My Life in the Courtyard

"Ding, the sign-in system was successfully activated!" The system's voice suddenly sounded in Ye Fan's mind. "Here I go, there is actually a system!" Ye Fan looked confused. You must know that he originally just had the idea of giving it a try, but he didn't expect that he actually succeeded! "System, what functions do you have?" Ye Fan asked again. "This system is called the sign-in system. The host only needs to sign in every day to get various rewards!" "Signing is divided into daily signing, ten-day signing, hundred-day signing, thousand-day signing, ten thousand-day signing..." "In addition, the system has detected that the host has not signed in for 20 years. Should we start re-signing now?" This novel and its characters are purely fictitious.
