After a Wage Slave Became the Dark Lord

In one sentence: There's no way I'm getting a job. I'll just raise some evil creatures instead. [Slice of life / comedy / sweet and satisfying] [Yandere demon butler x stingy, comedic lord] When the doors of the last subway train opened, Su Qiu transmigrated. A man in a black tailcoat knelt on one knee, his voice low and magnetic. "Welcome home, my Dark Lord." "Dark Manor is in ruins. The evil creatures are eagerly awaiting your return, hoping you'll lead them to glory once more." "Please swear an oath of blood upon the Abyssal Evil Codex and break the seal of the God of Light." Su Qiu: "???" I've run into a pervert. Better call the police. Ding-dong. Her phone suddenly rang out in the empty station. "Your Abyssal Evil Codex has been delivered. Please check your messages." Su Qiu glanced down at the bloody skull on her screen: "..." Damn, my phone's got a virus! I just spent more than half a month's salary on it!!! At first, Su Qiu thought that being a lord meant she wouldn't have to work. Later, she discovered that was true. But her daily routine had become a series of roars and scoldings: Admonishing the fire-breathing dragons: "You're huge and mighty. Humans are not your food!" Scolding the three-headed dog with the brain of a husky: "I've said this eight hundred times! Who the hell took apart the differential analyzer in the storeroom again?!" Clinging to the leg of her spendthrift Dark Butler, she wept tears like noodles: "Please, don't buy me any more pretty but useless dresses! The goblins work so, so hard mining ore!" Charles took off his white gloves and smiled elegantly. "It seems I was far too lenient with those lowly abyssal creatures. Now they've even learned to complain to you." Theme: For love and peace
