Coincidentally, the moment Zhang Tie flew out of the mountain cave, one of the escaping airships had rushed towards him, which was also the target of the wing demon knight.
The airship was firing steam bolts towards that wing demon knight.
Honeycomb-type steam ballista could fire hundreds of bolts at the same time. The huge bolts fired by the main ballista at the stern were as powerful as whale-hunting harpoons.
However, due to the great difference in levels, the counterattack of the crew members looked pretty weak.
The honeycomb-type steam ballista and the main ballista might threaten demons below battle spirits, but they couldn't even break the protective battle qi of demon knights, not to mention a wing demon knight. Without the protection of human knights, it was impossible for human airships to defeat wing demon knights who were dominating the sky.
