Li Pan glanced at the controls within the yellow zone elevator; the structure of the blue, yellow, and red warehouse areas was nearly identical. Upon entering from the hall, there was a direct elevator with floor number buttons totaling eight. The lowest level was the front desk reception lounge F0, and the seven other levels were arranged from F50 to F56.
Similarly, in the red zone, it went from F57 to F63, with the only difference being the elevator light colors, distinguishing them according to their corresponding blue, yellow, and red zones. If a floor contained a "monster," the corresponding elevator button would light up; otherwise, the space was vacant and could be used to store new products.
