I Have a God-Level Sign-In System in Swallowing Starry Sky

When Chen Fan was in a car accident, he just opened his eyes and saw a big bloody mouth biting him. After killing the tiger, he was bound to the god-level sign-in system. It turned out that the system transported him to the world of devouring, but this system is not ordinary. It is either annoying or irritating people. However, the system is still very powerful. The magic and skills given by daily, weekly, monthly, and yearly sign-ins cannot be stopped.
