From the introduction:
Welcome to the wonderful world of Trinity Wonder. A technological future soon to be invaded by a powerful Murim expert and a powerful Fantasy mage, after a teleportation gate experiment goes wrong. What the buxom scientist who built it did not, and perhaps could not, know was that this gate linked to other worlds entirely. Unfortunately, after crossing over, a misunderstanding leads to them accidentally destroying the gate while fighting each other and now these two warriors must live in this strange new world with the scientist that brought them there, while she rebuilds the gate that will allow them to return home. Wujin, the cocky righteous Dragon God of the Murim world and Emily, mage with a mission and disciple of the famous Highwalker, soon find that the enemies they left behind aren’t as far away as they thought, and seedy people in the dark begin to plot against them. Sylvia, a genius set on finishing her deceased father's lifelong project, must now deal with the wacky shenanigans of her new companions as she is pulled into a world far out of her element. You will be arriving in this jump at the same time as Wujin and Emily are pulled through the Quantum Portal.
