"Demon World" is a martial arts fantasy novel. The main plot of the novel is the practice of "Shentian Scroll". The background of the story is: the founding god disappeared into the vast universe after the creation of the world. No one knows where he came from and where he went. After the founding god disappeared, he was left with a race of gods whose talents were close to those of gods, a race of humans who lived widely on the earth, and a race of demons who often appeared in various identities and existed in the world. The three tribes fought with each other and kept coming and going. Later, the Gods suddenly discovered that because the three tribes wanted to destroy the other two tribes and continued to increase their power, the world was actually on the verge of a very dangerous situation. Because once the increasing power reaches a certain level, it will be uncontrollable and destroy the entire world. The gods told this secret to the humans and demons, but it was regarded as a conspiracy by the gods. The Gods had no choice but to use their talent to be close to gods to work hard to enhance their own power so that they could control the other two races before the catastrophe and avoid the catastrophe. But soon, the Gods discovered a more terrifying situation: the existence of the world now actually depends on the relative balance of power among the three races. Once this balance is broken, the world will also fall into a catastrophe of destruction. Maintaining the status quo will inevitably lead to catastrophe. Trying to develop yourself will lead to catastrophe faster. The Gods were in an extremely difficult situation. Just when the gods hesitated, the catastrophe inevitably came.
