The Beast King's Path to Immortality

The Protagonist Isn't Human, Never Takes Human Form, No Romance, No Ambiguous Relationships

The protagonist shouldn't be human, there should be no romance or love interest, and they shouldn't take human form or meddle in other people's business. They should be decisive, like *Evolution Begins with a Big Tree*.

Do You Have Any Recommendations for a Book from Animals to Demon Cultivators?

I have read a book called Deer Demon Chasing Deer. Modern people travel to a deer and slowly start to practice. From the animal world to the world of cultivation, it is very interesting, very real and immersive. But I only found out about the book Eunuch after reading more than a hundred chapters. Please recommend similar books.
