Histoire
I became a disciple of the strongest! Chaos began to invade the world. One day, a gate suddenly appeared in the world, and monsters poured out. Humanity stood on the brink of destruction. The world of martial arts, "Eun," the world of magic and knights, "Einheart," and the world of the demons, "Gehenna," were connected, and superhumans swept away the monsters. However, they were not righteous saviors. They persecuted the newly created "players" of Earth under the law of the strong. Lee Ro-Woon sought to bring peace to the world by coordinating the players with superhumans from other worlds.
