Signing In to Nine Goddess Sisters from the Start

Chen Mo got his hands on an incredibly powerful System. From the start, he signed in and got nine gorgeous older sisters! Eldest sister: founder of a five-star hotel. Second sister: a supercar racing champion. Third sister: a PhD in biology. Fourth sister: the youngest hospital director. Fifth sister: a female warrior. Sixth sister: the gambling queen. Seventh sister: a livestreaming star. Eighth sister: lead singer of a girl group and a top star. Ninth sister: a fashionista. All his sisters are ten-out-of-ten brocons who spoil him without limits. Other people get stronger through hard work, but Chen Mo is different: he gets stronger just by signing in. And he gets ridiculously strong!
