After falling into another world through a Gate, Lee Kang-joon conquered the vast continent of Anuk in just fifty years, rose to the throne as emperor, and ruled as its supreme being. As a 9-Circle Necromancer, he hunted dragons, hopped dimensions to wipe out the demon realm’s warlocks, and even stormed the martial world to topple the Heavenly Demon and the Alliance Chief. He searched and searched for a way back to Earth… and finally, after more than 300 years, he made it home—only for his older sister to shove a warm, squishy little life-form into his arms. “She’s your daughter. Her mom died in childbirth… Ring any bells?” “Papa!” …Wait, that was before he’d even conquered Anuk— 300 years ago, at that. “So you’re the super-powerful emperor of some continent? You were stuck in a Gate for three years, and I should be glad you’re only delusional.” Only sister or not, calling him a raving lunatic is downright rude. Still, he has to admit she’s right about one thing: “But she is your kid, so you’d better step up.” He’d planned on slipping back into a quiet, peaceful life on Earth. Now, as the ultimate being, he’ll pour every ounce of his power into paving a flower-strewn future for his daughter, Seol-i.
