Excluding ventilation ducts, the 'Factory' has a total of three entrances and exits, each heavily guarded, especially during such a special period now. To prevent saboteurs from escaping, not only are the entrances and exits more strictly defended, but the ventilation ducts will also be sealed.
So whether Luo Yirui will suffocate, no one knows, but Dad told him absolutely do not go through the ventilation ducts anymore.
Where is Dad, he won't be in trouble, right?
Luo Yirui remembered when the communication was cut, there seemed to be gunfire over there, which made him somewhat worried.
Their location should be at the very southern end of the 'Factory,' belonging to the top-secret area, which is also the most strictly defended area.
So they are very unfortunate; a wrong step could lead to being trapped like fish in a barrel...
