Crossing Boundaries

My name is Ye Xiaoming. A few hours ago, I jumped into the sea to save a drowning girl. In the end, the girl was saved, but I was knocked into the sea by a wave. Finally, I was exhausted and swallowed the sea water and choked to death in the sea. When I opened my eyes again, I found myself on a desert island. When I escaped from the desert island and returned to land, I realized that I had come to a different world.
