There are actually only four types of Gu.
The first type is called insect Gu, which includes birds and animals, snakes, insects, rats, and ants. In the final analysis, they all belong to the same category.
The second type is called dead Gu, which are dead things. Mountains, rivers, bamboos, rocks, plants, flowers and willows can also be used as Gu. These Gu are called Death Gu.
The third type is called witchcraft, which originated from the Twelve Ancestral Witches. To put it bluntly, it is the use of witchcraft to refine the body, making it invulnerable. Therefore, according to rumors, the ancient Twelve Ancestral Witches were physically powerful and unrivaled.
As for the fourth type, it is more evil and is called Beauty Gu.
The beauty is a poison, ecstasy destroys the soul!
