It's been a few days since the big reveal, and the gang is finally back at work. They've confirmed that the three neighborhoods they're looking for are less than five kilometers away from the current location. The first building is a new one, and it's got a low occupancy rate. The other two are older buildings, which have a higher occupancy. The front gate of the new building is under construction, so it'll be even more difficult for them to get in. The third building is an older one, so the occupancy rate will probably be lower. The reason why they went to the older buildings is because there's no manpower to search through the whole building, so they'd have to go by instinct. They can't search through all the apartments by themselves, though, because there are so many dust particles on the floor. So they'll need two teams to go through each apartment and check it out. The guards at the two older buildings say they didn't see any people entering the apartment last night. They also found footprints in the front of the apartment, which means that they've been hiding there all night. The three of them split up and check the apartment for footprints. There are lots of footprints heading up to the fourth floor. The chase team is so scary, and everyone is freaking out.
