Lu Yuan always thought that he was an ordinary bookstore owner, until that day, he found a page of golden text in a newly arrived ancient book. The moment he touched those words, the world completely changed in his eyes - faint codes appeared above everyone's head, and for those who were called "travelers," the codes were particularly bright.
He became a "travel observer" and could see the golden instructions that determined the fate of each traveler. But when he wanted to save a time traveler girl who was about to be deleted by the system, he touched her code and saw the chilling truth: there was an image in her memory that did not belong to this world, and there were countless identical "hers" repeating similar fates in different worlds.
It turns out that time travel is never an accident. Every time traveler is a character carefully designed by higher-dimensional beings. Their adventures, systems, and cheats are just preset programs. And Lu Yuan's status as an "observer" is just a variable in this large-scale experiment.
Now, the system has discovered this exception. The erasure process is being initiated, and the Correctors of the Cross-Administration are approaching. Before being eliminated by the system, Lu Yuan must find the ultimate truth behind time travel with the girl who should not exist - perhaps the real time travel is never about crossing the world, but about waking up from the programmed destiny.
