Commander Tristan Nelson of the Herculean Army was a brilliant general. He led his army and conquered the northern area. Despite being powerful on the surface, Tristan had a weak spot. He almost died five years ago. Fortunately, he met a woman and had a daughter with her. On a day five years later, he got a phone call from his daughter asking for his help. Tristan had no choice but to withdraw from the battlefield and return to his family. Feeling guilty, Tristan decided to make it up to his family. However, his enemies wouldn't let him go. They did everything to destroy his family and stir things up in Dalton.
