章 164: The Attack (III)

Mark stopped once they reached the end and looked into the corridor. It was simple, and as the man said before, the stairs were literally right next to them. But there were also 4 people surveying the place, always on alert and looking around. Taking his head out, Mark couldn't help but sigh. It was almost impossible to use the stairs with no noise and people not noticing. 

Leaning against the wall, both of them calmly waited for someone to reach the end of the hallway. Finally, after a few more seconds, they could hear footsteps getting nearer. As soon as the person's head became visible, Mark immediately pulled him into a headlock and dragged him to the side.
