One hand was placed one each of their heads, as sudden headache hit started for both of them, and they felt like someone was trying to crush their skulls open.
It wasn't the first time that they experienced such a pain, but it was the first time it was in this intensity.
Furthermore, this time it didn't look like their Master was looking only to pry inside their heads, but like he was about to devour their souls.
In fact, it wasn't like but the harsh reality. The First Prince truly had that intention in his mind, he was trying to devour their souls.
Well, it looked cool and easy when one talked about it, but the truth was that his method wasn't really effective.
As a matter of fact, the First Prince could only absorb about 10-20% of his targets Soul and Soul Power. To someone on his level that amount was just like a shot of water in a hot summer.
