A Chinese Cultivation of Immortality

About 1,500 years ago, due to a natural cataclysm that occurred near the solar system, a space-time black hole leading to another world suddenly appeared above our human world. As a result, various monsters living in other worlds also came to the world from this cave. Since then, our world has been ruled by all kinds of demons. It seems that we, the tiny humans, have completely become the food of the demons. In addition to facing attacks and devouring by the demons every day, we also engage in life-and-death battles with the demons. Therefore, organizations to deal with these demons have also been established around the world. This is a world where humans and vampires of light and darkness coexist. In a sense it's darkness and light. The battle between the vampires of darkness and light begins in the human world. This novel and its characters are purely fictitious.
