True Man Tiange and the gray-robed middle-aged man behind him suddenly moved. In the next moment, they each stood atop the remaining two cyan stone pillars.
True Man Tiange formed a hand seal with one hand and chanted several obscure incantations. With a flick of his hand, he emitted a ray of cyan light.
At the same time, the other three Grand Elders performed the same actions, and four cyan spells simultaneously landed on the ground formation.
The surface of the huge formation on the ground suddenly emitted a humming sound. The runes on the four cyan stone pillars gradually brightened. The light flowed like water, slowly infusing from the cyan stone pillars into the formation on the ground.
For a moment, a vast expanse of cyan and green light surged wildly from the center of the formation, spreading all over the surface of the formation, and instantly formed four concentric circles of light within the formation.
