There are two worlds. One is the surface world that we can see and come into contact with, and it follows the laws of materialism. The other is an inner world composed of dark matter, following the laws of idealism. The Mayans predicted that December 21, 2012 would be the end of the world.
In order to prevent the end of the world, governments of various countries secretly summoned the most outstanding scientists, engineers, technicians, soldiers, and the criminals who caused the most headaches to governments, and finally succeeded in preventing the destruction of the world. It was supposed to be a perfect ending, but Robert, a genius hacker, wanted to make the world more "interesting" by implanting an alpha virus that could evolve independently into the supercomputer that saved the world. On this day, the outer world and the inner world merged. Since then, the world has gained a new science, which obtains matter and energy from the inner world and then acts on the outer world. This science is so magical that it is named Magic. But the most powerful magician is not a human being, but a supercomputer controlled by the computer virus Alpha. The constantly evolving Alpha quickly became the manager of mankind.
When the outer world and the inner world merged, a shock exceeding the speed of light was produced, and various people returned to the past and became time travelers (general relativity). A few of them have become great men who will go down in history, and most of them are unknown. The only thing these time travelers have in common is that on the day of the end of the world, they suspect that one plus one equals two.
