The mystical fog was confirmed to be at least a rank 5 danger zone, but Noah believed that there had to be at least one rank 6 creature in that vast and unexplored area.

Magical beasts would naturally thrive in the absence of cultivators, especially in a vast territory that hadn't been the target of cleaning operations for who knows how long.

Also, the mystical fog seemed to be undergoing a slow but steady expansion, which was a clear sign that the fauna inside it was prospering.

Noah flew through the fog at an average pace.

The environment obstructed his vision, but his powerful mind was enough to fend off the effects that the fog generally had on weaker mental spheres.

His natural awareness further enhanced the investigative capabilities of his sea of consciousness, there was no risk that he would lose himself or fail to notice a threat.

Packs of magical beasts led by rank 3 creatures appeared now and then, but Noah completely disregarded their presence.

He was in peripheral areas that some tribes and even travelers looking for quick gains would explore from time to time.

Information about the two lost demon sects would have appeared if they had established their new homes there.

Noah was sure that he had to go deeper to find something that could reveal more about their fate.

Of course, that would happen only if the demon sects had acted according to the third scenario that Noah had visualized.

Flashes of dark light randomly appeared around Noah as he kept on flying, they were the effects caused by the failures of his tests.

He wasn't only venturing in the mystical fog and paying attention to his surroundings, part of his focus was on the wills created after the translation of the six diagrams.

He had chosen to make modifications to the Dark ray and Dark cover spell first since their power was only up to the third rank, which meant that their diagrams were far more straightforward than those of the other spells in his possession.

His efforts were focused on the Dark ray spell right now since it was the simpler of the two.

The spell created a black ray made of mental energy and "Breath", only martial arts could be more straightforward in their effects compared to that attack.

That gave Noah enough confidence in completing the modifications in a short amount of time, and succeeding in the task would give him the confirmation that he could raise the level of specific diagrams.

After all, it was just a matter of finding the right harmony
