Past Events in 1999

I just wrote what was in my head and now the story is complete. I will learn other people's writing skills in the future and try to write a medium-length novel next time. The story of "Back in 1999" actually has a lot of room for filling in, including the costumes of the characters and the description of the battle scenes. I really have no experience with this, so I won't write it down to make everyone sick. And just like the last paragraph of the story, should we reflect on whether continuing to have endless wars and destroying the environment will usher in the end of mankind? Personally, I am pessimistic about the beautiful country's behavior. I hope this little story can give you something to think about.
