Chapter 406: Chapter 406 In The Sewers

Once one soldier mentioned the possibility of the noise emanating from the walls, the others quickly reached the same conclusion.

City B had long been a hub for merchants, with many families residing there for decades.

Given the nature of their work, these families often faced constant threats to their safety, as someone was always lurking, ready to rob them of their wealth.

It was likely that many families had constructed their own bunkers, hidden rooms, or compartments in their homes as a precaution against such threats.

Therefore, it wouldn't be surprising if zombies had become trapped within the walls of these houses.

Once they settled on this explanation, the soldiers began tapping on the walls, searching for hollow spots or hidden switches.

It took them two long hours to inspect just five houses. Fortunately, these homes were not large, typically accommodating only a middle-sized family.
