My Fireplace Ships to Dragon Realm

Heiress Emily, hunted by greedy relatives for her inheritance, flees to a rustic farm. There, she uncovers a fireplace that opens to a dragon world. Sending modern goods—firewood, medicine, even firearms—she aids the metallic dragon lord Kael in defending his clan. Seen as a "Dragon God," she reshapes an entire war and, in turn, rewrites her own destiny.
