Chapter 856: Shocking the Dark Faes

"Anyway, are you sure this crystallized soul core still has plenty of soul energy?" Leon suddenly asked. 

"Why do you ask?" Duna furrowed brows in response. 

She did not understand why he needed to ask such a question. 

"Because this crystallized soul core was imbedded in the Teleportation Array and acted as the catalyst for the collection of souls to fuel the secret realm's opening," Leon mentioned.

"So I'm guessing it doesn't have much soul energy anymore."

"And here I thought you were being generous, but it turns out you thought the soul energy had been exhausted," Duna smiled mockingly.

"If the soul energy in this crystallized soul core were exhausted, it would lose its ability to attract other soul energy and recharge itself; a certain level of soul energy is needed to maintain its ability."

"I see…" Leon uttered with understanding.
