The city was still covered with flames while the airships that scattered just now had already gathered in the distance and started to fly eastwards once again. An airboat was suspending above the burning city. All the demons had disappeared. The 3 earth human knights who chased after demon knights just now had already returned. When Zhang Tie flew back from afar, he saw many human knights flying towards him.
The bloody head of the earth wing demon knight in Zhang Tie's hand indicated Zhang Tie's military exploit. At the sight of that bloody head, all the human knights watched Zhang Tie with evidently respectful and admirable looks.
If not Zhang Tie's timely arrival, it was hard to say how many people among these human knights could survive.
