An Immortal Gu House suddenly appeared, spanning the battlefield.
It resembled a mountain, though not particularly tall. Its body was divided into distinct tiers from bottom to top, with smooth surfaces. In this way, it also resembled a tower, formed by stacking dozens of giant drums of decreasing size. The entire Immortal Gu House was yellowish-brown, with a layer of hazy dust and sand blanketing its surface, giving people an intense feeling of weight and security.
Eighth Transformation Immortal Gu House — Secure Earth Heavy Mountain Fortress!
This Earth Path Immortal Gu House had been Fang Yuan's unexpected bounty from exploring the Dream Realm. It differed from the vast majority of Immortal Gu Houses in a fundamental way: this one did not have a single core Gu, but was instead built around Immortal Gu killer moves as its core.
The Secure Earth Heavy Mountain Fortress had three core killer moves. The most central was Accumulate Earth into Mountains.
This move was quite peculiar. It could not be used for offense, nor did it possess any teleportation, healing, or other such powers. Under this move, a Gu Immortal could freely arrange Earth Path Gu Insects, allowing them to self-assemble into an Immortal Gu House — even if the Gu Immortal activating the killer move had absolutely zero attainment in Formation Path!
To master this killer move was to master the root of the Secure Earth Heavy Mountain Fortress!
As such, every Secure Earth Heavy Mountain Fortress would have a different appearance. Even the same fortress would produce different forms and variations in power depending on which Earth Path Gu Insects were added to it.
Fang Yuan had built the Secure Earth Heavy Mountain Fortress a long time ago. He had obtained the complete construction blueprints from the Dream Realm and acquired a large number of Earth Path Immortal Gu from sources like the Azure Dragon Whale. In truth, he had already possessed this Eighth Transformation Immortal Gu House even before the Destiny Battle!
Now that Fang Yuan brought out the Secure Earth Heavy Mountain Fortress, the tide of battle shifted immediately.
Demon Venerable Spectral Soul's assassination attempt against Fang Yuan proved futile once more. Lu Weiyin, Qing Chou, and others struck in succession, forcing him to deal with them first.
"I had thought Fang Yuan was merely bluffing before. He was pressured so hard by me that he had no choice but to abandon the Dragon Palace and the Ten Thousand Year Flying War Chariot. But now it seems he truly intended to lure me into an ambush!" Demon Venerable Spectral Soul's heart grew somewhat heavy.
Honestly, Fang Yuan's act of abandoning two Immortal Gu Houses had greatly lowered his guard. After all, both the Dragon Palace and the Ten Thousand Year Flying War Chariot had been destroyed one after another — it was hard not to feel that Fang Yuan had reached a dead end.
He never expected that Fang Yuan had hidden such a trump card!
Lu Weiyin was also startled, thinking to himself: Fang Yuan was willing to pay such a heavy price to lure Spectral Soul in. Was this a show of trust? Or a test in their first collaboration?
In truth, Fang Yuan had no other choice.
Although he had always kept the Secure Earth Heavy Mountain Fortress in reserve, it had a major flaw. Its flight speed was far too slow! If there were an Immortal Gu House speed ranking, Fang Yuan's Secure Earth Heavy Mountain Fortress would undoubtedly be dead last, without any suspense.
Frankly speaking, the Secure Earth Heavy Mountain Fortress was the turtle among Immortal Gu Houses. Its movement was so sluggish it was only marginally better than a Gu formation — truly pathetic. But every gain came with a loss. While the Secure Earth Heavy Mountain Fortress had a critical deficiency in speed, its defensive capabilities were terrifyingly strong!
If Demon Venerable Spectral Soul, Lu Weiyin, and the others had known the fortress's strengths and weaknesses, they would have understood some of Fang Yuan's true position.
If Fang Yuan had deployed the Secure Earth Heavy Mountain Fortress during the earlier fighting, he would never have gotten far. He would have been reduced to a sitting duck, pummeled by Spectral Soul and the others. Though Fang Yuan might have gained a brief period of safety, the other factions would have had even more time to mobilize and assemble their forces to destroy him.
Fang Yuan could not afford to stay in one place for long. This was Central Continent, the territory of Heavenly Court. Even in decline, the Ten Great Ancient Sects still held their ground like tigers and dragons!
But now that Fang Yuan deployed the Secure Earth Heavy Mountain Fortress, the effect was night and day.
Demon Venerable Spectral Soul simultaneously fended off the combined attacks of Lu Weiyin, Qi Sea Ancestor, and others, while never forgetting to strike at the Secure Earth Heavy Mountain Fortress.
The Secure Earth Heavy Mountain Fortress stood unshaken, immovable as a mountain!
Even a being like Spectral Soul found this deeply frustrating. His primary target had always been Fang Yuan and never changed. But to attack Fang Yuan now, he first had to breach this massive fortress. This enormous obstacle made even Spectral Soul's heart feel stifled with frustration.
If Spectral Soul ignored Fang Yuan and focused on the battlefield and these enemies instead, it would give Fang Yuan precious time to rest — something Spectral Soul was extremely reluctant to allow.
In the heat of battle, Spectral Soul turned his gaze toward Qing Chou, planning to use it as a breakthrough point once more.
