In an instant, everyone seemed to be on a bloody battlefield, or witnessing an ancient god and demon ritual, with countless creatures praying in despair and agony.

The Left Vanguard, who always prided himself on his bravery, was now pale-faced, cold sweat on his forehead, nervously looking around.
The wall was covered with blood vessels like tree roots, now completely black, decayed into a tar-like substance.
