they grew in abundance.
Fang Yuan spent considerable effort excavating the entire cavern. He moved it into the supreme blessed land and buried it in the small Southern Border.
Fortunately, he possessed the Mountain-Moving Immortal Gu. Without it, handling this second restricted area would have been far more difficult.
"Though with this, the stalactites will draw upon the earth qi of my supreme blessed land to grow, which will inevitably accelerate the loss of earth qi. I'll need to seat the blessed land and replenish the earth qi at regular intervals."
Beyond these natural resources, there were also ancient desolate plants and ancient desolate beasts.
Among the ancient desolate plants was a Walking Meat Tree.
This tree was a rare strength-path plant that grew in the Black Sky.
To cultivate it, Black Fan had specifically cordoned off a section of the grotto-heaven to create a state of absolute darkness.
Around the Walking Meat Tree, Black Fan had meticulously laid out an entire ecosystem to ensure its stable survival.
The tree's branches were like thick, supple octopus tentacles. A single light flick could send a desolate beast flying.
Fang Yuan had seen one before in the Star-Studded grotto-heaven. Encountering a second one now, he couldn't help but feel a twinge of emotion.
He had once wished to obtain a Walking Meat Tree, because he could use the Effort-Bearing Immortal Gu to increase his own strength-path dao marks. But now he had the tree, and the Effort-Bearing Immortal Gu had been destroyed. Things truly didn't always work out as planned.
Fang Yuan placed the Walking Meat Tree in the small Black Sky of his supreme blessed land.
The power of the supreme blessed land was beginning to show itself gradually. Black Fan had needed to create elaborate conditions to cultivate the Walking Meat Tree. Fang Yuan didn't need any of that. The environment inside the small Black Sky was somewhat similar to the true Primordial Black Sky, and after being moved there, the tree seemed almost excited, its branches stretching out contentedly.
Because he had Black Fan's specialized techniques, relocating these ancient desolate plants was effortless for Fang Yuan. Everything went smoothly.
The same was true for the desolate beasts and ancient desolate beasts living in the grotto-heaven.
By following the methods laid out in Black Fan's true inheritance, Fang Yuan could guide the desolate beasts and ancient desolate beasts, leading them obediently into his own blessed land.
It was worth noting that among the ancient desolate beasts in the grotto-heaven, there were three Heavenly Cripple Dogs.
The pity was that Fang Yuan needed desolate beasts of the canine variety, not ancient desolate beasts. He needed canine desolate beast droppings to feed the sixth-transformation Luck Management Immortal Gu.
But these three Heavenly Cripple Dogs weren't entirely without use.
If in the future Fang Yuan upgraded the Luck Management Immortal Gu from the sixth to the seventh transformation, the feed requirements would change. At that point, the droppings of the Heavenly Cripple Dogs would come in handy.
Fang Yuan's relocation was highly efficient, and throughout the entire process, the Yellow Bell Heavenly Spirit silently accompanied him.
As the master of the grotto-heaven, every action he took received only support and cooperation from the Heavenly Spirit—never any resistance.
After a full half-month, Fang Yuan finally emptied the entire Black Fan grotto-heaven.
He didn't even spare the bare Immortal Succession Mountain, moving it into the small Southern Border.
Originally, the Black Fan grotto-heaven had been home to a large number of Gu Masters and mortals.
These were all descendants of the Black family's sinful immortal bloodline.
Fang Yuan killed them all, collecting their souls to nourish the Soul-Sweeping Mountain.
One thing that left Fang Yuan somewhat regretful was that the grotto-heaven had no aberrant humans living within it.
When a grotto-heaven or blessed land was developed to a certain stage, the Gu Immortal would raise aberrant humans inside. Black Fan had possessed the ability to do so, but ultimately had not.
Despite the lack of aberrant humans and the fact that many conventional cultivation resources within the grotto-heaven had been consumed in vast quantities by its resident Gu Immortal, Fang Yuan's harvest was still enormous!
The myriad resources of the Black Fan grotto-heaven instantly enriched the supreme blessed land, sweeping away its air of desolation and causing it to begin radiating with life.
