This meant that the counterfeit rusty disc in this room hadn't always been here; it had only appeared today, deliberately switched by someone. This swap was extremely secretive, and the average person would have no clue that it had taken place. Moreover, Yan Fei had discovered from the traces left at the scene that there was no sign of others having gotten there first, snatching the real target and replacing it with a fake one to deceive those who would come later.
Then Yan Fei deduced that the one who had replaced the rusty disc was not just anyone, but a high-ranking manager within the Louvre Museum. In other words, the whole fuss about the rusty disc appearing in the Louvre Museum was actually a conspiracy, aimed at luring those interested in the rusty disc, like himself, and then catching everyone in one go. Although he did not know why they would target people interested in this kind of object, Yan Fei immediately realized that he was in danger.
