Oldman by Chang Sheng
Action Drama Fantasy Historical Mature Shounen
Awarded in the 6th International Manga Award by the Japanese Government (Ref), and based on the first 3 chapter already available in the web, this Taiwanese comic promises to be a must read. You can read the first and second chapter in Batoto, and the second (a different version) and third chapter on imgur. An scanlator is just taking it.
