The strength of the Grand Sky Sect is indeed important, but it's merely a stepping stone to ascend to the Grand Sky Sect!

Becoming the Grand Sky Sect is easy, but maintaining that position is incredibly difficult.

The success rate of a sect's disciples is a crucial factor in determining how long it can hold its position as the Grand Sky Sect.

Take Martial Emperor City, for example. Its current strength is only second to the Grand Sky Holy Land, so it's rightfully the Grand Sky Sect.
