Rather than a laboratory, Peter's workplace was actually more like a research center.
As they went deeper into the facility, just on the way to the lounge alone, Nora observed that there were already about a few hundred people guarding the place. From the looks of it, Peter and the others were doing research on something extremely important.
There were also a lot of employees—at least a thousand of them—in the research center.
Therefore, the research center had its own employee dormitories and canteen.
The families of most of the people under surveillance also lived and worked there, so they couldn't leave even if they wanted to.
When they reached the lounge, Peter said, "Rest here. I'll bring you guys around and let you meet those people when lunchtime comes. I'll give them a heads-up first, too."
"Okay."
