I Evolve the World Inside My Body

The Protagonist Manages a Plane and Constantly Upgrades the Plane.

And then continue to incorporate other dimensions into it

There Is Portable Space, World Tree

Pasture

Open up the World Inside the Body, from the Small World, the Big World, the Small World to Nothingness

I want to read a book similar to "I, the Way of Heaven, Build the Strongest World". The world opened up inside the protagonist's body needs to be systematically written, with a large world view, from the small world to nothingness, unfinished, and serialized.

The Protagonist Opens up the Inner World, Masters the Three Thousand Avenues, and Perfects the Inner World.

It is best to be a fellow Xianwu practitioner

Dantian Opens up Space and Evolves into the Original Universe

Space evolves into the primitive universe

Creation, Heavens, Small World, Space, Evolution,

The Protagonist Creates a World and Then Puts the Players into It to Create Their Own

It would be best if there is no heroine, similar to "I Created the World".

Looking for a Novel Where the Protagonist Has a Small World or Creates a Small World
