The Vagabond Swordsman

Fan Kun Yang, a newly married man, worked as a travel escort. When he returned home from a job escorting a highly valued cargo, he found that his wife had been unfaithful. After abandoning her, she and his sister-in-law were killed by the same man who broke up his marriage, causing Fan to seek revenge against the murderous villain.
