While Others Cultivate Bitterly, I Pre-Make Essence and Blood to Become an Emperor

Fantasy, Wild Imagination, and a Vast Worldbuilding. Get It?

Looking for books similar to "You Were Supposed to Support Your Master in His Old Age, So Why Is He Seeing You Off Instead?" I want a fantasy novel that's not the traditional kind. A childhood betrothal is fine, but the woman shouldn't break off the engagement. The sect's senior figures and disciples should be smart. No harem. There should be an upper realm.
