After Becoming a Traveler, I Started Slow Travel

After the original girl Mio became a traveler, she descended her own clone and led her men to travel to the twelve dimensions under the Mio Sea. I travel in the twelve dimensions as a traveler and write my own travel story. As an observer, investigate the events and history of the twelve dimensions and record them. As a person of order, I maintain the order of the Sea of ​​Mio and the Twelve Dimensions. If any civilization comes to decay and cannot be saved, I will directly obliterate it.
