Excellent Sign-In System

What should I do if I become a useless person through time travel, am framed by others and have my meridians disabled and unable to practice, and am exiled to clean the cemetery? Don't be afraid, the golden finger is activated the moment Lin Chong enters the cemetery. "The best sign-in system has been deployed!" "Succeeded in signing in and obtained the top skill, the Twelve Star Heavenly Palace Sword Technique!" "Sign in successfully and get the best sword, Qingfeng Sword!" Adhering to Voldemort's principles, no one can interrupt me signing in. Even Lin Chong himself didn't know how strong he was during the hundred years since I signed in. Rushing out of the universe, pointing the sword at countless planes, "Who else is there?" This novel and its characters are purely fictitious.
