After having seen the fight between Changli Mountain and the Blood Dragon Sect, Yan Zhaoge had already gained a general understanding of the relationship between the so-called Seven Pillars of Good and the Six Evil Sects in this Vast Ocean World.
Good and evil were diametrically opposed, but powers under the same camp also had their own enmities and grudges in private and would battle it out once in a while. It was just that when the two great camps were clashing, those in the same camp would likely be able to forget about their differences and work together in concert.
While Yang Chufan and the others had not made it clear, Yan Zhaoge could still venture a guess.
Spirit Rhino Island was most likely one of the Seven Pillars of Good alongside the Blood Dragon Sect and Changli Mountain, all of them being enemies with the Evil Shifting Sect of the Six Evil Sects.
