An Arknights Villain, but a Wicked Little Wizard

(Not the actual hero. The protagonist has a somewhat unhinged, Veigar-like personality. Durin. Harem-focused. Only loads the System. The author has already completed an 820,000-character group project, Deep-Sea Hunter, but a Deep-Sea Titan.) You land-dwelling yokels! I, the great evil wizard Veigar, have come to enslave you! From now on, you'll work a full eight hours every day, get only three meals and beer, and have just one hour for lunch! Hahaha, you'll work yourselves to death! (Haki Veigar's terrifying evil laugh.) Admit it! I'm the de-vil! (But somehow, the atmosphere became much more cheerful.) No laughing! (Veigar, on the verge of tears, enters Spinosaurus form.) (P.S. This book is also known as Veigar's Kindness Can Never Be Repaid in a Lifetime, Little Durin Takes the Wheel, and Durin Jokes Are Terra's Cultural Heritage.)
