In the empire's era of peace, Alphas symbolize wealth and status. Ning Suiyuan, an obscure Beta, faces constant bullying and is forced to survive under the protection of the empire's top elite Alpha, Ji Heng. When the apocalypse strikes, Ji Heng defies opposition and promotes Ning Suiyuan to his ranks. Dissatisfied, the Alphas spread rumors of their underhanded dealings. Until Ning Suiyuan emerges from the smoke of battle like an unstoppable blade, tossing two broken flame guns to the ground with icy disdain: "Don’t you have a more durable model?" The Alphas are stunned: *We were blind! Our minds were filthy! Sir Ji is just and wise, and Brother Yuan is a fucking legend!* Only later do they realize—the great demon king had merely awakened from slumber. --- Half a year after the crisis is quelled, Administrator Ning skips his inauguration. When questioned, his closest ally Ji Heng smiles and explains: *Don’t worry, he just miscalculated his heat cycle.* The crowd: *?* Shocking news! The god-tier Beta who dominated countless Alphas—*Ning Suiyuan isn’t a Beta at all!* He’s an *Omega!!!* Ning Suiyuan will always remember that rainy night of sudden differentiation. Surrounded by enemies, the Alpha kissed the nape of his neck and whispered tenderly: *"Let me bite you, and you’ll live."* --- **Pairing:** Unshakably dominant instructor Alpha (top) × Genius-level battle maniac with a pure heart (bottom). **Content Notes:** 1. ABO / No mpreg / AO pairing / 1V1. 2. Futuristic setting, light cyberpunk, abundant headcanons, dual plot-romance arcs. 3. *This is fiction, not an encyclopedia. Simplified lore avoids disrupting immersion—not because the author is clueless. No nitpicking or pedantry, thanks.* ---
