Rebirth Changed My Life Ten Years Ago

My name is Qin Xiaoyun, I am 23 years old this year, and an ordinary person has become a time traveler. During my physical examination, the doctor told me that there was something wrong with my heart and suggested that I go to the hospital for a heart checkup. I didn't pay much attention to it, so I didn't go. As a result, I went back to ten years ago. "Hello, host, I am your learning and earning system. My code name is 001. From now on, 001 will serve you." No, there is also a golden finger. This is an unexpected surprise!
