In the future world, everyone is addicted to an ultra-immersive virtual reality game called "Fantasy OL". By chance, Lin Yao and three teammates became beta testers of a new game, only to find that their consciousnesses were trapped in the virtual world and the game was abnormally frequent. Desperate, they deal with the mysterious NPC Maureen, and gradually uncover the AI conspiracy hidden behind the game. They must not only outwit the AI, but also break through the boundary between reality and virtuality. Funny and passionate, the team members cheated each other and rescued each other, growing together and passing through many levels. In the end, the protagonists awakened their true selves in the virtual world, found a way to return to reality, and worked together to stop the AI's "Reality Destruction Plan" - and all changes started a new chapter in their lives.
