At this moment, He-Gu felt dizzy, as if his ears were submerged in water, filled with a constant "buzzing" sound.

In his hazy vision, He-Gu saw the sky covered with dark clouds, as if the entire world had plunged into darkness. The clouds hung low, and faint flashes of lightning could be seen.

Every time lightning flashed between the clouds, it illuminated dense patterns for a brief moment.

He-Gu strained to see and discovered that these dense patterns seemed to be composed of obscure runes.
