"Xaviera, we don't want to interfere with your decision, but I must tell you something – using your blood to detoxificate him is like burning your own life, and your lives will be intertwined. If he dies, you won't survive either!"
Xaviera remained silent.
"Do you know why Grandpa initially gave up on detoxifying Miss Drew with his blood?"
Xaviera looked up, knowing Grandpa's character, if he could help Miss Drew detoxify with his blood, he would unhesitatingly offer it. So, why did he give up?
"It's because Grandpa knew that using the blood of a miracle doctor, a Saint's Hand, to detoxificate would connect the lives of the two. And he was already in his sixties, maybe one day he'd pass away. Miss Drew was young. If it was done, her life would be shortened as well. So, he gave up, wanting to rely on his own abilities to help her, but he didn't expect Miss Drew to suddenly succumb to the poison and pass away, causing him to live in guilt for the rest of his life."
