This is a world where immortality and science fiction coexist. The world view is relatively large and there are many group portraits. This is a work that the author has conceived for a long time, but may not have enough knowledge. Readers are welcome to give their opinions. If you are interested, you can also share the OC with me. I will try my best to restore the character's personality. I am really missing a name. Thank you! Also, some pitfalls may be filled in later, so don't be anxious.
