Which is more powerful, the Seven Killing Hall or Changliu Mountain?

The Seven Killing Halls are awesome.

Changliu Mountain is famous and decent, but its cohesion is not as good as that of Seven Killing Halls. The main hall of Sha Qianmo, the master of the Six Realms, is the Seven Killing Halls, which is a mysterious and aloof palace. There is a huge energy hidden there. If you touch it carelessly, it will make you invincible. The protector of the Seven Killing Halls is Shan Chunqiu.

Changliu Mountain and Seven Killing Halls are two schools in the TV series Hua Qiangu, both of which have considerable strength.
