I really want to have a 400-word composition about the elixir of life.

I don't want to die, because people turn to ashes after death, and I will never see this beautiful world again: the Great Wall and the Forbidden City in China, the pyramids and the Sphinx in Egypt, the Statue of Liberty and the Empire State Building in the United States, the beautiful sunset glow, endless mountains, the blue sea, lovely butterfly fish, fierce sharks, beautiful corals and shells ... If I can live forever, I can always see these charming scenery, and.

However, human life is limited. I want to invent an elixir of life so that I can live in this beautiful world forever. Many scientists all over the world are studying the elixir of life, but so far no one has succeeded.

I am determined to study hard and accumulate rich knowledge. Finally, I personally invented the elixir of life. This is my great dream!
