Lin Fan, a senior high school student, was laughed at by his class the day before the college entrance examination. When I woke up, a mysterious sign-in system appeared in my mind. Sign in at school and get 100 million! Sign in at the hospital and gain god-level medical skills! Sign in at the martial arts gym and gain peerless martial arts! While others are still running for life, he is already on top of the world. From then on, Lin Fan started a peak life of signing in and counterattacking all the way!
