Capítulo 400: Surprised Oliver

Grey didn't find Klaus' father's decision to leave the empire surprising, after all, they couldn't go against the empire. 

"Wait, you found drops of liquid of the Great Earth Essence Liquid?" Oliver seemed to recall something and asked. 

This was something that could alter the constitution of an Elementalist, changing their elemental grades. It was so rare that not many people believed it existed. 

"Yes, back at the trial land," Grey replied. 

'No wonder they've been advancing so quickly. With that thing, their elemental grades must've seen a boost. Could it be that they've attained the violet grade?' Oliver thought to himself, surprised. 

He never thought that they would acquire something so precious in the trail land. Now he understood why the Emperor was searching for them so fervently, given the miraculousness of the Great Earth Essence Liquid, these youngsters go easily grow to overpower the people at the top.
