The first to arrive at the Big Butt Kunlun Mountain were still the thousand bandits from Breakback Mountain, led by Zayden Newton, each bandit an elite, and Zayden Newton himself was a Junior God King.
Sure enough, the third boss of Breakback Mountain was called Zayden Newton, coincidentally the same stage name as Yusuf Zuck had in the past. However, this Zayden Newton was bestowed by his parents, while Yusuf Zuck's Zayden was just a moniker.
The reason why Zayden Newton was called so because he was also a demon cultivator who ascended from the Lower Realm as part of the Black Bull Clan. This fellow was naturally endowed with immense strength and possessed Innate Divine Abilities.
Of course, don't assume the bull race is stupid, and don't think that being big is being weak. For Zayden Newton to become the third boss, to ascend to the Heavenly Realm, and even to achieve the status of Supreme Divine King, it indicated that he was monstrously talented.
