It doesn't remain still like an ordinary mist; instead, it seems to be gently breathing.
At times, it subtly undulates, resembling a massive heart beating rhythmically.
It flows in a unique and eerie manner, giving a sense of dangerous mystery.
Suddenly, the previously calm flowing blood mist starts to surge fiercely.
The thick blood mist rolls violently, like ocean waves swept up by a fierce gale, emitting a low, howling wind sound.
Immediately, the blood mist swiftly converges towards the center of the area, as fast as a thousand galloping steeds.
It seems like a gigantic Abyssal mouth opens in the darkness, mercilessly engulfing all the surrounding blood mist.
During the convergence, the blood mist continuously twists and distorts, forming a gigantic vortex that gathers towards the center.
As time passes, the blood mist gradually thins out and eventually completely dissipates.
At the center of the area, a blood cocoon taller than a person appears.
