Dream Tower consisted of 45 floors above ground, with floors 1 through 43 serving as offices and logistic support for various departments of Dream Technology. The 44th floor served as Yan Fei's private warehouse, and the 45th floor, the top of the tower, was Yan Fei's home.
To ensure Yan Fei's safety, the space between the 43rd and 44th floors was completely sealed off. Even the elevator couldn't go up there, and only a single door separated the upper and lower areas. To enter this door, one needed not only a password but also to pass facial recognition, and only those authorized by the security system could enter.
