Chapter 288 Deep Erosion, The Other Side of the Jiuyou Channel_2

Surrounding the square was a massive fortress made of metal.

As an Artifact Refiner, Lu Yi had a discerning eye and he immediately realized that these were all made of Immortal Gold.

He was a bit surprised in his heart, could it be that this enormous fortress was entirely constructed from Immortal Gold?

Even if it wasn't a Planet Fortress, the difference wasn't that much.

Weird Array Patterns were engraved throughout the fortress.

These Array Patterns were something Lu Yi had never seen before, which made him somewhat astonished.

Seeing this, Ling Luo Peak Master explained, "These are Array Patterns designed to disperse the Jiuyou Qi. Generally speaking, Cultivators who have been corrupted by Jiuyou will struggle to conceal their true forms within such a Great Array, though there are exceptions. Therefore, at the exit, there are specially crafted cultivation treasures dedicated to detecting whether a Cultivator has been corrupted by the Jiuyou Qi."
