For two days, Liam spent his time cultivating his essence cultivation, the amount of essence in his demon core have increased.
He opened his eyes after some time when he discovered that the amount of energy that he absorbed have started decreasing till the point when ordinary essence was observed.
He moved his eye to the primeval stones, there wasn't any essence in it.
"The first primeval stone was low grade and it lasted for two years, the other was the same and lasted for about a year and two months but this one only lasted for eight months at most, now I only have one left, how should I get more of it? the primeval essence in the primeval stones are better than the ordinary world essence the lingers in the air because of my demon core."
Liam gazed at the primeval stone that has no energy in it anymore, he sighed and looked ahead to see his two hostage gazing at him with strange looks in their eyes which has redden.
