Cao Clan is one of the five great clans of the Pill Region. Of course, this clan could not be compared with the declining Ye clan. There seemed to be a never-ending number of talented alchemists in that clan. This caused the reputation of the Cao clan to grow greater. Other than the Dan clan, which kept an extremely low profile, it was likely that the Cao clan was the strongest among the five great clans.
Moreover, the Cao clan was considered part of the upper echelons of the Pill Tower. With this backing, even a faction like the Ice River Valley would not dare to easily offend them. After all, everyone in the Central Plains knew about the Pill Tower’s ability.
That was why the Cao clan was on the rise. The influence of the Pill Region was expanding. Compared to the declining Ye clan, one could be considered in the sky while the other was on the ground.[1]
