Once everyone escaped through the door, only Suou and Jule was left to fight Lord Viliame. It was far beyond an easy fight. They both struggled until Jule is seen kneeled down to one knee trying to catch his breath.
All the guards were taken out in order to replenish mana, but at least they managed to weaken him to a certain degree. Suou was the one who could deal the last hit, the best way to kill a dark magician was using divine magic, but Suou only had his blood drain skill. It was the best way for him.
Jule stood once the lord was drained from all his mana, "that's one scary skill you have." He says as they both left through the door to the outside. Valera appeared with a worried expression.
"Thank the heavens you guys are safe!" She exclaimed after a sigh of relief.
"(Ding!), Quest completed! Generating reward."
