The Supreme Palace is the only legitimate Immortal Sect within the Saint Land.
It's called the legitimate Immortal Sect because the Supreme Palace has nearly tens of thousands of people, with thousands being Immortal Warriors or above.
This massive cultivation force is also a continuation of the legacy from the four ancient Immortal Emperors, as the Western Desolate Saint Land used to be a true cultivation sanctuary, gathering cultivators and being incredibly prosperous.
Though the four ancient Immortal Emperors eventually left, they left behind many precious cultivation resources, such as Immortal traces, Immortal arrays, and Immortal treasures.
Even though many Immortal treasures have been lost over the long years.
The Saint Land remains the best place for cultivation.
Therefore, the Supreme Palace has been preserved.
