Right now as you can see Allen was using his keen observation technique to advance in that place. First of all he only knew some of the places where that person put those traps but unfortunately he did not know about all those places so naturally he needed to advance very carefully right now. But at the same time as you can tell he also needed to advance toward that place while hiding himself from those rough Warriors who were guarding that place.
Fortunately you can say that place was full of trees and right now Allen was using them to hide himself while advancing very carefully. Naturally he could already go to that warehouse if it wasn't for those traps so before anything he wanted to make sure that he did not get caught in any of those traps. After that he already plans to use The Spiritual Tiger technique to take care of all those people right now.
