老王 Gradually shook off the confusion and sat up, the head was a little dizzy, as if there was a pebble in the head. He saw the white ceiling before him, and a window on the opposite side. The sky outside the window was grey, unable to see clearly.

“Where am I?” Old Wang frowned and muttered to himself, “This place looks like a hospital room.” He looked around the room and found no one around. He got up and went to the door, opened it and saw he was in a hospital corridor. There were several similar rooms on both sides of the corridor. He felt a bit confused, but soon found a sign on the wall: “Genetic Evolution Department.”

“Genetic Evolution Department?” Old Wang felt even more puzzled. “What’s that about? Did I get into a hospital for some weird reason?”

He walked into a nearby room and saw a doctor there. The doctor had a kind smile and said, “You’re awake. How are you feeling?”

Old Wang replied, “I’m fine, but I don’t remember what happened. Where am I?”
