As for not being able to kill Cao Zhen?
They never considered this problem.
Their Immortal Mountain all exceed six thousand zhang in existence, and besides, they are of the Sky Clan, the most powerful Sky Clan!
Although Cao Zhen is strong and can annihilate the Peak Immortality Regainment Realm with an Immortal Mountain over six thousand zhang, he will also die when he meets them!
As for the other Human Tribe members, they are even more disdainful, as one Immortal Mountain after another emerges behind them.
Among the four Sky Clan members, the one with the tallest Immortal Mountain is actually a female Sky Clan in a white robe, reaching a height of six thousand eight hundred zhang. The remaining three, the shortest Sky Clan's Immortal Mountain also reaches six thousand one hundred zhang, and the other two male Sky Clan, both Immortal Mountains are six thousand two hundred and fifty zhang in height.
