From Knight of All Laws to Wizard of All Laws

Overwork and a sudden overtime shift send Rayne crashing into a backward world—one where even nobles lack proper toilet paper. At first glance, it seems like a crude medieval knockoff. But slowly, he realizes this place is far stranger than it appears. Beneath its rustic, European-style surface, gods genuinely exist. Worse, this is a forsaken land. Aside from the Knight and Cleric paths, any profession that touches the supernatural is branded heresy. Dragons, elves, and dwarves have all been reclassified as dark creatures—and witches and wizards do not exist at all. Monsters rampage, holy spirits weep. Then the wizard arrives. Who says nothing is immortal? The cheat tool called "Yuanbao," which Rayne had stayed up late coding back in his own world, inevitably becomes his greatest asset—and the key that transforms him from a knight of all laws into a wizard of all laws.
