"Grandfather, why don't you help him get rid of the Affection Gu Worm." Priestess Pleaded.
"Are you stupid? This is absolutely impossible." The Great Priest shouted.
Priestess knelt heavily on the ground and said, "Grandfather, I know you have always loved me since I was young. But this time, I bed you to let him. I don't want him to die with me. He is innocent."
What caused the Priestess to make the decision to bed her grandfather to expel the poison for Feng Yun?
Part of the reason was because the Priestess was kind in nature. Another important reason was that Feng Yun was able to control his own desires and did not harm the Priestess.
If Feng Yun could not control his own desires and slept with the Priestess, then the poison in the body of Feng Yun would have an effect. This would make him forgot about the women in the past. He would only wholeheartedly love the Priestess.
