After Sixteen Years of Being a Cow and Horse, Now I Want to Be the Protagonist

When people travel through time, they always have harems and have a halo around them, but when I travel back through time, I just work as a cow, a horse, wash and cook? The past sixteen years of boiling water and chopping wood to feed livestock have been enough. Now, I want to be the protagonist. See, I am possessed by a spiritual boss, I am cultivating the emperor-level skills, I am just waiting for the five holy places, I am the top of all races, my magic weapon is nameless and I will not take it, and the miraculous elixir helps me cultivate immortality. Regardless of anything else, I want to get all the treatment that the protagonist should have, yes, all of it! This novel and its characters are purely fictitious.
