Things I remember: MC's name starts with the letter 'A'. (I think) MC's has a genius sister and I believe it was something related to healing ability. MC has a system set by his past life which helps him. MC is using/training/practicing something called Origin and hides it from others. MC's mother is a noble (but actually she is one of his descendants from his past life) and I believe she was dead at the beginning of the novel. His father neglects him I can't quite remember if it was a cultivation novel or western fantasy novel. Lastly, MC is watched by someone powerful (which turns out to be his past life's friend) Please let me know if you remember a novel like this. Thank you, have a good day.
Thank you Omegataku! I was searching for this last night and I was so frustrated that I couldn't find it. Have a great day my friend.
