金庾信
The Goguryeo soldiers defending the castle succeed in fighting off the Allied Army's first assault by catapulting honey and bees onto the Shilla soldiers. Meanwhile, the Shilla grand general Kim Yushin (Jung Jin-young) holds back sending his main force to join the advance Allied Army, preferring to deal directly with Yeon Gaesomun's sons than the Chinese. Yeon Namsaeng is expelled from the castle by his elder brother. The Chinese commander Yi launches a full-scale attack on the castle but is beaten back by the Goguryeo secret weapon. An allied soldier, Thingamajig (Lee Moon-sik) from Baekje, is captured. Thingamajig, who has suffered under Chinese rule, broadcasts a demoralizing message to the Allied Army. Thingamajig is rewarded by being allowed to marry the brave Goguryeo female warrior, Gap-sun (Sunwoo Sun), against her will.
