Liu Xiao Zhou is the son of a Vice Mansion Master of the Martial Battle Mansion. Although he was not as strong as Heng Feng, he was someone who had comprehended five profundities from the law of metal and was in the process of comprehending the sixth profundity. His highest rank on the scoreboard of the middle realm of the Southern Heaven Ancient Realm was 69th place. It was incredibly rare for a Ten Directions Celestial Duke who had merely comprehended five profundities from a law to make it into the top 70. This could be attributed to him comprehending the law of metal as well. If he were to comprehend the law of earth, he would not even make it to the top 80, let alone the top 70.
