Lee-kyung, searching for the materials to evolve his skeletal servant, ‘Lackey,’ was barely able to participate in a high level raid for [Tower of Command] Dungeon. In an accident, he falls down alone to uncover a hidden conspiracy. Injured and desperate to survive, Lee-kyung called out to anyone…and reached a vengeful spirit. “Please, I’ll do anything….Please form a contract with me and save me!” –-You’ll do anything?…. [Will you accept the ‘oath’ offered by ‘Seo Dawon’?] –-You’ll do your best to help me achieve my revenge. And, I will do my best to save you wherever, whenever you are in danger. Is that acceptable?   [Initiating a new contract with ‘Seo Dawon’] Junior Necromancer Choi Lee-kyung and Ranker Mage Seo Dawon’s delightful revenge play! !Warning!
