As the first raid team had started their progress, the rest of the raid teams that had already been assembled were also being teleported to various areas of the Zombie World.
Egypt, France, USA, United Kingdom, Australia, United Arab Emirates, Philippines, and China were the places where Jin had created the hideouts for them to participate from. He wanted to have more places for the raid teams to try out and branch out from there but those were still considered to be limited especially when Jin was only relying on his Grey Bears to scout for the hideouts.
Yet, those hideouts were sufficient for now as each country mentioned had at least two locations where the raid teams started their exploration. For example, Xiong Da and the others were in the supposed outskirts near Badaling City while the next location was ironically, Qian Liu Town as well.
