Accurately speaking, there is no clear ending. The author sets two endings for readers to see which one readers are willing to recognize. Why do you say that? Because in the whole story, Ning He, the protagonist, encountered many strange things that could not be explained by common sense, such as his wife Dong Xinjie appearing outside the door several times in a row, the dark-haired monster who suddenly appeared and disappeared, and Faye Wong who seemed to have supernatural power. As I said just now, the author has set two endings to see how readers choose. The first result is that Ning He had an accident in mountaineering activities three years ago and became a vegetable. But Ning He's brain is not dead. By instinct, Ning He's brain began to construct a virtual world. All the horrible and bizarre events he encountered were made up by himself, and everything was false. When Ning He was lost in his imaginary world, his wife Dong Xinjie invited psychologist Faye Wong to treat him. Wang Fei knows that the human brain has a defense mechanism to protect itself, so psychologist Wang Fei must find a way to activate the defense system of Ning He's brain. So Faye Wong adopted various psychological suggestion methods, invaded the virtual world in Ning He, and created many unexplained strange events in the virtual world in Ning He, which made Ning He, who was in the virtual world but didn't know it, doubt his own world. At the same time, Ning He's own consciousness must maintain his own virtual world, so whenever Ning He finds many unexplained events (that is, the hints implanted by Dr. Faye Wong in the real world), in order not to let Ning He wake up, the idea of maintaining his own virtual world constantly tries to find ways to automatically repair these contradictions, which leads readers to see more and more problems. Two forces in Ning He's brain have been at war. One is the virtual world constructed by Ning He, and the other is the brain defense mechanism manipulated by Faye Wong, which causes Ning He to encounter strange things constantly. The virtual world tries to maintain its own balance and rationality, and the defense mechanism constantly creates unreasonable events to make Ning He doubt the world.
