Opposite to the latitude in which we live, there is another latitude beyond current technology, which is called the opposite.
It is the opposite side of the normal latitude. People will come here when they die from the front or trigger a key point. However, one of its characteristics is that the people who come here are all teenagers, young people and middle-aged people, and they will all be concentrated in the ninth space, which is the lowest level at the beginning. From there, it progresses layer by layer. When the accumulated points reach a certain level, they can freely come and go through the nine spaces.
(Fate update)
Nan Yan is the manager of one of the latitude spaces. The space he manages is the easiest among the nine spaces but has the highest mortality rate. This is because he was born independently from the space and his thoughts are integrated with the space.
Each space has a management system, which manages daily things and connects various space systems.
