The power of the Formation at Medicine Valley was far greater than that of the Great Reversal Valley on the Cloud River battlefield.
For one, Lu Ye's proficiency in the Array Path had improved immensely since then, and furthermore, Medicine Valley had an Earth Vein, enhancing the formations he set up within the valley by aligning with the Earth Vein's trends, adding to the Formation's might.
There was no such convenience at Great Reversal Valley.
Under Wu Xie's lead, many Sky Ravine Sect cultivators plunged into Medicine Valley and vanished, leaving only the massive, churning fog sea in sight, which was unpredictable and ever-changing.
Anyone could sense the chilling killing intent from the fog sea.
"A formation," Yun Haitian's expression changed dramatically, not expecting such an astonishing big array to exist in Medicine Valley.
