After three hours.
Sam started placing the strongest warriors Giyon has at her disposal at different positions all around the dome and he marked the points on the dome that they should be attacking.
He also gave them a communication device each and started giving them orders.
After everything was set up, he looked at Giyon and said.
"The warriors will be attacking when I order them to. There would be an opening in which I would be entering the dome.
Exactly after seven minutes and twenty-nine seconds, tell them to attack the same points again.
At that moment, the barrier would collapse, but make sure that you guys are not attacking it any time sooner or later. It needs to be perfectly on time without a single hitch. Otherwise, it wouldn't work, and also be careful about the attacks that are trapped.
When the dome collapses, they might randomly hit different spots.
