Two surveillance cameras had been posted at the Xinjiekou intersection for 144 hours, tirelessly working over the past nearly one week. They sent the captured images to the wireless router, which aimlessly broadcasted them outwards; if someone received them, good, if not, so be it. They charged every morning as the Sun rose, working while charging until sunset, and after nightfall, their batteries could last a maximum of four hours.
"BG, I'm about to switch the link and will enter silent mode."
"Roger that, OVER."
"I want to confirm one last time, from now on, I will move to an underground shelter, stay away from Meihua Villa after the nuclear explosion, enter a safe zone and stay there for a week. Only after a week can I return, right?"
"That's correct."
This meant that Ban Xia would be out of contact for a full week. Before moving, she switched the data link of her Icom725 to the wireless camera, so she wouldn't be able to change it back until a week later.
