Even if it's just a low-grade Flame Crystal Stone, one low-grade Flame Crystal Stone can be exchanged for ten thousand low-grade Spirit Crystals, and the energy contained in ten thousand low-grade Spirit Crystals far exceeds that of a single low-grade Flame Crystal Stone.
Therefore, if Lin Chen were to hand over all these Flame Crystal Stones to the Primordial Myriad Transformation Cauldron for absorption now, he would be at a great loss. After all, these Flame Crystal Stones could be exchanged for countless low-grade Spirit Crystals if taken outside.
But calculating the time, Lin Chen could enter that mysterious world again for body refinement. However, if he didn't spend some Spirit Stones to illuminate the eleventh Star Map, Lin Chen would only be able to cultivate for fifty breaths in that mysterious world, which wouldn't allow him to train long enough.
