The income generated by Cremation Mushrooms, Black-and-White Fire Bears, Flame Marsh Grass, Red Emperor Earth, and Red-Horned Antelope was already considerable. Yet even after combining more than ten resource points, their annual profits would only amount to a few dozen immortal essence stones.
Netherfire Dragon Pythons were different. Once their population reached a sufficient scale, they alone could surpass the combined value of many Mortal Grade resource points.
Of course, such profits were not easily obtained. Like many species with dragon bloodlines, Netherfire Dragon Pythons reproduced at an extremely slow rate. Reaching that scale would require thousands of Netherfire Dragon Pythons.
For this reason, Lin Yan spent ten immortal essence stones to purchase several hundred Netherfire Dragon Pythons as breeding stock. The returns would not appear anytime soon, but he was in no hurry.
After settling the affairs of the Southern Li Fire Plains, Lin Yan shifted his attention toward the Northern Flame Desert.
The primary purpose of developing that region was simple.
Fire oil. After all, it was the main food required by Oil Flame Immortal Gu.
For the Northern Flame Desert, Lin Yan chose only two species: Fire Lizards and Flaming Thorns. The arrangement was simple and practical, mainly intended to adapt to the harsh desert environment.
Flaming Thorns served as food for the Fire Lizards. The Fire Lizards themselves preferred burrowing through the sand, and after death, their corpses occasionally transformed into fire oil under the influence of the region's unique flames.
The Western Molten Flame Mountains were even easier to develop. Lin Yan only introduced Fire Lizards there. This species fed on ash, sulfur, and Fire Ember Stones, all of which were abundant throughout the region. Their resistance to flames was also exceptionally high, allowing them to thrive within the Molten Flame Mountains.
As for the Eastern Thunderous Hills, Lin Yan selected only the famous Lightning Struck Wood.
This type of tree was repeatedly destroyed by lightning, yet each strike tempered it further instead of killing it. In an environment filled with constant thunder and lightning, it possessed extraordinary growth potential.
Because his understanding of Thunder Path remained limited, Lin Yan chose a more cautious approach toward that region.
After all, his immortal essence stones were not limitless. Most of his reserves had already been invested into the Blessed Land. The remainder needed to be reserved for killer move deductions, Gu refinement, and unexpected situations.
Even so, the results were already considerable. More than ten new species had been introduced into the Flame Sovereign Blessed Land, while the framework of several ecological chains had gradually taken shape.
Lin Yan silently calculated in his mind. If everything proceeded smoothly, then after three years within the blessed land, the first batch of investments would begin yielding returns.
By then, the Flame Sovereign Blessed Land would finally enter a period of rapid growth.
After settling the newly introduced plants and beast groups, Lin Yan once again returned his attention toward his killer moves.
With Lin Yan Grandmaster attainment in Flame Path, his progress was remarkably smooth. Almost every three days, he was able to complete the improvement of an immortal killer move.
Following Crimson Virtue True Body, he successively improved Three Flavour Otherworldly Flame and Raging Flames Engulfing the Body, both centered around Three Flavour Otherworldly Flame Immortal Gu. He also completed the improvement of Prairie Fire, using Oil Flame Immortal Gu as its core.
Each immortal killer move could coordinate hundreds of Gu worms simultaneously and possessed formidable power.
However, Lin Yan remained clear-headed. The reason for such rapid progress was not solely his attainment. Long before becoming a Gu Immortal, he had already spent years researching these killer moves. The frameworks were complete, and many difficult problems had already been solved.
Immortal Ascension merely allowed him to refine and perfect them at an astonishing speed. By now, nearly all of his previous accumulation had been transformed into actual results.
Only a single killer move remained unresolved—Rebirth Through Fire. Unfortunately, it still lacked a suitable Immortal Gu to serve as its core, making it impossible to complete for the time being.
As for Mystic Sun Myriad Flames Great Handprint presented a different problem. Unlike Rebirth Through Fire, it did not lack a core Immortal Gu. Instead, it required several Immortal Gu to work together within the same killer move, making its structure extraordinarily complex. The amount of work involved was immense, so Lin Yan temporarily set this matter aside.
The same applied to Crimson Virtue True Body and his other immortal killer moves. Although their power could be increased further by incorporating additional Immortal Gu, Lin Yan had no intention of doing so for the time being.
After all, immortal killer moves involving multiple Immortal Gu were typically the domain of Rank 7 Gu Immortals.
For a newly advanced Rank 6 Gu Immortal, the burden was simply too great.
Not only did such killer moves place tremendous strain on the mind, but every activation consumed a large amount of immortal essence. Unless absolutely necessary, they were unsuitable for prolonged combat.
Lin Yan therefore chose a more steady approach.
His immediate goal was to ensure that every Immortal Gu he possessed had a corresponding immortal killer move. After that, he would gradually expand them into a complete system of offense, defense, movement, healing, investigation, and support.
Only after establishing a solid foundation would he begin attempting to combine multiple Immortal Gu into the same killer move.
Advancing step by step from simple to complex was both safer and more efficient.
Of course, if Lin Yan possessed enough Immortal Gu, many of these intermediate steps could be skipped. A truly powerful multi Immortal Gu killer move was often capable of replacing an entire combat system on its own.
