Traveler of the World

I am the brightest firework walking in the world~ I don't know when it started, but there was a strange figure in my dream! No, it seems like two - one white and one black The two of them were fighting as if they were rivals. When they looked up, they saw that billions of stars were actually worlds. In those worlds there were beings that were so big that they could burst the multiverse in the blink of an eye, and there were also people that were as small as ants but could hold up a whole sky. They all disappeared under the remaining power of the two of them... This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
