The three knights obviously hadn't planned on dealing with Wang Yuyan, but instead surrounded Ye Wudao and attacked him. These knights wore armor similar to medieval knights, resembling a turtle shell.
Moreover, it seemed that their armor was blessed with some mysterious power, which reduced the weight, enhanced defense, and didn't burden them. Therefore, when Ye Wudao struck them, it only produced clanging sounds, unable to injure the knights behind the turtle-like shells.
The longswords of these three knights seemed to be imbued with a mysterious force as well, giving them more damage and a wider attack range than ordinary weapons.
But Ye Wudao wasn't serious; he was just playing with them. It was his first time clashing with Western knights, so he was curious to see their strength. Western knights were akin to the martial artists of Hua Country, prompting Ye Wudao's curiosity about how their strength differed from that of Hua Country's martial artists.
