The human civilization of the Flying Star Sector was based in space. It was troublesome for people to communicate with each other. Therefore, Cultivators of this Sector had focused much attention on the development of the Great Illusionary Land and the Spiritual Nexus.
Cultivators of the Flying Star Sector had refined countless Spiritual Towers that could absorb the spiritual energy in the universe automatically and launched them into the sea of stars over the past thousands of years.
With the Spiritual Towers in space as nodes, the Spiritual Nexus gradually expanded and covered most of the Flying Star Sector. All the people were finally linked.
For the Cultivators of the Flying Star Sector, they had developed countless Great Illusionary Lands on the Spiritual Nexus as platforms where they could talk with each other about training.
Sword Cultivators had their own platforms, and so did Spiritual Tattooists, Grand Illusionists, and any other professions.
