Tortoise is a planet with constant disputes, and it is almost the two extremes of Celestial. In the world of Tortoise, everything is extremely aggressive, because… In order to survive, is through constant plunder.

Tortoise is the planet with the poorest land in all of Long Sector. There are deserts all over the place and sparse vegetation. The creatures that can survive on Tortoise have their own set of skills. However, the metal minerals on Tortoise are surprisingly rich, which can provide a large amount of armor and weapons for war. This makes Tortoise, which is already experiencing constant wars, become more dangerous than it already is. In addition to the harsh environment, there is also an extreme climate on Tortoise: dry wind. The dry wind is a storm that blows up from time to time, which can sweep away the spiritual energy in living creatures. No matter how deep they hide, they will be affected. There are only a limited number of places that can help Tortoise people resist the dry wind. The dry wind is cruel, but there are few shelters that can block it. In order to be able to compete for these sanctuaries, all the forces competing for the sanctuaries will each send a representative to have a duel under the watchful eyes of all tribes. The winning tribe will get the right to use the sanctuary, while the loser can only leave and find the next one. Shelter, or quietly waiting for the cruel dry wind to come.
