Virtual reality technology has developed rapidly in the past few years, but it is still a challenge to create a completely virtual online game like the novel. The current level of development of virtual reality technology was not enough to realize a completely virtual world. More research and development and technological breakthroughs were needed. Virtual reality technology could allow users to experience the immersive feeling through head-mounted displays, controllers, and other interaction devices. However, virtual reality technology still had some limitations, such as the high price of virtual reality equipment, long-term use would cause damage to the eyes, and the realism of the virtual reality world needed to be further improved. In order to solve these problems, game developers needed to create a more realistic and rich virtual world and provide more interaction methods such as gestures, voice, and body sensations. In addition, more efficient virtual reality technology was needed to provide a better experience. Although virtual reality technology was constantly developing, a completely virtual online game like a novel was still a challenge. It required more technological breakthroughs and continuous innovation to achieve.
