Before allowing the foreign girl to take the stage, Yan Fei had utilized the Artificial Intelligence "Dream" to investigate her identity, ensuring that it was legitimate. Yan Fei did not detect any abnormalities or threats on the foreign woman, which is why he allowed her to come on stage and approach him.
No one expected that this foreign woman was not showing her real face; she was in disguise after applying makeup and had assumed someone else's identity to carry out activities. Not only had the police conducting the security checks at the outer entrance failed to notice her suspicious identity, but even Yan Fei was deceived. He had inadvertently allowed this foreign woman to get close and launch a fatal attack on Lu Pingping.
