Code Name Taoyuan Planet Adventure

If science is developed enough, humans will get rid of the physical body! Travel through the stars! I am telling the story of human beings getting rid of their bodies! In 2222 AD, humans were able to replicate the 16 billion neurons in the brain, so they used optical communication to start interstellar travel! I hope to write a novel like "Three-Body" that is based on the known physics discoveries and is an appropriate extension.
