The wind was blowing hard.
Dugu Xian ordered the first 10,000-men army to launch their attack. Flags fluttered as gusts of wind blew through them, and the sounds they made were so loud that they nearly drowned out the rumble of the horse hooves. The troops in the rear could only feel the shaking ground through their mounts.
Horseback archery was all about distance. Only when the distance was right could the Norland cavalrymen freely launch attacks on their enemies while keeping themselves safe at the same time. When two such armies engaged, the battlefield naturally became exceptionally vast. Even if there was only a small amount of dust in the air, the two sides would easily lose sight of each other.
