Although the Basic Bloodline Talent Improvement Liquid is relatively scarce at the moment, if necessary, it can be replaced with the Bone Marrow Purify Pill and the Infinite Treasure Pill. The Infinite Treasure Pill has better effects; the only issue is that it's too rare and expensive.
As of now, not only is the family's alchemist Wang Shouye incapable of refining it, but even his master, Master Dan Ding, cannot yet produce it.
Wang Shouzhe had already investigated thoroughly. Some of the Infinite Treasure Pills auctioned off in the auction houses are circulated from Lingyun Sacred Land, while others are imported from the Cold Moon Immortal Dynasty. It's said that the price in the Immortal Dynasty is considerably cheaper than here in Daqian.
Coincidentally, Liyao's master, Celestial River Zhenren, plans to take Liyao to the Immortal Dynasty for some experience. If, during this opportunity, they can find a small supply channel for the Infinite Treasure Pill, that would be ideal.
