Reborn as a Ninth-Generation Demon, Stay Away, Coldhearted Demon Lord

Lin Mojiao, a highly educated corporate drone, suffers a sudden heart attack and is reborn as a thoroughly respectable demon several generations into a noble family of the Demon Realm. The shameless Heavenly Pillar sees her as the world's savior, turns into her lackey and permanent hanger-on, and pesters her every day to save the world. The cold-faced Demon Lord is aloof and ruthless, with a mysterious past. He seems destined to become the great demon who destroys the world, the kind who makes even the Heavenly Pillar tremble. Little demon princess Lin Mojiao rises from the terror of her clan to the terror of the Demon Palace and then to the terror of the world. With her lackey, the Heavenly Pillar, at her side, she builds infrastructure, opens up new lands, flirts with handsome men, and brings peace to a chaotic age. But why does the cold-hearted Demon Lord keep sticking to me? Don't you have an enchanting demon attendant, the Immortal Emperor's niece, the demon clan's princess, and so on? The Heavenly Pillar, her lackey: Just let him cling to you. If he gets to cling to you, he won't go crazy... The Demon Realm's cold-faced, flirtatious big boss vs. a high-quality, independent, down-to-earth woman from modern society
