A Game That Invades a Fantasy World

A small group of wealthy people on Earth discovered a different world. They built a highly realistic game that simulates a different world. They recruit various game elites from all over the world to participate in the so-called closed beta test and provide them with strategies for invading other worlds. By a strange combination of circumstances, a very ordinary student was tricked into a bizarre game. Unite people from other worlds, eliminate careerists, and successfully prevent the invasion of other worlds.
