Earth Year 2049. Human Civilization is entering a new phase. Humans now chase after a new goal. Climbing Tower of Transcendence and finding what is on the summit. Arman with his party were the world's leading adventurers who were attempting the final floor, the 100th. Humans believed that the 100th floor must be the final but no one knew for sure. There was no rule, no guide, no administrator for this tower as one would expect since tower system was similar to ones from novels. Humans could only guess about the purpose. As soon as Arman and his party enter 100th floor, they are killed. Now Arman wakes up only to find that he is in a body of an administrator for Earth and learns about the calamity is scheduled to befall, and he is allowed to reset Earth by Four years, right when the Tower was first discovered as his Admin privileges as a one time use. While Admins are supposed to be unbiased, he must help his home planet and himself as the Climber within the tower without being caught and he must also find out who killed the original admin.
