Originally, the experts of the Jiangs had set up a defense on the outer perimeter to protect these array masters.
This was because the key to this array not being broken was not Chu Yunfan, who was inside, but the array masters outside. As long as the array masters were fine, unless Chu Yunfan's strength had already surpassed theirs, it would be very difficult to break through.
And according to the original plan, that barrier was only used to trap Chu Yunfan for some time. After that, there would be advanced mechas using all sorts of heavy weapons to bombard him indiscriminately. It would only minutes. However, the originally perfect plan had suddenly become flawed because of Jiang Dan's momentary complacency.
He had been delayed by Chu Yunfan, and thus had been left behind in the formation. This had made those advanced mechas afraid to act recklessly.
