A large pile of ash lay on the ground. It was still giving off heat when Gao Peng walked up to it.
As he rummaged through the ash pile for a while, Gao Peng's hand grazed against something solid that he quickly pulled out.
It was the Golden Palm Tree Spirit's core crystal, which was as big as a goose's egg. It was also gleaming with a bright green light.
Monster core crystals contained extremely high element concentrations. These elements usually rejected one another.
As a result, these crystals were impervious to elemental attacks. The only thing capable of breaking them was physical attacks.
The core crystal in Gao Peng's hand belonged to a plant-type Commander-tier monster. Its market value was at least a few thousand Alliance credits.
Only those who were truly strapped for cash would sell one. Ordinarily, Monster Trainers would trade these crystals for something else.
