Chapter 766: World Core (Part 2)

"Damn it, it's not enough," Evan said as he emerged from the Essence Formation Room. It had been one month since he started cultivating in the Essence Formation Room. The aura surrounding him was slightly stronger than it was a month ago, but he was still far from reaching mid-level Rank One.

"I thought I would reach mid-level Rank One in one month, but I'm still at the 68% mark and need to fill the remaining 32% before I can advance," Evan muttered and sighed after leaving the room.

Initially, Evan's core progressed smoothly. But once his core crossed the 50% mark of the Beginner Level Rank One, its progress slowed down considerably. After reaching the fifty percent mark, the energy that his core required for further advancement nearly tripled.

This sudden increase in required energy slowed down his core's progress, even though he was cultivating in the Essence Formation Room.
