With a fire hawk watching overhead, Li Yao was like a man with satellite navigation; even if his view was impeded on the ground, the sky was unobstructed.
Moreover, the fire hawk flew exceedingly high, so the occasional trolls riding wind snakes across the sky failed to spot it.
Although wind snakes could fly, they were not particularly good at transportation. Riding a wind snake was inconvenient, and trolls only occasionally flew on them. But it did barely constitute an aerial defense system.
Of course, underestimating the combat strength of a wind snake would be a grave error.
While they were difficult to ride, wind snakes could fly extremely quickly on their own. Furthermore, as magical creatures, they can cast wind and lightning magic, making them tough opponents.
