[The law revered by the Demonic Cult is the Survival of the Fittest! Follow that law and ascend to the absolute highest seat of the Demonic Cult.]

Kunlun Never Forgets Its Grudges.
The sword of Kunlun never forgets a debt of vengeance.

"Very well. By the law of the strong that you worship so deeply, I will rise to the top and shatter every last one of you."
