Prompt: In appearance, the fall of a small, pea-sized black hole on thousands of undead troops is a scene full of catastrophic destructive force and apocalyptic atmosphere.At first, when a small but very dense and heavy black hole approaches the earth, its appearance can be seen as a small dark spot in the sky, which rapidly increases in size. Cosmic vortices and energy eruptions begin to form around the hole, creating an ominous appearance of the resulting phenomenon. As the black hole approaches the earth's surface, powerful gravitational waves begin to tear apart the earth and form huge cracks and splits in the earth's crust. The earth begins to shake, and powerful shock waves spread throughout the area, causing the destruction of buildings, trees and everything in the path of the falling hole, The most terrifying part of the scene begins when the black hole reaches the earth's surface. The undead, creatures already devoid of life, turn their attention to the horror approaching them through the gates of hell.
