Hi so I am trying to remember the name of this novel where an Assassin is reincarnated into a cultivation world and he takes over the body of a young master who was exiled for raping a princess, he has the cultivation technique from his past life and he found that he can use it in the new world alongside their magic cultivation technique. I can't remember much except he had several partners and one of them is a light mage who has a birthmark he sees when she is bathing and he lies and pretends he didn't see anything. Any help would be great.
