Fantasy: There Is a Tower of Babel in the Body

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.
