After saving Lee Rang, Lee Yeon fails to return to the present, so he visits Taluipa of the 1930s, who asks him to work for her until the Gate of Time reopens. Under Taluipa's orders, both brothers board a train to find the Legendary Pipe. Inside the train is a woman who prepares to greet Lee Yeon, Shinju who devises an escape plan, and an hourglass that indicates the approaching overpass.
