One week after establishing the new base, and with Stone managing the dual farms, there was no worry about food and warmth. The two Deputy Commanders led the team to the No. 2 exit of Sewer No. 99 again: a large shopping mall. Thanks to the team's adherence to the instructions given by Captain Maya, not only did they avoid a Night Demon ambush, but they also successfully counterattacked and killed the Night Demon.
After getting to know the layout of the underground parking lot, it only took the team 5 minutes to find the freight elevator. The elevator was stopped at the third floor. After prying open the doors, they used the maintenance ladder to descend to the first floor. Maya pried open the elevator doors slightly, took a look inside, then pried them open further, gesturing for everyone to come up.
