I only remember this one scene, it was talking about how the last dragon, a golden dragon fell in love with a human and they had a child, later on the child fell in love with a woman and asked the dragon to give him one of his bones, the dragon did and created a sword, later on the dragon sacrificed his life for the son so that he could become king or something, it’s not the main plot but it’s like a history lesson (someone please tell me they know i don’t wanna download reddit to ask )

Idk if this is it but I remember reading something similar to your description
it’s a classic daddy daughter manhwa and the duke or whatever was gonna adopt a girl but she needed to go through a special test, and the test was in a room and she was all like “this is a piece of cake” and the instructor guy was like “omg no way how?! this is impossible to solve!!” and then it turns out the instructor was evil and was hiding bodies or something in that room behind a bookshelf and he thought to himself “thank god she didn’t (instead doing something) or i would have been found out” also he had long white hair. please guys anyone please i need to know or i will die!!!!!
I don’t really think this is it but it’s worth a shot

yeah, the white haired villain was the right hand man of the duke, and the duke was seeking to adopt a kid so they had multiple kids coming and going to do the test but none of them passed, the test was a room, and it seemed like they had to just sit there or do something but only some kids found out the true test was to look around and find something?? the female lead was the only one who passed which got her adopted. the villain was the one who conducted the tests, i remember her wore glasses but when he showed his evil side or whatever he would take them off. i think we was conducting human experiments and OH he was a mage!!
I’m pretty sure it’s this
