"That Tang Monk has cultivated himself in a virgin body, and not one drop of his original yang has been spent. I meant to take him off and couple with him, and so become a Golden Immortal of the Great Monad — and I never expected this ape to see through my method and carry him away."
元陽 is the original masculine vitality a man is born with and spends over a lifetime; the whole system of inner alchemy is built on not spending it. 太乙金仙 is a high rank in the Daoist heavens. Note that 修行 keeps 行 as xíng, practice — not the héng that the same character takes in the word for accumulated spiritual power, which this chapter happens not to contain at all.
Here is the plan, stated plainly, and it explains the chapter's title. The couplet at the head calls her the Fair Girl nursing the yang and seeking a mate, and this is what that means: she is an alchemist and Tripitaka is the reagent.
The idea underneath is old and coherent. Inner alchemy describes cultivation as combining a masculine and a feminine principle inside the body to refine an immortal embryo. What she proposes is to do it with an actual man who happens to be carrying ten lifetimes of untouched merit, which is the same reasoning as every other demon on this road, dressed in better theory.
It is worth being clear about what she wants, because the chapter is careful about it. The other monsters mean to eat him. She means to marry him, and by her lights that is a promotion for them both.
