Release that Witch

A modern-day engineer finds himself transmigrated into a different world, taking on the role of a prince. Though his new surroundings resemble medieval Europe, they are far from a perfect mirror. In this realm, witches are real and wield genuine magical abilities—abilities that, remarkably, can be harnessed as a productive force. To secure their survival and fully unlock their potential, he must navigate uncharted territories, repel demonic forces, untangle a web of conspiracy, and steadily advance the technological tree.
