I'm looking for a manga. It was an ancient chinese setting manga. FL was a maid who was sold in the imperial harems. FL was raised in a brothel. And FL used to experiment a lot with medicine and poisons and so was immune to poisons. Oh and she used make up to make herself more ugly. Initially FL was a normal maid but then she started serving one of the 4 most noble imperial concubines and even became a poison tester.
