The spiritual arrays in this place were quite ambiguous. Tang Yin was reminded of the spiritual arrays that were in that second-level empire. There was not much difference.
But, the people inside the palace were not as weak as those.
One way to distinguish first-, second-, and third-level empires is to be guided by the most powerful people in each of them.
If it is a Spiritual King who is the strongest, then it is a third-level empire, the lowest. And it goes up one level with each ascended realm after that.
That means that, in a first-level empire like this, the most powerful people are people of the Saint Realm, and it is the same in all.
In fact, there is no first-level empire that has a Spiritual Supreme.
Although many spiritual supremes have been born out of these empires, all of those achieved their strengths only because of the great sects.
