The cost of deducing a formula had always been low. Pei Ze consumed his elemental source without hesitation, completing the analysis in an instant.
A torrent of information instantly flooded the depths of his mind.
A moment later, after Pei Ze had digested all the information, he couldn't help but be taken aback.
'So expensive!'
Although he had long suspected that the metal combination to evolve a Tier Six Witchcraft Artifact would be incredibly valuable, the price tag of over seven hundred Magic Crystal Stones was still a shock.
And that was with one main ingredient excluded from the cost.
'The core of a level-four Thunder Elemental Giant Spirit... I didn't expect the Tier Six metal combination to include this.'
Pei Ze frowned slightly.
But on second thought, it wasn't so surprising. The core of a Thunder Elemental Creature could already advance his elementalization, so it made sense for Silver Star's evolution to incorporate a Thunder Element Core to be compatible with him.
