"Elf Core? What is that?" Upon hearing this, Leo Ray couldn't help but express his curiosity while looking at the green crystal floating above the withered tree not far away.
"My Lord, this is an extremely rare crystal that can only be made by the most exceptional elf magic artisans."
Jasper Richardson took off the Elf Core and returned to Leo Ray's side with light steps.
She handed over the crystal that emitted a green light, and then said, "I found it strange that even after thousands of years have passed, the powerful golem summoning technique should not have lasted for such a long time.
Without the supply of magical power, the tree guardian giants here should have disappeared long ago and could not continue to act and attack us. So, I thought about this possibility."
"Jasper, are you saying that the summoned tree guardian giants existed for thousands of years because of this Elf Core?"
