Zhang Lin, a college student, had a bright future, but he was maliciously framed by his ex-girlfriend and a rich second generation. Not only was he expelled from the school, but he was also stigmatized and fell into the bottom of the valley. With no other way out, he had to work as a door-to-door technician to make a living. In a desperate situation, he accidentally awakened the card technician system. With professional services, he accumulated favorability and unlocked various skill cards and wealth rewards. Zhang Lin, who was becoming more and more mature, no longer held back, and fought back forcefully against his former enemies step by step, making their conspiracy and faces known to the public, and slapped them in the face with pleasure. In the end, he counterattacked and transformed, sitting on huge wealth but keeping a low profile, becoming an awe-inspiring invisible rich man, and truly reached the pinnacle of life.
