Blue Star suffered an unknown heavy damage, and the human race was almost extinct, but a small number of people finally survived and left the earth to live in a space base. The protagonist was bored and discovered an intelligent system left by his predecessors, which seemed to be a game system. In order to kill time, the protagonist used a brain-computer interface to let his consciousness enter this "game world", but he found that the world inside was severely collapsed and he would be injured every time. Another person with him is a high-tech genius. They are trying to repair this "game", and then the protagonist begins to think about whether the real world they live in is also programmed by higher-dimensional creatures, and it is also false and non-existent. He is thinking that if it is virtual, why can't he jump out of the program and restart the world like a game restart? He wants to save the same kind that have died and let the world start again.
After the game was repaired, a shocking secret emerged...
Mission: Save the world, free will
