The Years the Demon King Went Undercover Himself

Weakest Demon King (Female Lead) x Strongest Hero (Male Lead) Crossed out: Career-minded demon king spy x Love-struck, scheming hero ★ If the Demon King doesn't corrupt at least one hero, it feels like she hasn't unlocked her pinned achievement! ★ Story arcs: Imperial Academy (this section is quite long) → Elven Forest → Wasteland → The Demon King Returns As the only surviving demon species in the present world, Anta was undoubtedly destined to become the next ruler of the Demon God Cavern, the strongest demon in the demon realm, and a terrifying final boss. Anta, who had transmigrated here: Give me a break. Just look at that Lv. 0 over my head. I'd have to scrape by just to take on a slime one-on-one! Then she took a look at the other side's lineup: a Lv. 85 elven swordsman, a Lv. 63 white mage, and a Lv. 30 apprentice hero. Wait, an apprentice hero? He's clearly about her age, so why does his level start at 30!? Shivering, Anta clutched her secret identity close and resolved to diligently work as a demon-world spy by the hero's side. After years of patiently biding her time, Anta had finally built up her strength and returned to the Demon God Cavern. She'd thought she was coming home to a happy place, but the reality was a barren wasteland full of troublemakers. They claimed that a million-strong demon army was waiting for her triumphant return so she could rule the human world. In reality, they'd been stuck underground eating scraps for so long that they were craving the rich food of the human world! What's more, these so-called "high-ranking demons" couldn't even take a single punch from the hero! Not one of them could put up a fight! Jemitt, who'd been promoted from apprentice hero to full-time hero: "So you're the ones who kidnapped my fiancée? Hmm?" The demons, beaten and scattered, shook their heads. "She came back on her own!" Anta: "Who's your fiancée?! You scheming wolf in sheep's clothing, stay away from me!" -The premium chapters start at Chapter 50.
