There were also Mushroom People Gu Immortals.
Although Fang Yuan had not yet annexed the Mushroom People's Blessed Land, most of these Mushroom People had been relocated by him into the Supreme Immortal Aperture. The strongest among the Mushroom People Gu Immortals was Ke Xinhong, whose methods on the Path of Poison were extraordinary.
Moments later, the Fire Origin Grotto-Heaven side began to collapse in full rout.
Not only did they lack the numbers of Fang Yuan's subordinates, but even in one-on-one clashes among Seventh Transformation powerhouses, they were inferior to Fang Yuan's forces.
Fang Yuan's subordinates gave chase and seized the opportunity to kill even more Fire Origin Gu Immortals.
In the end, the few remaining Gu Immortals had completely lost their will to fight and wished to surrender, but Fang Yuan ordered them executed without hesitation.
What followed was the cleanup of the battlefield.
The Fire Origin Grotto-Heaven was primarily focused on the Path of Flame, so most of its immortal materials belonged to that Path as well.
Although the earlier ant plague had caused considerable losses, the Gu Immortals within the grotto-heaven had fought to the last to preserve their resources, and there were still many priceless materials remaining.
For instance, there were as many as twenty-eight Fire Coal Lakes, distributed across various locations throughout the Fire Origin Grotto-Heaven.
Each Fire Coal Lake was clearly positioned through meticulous planning, with numerous wonderful properties.
Fang Yuan had once constructed Fire Coal Lakes of his own, but even his best could not compare to a single one within the Fire Origin Grotto-Heaven.
These Fire Coal Lakes had long since established self-sustaining cycles. In the deepest depths of their centers, they could produce vast quantities of Fire Coal Stones at the immortal material grade.
Besides the Fire Coal Lakes, the Fire Origin Grotto-Heaven also contained a massive forest.
The Fire Date Tree Forest!
Fang Yuan also discovered several ancient Desolate Plants — Calamity Burning Wood.
These trees burned year-round, making it impossible for anything to approach. More formidable still, the Calamity Burning Wood would bring countless misfortunes and calamities upon any living being that drew near.
This was an immortal material that combined the Path of Flame with the Path of Fortune.
Those Two Heavens Grotto-Heavens under Fang Yuan all possessed varying amounts of Fortune Path immortal materials. The Fire Origin Grotto-Heaven was no exception.
Beyond these, Fang Yuan also harvested a large quantity of flames.
The most abundant was the Date Flame.
These flames were vermillion in color, clumped together in a ball, with an extremely restrained nature. Though they were immortal materials, even a mortal could hold them in bare palms without being scorched to ash.
In addition to Date Flame, there were also Phoenix Cry Fire, Pitch-Dark Fire, Ivory Flame, Firefly Flame, Flying Fire, Dragon-Snake Dancing Fire, and more.
What left Fang Yuan slightly disappointed was that despite the sheer number of these flame Gu materials, not a single one among them was the Nine-Transformation-grade Three Fires of Heaven, Earth, and Man.
The so-called Three Fires of Heaven, Earth, and Man were the pinnacle among all flames: the Heavenly Fire — Radiant Wheel Fire, the Earthly Fire — Azure Divine Stone Furnace Fire, and the Human Fire — Surging Wave Ascending Dragon Fire.
After cataloguing the immortal materials, the tally of Immortal Gu began.
The Immortal Gu obtained were few in number — only three.
One was a Path of Flame Immortal Gu, severely damaged. It had been an externally released Gu insect that Bing Yuan had managed to capture by luck.
The other two were both Ant Immortal Gu. One gleamed with a metallic sheen across its entire body, as large as a small hill, resembling crimson copper. The other was as small as a fingertip, its body greatly elongated, soft like a strip of white dough.
The Crimson Copper Immortal Ant could launch fireballs, while the White-Faced Immortal Ant could produce vast numbers of ants.
These were all products of the Legacy Poison Ant Calamity killer move.
The ants consumed the Gu materials within the Fire Origin Grotto-Heaven and would continuously advance and refine themselves. What started as mere mortal Gu could ultimately be refined into Immortal Gu.
But what kind of Immortal Gu they would become — even Fang Yuan himself could not predict.
However, from these two ants, he could barely discern their original forms.
The Crimson Copper Fire Ant had likely been an Arrow Ant originally. Arrow Ants could launch barbs from their mouthparts. After firing three barbs, an Arrow Ant would become extremely weakened, unable to even defeat a Worker Ant.
The White-Faced Immortal Ant was likely a Queen Ant. Queen Ants were enormous in size, possessing no offensive or defensive ability whatsoever, but they could rapidly produce Worker Ants, Soldier Ants, Arrow Ants, Armored Ants, and many other ant varieties.
The life essence of Legion Ants was merely that of vicious insects, but their strength could be elevated — from the ordinary beast tier, to the Beast King tier, then to Desolate Beast, Ancient Desolate Beast, and finally to the Prehistoric Desolate Beast tier.
Just like the Shadow Weaving Spider in the River of Time, which was a Prehistoric Desolate Beast. The Spotted Tiger Bee recorded in the Legend of the Human Ancestor was also a Prehistoric Desolate Beast.
However, after Wu Shuai's modifications, the ants produced by the Legacy Poison Ant Calamity had fundamentally changed in nature — they had all become Gu insects!
Though Gu insects also consumed food, they were carriers of Dao Mark fragments.
The value of a single mortal ant Gu far exceeded that of an ordinary insect ant.
Every one of these ant Gu was robust and powerful, brimming with tenacious vitality, fierce and combative. A hundred ant Gu could easily slaughter a hundred ordinary ants of equivalent rank.
The vast majority of Gu insects were extremely fragile, easily crushed with a pinch. But a select few possessed hard outer shells and tenacious life force.
For instance, the Serrated Golden Centipede that Fang Yuan had once used.
The refinement path for the Serrated Golden Centipede primarily branched in two directions.
One advanced into the Fourth Transformation Electric-Tooth Murder Centipede, and the other into the Diamond Flying Centipede, spanning the Third, Fourth, and Fifth Transformations.
When a Gu Master activated these two, the Gu insects would fly forth — the former to slice and slaughter powerful enemies, the latter to pierce through flesh and bone, burrowing inside to wreak havoc.
At the Immortal Gu level, this type of Gu insect also existed.
For example, the Sword Foot Dragon Centipede Gu.
