Under the surveillance of the laptop's camera and microphone, the Auxiliary Brain suddenly detected someone knocking on Yan Fei's door and immediately informed him of the situation.
Yan Fei was shocked to discover that someone was knocking on his door. At this time, it was past midnight in Paris, already deep into the night. Moreover, it was a wild, stormy night in Paris, with lightning and thunder, essentially keeping everyone indoors and putting a halt to the usual vibrant nightlife. At this hour, no one would typically be out and about. The personnel Yan Fei brought to Paris had already gone to bed early; they would not be the ones knocking at his door. Therefore, someone knocking at this time was definitely not normal.
