Before writing all of this, I thought about it for a long time because many things cannot be explained in just a few words. Some things I still don't understand to this day, and many things do not fit with the worldview of that time and should not have been passed down to future generations.

And the reason why I decided to write it down in the end, is because I feel that if I don't say it out loud, it would be a regret and it would be irresponsible to certain people and even history.

I am a retired geologist who used to belong to the People's Liberation Army Geological Prospecting Engineering Corps. In those red and crazy years, we were lucky and unfortunate enough to be outside the storm of the "Great Revolution" and wandered through the mountains and rivers of China, searching for the buried wealth underground. In the 20-year exploration life, we traversed 80% of China's uninhabited areas, experiencing extreme boredom and hardship, as well as encountering many incredible and inexplicable things. And these are things that you can never see in file records. They are all "should not exist" facts that have been permanently sealed.

"Some of these things are my own personal experiences, and some are things I have heard from older comrades. Many of us have kept our oaths from back then and have not made these things public. I cannot describe them in a journalistic way, so please remember that what you are reading is just a novel."
