After slaying the Black Dragon's remnant soul, Wu Shaochen immediately flew to the stone pillar to collect the source crystal. This thing couldn't be left behind.

He then retrieved the other two energy crystals.

What Wu Shaochen didn't expect was that in such a short time, the energy in the two energy stones had already been depleted.

Wu Shaochen shook his head, not too concerned, since these things could be recharged. He casually placed the energy stones into the Heaven and Earth Ring, then collected the four energy stones that were already depleted, maximizing his gains.
