Ye Feng, a traveler in the parallel world, accidentally awakened the god-level sign-in system after becoming an ordinary security guard at Jinghua University. By signing in anywhere on campus, he can unlock all-round skills such as physics, mathematics, piano, medicine, and design. He amazes all the professors in the school with his strength. He is eager to be recruited but he only wants to be a security guard. He is also pursued by the school belle Su Mengxue. Ye Feng cheated all the way, easily solved family difficulties, slapped those who mocked him in the face, and became a campus legend as a security guard. In the end, even the principal tried his best to retain him, and started a counterattack life.
