The two Pure Dream True Bodies entered the Supreme Immortal Aperture and ventured deep into the Little Green Heaven before settling down there for the time being.
The Supreme Immortal Aperture was similarly divided into five regions and nine heavens. Among all the Little Nine Heavens, the Little Green Heaven was the place where Fang Yuan had invested the least effort. As such, it had become the spot where Fang Yuan housed and stockpiled dreams.
Shadow Sect members Ying Wuxie, Miss White Rabbit, Hei Loulan, Fairy Miao Yin, and Bai Ningbing were all cultivating in seclusion within the Little Yellow Heaven.
The Battle of Langya was far too high in scale—almost every participant possessed Eighth Transformation combat power. Even variant human Gu Immortals had relied on super Gu Formations to take part in the battle. Once those formations were shattered, they had lost the ability to intervene.
At the critical moment, Fang Yuan still needed these people to form the ancient battle formation Si Tong Ba Da, so these Shadow Sect members had simply refrained from participating.
As for Fang Yuan's Sixth Transformation Time Path clone, it was currently at the northernmost tip of the Little Northern Plains.
"Hu!"
A soft sound rang out. With the Time Path clone placing the final mortal Gu, the Gu Formation sprang to life.
The area covered by the Gu Formation was vast, spanning tens of thousands of mu. The Gu that made up the formation numbered in the tens of thousands—mortal Gu ranging from the First to the Fifth Transformation, sorted into various categories. But the most numerous were Ice and Snow Path Gu. At the core were two Ice Path Immortal Gu, both stolen from a Snow Folk Gu Immortal and now refined for Fang Yuan's use.
At the center of the formation stood three Eighth Transformation immortal-grade Ice Path Crystal Essences!
Each Ice Path Crystal Essence was as large as a mountain peak.
They were entirely water-blue in color, with a crystalline texture, their surfaces riddled with holes of varying sizes. The holes were incredibly numerous, and from them, an endless stream of frost and cold mist billowed forth.
If left to diffuse freely, the vast quantities of Ice and Snow Path marks within the mist would spread outward, imprinting on the surroundings and altering the environment to create conditions suitable for the Snow Folk and Snow Monsters to thrive.
That was why Fang Yuan had previously planned to use the Ice Path Crystal Essence in his possession to build a Snow Monster production line—a pillar of his economy.
His original Ice Path Crystal Essence had been gained through his marriage alliance with Xue'er. Not long ago, he had slaughtered and plundered the Snow Folk clan beneath the Northern Ice Plain, acquiring two more Ice Path Crystal Essences.
"With these three Ice Path Crystal Essences, producing Snow Monsters will be effortless."
"As for this grand formation, I shall name it the Snow Crystal Formation."
After inspecting the formation, Fang Yuan's Time Path clone nodded with satisfaction.
Realms of comprehension were universal. Since Fang Yuan's main body possessed the Grandmaster realm in the Formation Path, his clone was the same.
This differed from the Shadow Sect members. Back then, Demon Venerable Spectral Soul had used soul fragments to create clones in order to deceive the heavens, and these clones each came with a fatal flaw in their realm of comprehension—every member was proficient in only a single Path.
Shadow Sect members, even if they crossed paths with Heavenly Court Gu Immortals, could never be recognized as clones linked to the Demon Venerable's main body. This was one of the reasons the Shadow Sect had been able to plant moles within the Heavenly Court.
Fang Yuan's Time Path clone, on the other hand, was extremely easy to expose. But Fang Yuan had no need to send the Time Path clone on external missions, infiltration operations, or assassination strikes. His objective differed from Demon Venerable Spectral Soul's. He had created the Time Path clone primarily to make full use of the Wisdom Halo.
And to calculate all manner of things within the Wisdom Halo, a high realm of comprehension was indispensable. One could not have both fish and bear's paw. Fang Yuan had made a wise trade-off in this regard.
The Snow Crystal Formation had naturally been set up single-handedly by the Time Path clone. Its primary function was to take the perpetual frost breath exhaled by the Ice Path Crystal Essences and distribute it evenly and continuously across every inch of the surrounding area, constantly transforming the local environment.
Of course, the formation also possessed monitoring and regulating capabilities.
"A pity that I am only a Formation Path Grandmaster and not a Great Grandmaster. A Grandmaster's realm lets one draw inferences from related fields, but a Great Grandmaster can directly utilize natural Dao marks. If I were a Great Grandmaster, setting up the Snow Crystal Formation would not require Ice Path Immortal Gu at all—mortal Gu and these three Ice Path Crystal Essences alone would suffice."
That way, Fang Yuan could have saved those two core Ice Path Immortal Gu and repurposed them for other uses.
Of course, Fang Yuan was a special case. He did not lack Immortal Gu, so it hardly mattered. Under normal circumstances, a Gu Immortal's grasp over Immortal Gu was extremely limited. If one used Immortal Gu to construct Gu formations, that Gu would typically be trapped within the formation and unavailable for anything else. From this alone, one could see the tremendous advantage of advancing to high Path realms—it helped Gu Immortals conserve their Immortal Gu!
After finishing the Snow Crystal Formation, the Time Path clone turned and flew away.
Though he was not an Earth Spirit and lacked teleportation abilities, with Immortal Gu in his possession, his flying speed was certainly no slouch.
Moments later, the Time Path clone had crossed several hundred li. Concealing his figure, he gazed down at the ground from high in the sky.
Below, a group of Snow Folk were making their way across the land.
These Snow Folk included both ordinary mortals and Gu Masters—all variant human slaves Fang Yuan had abducted from the Northern Ice Plains. Their numbers were sizable, numbering in the thousands.
Snow Folk slaves in the thousands were not uncommon in the Yellow Treasure Heaven. But this batch was far above the usual standard, because the proportion of Gu Masters among these Snow Folk was remarkably high. This was an utterly abnormal phenomenon. In the Yellow Treasure Heaven, this batch of Snow Folk could fetch at least ten times the usual price in trade!
Having been suddenly ripped away from the environment they had lived in for so long and thrust into the Supreme Immortal Aperture, these Snow Folk were naturally filled with terror and suspicion.
