(Another world, little girl, behind the scenes, transmigration, probably invincible, pretending to be weak while hiding her strength, one female lead with no harem, everyone misinterprets things, and she has no idea) After transmigrating to another world, Lin Xiao is forced to become a ruthless little boss who barely says a word. She blocks a fatal attack with a blank face (because she's terrified), and the werewolves cry, “We pay our respects, my lord!” She nods silently (because she can't understand them), and the elves say, “Thank you for taking us in!” She complains in Chinese, and everyone declares, “This must be an ancient secret language!” Lin Xiao: “I'm forced to lie flat and pretend to be a big shot.”
