All he needed to keep were the top-quality ones for his elders. In Su Yu's eyes, if it was for his elders, it should be of the highest quality, ensuring a hundred percent chance for them to achieve better condition and attempt a breakthrough.
If the ordinary-grade Ming Shen Pill were not needed, he wouldn't want to keep it and risk exposing its existence.
"One for the Master, one each for Elder Su Chang and Elder Su Ruosu. Three top-quality ones will suffice," he reasoned.
"As for the Family Head, his age is not a major issue yet. We can wait a year or two to collect new ingredients for the Ming Shen Pill, and then refine a top-quality or even a perfect-grade Ming Shen Pill. At that point, it would be even better for him to attempt a breakthrough."
However, Su Yu hesitated for a moment, finally deciding to suppress this thought for the time being.
What if he couldn't gather the new ingredients?
Then, destroying this one would be foolish.
