In the Immortal Territories, particularly the Human Continent, the Master of Buddhism, Monk Taba, could be considered an entity with power that is near that of the Divine Emperor. He was also a Creator that used his authority to spread his religion and philosophy all across the land.
When the Divine Emperor met Monk Taba before he left, the former did not like how the latter spreaded blatantly all across his dominion without asking his permission.
When they fought, Monk Taba was of course defeated. But, recognizing his ability, the glorious Divine Emperor gave Monk Taba a piece of land in the western coast to preach Buddhism.
Although the Buddhist Monk lost against the Divine Emperor, it could still be said that his power could only be below that of the latter. Knowing that, and seeing how the mysterious person swatted the monk, everybody realized that they aren't dealing with just any opponent.
