This directly relates to Tang San's slaying of the Diamond Elf King. Both the Blue Gold Tree Clan and the Soul-Stealing Spirit King believed that it was the Tree Ancestor who killed the Diamond Elf King, but as a part of Tang San's body, the Crystal Great Demon Emperor thought otherwise. She personally witnessed how Tang San meticulously set traps for the Diamond Elf King, eliminating an emperor almost risk-free at rank 11 of cultivation, utilizing all available resources and abilities. This made the Crystal Great Demon Emperor truly recognize him as her master.
The Crystal Great Demon Emperor, once the strongest being in this realm, is undoubtedly proud. When she initially chose Tang San, her purpose was mostly to use him. But now, she has revealed her true talent to Tang San and is fully supporting him, marking her genuine recognition of him.
