The mirage above Youzhou City could simultaneously manifest the battle situation in the Heavens Ball. However, as the Heavens Ball's space covered over 100,000 square miles, it could not be fully manifested in the mirage at the same time. Therefore, the mirage only manifested the battle situation in the eyes of the controller of the Heavens Ball, namely Commander Cheng.
Almost the moment Zhang Tie threw his first spear, the pair of eyes in the sky of earth-elements realm had narrowed and moved onto Zhang Tie. Closely after that, Zhang Tie's image in the pair of eyes was manifested clearly in the mirage. After that, everybody in and out of Youzhou City could see it.
It was like making a live aerial video using a special apparatus in a glider or an airship from a certain visual angle. When Zhang Tie showed his trump card thunder-in-palm, onlookers were really shocked.
