Bai Yan wanted to destroy the world, but it was only a momentary thought. But, how could a system calling itself fox bind him? And he said that his wish could come true? Well, there's nothing to miss in this world anyway, so there's no harm in going on a mission. But why is the mission to go to a parallel universe to save the world? How can personal annihilation be the destruction of the world? Well, everyone is their own protagonist. If the protagonist disappears, the world that belongs to that person will be destroyed. However, this system seems not simple. Also, who is that familiar person who appears every time he goes on a mission? "Crane"... Where have you heard it? Bai Yan thought for a while: Forget it, let me see what you want to do.
Concept: The world is dark, but there are always people who are the light
