I Took in a Taoist Priest as My Master

Ryan was just a poor dockworker who hauled crates, living in a drafty attic in the lower city. All he ever thought about was whether he had enough bread for today and could scrape together next month's rent. Until that rainy night. Someone paid him three gold coins to escort a noblewoman, and he stumbled into a deadly assassination attempt. Bullets whizzed past his ears as he ran through a hail of gunfire, with a semitransparent old man with a white beard floating behind him. The bullets passed straight through the old man without even brushing his robes. “I am Daoist Xuan Qing. There is no need to be so nervous, young friend.” This world had magic, knights, and priests. High above, aloof gods ruled the heavens. Having failed his tribulation, the True Immortal Xuan Qing's soul had drifted into this otherworld. He said, “Call me Master, and I will teach you skills that reach to the heavens and plumb the depths of the earth.” Ryan had only wanted to make rent and feed the dozen or so children at the orphanage. Then he discovered that people in this world could live their whole lives without ever knowing there was another kind of power between heaven and earth.
