Space and time began as a mass of black chaos. Before that chaos was opened, neither space nor time existed, much less the myriad things of heaven and earth.
It was through Kamui's power that Deva Path had carved a world out of the chaos.
Thus, chaos matter was the "raw stock" needed to create space and time. In recognition of Kamui's contribution, Deva Path had granted Kamui the power to produce chaos matter!
Now, Kamui had passed that power on to Yu, giving him the ability to create space and time!
Whoosh!
Black chaos matter appeared in the palm of the Human Yama Dharma Body, taking the form of a sphere.
Kamui said, "The strength of a space-time depends on the density of the chaos matter that gave birth to it. The same amount of chaos matter will produce different strengths if the space-times created from it differ in size."
Yu said, "That's middle-school physics. I get it. In other words, I should make the space as small as possible and pack more chaos matter into it to increase the density..."
Kamui said, "Hmph. Chaos matter has a maximum density, too. My original Space-Time Dimension represents that density threshold. Deva Path created it before splitting apart. Even as the One True God, you can't achieve that density. Still, with your current power, getting infinitely close to that threshold should be just about manageable. I've already calculated everything for you. Expand the chaos matter to 'that size.' That size, yes, exactly that size..."
Whoosh!
Following Kamui's calculations, Yu expanded the chaos matter amid the stars. The original space-time remained completely unaffected. The expanded chaos matter would form an independent space-time of its own; its spatial coordinates would simply lie near the point where it had been expanded in the original
