"Ding!"
After the "ding", the two of them only saw the doors slide open on both sides, revealing an empty and clean hall outside the elevator.
This was a duplex-structure hall, occupying the first and second floors of the laboratory building. It covered an area of close to 5,000 square meters, almost like a small playground. Unlike other commercial premises, the decoration of the laboratory hall was minimalistic, mainly in white and silver.
It seemed that because it was already night, there were only a few dozen researchers in white coats in the hall.
Most of these people were assistants to professors. Some of them were walking toward the elevator with trays of medicines while others were unloading goods outside the gate from the trucks, ready to transport these biochemical agents to the warehouse. Some were also sitting on the sidelines, sipping coffee at the bar in the lounge area, chatting with other people.
