Traveling Through History: All Those Who Return Have Special Powers

[Science fiction apocalypse + wasteland travel + return ability] Every time you go back to the past, you may bring back a kind of strength. It might also make you disappear from everyone's memory. In the 115th year of the Gray Dome, the surface of the earth was reduced to wasteland. After the disaster, humans reestablished order around the four doors. The door can send people's consciousness into the past, allowing the person who opened the door to wake up with another identity in history. Very few people can return and bring back a special ability from that era that is not of this world. But history is never allowed to be rewritten at will. When a period of cause and effect deviates too far, correction begins. The name in the file disappeared, traces of his life were erased, and people who knew him gradually lost all memories of him. It was as if this man's life was just a page dropped from history. Ji Heng gradually discovered that the four doors are not the hope shared by mankind. Some people use it to change history, some monopolize the ability to bring back returnees, some are responsible for selecting those who are sent away, and some are responsible for making the losers completely disappear from everyone's memory. In order to retrieve those people who have been forgotten by the world, and to know where his parents have gone, Ji Heng must enter the history behind the door. But when various forces began to compete for the next goal, what he really wanted to win was more than just a return qualification. But the four doors themselves. He wants to seize the door. From now on, who will be sent into history, who can return with strength, and who will become the next "falling page"—— It should no longer be decided by those people.
