Late Review: 4.5 semi-peak Down to heart good Medical Specialist is Isekai'd in an old era Korean world of the far past. Nothing magical here, it's just an ordinary world with basic facilities of it's time? His specialization lies with medical vision of being able to see internal problems others can't. Plus he isn't totally reliant on it, he still retains his skills previously. Combine that with a slow paced massive scale story with excellent characters plus development. As of this moment, I believe this is the longest running Medical Manhwa so far. Almost all other series got axed due to lack of popularity
