Although Yu Qingqian's words were expected by Yu Changfeng and the boy, they couldn't help but be disappointed.

  The boy has been used to this kind of disappointment for so many years, so it was only a short time and passed away in an instant.

  But Yu Changfeng sighed heavily, as if he was hit.

   If even a great-granddaughter who understands poison so well can’t solve this poison, does that mean that the life of an old friend is really likely to end in about twenty years?

   For people like them who have lived for tens of thousands of years, twenty years is just a time for retreat.

  Yu Changfeng thought for a while and asked again: "Xiao Qianqian, you can't solve two toxins, so can you solve one?"

"Since the old guy's constant loss of life is caused by the fact that two toxins want to devour each other and have opposite properties, does that mean that as long as one toxin is solved, this problem can be solved?" Yu Changfeng thought. Maybe this way works.

  Yu Qingqian didn't want to discourage his great-grandfather's enthusiasm, but he could only tell the truth, "No, if that's the case, once one of the poisons is removed, senior will die."

   "Why?" Yu Changfeng frowned deeply, puzzled.

Yu Qingqian replied without hesitation: "If the senior just got rid of a toxin within ten years of being poisoned, then just like the great-grandfather said, the hidden danger is just a poison, not a double effect leading to longevity. Yuan gradually decreased."

"But the senior has been poisoned for ten thousand years, and the two toxins are even more familiar with each other, and the fusion of each other at regular intervals has created an indispensable situation, so once one of them disappears, it also means that the senior will suffer. Affecting the sharp decrease in vitality followed by disappearing."

   "Similarly, if it wasn't for the brief fusion of the two toxins, the senior's lifespan would not be steadily and slowly passing away, but would suddenly decrease." She added, "So it is a good thing to have two toxins now."

   Although Yu Changfeng didn't understand healing techniques and potions, he understood Yu Qingqian's explanation very clearly.

   He couldn't help sighing again, but this time he responded with silence.

Yu Qingqian and Feng Chen didn't feel very well when they encountered such a situation. After the conversation just now and the other party's peaceful and unreserved advice, and looking at their great-grandfather's undisguised expression of discomfort and disappointment, they also gave birth to a kind of feeling. I don't want the feeling of the other person dying.

   Instead, the young man was more open-minded and open-minded. He reached out and patted Yu Changfeng's shoulder, "I don't care anymore, why are you so uncomfortable?"

   "Hmph, we've known each other for so many years, even though we're just friends of life and death, we're better than brothers. Of course I don't want to see you die in front of me." Yu Changfeng snorted coldly, but he couldn't help but feel sad.

   "Who can be like you now, with no temper and no emotions, and as pure-hearted and careless as a monk who has been a vegetarian for many years."

   "I can't do it." Yu Changfeng snorted again.

   Although their experiences are different, they have many similarities. They have worked together for many years, and this brotherhood is hard to give up.

   The boy gave a wry smile. He didn't want to live such a life, but his habit was gone. He had experienced so much, and he really looked down on life a lot.

  Yu Qingqian didn't pay attention to listening to the two of them, and kept thinking about whether there was any way.

   Suddenly her mind lit up, and her originally gloomy eyes lit up, and she said, "Maybe there is a way to try it."
