The Ninth Imperial Uncle Is Mighty

She is a smiling assassin, a genius at reading people, and can swindle anyone while chatting and laughing. But after she transmigrates, an older man gets the better of her. If she doesn't get even, then her name isn't Ye Qinghuan! Unexpectedly, by a twist of fate, he mistakes her for the beloved little niece he's been searching for, and spoils her rotten. In that case... she'll just spend his money, use his influence, rule the world, and do whatever she wants! “Uncle Ninth, could you keep the princess in check?” Even the neighboring kingdom's prince is at his wit's end. The princess really shouldn't stick her nose into everything. Uncle Ninth casually raises a sleeve, a dazzling smile on his face. “Didn't you know? She's the one who keeps me in check.” The neighboring prince nearly faints!
