No way? Someone bugged the phone? Could Als have found her already?! With the Gestapo's power from all those years ago, bugging calls was no difficult task, but when Gu Nianzhi thought about it carefully, she realized it wasn't possible. If they had already discovered that she was here, Als could simply bring personnel to raid the place. Why were they lurking around and bugging calls? Gu Nianzhi was very anxious and didn't dare to make any calls again.
Apparently, Als had already accounted for any methods she could use to contact the outside world... With this fact, it meant she couldn't exactly trust the internet, either. If the enemy could bug a normal landline and cellphone, that also meant they could control her internet usage, and monitoring internet usage was far simpler than bugging a landline.
