Chu Hao battled the September Realm Master.
In terms of mastery of the Laws of Five Elements, he was still at the level of a low-tier Domain Lord, hence he could only fight low-tier Realm Masters, but he could definitely crush the September Realm Master without any suspense.
However, Chu Hao did not go all out. He only deployed a portion of the Might of the Laws, fighting the September Realm Master to a stalemate.
This left the September Realm Master extremely shocked. Just a mere Domain Lord, how could he be so formidable?
Being a battle at the Realm Master level, it naturally shook the heavens and the earth, rapidly attracting various powerhouses who watched from a distance.
That was exactly the effect Chu Hao wanted—to show everyone his power, to make his words more persuasive.
