Lazy Dungeon Master - Chapter 267

When an S-class elite assassin-raised captain of a special ops suicide squad comes home from a high-stakes Africa mission, he finds himself offered something that could potentially set him up for life- a curious assignment that he could use to finally exit his days of war and slaughter.

Then placed into a high-school setting, Lin Yi is tasked by the chairman of a top-tier multi-billion company with bodyguard duty for non-other than his own daughter, a certain little Miss of said high-school.

His enemies, once ranging from drug lords, mafia bosses, political figures, and national leaders, are soon replaced with spoiled kids who happen to have rich papas and mamas, and Lin Yi finds his intense expertise and high-threat skillset misused, and very underwhelmed…

But he does get a harem cast as diverse as his old enemies, so Lin Yi decides that, for the sake of messing around with girls as an invincible entity in a down-leveled environment, leaving his bloody and death-filled war days behind is something he’d definitely want to strive for.

Mimizuku, a small girl with chains on her wrists and ankles and the numbers “332” branded onto her forehead, wanders into the Forest of Night seeking to be eaten by a monster. However, when the ruler of the monsters, the mysterious and beautiful “King of Night,” refuses to eat her, she tries to formulate a way to convince him otherwise.

Han Dong works as an extra as well as a fortuneteller who foretells marriage fortunes extremely accurately. One day, he accidentally foretells his own fortune and discovers that he and a Mr. Golden will become “a match predestined by fate”. As a straight man, he doesn’t hesitate to ruin his image in front of Mr. Golden — acting as a fool, a despicable man, making himself as annoying as possible because he is afraid that the other man will take a liking to him.

Ever since she transmigrated, she was blessed with an inbuilt anti-poison detector.
