This was a heavily destroyed building.
The Space Science Research Center.
In truth, most employees of this place had been appropriately evacuated before the monsters completely ransacked the city.
Only the large-scale equipment was left behind due to how heavy and difficult they were to transport.
Everyone was already used to it.
Apocalyptic monsters were only interested in living people while completely ignoring artificial structures.
Because of this, after the employees inside had been evacuated, this facility only suffered a bit of external damage, once the monsters realized that there was no one inside, they immediately moved to find the next target.
In the underground basement of the research center.
Gu Qing Shan was controlling a few primitive mechanical arms to create advanced mechanical products.
Ye Ru Xi silently watched, then asked: "Has he always been such a workaholic?"
It had already been 10 hours.
