After thinking for a moment, Peter Brown put away the Heaven-turning Thunder, and while flashing around, he launched a formation disk around the Imperial City one by one.
It was a Ground Shield Formation that Peter had just obtained from fighting Alvin Smith's Army. Actually, the formation was not difficult, and Peter's Ring had a lot of materials that could be used for refining.
Launching the formation disk on one side, and refining on the other side.
Peter Brown had set up the formation around the Imperial City.
With such a formation, even if the Heaven-turning Thunder was powerful, it would not hurt the mortals within Kingston.
After activating the formation, Peter nodded secretly. With the existence of this formation, the power of the Heaven-turning Thunder would be reduced a lot.
Originally, Peter was thinking of using two Heaven-turning Thunders. Now he just wanted to kill some of the people inside.
With a shake of his hand, Peter threw out a Heaven-turning Thunder.
