"There should be some limit to how many creatures those glowing sacs can produce, right? Whatever is fueling it, it shouldn't be limitless. But, strangely, the sacs show no sign of slowing down its production despite the demons' efforts."
While observing the intense battle between demons and tree-like creatures inside the second trial, Darlene brought the matter to Aria's attention after noticing the detail.
However, she was not the only one to have noticed the problem. Aria and the others also found it strange at a glance.
"Mm, it is strange." Aria nodded before saying, "However, a Demon King's means is not something people at our level can understand."
"Though, if I had to make a wild guess, I would say that there's a chance that the power source fueling the sacs is capable of replenishing energy at the same rate as its expenditure. In that case, it might as well be limitless."
