"There are five guards at the front." Qiu Shou whispered to Lin Ze, Qiu Si, Ji Ren, and Yu Ling. "How do we pass by them without alerting them?" he asked them.
They are the vanguard group. Even if they are here to attract the enemies' attention, they naturally wouldn't be stupid to just charge straight into the enemies' camp, especially when they only have five people with them with one of them (Qiu Shou) as a support. As to why they didn't count the Practitioners Alliance members and brought them with them? It is because there was just a handful of them left after they found out that some of them were killed by the enemies to replace them for infiltrating them. So, Lin Ze gave them a task to watch over Yue Xiaoxue and Gan Qiong, as well as Lin-lang and Mi Ha.
