Xiang Ye is abruptly summoned from modern Earth into a hostile fantasy realm torn by a brutal war between the human race and the demon clan. He materializes beside Isabella Oser, the legitimate Demon Queen, who has been betrayed by her ambitious general, stripped of her royal power, and forced into hiding in a weakened form under the pseudonym Yi Bei. Because Xiang Ye lacks innate magical aptitude in a world dominated by raw elemental affinities, he is initially regarded as completely useless. To survive execution by hostile human factions and avoid detection by demon assassins, Xiang Ye and Isabella enter into a contractual marriage of mutual convenience.

Refusing to remain a helpless liability, Xiang Ye enrolls alongside Yi Bei in the Imperial Magic Academy. While conventional mages chant spells and channel raw elemental mana, Xiang Ye discovers an affinity for Forging Magic, an overlooked discipline that materializes physical constructs from structured blueprints. By combining Earth's mechanical principles, chemistry, software logic, and ballistic engineering with magical ink, he creates combat exoskeletons, automated firearms, artillery systems, and mechanical titans that counter high-ranking mages. What begins as a desperate bid to survive escalates into a campaign across the Imperial Tournament, the defense of human borders, and the reclaiming of the Demon Throne.

What to Expect

My Wife is the Demon Queen structures its progression around intellectual tactics rather than inherited divine gifts. The narrative opens with an Academy Enrollment Arc that establishes the rules of creation magic, transitions into the high-stakes Imperial Tournament Arc, and expands into large-scale warfare spanning the Demon Realm Expedition and the Final Continental War. Readers follow a calculated escalation where combat relies on real-world physics, industrial design, and defensive planning. The central romantic dynamic develops as a steady partnership based on tactical trust and mutual protection.
