Reborn, I Trained My Underachiever Dad to Get into Tsinghua

Jiang Qixing, the only son of Jiangcheng's richest man, was rebellious and ruthless, and no one dared cross him. Yet a little girl who appeared out of nowhere called him Dad, and had him wrapped around her little finger, with no way to resist. Jiang Qixing, who'd suddenly become a dad: “...?” He'd never even held a girl's hand. How could he have a daughter this old? The little girl was adorable and pretty, but unfortunately, she had quite a mouth on her. “Daddy, being late isn't what good kids do. Hurry up and get up!” “Daddy, fighting will get you hurt. Stop it!” “Daddy, people who are better than you work even harder. What excuse do you have for not studying?” “Daddy...” Jiang Qixing was at his wit's end. “Master, stop lecturing me! I'll do what you say!” Everyone noticed that one day, a little girl like a living doll had suddenly appeared by Jiang Qixing's side. Whenever he spoke to her, he would bend down to her level, smile at her, and treat her with a tenderness, patience, and affection she'd never known before. One day, when he received an acceptance letter from a top university, Jiang Qixing was stunned. So he really could be this good. * Tangtang was the most popular little girl around. Jiang Qixing wanted to protect her around the clock so some little wolf cub wouldn't snatch her away. But then... The dark-hearted young man smiled at Tangtang, looking utterly innocent and harmless, his voice as gentle as could be. “Tangtang, I'm a bad person, really bad. I need someone to keep me in line. So, do you want to keep me in line?” Let me be yours for life. * System: ? The little girl's cultivation path was supposed to turn her into a dark, villainous antagonist. How did she end up becoming everyone's beloved sweetheart? I'm quitting! [An adorable, sweet, well-behaved lucky-charm girl X A master of tea and a dark-hearted devil with a gentle facade]
