both are costume dramas with beautiful visuals and fantasy elements centering around a female assassin and a man who would do anything for her. the female leads are both incredibly strong women with tragic backgrounds whose desire to survive drive them forward. one difference would be that in alchemy of souls, the fl is the teacher and the ml the student, while in bloody romance it's the other way around. alchemy of souls is also more lighthearted than bloody romance, but both dramas do get dark at points.
Although both dramas could be considered vastly different and have different vibes, there are similar elements.
1. Female leads who gain strength through diversities to reach their destinations.
2. Strong lead chemistry.
3. Second male lead develops feelings towards female lead.
4. Supporting characters who make unexpected sacrifices to aid lead female.
5. A bittersweet ending.
I recommend these dramas if you liked either of them. Princess Wei Young is slightly more romantic and typical historical drama while Bloody Romance is unique and stands alone from others I have seen while still having a similar love story.
