Underworld.

In a dark space of nothingness, Azrael sat, legs crossed and eyes closed, meditating.

The silence the space around him exuded was peaceful, like an untouched lake.

The space was empty, just like a void; there was no way to discern its beginning or end.

This was a skill he named Shadow Domain, a place that separated the user from the world into a void they controlled as they wished, escaping reality itself.

His purpose was to calculate the chaotic energy within him that could erupt at any moment.

After evolving his body to that of a demigod, his abilities became more powerful, and more energy could be contained within his vessel.

Furthermore, the Godslayer gene multiplied his strength. Now, he could rival a low-level god.

As time passed, the wild energy inside him that threatened to burst out slowly subsided with ease.

It now flowed like a beautiful blue sparkling stream, moving at a steady pace to every inch of his body.
