Adjusting the intelligence of a creature, in ancient Chinese myths, was called a ''Fairy's Touch,'' awakening Spiritual Intelligence.
If explained from a biological perspective, it means that a creature's brain capacity increased, the sulcus and gyri of the brain deepened, and the surface area of the cerebral cortex expanded, thus allowing the creature to have sufficient intelligence to think and become self-aware.
In the Multiverse, there is a basic criterion for classifying intelligent beings: self-awareness. Only those creatures that can recognize their existence and are aware of themselves are acknowledged as intelligent beings by the Multiverse.
Although ordinary wild beasts can sometimes display signs of self-awareness, like recognizing themselves in a mirror, they don't truly develop self-consciousness or a clear awareness of their own existence.
