"Fellow Daoist Shen, you seem to know the origins of the tomb above?" the Bull Demon King asked, looking over at him.
"I once spent some time near Chang'an City, so I know a little about this place. These are the Yin Ridge Mountains. The tomb above was supposedly built by a prince of the dynasty preceding the Great Tang. For some unknown reason, large numbers of ghosts appeared here," Shen Luo explained briefly.
"I see. But what are these jade pillars? Why is there such dense yin energy inside them?" the Bull Demon King asked curiously, looking at a nearby pillar.
"These are no ordinary stone pillars. Astral seals are engraved on them, imprisoning vast numbers of souls. Nor were the pillars placed at random. They appear to follow the layout of the Stellar Heavenly Cycle Formation, a wondrous formation from ancient times," Zhen Yuanzi said after surveying the pillars before him.
"The Stellar Heavenly Cycle Formation!" Shen Luo exclaimed in surprise.
He had read about this formation in ancient texts. It was one of the ten greatest ancient magic formations, and supposedly ranked very high among them. It could draw down the astral power of the heavens to destroy its enemies, sharing quite a few similarities with his Three-Star Demonbane Divine Ability.
The Bull Demon King's eyes also lit up. The Stellar Heavenly Cycle Formation was a wondrous formation of the ancient Demon Race, but sadly, it had long since been lost. He had never expected to find it here.
"Moreover, the souls inside these jade pillars do not appear to belong to ordinary people. They seem to be the military souls of soldiers with steadfast wills," Zhen Yuanzi continued.
"Soldiers' souls?" Shen Luo paused in surprise, then looked at a nearby jade pillar and flicked a finger.
