A group of people stared blankly at the Taiji diagram hovering in midair, their faces filled with astonishment.
Particularly, Elder Huang and Mountain and River Elder nearly popped their eyes out, staring incredulously at the Taiji diagram and then at Yang Zhen, too shocked to speak.
After a moment, Elder Huang's face turned red as he sharply inhaled and exclaimed, "Heavenly Secrets Reversal Array, impossible, that's a formation from the Barbaric Era, how could you possibly master it, no, this formation has long been lost."
Mountain and River Elder also wore a look of disbelief, muttering to himself, "Heavenly Secrets Reversal Array, such a defy-the-heavens formation, how could it possibly appear here?"
The Heavenly Secrets Reversal Array, a legendary formation said to reverse the power of Heaven and Earth, was a powerful formation from the Barbaric Era.
This kind of formation had completely vanished, and even many practitioners from the Cultivation Era had never heard of it.
