"What can we do, then?" Kai asked, "If we can't get an army to help us defend this place?"
Finley could only think of one thing. "We need to make sure the barrier is not disabled. You said they are already inside, right? So we need to act like we don't know they are here, and figure it out things."
Kai liked the plan. The worst part about the invasion was the barrier getting shut down. When that happened, it was just too easy for the army to enter the school, and for the artillery weapons to destroy everything.
If they kept the barrier running, there was a chance of holding up.
"How long can the barrier last against an army?" Kai said.
"It can last for days. Not only that, but we have artillery weapons too, so we can kill the army while being inside this safe spot," Finley said.
