What is the difference between "demon" and "ghost", "demon" and "essence"? Have they evolved?

None of these things exist, but their meaning can be explained in other ways.

"Ghost" is the soul after death. From a scientific point of view, "ghost" is not real and is formed by people's imagination, but I am superstitious, so I think it exists.

"Magic" is not a real concrete life or creature. (The "magic" itself does not exist, but its appearance is created by someone or something whose heart is distorted)

Its appearance: it can generally be described as a shemale (the human heart is distorted because of XXX), thus changing the essence of that person and replacing his original behavior and thoughts or other creatures distorted by various factors.

"Demon" is not a real concrete life or creature. The legendary "demon" is generally an animal or plant that has been cultivated to become a demon. It can also be said that it is a mutated devil, appearing in a single form. )

"Jing" is not a real concrete life or creature. ("Beijing" has become Beijing, what else is there to say? Generally speaking, essence refers to elves. They are neither demons nor demons, but they are not human. However, they are called close to humans in appearance. It should be said that the body is formed in the mold of human beings, and the appearance sometimes combines the characteristics of demons and approaches the essence of angels or immortals. Generally appear in group life. As long as there is one elf, there will be another or more.
