The first man became excited when he heard the bird calls. He said with visible excitement, "That's the signal. Let's do it."
The second man was already moving to execute the next part of the plan. When he heard what his partner said, he said, "Are you coming or not?"
The first man replied, "Let me send back the bird call first."
He sent down another set of signals to tell their subordinates that they are about to execute the next plan of their action. Then he went on to continue with the other man.
Both of them moved quickly. They took up axes and used them to cut the sticks used to secure the stones blocking the entrance of a cave.
The entrance of the cave was blocked by a large boulder. The boulder was reinforced with thick, short tree stumps used to prevent the boulder from moving.
Now that the tree stumps were removed, the boulder could finally roll out of the way for what was in the cave to come out.
