Su Yi, an ordinary young man, unexpectedly has the ability to travel between two worlds, and becomes attached to Wuchan Naga, a girl from another world. He started by reselling ginseng from another world, but found that electric energy could speed up the practice of divine thunder skills. While Su Yi manages trade between the two worlds to accumulate strength, he protects Naga through dangerous situations, walking side by side on the road of commerce and martial arts. He won trust with his wisdom and sincerity, and finally joined hands with Naga to live out his own light between the two worlds.
