Chương 558: Devour Legendary Energy Core 3

The tunnel led down to the underground 12 kilometers away from the bottom of the ground.

Here, Wu Wei sensed an extremely weak spiritual power.

At the same time, he saw the gray rock layer. Wu Wei knew that this was the Spirit Concealing Layer. It was the outer layer of the spirit stone mine that prevented the leakage of spirit energy. Wu Wei asked the three little cuties to search along the Spirit Concealing Layer.

Soon, Wu Wei found a crack in the Spirit Concealing Layer.

After finding this one, Wu Wei immediately chased away the three little cuties who were looking forward to eating.

Well, Wu Wei's behavior was really despicable.

After sending the little cuties away, Wu Wei started to get busy.

Wu Wei first used the Maze Formation to cover up the leakage of spiritual power, then he expanded the gap in the Spirit Concealing Layer.
