-(Not in the form of anime version, it's a new novel)
-World view: The energy channel between the human world and Ye Luoli's fairyland continues to be stable. The fairy power of the fairyland has experienced new fluctuations due to the development of human science and technology. Some saint-level fairies need to stabilize their power through "human society adaptation learning". Xin Ling and human universities have reached a "fairyland exchange student plan". The protagonist group and the fairy coexist as college students in the same institution-Ye Luoli City University.
- Core: The energy conflict between fairy power and technology, the secret war over resource allocation behind the exchange student plan, and the game between the selfishness of the protagonist group and the interests of the fairies. It no longer takes "protecting the world" as the absolute main line, but instead focuses on maximizing individual interests.
Purpose: Optimize the greatest good for each other's interests
