Prompt: On a profound night, the moon hung in the pitch-black sky, casting its glow upon an ancient mysterious temple. At the base of the temple's mound, a colossal millstone stood tall, drenched in a dark red liquid, resembling the flow of blood. At the entrance of the temple, a venerable Taoist held a ceremonial instrument, his countenance solemn and his gaze deep. Bathed in moonlight, a terrifying monster emerged stealthily from the temple's shadows, its black wings enveloping the entire scene, and its peculiar feathers shimmering in the moonlight. The villagers in front of the temple gripped torches, watching this spectacle with a mixture of tension and fear.
