Transmigrating Across Myriad Worlds in the City

This book will show you the wonders of the myriad worlds.

Can a blade of grass cleave the sun and moon?

Can a grain of sand fill an endless ocean?

Well, basically, the protagonist shows off in all kinds of worlds. There's no harem, so if that's what you're looking for, don't bother. The author is a novice, too, so if you only like beautifully written prose, don't bother either.

This novel and its characters are entirely fictional. Any similarities are purely coincidental. Do not imitate.
