My bathroom connects to another world

In a world of swords and sorcery, most transmigrators dream of harems or ultimate power. Zhao Guang just wants a coat. Stranded in a frozen wilderness, his first priority isn't a legendary sword—it’s basic survival. But the bitter cold is only his second biggest problem. The first is the giant, razor-sharp porcupine that has inexplicably developed a very personal interest in him. Forget saving the world; Zhao Guang must figure out how to get warm and escape his persistent, prickly stalker before he becomes its next meal. A hilarious, grounded take on isekai survival.
