Lin Yan turned his attention to the two Rank 6 Gu Immortals imprisoned within his immortal aperture. Looking at them, he could not help but feel a trace of regret.
Capturing two Rank 6 Gu Immortals should have been an enormous harvest. Unfortunately, he possessed neither a soul-searching method nor a way to steal Immortal Gu from their immortal apertures. Otherwise, the gains from this battle would have been immeasurable.
The two Mo Family Gu Immortals could not be killed either. It wasn't because Lin Yan feared the Mo Family. Rather, until Fang Yuan's rebirth, he had no intention of triggering an even greater butterfly effect.
The same concern applied to the Huang Family. Had Lin Yan not been concerned about changing Han Li's fate and causing a massive shift in the future of the Western Desert, he would have long since moved the entire Family into his blessed land and left this place.
Fortunately, there were only two years and five months left until Fang Yuan's rebirth. He only needed to endure a little longer. After that, he would no longer have to hold back.
Looking at the two Gu Immortals, a cold smile appeared on Lin Yan's face.
Since he couldn't kill them for the time being, he would make the Mo Family pay the price instead. If they wanted these two Rank 6 Gu Immortals back alive, they would first have to hand over a Flame Path Immortal Gu.
Of course, given the arrogance of super forces, the Mo Family would never agree so easily. He had to maximize his gains while preventing the conflict from escalating into an irreconcilable feud.
A moment later, Lin Yan thought of a solution. He would find a third party to negotiate between the two sides. With that in mind, he immediately sent messages to Sun Cu and Tang Fangming.
The former was a well-known Loose Cultivator who frequently dealt with the righteous path, making him an ideal intermediary. The latter was a Gu Immortal from a super force. If he stepped forward, the Mo Family would naturally become more cautious and more willing to negotiate.
After making the necessary arrangements, Lin Yan no longer concerned himself with the matter. He sent his divine sense into Treasure Yellow Heaven and listed the specialties of his blessed land for sale, including Netherfire Dragon Pythons, Black and White Fire Bears, Flame Wolves, Red Earth, fire oil, and many other goods. The selection covered beast groups, vegetation, Gu worms, and various Gu materials.
Before long, more than a dozen Gu Immortal divine senses approached. After several rounds of negotiation, batches of goods were sold one after another.
The Netherfire Dragon Pythons, Red Earth, fire oil, and Gu worms sold the fastest. They were followed by the Flame Wolves, Black and White Fire Bears, Blazing Algae, Cremation Mushrooms, and various other materials. Only the Red Horned Antelopes proved difficult to sell, despite being the largest beast group.
After completing several transactions, Lin Yan's reserve of immortal essence stones quickly reached two hundred. His financial situation immediately became much more comfortable.
"The blessed land still needs a third batch of beast groups and vegetation. Only then can its ecological chain be gradually completed. According to my estimates, the entire process should take around six years."
Lin Yan calculated silently. A truly well-developed blessed land had one obvious characteristic—it rarely produced surplus beast groups or vegetation for sale. Instead, every species formed part of a stable ecosystem, supporting and restraining one another. Given enough time, immortal material resource points could even form naturally.
Even with the foundation of a Ten Extreme Physique, achieving this was far from easy. It required countless adjustments, practical experience, and repeated failures before the ecosystem could finally stabilize.
Lin Yan browsed through the various plants and beast groups available in Treasure Yellow Heaven. Without hesitation, he spent immortal essence stones to purchase cultivation insights related to blessed land management. After careful consideration, he finally made his decision.
For the Li Fire Plains, he introduced five or six kinds of vegetation, including Red Cloud Flower, Fire Beard Grass, Rehmannia, and Fire Jujube Tree.
Some competed for resources, some broke down dead organic matter, while others formed mutually beneficial relationships, gradually completing the ecological chain.
Fire Beard Grass and Flame Marsh Grass occupied the same ecological niche, but different beast groups fed on them. Red Cloud Grass helped regulate the dry climate, reducing competition between the two and serving as a natural buffer.
Rehmannia formed a symbiotic relationship with Cremation Mushroom, while Explosive Fungus grew by attaching itself to Provoke Fire Bamboo. Beginning with these mutually dependent species made it much easier to establish a stable ecosystem. Even if changes occurred later, they were unlikely to spiral out of control.
As for beast groups, Lin Yan introduced White Yang Elephants and Red Oxen, both of which fed on Fire Beard Grass. He also added powerful predators such as Blazing Lions to compete with the Flame Wolves and Black and White Fire Bears.
The northern Flame Desert received far less attention for the time being. Only three new species were added: Yang Fire Willow, Red Foxes, and Leaping Fire Rabbits. His current focus remained on developing the southern region.
Among them, Yang Fire Willow stabilized the soil, retained moisture, and would gradually create small oases throughout the desert, laying the foundation for future expansion. Meanwhile, Red Foxes preyed on Leaping Fire Rabbits and fire scorpions, strengthening the local food chain.
The western Molten Flame Mountains received seven or eight additional species of vegetation and beast groups, all capable of thriving in extreme volcanic environments. These included Volcanic Worms, Red-toothed Centipedes, Coal Vines, and several others, gradually completing the region's volcanic ecosystem.
The seller had confidently guaranteed that these species could survive and reproduce on their own. Lin Yan decided to trust that judgment for now. He made almost no adjustments, simply scattering them throughout the mountains and letting nature take its course. If they adapted successfully, the future returns would be enormous.
Finally, he turned his attention to the eastern Thunderous Hills. Since lightning-struck wood was the region's greatest advantage, he built the surrounding ecosystem around it. He introduced Lightning Ball Duckweed, which drifted through the air, Lightning Accumulation Grass that lived in symbiosis with the trees, and Electric Inducing Fungus that grew deep underground, forming a complete three-dimensional ecosystem.
In total, Lin Yan spent more than thirty immortal essence stones. After arranging every region of the blessed land, he finally let out a long breath.
"I just hope the losses won't be too great."
