Two Men (Best, but Romance Is Also Acceptable) Slow-Burning, Old-Fashioned, Power-Seeking

I would like to read a book similar to "Cheng He Ti Tong: Complete Two Volumes". Super brain-burning or super funny. It's best to have both. Don't have too many emotional lines. It's best to be in the monarch-subordinate, master-slave category. Is there any? Please, if there are no twins, the romance won't be a big problem.
