Some men make a white flag of peace, and climb into the pit. There's a flash of light and the men are dead, burnt to ashes!!
They were building some kind of heat ray! They fire it at the people closest to the edge! They didn't stand a chance!
The heat ray then burns the trees behind them! It just misses the heads of the rest of the crowd! Then it hits buildings, and they crumble! I have to get out of here! Now!
