Ning Qingman, when commenting on the world's strong contenders, once said to Li Fei that aside from the princes of the Western Continent, there were a few top-level True Men whose power posed a threat to him:
The Deputy Sect Leader Wu Hui of the Yuhua Sect.
The Daman of the Grassland's Man Yuan Sect.
And one more, Wu Che of the Pudu Temple.
These three all have combat power comparable to the princes of the Western Continent!
Between the Great Grandmaster and the Martial Saint, and between the top-level True Man and the True Monarch, there is no transitional realm.
Thus, the Eastern Continent does not have a realm corresponding to a prince; to break through the limits of the realm, one must use special methods.
For example, Northern Barbarian King Bo'erhu relies on unique beastification, and Daman relies on the power of faith.
Wu Che relies on his second lifebound magic artifact.
