I'm unbeatable at extracting skills from celebrities

Reborn with a so-called cheat system, Jiang Nan expected miracles—what he gets instead is a stream of faint, glowing prompts offering him "elite skills" harvested from celebrities. There is a male star with skin of absolute steel, so shameless he mooched free meals for 405 consecutive days without so much as a blush. There is a comedian with a legendary tolerance, a man who downed 27 bottles of beer back-to-back and still brimmed with energy. There is a silver-tongued heartthrob who juggles four girlfriends at once yet never once stumbles into a love triangle. And there is a pop diva whose "unparalleled" mahjong talent once earned her a remarkable record: 47 straight days at the table without winning a single hand. After every absurd entry comes the same inviting question—should he extract this skill? Staring at the barely visible words floating in the air before him, Jiang Nan can only feel utterly bewildered. What is any of this supposed to mean? Freeloading, binge-drinking, two-timing, and losing at mahjong—is this truly the best his rebirth has to offer? As the dubious offers keep piling up, one gnawing doubt takes hold: can this so-called cheat system of his actually be trusted?!
