In this world lies a valley known as the Dark Night Valley, the darkest and most gloomy place between heaven and earth. At every moment, a massive number of vengeful spirits breed here, densely entangled together, forming powerful vengeful spirits like venomous insects in a jar.

there stands an unpretentious, natural stone cave.
