647 The Boundary Between Mountain Sea Realm

If only for the sake of obtaining pure Heaven and Earth energy, Chen Fei could completely crush the elemental stones, obtaining normal energy to place into the first spatial grid.

Then, he could use the second spatial grid to absorb the Energy here, contrasting the two grids, allowing impurities to remain in the second grid while the Energy transitioned to the other first grid.

The rule of the spatial grid is to only retain one thing, with one grid retaining impurities and the other retaining normal Energy, which is flawless.

With this in mind, Chen Fei's gaze flickered slightly. It seemed that most of the major Energy issues had been solved in an instant, while the remaining part was how to store the Energy here into the spatial grid.

The Energy here, summarized with impurities, seemed somewhat vague.

In Chen Fei's perception, this Energy seemed to have its own will inside. Or rather, there were other people or eerie wills within it.
