Shen Yi had finally waited for his chance. With speed too swift to cover one's ears, he unleashed his inner world and absorbed all of Qian Duo's magical treasures into it.
He then activated the Four Spirits Great Array. In an instant, everything within several hundred miles was shrouded by the grand formation. Within the Supreme Hall's territory, four terrifying auras suddenly rose up, pillars of light shooting into the clouds and forming four different phantoms in the void.
"Azure Dragon, Vermilion Bird, Black Tortoise, White Tiger!"
Through the Mystic Light Mirror, the onlookers also saw the four sacred beasts slowly descending through the void. They all sucked in a breath of cold air. This formation could actually summon the legendary Four Sacred Beasts—there was no need to think twice about how formidable its power was.
Among them, Qian Duo and Ling Feixing bore the brunt of it. Standing within the formation, they felt waves of terrifying majesty pressing toward them. Even with Spirit Transformation cultivation, they found it somewhat difficult to endure.
"What formation is this? It has actually hindered both of our movements!"
Qian Duo was somewhat flustered. Every profession had its specialty. Though he possessed countless magical treasures, he knew very little about formations. Ling Feixing beside him happened to be a Spirit Transformation expert with profound attainments in formations. Tianyi Immortal Academy had sent him here this time precisely in the hope that he could help Qian Duo break the Supreme Hall's mountain-protecting formation. Who could have expected Shen Yi to have another trick up his sleeve?
"Formations capable of completely suppressing cultivators are rare in this world. In my opinion, this is the Four Spirits Great Array, which was said to have been lost long ago!"
A trace of gravity flashed through Ling Feixing's eyes.
