Yaoguai(妖怪):

Yaoguai is a compound word, the full term being a combination of “Yao” and “Guai.” These creatures often possess unusual appearances and mysterious abilities, typically regarded as existences somewhere between humans and Immortals. The images and stories of yaoguai are extensively represented in folklore, literary works, and modern visual media.

Mythical yaoguai are formed from plants, animals, and even non-living things that have failed in their cultivation to become Immortals. Additionally, they can include humans and animals who failed in their attempts to become celestial beings. Broadly speaking, yaoguai refers to all objects possessing superpowers or Magic spells that are neither Immortal nor celestial beings nor humans.
