Chapter 639: Lake Central Island

Just as everyone was somewhat puzzled, the four great Yin-Yang Realm Great Powers each took position in one of the four cardinal directions and cast a Dharma Seal towards the sky above Weak Water Lake.

Boom!

Lines of light arose around the edges of Weak Water Lake, followed by the slow emergence of an island at the heart of the large lake.

Everyone was momentarily stunned, all eyes fixed on the island that had appeared in the middle of Weak Water Lake.

"Didn't there used to be an island in the center of the lake before?"

"I understand now, this must be the Four Great Powers having discovered the island and directly laid this Formation to conceal it, which is why no one has found it until now."

"So that means, the Source Secret Realm is on this Lake Central Island?"

"It seems that way."

Many immediately understood; this explanation made sense.
