Over 3,000 large airships were 40 miles in length and 12 miles in width. The three large formations from 5,000 m high to 10,000 m high were like an eye-catching large cloud if someone watched it on the earth.
If it was not blocked by clouds, anyone could see such a giant slowly moving in the sky from hundreds of miles away. It was not difficult for demon knights to discover them because demon knights had much greater vision and senses than commoners. Those which could fly always had a good vision, not to mention wing demon knights.
As so many airships were flying in large formations, they couldn't move fast. Additionally, being affected by wind, all the airships could only move over 30 miles per hour. It was as slow as tortoise for knights.
Like how dogs liked chasing after frisbees, when wing demon knights caught sight of so many airships, they couldn't wait to bring down all the airships.
