The mountain range formed from Ten Thousand Weight Stone possessed an immensely powerful gravitational field, as though it were made of material from a white dwarf star.
An ordinary martial artist's true essence and divine sense would find it difficult to penetrate the interior of a Ten Thousand Weight Stone mountain range.
Even a seventh-tier expert could not do it.
But Gu Yi was different. He wielded the Power of Space, and after attaching it to his divine sense, he could barely force his way inside.
Gu Yi gathered his divine sense and painstakingly entered the interior of the mountain formed from Ten Thousand Weight Stone. To his surprise, he found countless densely packed lines within.
They spread throughout the mountain range like a spiderweb, filling every corner and forming a mysterious, profound spirit formation diagram!
However, several dozen energy threads had been severed by some force, preventing their energy from flowing.
Gu Yi's attainments in formations were not particularly high, barely reaching the Fifth-Tier Peak.
Thus, he could not see through the mysteries of this spirit formation diagram, which was at least seventh-tier, nor could he replicate it.
But merely repairing several dozen broken energy patterns was still not difficult for him.
