Ye Chen was an ordinary food delivery rider, until he discovered that he could see the “qi” invisible to everyone else. A mysterious order headed to the old part of town accidentally drew him into the undercurrents of the cultivation world. From then on, he delivered food by day and “spiritual energy” by night, racing back and forth between the ordinary world and the hidden realm of cultivators. But he gradually realized that the boundary between the two worlds was far more blurred than he had imagined.
