My System Requires Male Disguise

Yun Xiao, the perpetually bored daughter of the Lord of Three Thousand Worlds, gets a rude awakening. A quirky System drags her across realities, forcing her into the most humiliating role imaginable: \"Best Male No. N.\" Her mission? Prevent formidable villains from spiraling into total darkness. There’s just one problem: she has to do it while disguised as a man, navigating everything from awkward school locker rooms to cutthroat idol stages. Armed with a sharp tongue and an arsenal of hidden 'golden fingers,' she’s determined to complete her tasks. But when every single villain turns out to be her infuriating childhood nemesis, chasing her through worlds with a suspicious glint in his eye, Yun Xiao realizes saving them might be easier than keeping her true identity a secret!
