Need help looking for title:)

Please help me know the title. All i remember is. that it's a webtoon with blond male protagonist. He I. believe is an unwanted prince he became a doctor but he has like a system ( kinda forgot) that allows him to have skills of modern doctors and he is using those skills on an era where surgery is considered like heresy. My memory of this webtoon is blurry because I read it a while back but let me know if you recall reading something similar.
