The patent for artificial Adrenochrome and simple logic will lead you to the conclusion that elite rich and powerful people are torturing and consuming children.
In ancient times we know that priests and powerful people drank the blood of children and said it gave them powers.
If that ritual fell out of practice we would all assume they were crazy and never have been currently interested in doing experiments to recreate adrenochrome.
The fact that we went to the effort to recreate adrenochrome means we were obviously very aware that these old rituals weren't crazy. How did we know that these rituals actually worked and were worth spending millions to recreate?
Because it obviously didn't fall out of practice even into our modern 21st century. It is OBVIOUS, its simple...its logic.
