In an instant, thunder and lightning flashed outside, and the dark clouds pressed on top.

The next day, a strong smell of blood filled the surroundings. The cleaner who cleaned up the garbage hurriedly called the police after smelling it. In the room, the police found 6 corpses that had been gnawed incompletely and a mental patient.

In the afternoon, a scavenger in shabby clothes came to report and said that yesterday, by lightning, he saw in that room, countless black shadows stuck to those people, and countless blacks on the roof. Shadow hovered and swooped down from time to time, biting those people. Later, the scavenger was sent for psychological counseling, and the mental patient was sent to a mental hospital, hoping that one day he would recover and be able to find out.

However, a few months later, the man disappeared out of thin air, leaving only one piece of clothing. The police had no clues, and the case was gone.
