One method is to conserve torches, using only one at a time until dawn. Although there are still many dark areas in the sewers, the numerous drainage holes also bring in some light.

Being at risk of getting lost either way, everyone unanimously decided to adopt the second method. Shana asked everyone to keep quiet while she concentrated hard on recalling the path in her mind, and then she slowly took the first step. Maya quietly had someone extinguish the torches, leaving only two lit, and asked Lin Wu to be on higher alert. Although she spoke to Lin Wu, Maya's gaze was on Wai, something which made Lin Wu quite displeased: Does your man need you to earn face for him?
After walking for several tens of meters, Shana hesitated at a three-way junction. Cotton stepped forward, took over a torch, squatted, felt the ground for a while, and pointed down one tunnel: "This way."
"Reason." Shana asked.
