Korea-Khitan War Episode 6

This review contain spoilers.

I didn't know what to expect when I watched the last episode's ending scene, but Goryeo's counter-attack to Khitan's first move was so unexpected and cool. Yang Gyu is the star of this episode. I thought Yang Gyu was scared of the fireballs Khitan aimed at the fortress, but turns out he was calculating the position of Khitan's arms. He's a capable officer and warrior, and I hope he will not turn into an antagonist. When he looked at Yong, I think he was thinking of his son.
