"The so-called residue is actually what's left behind from the heavenly materials and earthly treasures you normally consume, the resistance built up from taking medicinal pills-in other words, the obstructions I mentioned earlier that the Feitian Realm burns away...

At your current stage, taking one drop can clear everything out, leaving no impurities."
Zuo Changlu said, "In other words, after taking it, your bodies will be completely clean, and when you consume similar things later, you'll still be able to benefit from them... Understand?"
