Yu Sheng lifted his head, and in the depths of the dense fog, he saw that thing crawling down along the glass curtain wall of the mall... or more accurately, "flowing" down.
It looked just like a huge blob of "ink" with a form. It covered the building, its surface rippling like an unstable liquid, constantly forming limb-like appendages from its edges, but each limb flailed meaninglessly in the air, disappearing in an instant, retracting back into that puddle of ink. It occasionally opened a maw-like structure, with sharp teeth and a tongue appearing inside. The maw sometimes emitted a low, murky muttering, but more often, it just gorged on the surrounding fog.
That liquid-like thing slithered down the mall's exterior wall slowly, looking utterly horrifying.
Little Red Riding Hood let out a gasp upon finally seeing it clearly: "'Ink Stain'?!'
Yu Sheng turned his head instantly: "What the hell? You know this monster?"
