The golden core elder didn't believe the promise made by the speaker on the other side of the communication talisman.
She asked in anger, "Do you take me for a fool? Do you think that I do not know that you will discard me after you have won and have no use for me?"
The voice assured her by saying, "You don't have to worry about that. I am a man of my word. Besides, I have also sworn an oath by the Ethera tree."
This claim only made the golden core elder scoff and say, "I don't doubt you. The people I doubt are the people of your sect."
"So you've sworn an oath. That doesn't mean that the oath can't be broken. It only means that the consequences for breaking the oath will be severe or even lethal. If you gain more by breaking the oath, you will do so."
