Miracle Doctor Sign-In System

"Ding, system check-in time." Yang Hang's cell phone suddenly made a sound. "Sign in?" Yang Hang took the phone and there was a sign-in button on it. He clicked it. "Sign in successfully and get three experience beans." Three more beans appeared out of thin air in Yang Hang's hand, and he swallowed them without thinking. "Ding, increase your experience by 300 points and be successfully promoted to an ordinary doctor." In an instant, countless experiences about treatment and physical therapy poured into Yang Hang's mind. "This... I become a doctor?" Yang Hang asked himself in disbelief. He looked at his hand, which had been scratched when changing a light bulb a few days ago and was now slightly swollen. "The needle should be inserted half an inch, and the needle should be removed after a while." Yang Hang didn't know how he knew these things, but he did the right thing. His hand was healing at a speed that was visible to the naked eye. "Wow, I'm a doctor!" He has long heard from others that doctors are one of the most profitable professions. I want to be the most awesome doctor! Yang Hang thought so. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
