Deep Water Fish Monster

It rained abnormally for seven days in a row, and the city was enveloped in gray vapor, with a faint fishy odor permeating the rain curtain. Standing in front of the apartment window, Tang Wan always felt that there were invisible things crawling in the corners flooded by rain - sewer mouths, abandoned rivers, and pools in underground garages. It wasn't until the first mutilated corpse floated out of the river, and the deformed fins scratched the water, that panic really spread. The rain is still rising, and there are more and more mutated fish. The small ones are like palms with sharp teeth, and the big ones can break the glass of the shops facing the street. Main roads were blocked, water and electricity were cut off, and the city was completely paralyzed.
