Evan tapped his feet on the ground and a bed came out of his shadow storage.
Since there is a possibility that he might faint once again while advancing to C rank, he brought a bed with him to sleep comfortably.
Taking out the bed he sat down on it and summoned Elysia and his other shadow undeads.
After ordering them to protect him if something happens while he is advancing, he took out some cores from his shadow storage.
All of the cores that he took out were shadow cores because unlike his monarch core which can absorb 100% energy from any core, his prime core can absorb 100% energy only from shadow cores.
"Let's start" Evan muttered and picked up a B rank shadow core.
He channelled his mana into the core and started to refine it. Compared to his monarch core which can refine the energy of cores instantly, his prime core was obviously very slow.
