"Research purposes..."

"B-boss… what the fuck is that. That, is not fuckin' salt." Fumio points at Infinite Spiritual Energy Crystals that are slowly turning blue, and feeling the spiritual energy condensed inside of it.

"It's not." Red exhales deeply, seeing the seal formation stabilizing itself just as he expected.

"Man…" He shakes his head, still in awe.

He still cannot believe that Terra has billions of tons more of these crystals in its reserve, and that reserve is located in just one country. He hopes that there are more undiscovered reserves of it.

"One piece this size..." He picks out a watermelon-sized piece from the pile of the crystals.

"…when filled to its limit, it's going to be an even better spiritual energy source than demon cores." He explains to Fumio.

"Well… Demon cores have a lot of classes." Fumio wants a more specific comparison.

"Even better than a core from high-tier Knight-ranked demon. Six cores' worth in fact." Red reveals.
