Dicky is a graduate student in theoretical physics. His girlfriend died in a car accident when she was driving out on Christmas Eve. Someone asked him if he would like to time travel back to before the car accident, but the male protagonist was immediately arrested by the Time Security Bureau after returning. It turns out that this kind of time stowaway had already appeared in 1965, but due to a conflict in the timeline. For every time visitor, a contemporary disappears. What's even more frightening is that if everyone in a person's social circle disappears, this person forgotten by the times will be erased from the timeline. With more and more time stowaways, the entire human civilization will be ruined. The Security Council sends the male protagonist back to the future to try to save humanity. After the male protagonist woke up from the hospital in 2048, he found that human beings were still surviving stably. The entire human society has entered a great trough era and lost all order. Beginning in 2035, humans will pursue art and worldly joy again. However, due to the conflict of the laws of time, a large number of timelines were intertwined and wiped out a large number of human beings. Dicky made a desperate move and came to 2175, and found that humans all over the world had disappeared. Only Adam, who claimed to be the creator, was left. Now, who lives and who dies among all the creatures in the timeline all depends on his thoughts. Dicky used his last shuttle opportunity to go to the beginning of creation, killing the ancient apes, the ancestors of mankind, and completely erasing human civilization in the timeline, making human civilization no longer an experiment but a splendid civilization that never existed.
