Zhang Tie flew towards Yiyang City at the speed of 0.6 Mach. This time, he learned to hide himself by flying above 10,000 m behind clouds. Even in the sunny day, most of the people could barely find such a person flying above 10,000 m, not to mention a knight.
The head-on sharp airflow was blocked off by that invisible protective battle qi covering him. Therefore, Zhang Tie didn't feel chilly in the high altitude. When Zhang Tie was in the underground space, he had tried it. As long as he didn't accelerate to above 0.6 Mach, his battle-qi brilliance would not be exposed. That was to say, 0.6 Mach was his navigation speed and invisible speed.
There were many airships in the air. As long as he lowered his head, he would be able to see many of them. Because of the holy war, the powerful Jinyun Country being away from the north theater of operations seemed to become more prosperous.
