National Mobilization of Clones

If there is another world! What? Not rare? So boy, is there a clone of you in this world? That's right! This is an era when any ordinary person can enjoy two lives, one with food, rice, oil and salt, the so-called ordinary, and the other with the sword and sword, the so-called adventure. The living space of zero-dimensional creatures is an origin, and their life forms the X-axis. The life space of one-dimensional creatures is the X-axis, and their life forms the Y-axis. The living space of two-dimensional creatures is a plane, and their life forms the Z-axis of space. As three-dimensional creatures, human beings live in a three-axis space, and their lives form a timeline, which is the fourth axis. This is the story of human beings stepping into the world of clones, breaking through the limits of dimensional thinking, obtaining the fifth axis, and ascending the dimension as a whole!
