Chaos, the number one villain, is an image that does not exist in the original work. In most of the film, "Chaos" appears as a cold-faced scholar, and finally a six-legged giant with fangs.
The word "chaos" originally refers to the primitive state of the universe before the division of time and space in the ancient creation legends of China. The creation process of the universe is described as: Taiyi → Shu Tai → Shu Tai → Tai Su → Chaos → Heaven and Earth → Everything. "It's too easy, out of breath. The beginning is the beginning of qi. It's too early. It's similar in shape. Tai Su is the beginning of quality. Qi, such as quality, is called chaos. " In other words, chaos refers to the state that qi, shape and quality are integrated and have not been separated. The story of "Zhuangzi's Inner Chapter, Emperor VII" is a story of "seven out of chaos and death". Our emperor is Shu, the emperor of Beihai is Hu, and the central emperor calls it chaos. When san huang met each other, he suddenly reported the favor of chaos. Seeing that everyone has five senses, chaos has no seven, so he chiseled seven for it. The sun chisels one thing, seven things come out, and they die in chaos. The description of chaos in Hanshu Lingyi Jing Xiye Jing is: "There are animals in the west of Kunlun, like dogs, with long hair and four feet, like no claws, no eyes, no movement, no ears, some people are intelligent, there are no five hidden things in the belly, the intestines are straight but not spinning, and the esophagus is open." People have virtue and resist it, while virtue relies on it. "The chaotic elephant here is similar to a dog, with long hair, four feet, no claws, out of sight, out of ear, walking without steps, no internal organs in the rectum, and it is difficult to distinguish between good and bad.
In the above legend, although "chaos" has the difference of insect shape (six feet and four wings are the characteristics of insects), dragon shape (seafood should be dragon) and dog shape, the similarity of * * * is the differentiation of five senses, like a piece of meat. The demon king in The Return of the Great Sage adopts the shape of a faceless sword blade, which accords with the description of chaos in ancient books.
